As a society, were recognizing the need to become more sustainable and leave behind a better world for future generations. Educators in particular see the promise of tomorrow reflected in their students faces every day. Its no wonder that school administrators are seeking new ways to make their schools cleaner, healthier places for youth to learn and grow.
However, environmental concerns are not the only reason why schools are going green. According to the Department of Energy, educational facilities use a combined 820 trillion Btu of energy annually and that energy comes with a high price tag. Faced with ever-tightening budgets, schools must find new ways to simultaneously reduce their energy expenditures and their environmental impact.
Many school administrators and facility managers are familiar with recycled building materials and energy-efficient heating and cooling systems. Schools often order from suppliers such as National Air Warehouse for their efficient heating and cooling systems. Fewer are aware that propane yes, propane can also their reduce energy costs and their schools environmental footprint. For more information on propane’s many uses, you might want to check out somewhere like Propane Arizona as they may be able to provide you with a helpful guide to the alkane.
According to Bridget Scanlon, director of residential and commercial programs for the Propane Education & Research Council (PERC), propane is a cleaner-burning, lower-carbon fossil fuel. Compared to natural gas, propane has a near-zero direct global warming potential, Scanlon says. Propane also emits fewer than half of the greenhouse gas emissions that electricity does, considering that most electricity is generated by coal-fired power plants. From the financial aspect, propane prices have fallen substantially in many U.S. regions when compared to prices for gas, diesel, and heating oil.
For all those reasons and more, both new and existing schools can benefit from propanes energy efficiency and smaller environmental impact. Considering propanes many other convenient advantages, its a smart choice for a wide variety of applications.
Space heating: Propane can warm buildings quickly an important benefit for schools cycling through occupied and inactive periods. Energy-efficient, propane-fueled space heating systems consistently cost less to both purchase and install than heating-oil systems, air-source heat pumps, or ground-source heat pumps. Converting existing space heating systems to propane is fast and easy with heating unit change-outs. These change-outs significantly reduce initial conversion costs and leave existing heating-distribution systems intact.
Water heating: Whether heating water to wash cafeteria trays or provide showers for school athletes, propane tankless water heaters are extremely efficient. These unique on-demand systems can reduce energy costs by up to 50 percent and reduce greenhouse gas emissions by up to 61 percent. When someone opens a hot-water tap, the unit senses the demand and starts the heating process, said Scanlon. Schools dont have to waste money keeping a tank of water hot when theyre not in session.
Appliances: Propane cooktops and stoves provide better heat control and instant flame turn-off, preventing overcooking and improving safety. Propane ovens also help foods retain more moisture than electric units a major plus for schools that must keep hundreds of meals warm and appetizing. For schools with their own laundry facilities, propane-powered clothes dryers dry items faster than electric units and produce a moist heat thats gentler on fabrics.
Grounds maintenance: Using a propane-fueled commercial mower for school landscapes is a smart decision, both financially and environmentally. Compared to gasoline or diesel in certain markets, propane is more cost-effective. Propane is also cleaner, reducing greenhouse gas and smog-forming emissions by 50 percent. Those cleaner emissions improve engine longevity, reducing maintenance and replacement costs.
Fleet vehicles: School buses fueled with propane autogas produce 20 percent less nitrogen oxide, 60 percent less carbon dioxide, and 18 percent fewer greenhouse gas emissions. However, they still provide the same horsepower and torque. FleetsandFuels.com recently reported that an Indiana school district saved more than $10,000 in fuel costs in a single year after it began using just five propane autogas buses.
Generators: Student safety is always a top priority. Propane-fueled combined heat and power (CHP) systems and smaller micro-CHP systems can literally save the day in the event of an unexpected power outage. CHP systems recover waste heat from the generator engine and redirect it to produce space heat or hot water for locker rooms and cafeterias, Scanlon adds. Theyre an excellent example of the innovative new technology thats now available for schools, homes and commercial buildings.
These systems may also generate excess electricity, which a school can sell to its local electric utility for an even greater return on investment. Standby generators are another propane-fueled option that schools can combine with solar, wind, or other renewable energy resources to create reliable, environmentally-friendly hybrid energy systems.
PERC is making propane an even more attractive alternative with its Propane Heat & Power Incentive Program, a nationwide initiative that encourages residential and commercial sites to adopt energy-efficient propane-fueled products. Participants can receive up to $10,000 toward the purchase of premium generator sets and micro-CHP systems in exchange for reporting performance data to PERC, Scanlon says. Feedback from the program will be used to supplement future product development and research.
Propanes many energy-saving, budget-friendly and environmentally-sound applications make this alternative fuel worthy of consideration by educational facilities everywhere. For more information about how propane can help schools be green and save green, visit www.buildwithpropane.com.

DAYTON, Tenn. — Students at Rhea County High School will have a new state-of-the-art building for the 2013-14 school year after construction work concludes on a new 230,000-square-foot structure. Meanwhile, renovation work on the existing 144,000-square-foot structure will be completed around the same time, creating a new middle school, which will lower the burden on local elementary schools and give sixth, seventh and eighth grade students their own space to experience the transition from childhood to becoming teenagers.

The new school was designed by Michael Brady Inc., based in Cleveland, Tenn., while Hewlett Spencer, LLC, out of Nashville, Tenn., served as the construction manager under a construction manager at-risk agreement.
The combined renovation and construction project, coming in at $30 million, will increase the capacity of the high school from 1,500 students to 2,000, along with improving facilities and adding a fire containment sprinkler system to the old structure. The renovation work also included upgrades to lighting systems and new ceilings, in addition to new paint on the exterior.

The new high school features a compact and efficient design with two gyms, the cafeteria and an auditorium located at the center of the structure, as opposed to being held in separate facilities, like in many older schools. Mike Brady, CEO at Michael Brady Inc. and lead designer on this project, explained this format drastically decreased the surface area of the external walls, by at least 30 percent compared to a standard school, which significantly increases the energy efficiency of the facility.

Centralizing these functions also created a more coherent feeling for the entrance of the school, which features a large two-story common space with high ceilings and a railing on the second floor, allowing students to look down over the entire area or gather and socialize before and after class. This common area also connects directly to the gyms and cafeteria, giving the school an open, organized and centralized feel.

Students will get to explore the new facilities early and often, as the school has a unique lunch schedule, where all students eat at one time and can take their meals anywhere they want.

As Brady explained, “The students have an hour to participate in lunch and extracurricular activities or exercise or counseling or journalism groups throughout the school. It’s really kind of a wild place at lunch, but it really is fun. It’s just a really positive environment. It takes quite a bit more kitchen and serving because you have to feed 2,000 students all at once.”

One popular eating location will most likely be the new auditorium, which has a variety of use and seating options.

“We did the auditorium where the first part of the floor is flat so they can have banquets in there and dances in there. Then we’ve got stadium seating so it gives a lot of flexibility and different ways to have fun in that auditorium, more uses for it,” Brady explained.

“We still have a regular full stage up there. That gives them a chance if they want to come out and extend that stage really simply or, if you want, to have a theatre in the round.”

The CEO added that the lines of vision were extremely good for all of these potential uses and “you can also come in there and do wrestling or volleyball even.”

Bill Steverson, principal at the design firm and project architect for this job, explained that wrestling was a very big sport in the local area and the school accordingly contains a large wrestling room with enough space for two mats, meaning multiple training matches can occur at once. The room also contains space for bleachers, allowing competitions or demonstrations to be held there.

“There’s also a weight training room inside the building that can be used by all the athletes, but it’s right there adjacent to the wrestling room and all the other locker rooms. They’ve also got separate locker rooms for track and cross-country and a coaches office area,” Steverson added.

Classrooms at the new facility are 9,000 square feet in size and contain a full wall of storage, along with a smart board.

“We have what we call a teacher technology control center where she can sit and network everything from her desk,” Stevenson explained.

The control center was designed with flexibility in mind, allowing the school to change out the technology hooked up to it as equipment and teaching styles evolve over time. Steverson added that the hallways had wiring for Internet that classrooms could tie into, but the school would mostly be wireless, with groups of servers spread throughout the facility. He said several computer labs were also included in the structure, located next to specific classroom clusters, meaning there are individual labs for math, English and foreign language studies.

The school also includes an on-site nursery for teachers and other staff members with small children. The nursery is similar to the classroom spaces in size, but includes a small kitchenette and has a separate entranceway, which leads to a fenced-in play area.

The existing structure continues to be used as a high school during the ongoing construction project, which is approximately 60 percent complete at this time. The two campuses were separated by fencing to keep students out of the construction site.

Most of the renovation work on the existing structures is being handled during the summer. “We worked just furiously during one summer period getting the sprinkler systems in place in what areas we could,” Brady explained.

The second and final summer of renovation work will begin this year and the project will be completed in time for the next school year.

“I think classes start the first week of August in the 2013-2014 school year so the teachers should have all of July, because the middle school teachers will also have to relocate into the new middle school. So the high school teachers will have to move out to the new high school,” Steverson explained.

How Window Film Can Improve Energy Efficiency in Schools https://schoolconstructionnews.com/2012/12/19/how-window-film-can-improve-energy-efficiency-in-schools/ MARTINSVILLE, Va. — Schools are constantly weighing the options of “going green,” but many are confronted with the harsh funding barriers that prevent some districts from spending money on green construction projects (or any projects for that matter).

MARTINSVILLE, Va. — Schools are constantly weighing the options of “going green,” but many are confronted with the harsh funding barriers that prevent some districts from spending money on green construction projects (or any projects for that matter). However, an answer for some districts may be simple, according to the International Window Film Association (IWFA). The IWFA, based in Martinsville, Va. is a nonprofit trade association composed of window film dealers, distributors and manufacturers in the window film industry and have supported the use of window film in projects nationwide, including school facilities.

Darrell Smith, executive director of IWFA explained the benefits of using window film in renovations at schools, which include reduced energy costs, safety and security, overall cost savings and reduced time for installation.

The energy efficiency of window film has been proven to reduce energy costs, according to Smith. Smith also explained that 98 to 99 percent of UV rays are blocked from entering through glass windows if they are protected by window film.

“Another advantage of using window film is to combat heat loads, and balance out hot and cold spots in the building,” said Smith.

By using window film, it can regulate temperatures on opposite sides of the building, where temperatures may vary depending on the time of day. There is also the added benefit of receiving natural light in the building, while keeping indoor temperatures down. Some districts choose to use curtains to block out the sun’s glare and heat during the day, but this leads to classrooms using artificial lighting. With window film, classrooms are able to utilize natural lighting, while the tint of the window film helps to reflect solar heat gain from entering.

Smith recommended window film for almost every school district, but believes it is more beneficial during a renovation (compared to new construction, although it can be used for new construction to combat glare) in order to save time, money and the environment.

“Schools can extend the life of existing buildings by using window film,” he said. “Window film also helps to improve the energy efficiency of the building. I think it is important to consider window film before ripping out and putting in new windows. It’s a no brainer that window film is cost-effective and you can get the same energy control as new windows, as well as some other added benefits.”

Other benefits include safety and security, such as bomb blast window film products, “which have been tested and are listed in the General Services Administration bomb blast criteria,” said Smith. “If there is a bomb inside the building it protects the people inside and in close proximity outside from falling glass fragments caused by the windows.”

The chosen tint of the window film also helps with added security, as outsiders cannot always see indoors if specific window film is used.

Along with safety, window film is also efficient when it comes to installation as well as return on investment.

“Installation only takes one day [after school] and does not disrupt classes, so it is perfect for schools looking to renovate their windows but on a tight schedule or tight budget,” said Smith.

The cost of window film varies depending on which film is selected and the area in which the film will be used. However, Smith explained that the lower cost of film would range from approximately $4 to $6 per square-foot, while the higher cost of film would range from approximately $5 to $9 per square-foot.

Smith explained that window film has been popular since the late 1970s and increases in popularity every time there is an energy and/or financial crisis, where people look for cost-effective and energy-efficient ways to renovate properties.

Although IWFA does not supply or manufacturer window film, they do provide information on where to locate professional window film personnel, including suppliers, manufacturers, dealers and/or distributors.

YERINGTON, Nev. — Nevada’s fourth largest school district, Lyon County School District in Yerington, Nev., has entered into an Energy Savings Performance Contract that is expected to save the district $345,000 annually for 15 years.

The district signed the $3.6 million ESPC with Framingham, Mass.-based Ameresco, Inc., an energy efficiency company that has worked on renewable energy solutions for facilities throughout the country. The contract will focus on infrastructure upgrades to 19 schools and four administrative buildings that serve over 8,400 students.

There are a total of eight elementary schools, five middle schools, four high schools and one K-12 and the Western Nevada Regional Youth Center — an alternative school. All schools in the district will receive energy efficient upgrades as part of the contract.

“Lyon County School District is proud of the relationship it has developed with Ameresco. We have been extremely pleased with their professionalism, expertise and commitment to the district’s project,” said Keith Savage, Deputy Superintendent of Lyon County School District. “The bottom line is that Ameresco delivers what they say they will deliver.”

Energy efficiency measures scheduled for completion by October 2012 include lighting systems, vending machine controls, computer power management, trash compactors, demand controlled ventilation and programmable thermostats.

“As one of the largest school districts in Nevada, Lyon County School District is setting a powerful example for other districts and communities,” said B.N. Tripathi, Vice President of Ameresco. “We are pleased to partner with such a forward-looking school district. We worked to ensure that this project has both short and long term benefits by hiring local contractors and vendors to complete the project.”

The energy conservation measures will help reduce energy demand and consumption — and are expected to cut LCSD’s operations and maintenance costs by nearly $25,000 by retrofitting light installations district wide. The energy efficient upgrades also allow the district to save $77,000 in rebates from the local natural gas and electric utility companies.

The greenhouse gas reduction benefits of the LCSD upgrades include the avoidance of 1,928 standard tons of carbon dioxide per year. This reduction in carbon dioxide emissions is equivalent to powering 208 homes each year.

Lighting Controls Provide Green Benefits https://schoolconstructionnews.com/2011/05/21/intelligent-lighting-controls-provide-green-benefits/ It’s no secret that replacing existing lights with more energy-efficient lighting sources, such as LED, is one of the easiest ways to reduce energy use.
 
Lighting in commercial buildings can account for up to 40 percent of total energy cost, but what most people don’t realize is that making the lighting source efficient is only half the story — an even greater level of energy reduction can come from improving lighting control.Lighting Controls Provide Green Benefits appeared first on School Construction News.

]]> Its no secret that replacing existing lights with more energy-efficient lighting sources, such as LED, is one of the easiest ways to reduce energy use.
Lighting in commercial buildings can account for up to 40 percent of total energy cost, but what most people dont realize is that making the lighting source efficient is only half the story an even greater level of energy reduction can come from improving lighting control.
Lighting control systems, based on a variety of technologies, have been proven to reduce lighting energy consumption in commercial and industrial buildings by up to 70 percent. These solutions can automatically turn off lights when they are not needed, optimize light levels to suit worker needs, reduce overall demand for lighting energy, and provide facility managers with system-wide lighting management.
Although the core concepts behind lighting control arent new, a set of advanced wireless technologies are bringing them more mainstream, providing ways to expand capabilities to a wider set of customers. It’s easy to install so all a company needs are licensed electricians.

It is not just schools that have to think about being energy efficient through the use of these light sources. Businesses such as factories have to consider this too. As they use a lot of chemicals as they work, it is important for them, or anyone for that matter to consider the impact this can have on the environment. This is why they use equipment like a ceramic catalyst, to help lower thermal expansion. Everyone should be doing their part when it comes to helping to make this planet a better place to live in.

Advanced Lighting Controls
Todays advanced lighting control systems create a large-scale lighting network that delivers the correct amount of light, where you want it, when you want it. Lights can automatically switch or dim at set times or under set conditions; facilities managers can make changes to lighting when appropriate or to meet financial incentives; and users can have control over their own lighting levels to provide optimal working conditions.
Customers of lighting control systems often apply a set of lighting control strategies or applications, each of which uses a specific technology and method to control a subset of lighting usage. These strategies include occupancy sensing, daylighting, scheduling, task tuning and more.
Lighting control systems typically include some or all of the following:
On/off and dimming controls
Occupancy sensors to detect whether rooms are occupied
Photosensors to detect the current illumination levels provided by natural and/or artificial light
Scheduling that turns on, off, and dims luminaires at preset times
A centralized control system interface (such as a wall panel or computer software) to manage all of the above
A method of communication between the lighting equipment and control system
A method of measuring, displaying, and responding to lighting energy usage
Emerging applications
In older lighting designs, each group of luminaires and lighting devices was installed in a closed loop and a facility manager could only access the lighting by physically accessing each room. Some of todays lighting control systems change this equation by linking together the control of an entire building and even separate buildings to remotely manage and control light settings. This way, each light and device within a lighting control system can be individually addressable, creating a truly intelligent lighting network. This vastly improves ongoing management cost and complexity, and provides the capability for facility managers to reduce energy use in ways that were never before possible.
New areas of savings are also being created in advanced lighting control systems by making energy usage data readily available for facility managers. Better data often equals better savings, and as managers gain access to real-time and historical information about the usage of energy by light, room, zone and building, they have the information for more effective decision-making. Also, some lighting control systems can tie into utility demand management programs, allowing buildings to automatically reduce lighting use at peak times in order to gain financial incentives.
Further benefits of advanced applications can include tax incentives, enhanced compliance with LEED and other building codes, and interoperability with an ever-expanding network of in-building smart wireless devices, such as plugloads, blinds, thermostats and more.
Removing the Wires
Within these advanced systems, the introduction of innovative wireless controls is further reducing costs and complexity while easing implementation. Wireless lighting control systems utilize wireless technology (similar to the wireless networks you may use to access the Internet at work or home) to communicate commands between lighting devices sensors, switches, and the ballasts or LED drivers connected to lights. For more information on smart lighting, you may want to check out a detailed review of some of the hottest smart lighting products on the market today. This way, you can make the most informed decision possible on what lighting method works best in your home.
While traditional lighting control systems utilize a controller that is hard-wired to each device (often with miles of copper wiring), a wireless system uses a controller with an antenna that manages communications between devices. Facility managers and individual users can utilize a software interface to manage the system and change settings, which are then routed through a controller to the individual lights. The result is a flexible, scalable system that is easy to commission, especially in retrofit scenarios where existing building infrastructure often gets in the way of installing a new lighting control system.
Lighting Controls & Green Buildings
Lighting is one of the largest sources of energy use on the planet, and yet only about 7 percent of commercial buildings have installed advanced lighting controls. Although lighting control systems have been shown to provide tremendous benefits, many parts of the commercial building market have been hesitant to utilize these systems in anything but the most basic configurations. This is often due to cost and complexity due to labor, equipment and wiring, and the commissioning, management and upkeep of these systems.
The new generation of systems is eliminating these cost and complexity concerns and increasing system capabilities by removing the dedicated control wiring. Through the use of modern enterprise-class wireless networking technology, system-wide controls strategies can be implemented without significant upgrades or added infrastructure costs.
Concurrently, the smart grid and other building systems have embraced wireless technology and are beginning to reap the rewards. Removing the wires delivers on the promise of lighting control by providing even greater benefits, at a lower cost, and to a much broader set of potential customers.
While net-zero buildings are still a long way off in the United States, intelligent lighting control systems with wireless networking capabilities are readily paving the way in helping companies take simple steps to save money and make our buildings greener.

HOUSTON — As part of its energy efficiency incentive program, Centerpoint energy company recently awarded a Houston school district more than $93,000 for efforts to reduce its peak electricity demand.
 
Spring Independent School District received the check as a reward for the total estimated annual kilowatt-hour savings at 10 of its schools.
 
Gloria Marshall Elementary School, a newly built school opening in August 2011, was responsible for more than $64,000 of the reward. The school was designed by educational architecture and engineering firm SHW Group. 
 
Gloria Marshall will be the first in Houston to use geothermal heating and cooling, according to design firm officials, which is expected to save at least 25 percent in energy consumption over the current code.
 
The school was designed with south-facing classrooms to take advantage of natural light.
With sensors in each room, the building is designed to have lights off in the classroom 75 percent of the time. The facility also features a highly reflective white roof, an on-site wind turbine and 10 kilowatts of roof-mounted photovoltaic cells that will convert sunlight directly into electricity, according to officials.
 
Designed according to LEED Gold standards, the school has already received an Energy Star rating from the Environmental Protection Agency for its design.
 
In addition to designing the Gloria Marshall, SHW helped the district receive additional incentive funding through “smart, energy efficient decision-making and implementation, including upgrades to lighting, HVAC, roofing and other M&V (measurement and verification) projects,” according to officials from the firm.
 
The incentive program, called the Centerpoint SCORE program, is a voluntary and free program that pays incentives for energy efficiency measures that reduce peak electricity demand.

Study: LED Bulbs Pose Health Hazard https://schoolconstructionnews.com/2011/02/25/led-bulbs-pose-health-hazards/

The post Study: LED Bulbs Pose Health Hazard appeared first on School Construction News.

]]>

IRVINE, Calif. — A recent study published by University of California researchers found that LED light bulbs considered environmentally preferable to traditional light bulbs contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.

 
“LEDs are touted as the next generation of lighting. But as we try to find better products that do not deplete energy resources or contribute to global warming, we have to be vigilant about the toxicity hazards of those marketed as replacements,” said Oladele Ogunseitan, chair of UC Irvine’s Department of Population Health & Disease Prevention, who led the study.
 
By crunching, leaching and measuring the tiny multicolored lightbulbs sold on Christmas strands, traffic lights, and car headlights and break lights, Ogunseitan and fellow scientists from UCI and UC Davis found that low-intensity red lights contained up to eight times the amount of lead allowed under California law. In general, high-intensity, brighter bulbs had more contaminants than lower ones — white bulbs contained the least lead, but had high levels of nickel, the university released in a statement.
 
“We find the low-intensity red LEDs exhibit significant cancer and noncancer potentials due to the high content of arsenic and lead,” the team reported in the January 2011 issue of Environmental Science & Technology in regard to the holiday lights.
 
A study of larger LED systems such as household overhead room lighting or bedside lamps is currently undergoing peer-review and will be published later, but Ogunseitan said the patterns are more of the same.
 
The university states that lead, arsenic and many additional metals discovered in the bulbs or their related parts have been linked in hundreds of studies to different cancers, neurological damage, kidney disease, hypertension, skin rashes and other illnesses. The copper used in some LEDs also poses an ecological threat to fish, rivers and lakes.
 
While breaking a single light and breathing fumes would not automatically cause cancer, Ogunseitan said it could be a tipping point on top of chronic exposure to another carcinogen.
 
The study found that risks are present in all parts of the lights and at every stage during production, use and disposal, according to the statement. 
 
For the past ten years, Ogunseitan and his team have been researching ways to make electronic products less damaging on the environment and to human health during their use and disposal, funded in large part by the National Science Foundation.
 
About three years ago, the team broadened their scope of research to include alternative assessments for high volume products as part of a new Research and Education in Green Materials program.
 
“As the technology for electronics evolved from cathode ray tubes which had high amounts of lead to flat panel displays, we thought that we should anticipate the solid waste stream by researching the components of newer technologies,” Ogunseitan said. “Light-Emitting Diodes seemed to be the newest and latest components of such products.”
 
The research was also motivated by the fact that LEDs are used in many household appliances and consumer products, including products aimed at children like LED pacifiers and rubber ducks, he said.
 
Ogunseitan said there had been no previous studies on whether LEDs should be categorized as hazardous waste either at the federal or state levels.
 
Ogunseitan cautioned consumers, manufacturers and first responders to accident scenes to take care when handling the light bulbs.
 
When bulbs break at home, residents should sweep them up with a special broom while wearing gloves and a mask, and crews dispatched to clean up car crashes or broken traffic fixtures should don protective gear and handle the material as hazardous waste, he advised.
 
LEDs are not currently classified as toxic and are disposed of in regular landfills. Ogunseitan has forwarded the study results to California and federal health regulators, the university reports.
 
Ogunseitan cites LEDs as an example of the need to mandate product replacement testing. Although diodes are widely hailed as safer than compact fluorescent bulbs, which contain dangerous mercury, they weren’t properly tested for potential environmental health impacts before being marketed as the preferred alternative to inefficient incandescent bulbs, now being phased out under California law, he said.
 
California Assembly Bill 1879, which would have required advance testing of replacement products, was originally scheduled to go into effect on Jan. 1 but was opposed by industry groups, according to the university.
 
A less stringent version was substituted, and Gov. Arnold Schwarzenegger placed the law on hold days before he left office, according to the statement.
 
“I’m frustrated, but the work continues,” said Ogunseitan, a member of the state Department of Toxic Substances Control’s Green Ribbon Science Panel.
 
He added that makers of LEDs and other items could easily reduce chemical concentrations or redesign them with truly safer materials.
 
“Every day we don’t have a law that says you cannot replace an unsafe product with another unsafe product, we’re putting people’s lives at risk,” he said. “And it’s a preventable risk.”
 
“I am very passionate about energy efficiency, and I think LEDs are a step in the right direction, but we should be very careful not to add to the toxicity risks that are already almost overwhelming for people and the environment from consumer products disposal,” he said. “I hope that we still have time before the lighting bulb regulation takes effect, to encourage manufacturers of LEDs to use materials that will not put the burden on consumers to avoid toxic exposures or to figure out how to dispose of hazardous waste generated by LEDs.”
 
Ogunseitan said any potential replacement testing bills and regulations also have to recognize that public participation is essential, and that it is important to have national, uniform standards for energy savings, as well as in reducing toxic exposures to people and the environment.
 
The researcher said LEDs deserve particular attention because they are used in a wide variety of products not necessarily related to energy efficiency. These “novelty items” are more likely to have shorter life spans than household lighting fixtures and are more likely to be disposed of inappropriately, he said.
 
“This study brings unfortunate news to those of us working in the design industry who are caught between the competing demands of making environments as healthy and energy efficient as possible,” said Mark Donahue, vice president and design director of HKS Architects, a global architectural design firm that aims to make buildings as carbon-light as possible. “LED lighting has held out great promise as a low energy alternative to high-intensity discharge and fluorescent lighting, and the fact that they generate very little heat is an added benefit.”
 
Donahue said that while sustainable design has become more recognized, both the economic and environmental full life-cycle costs have come to assume a more important role in the discussion.
 
“I haven’t had the opportunity to examine the UC Irvine study first hand, but green practitioners are always concerned when the byproducts of manufacture and disposal of building materials produces toxics,” he said.  
 
He added that one of the major advantages of LEDs, even with potentially harmful substances, is that because of their long-lasting life spans, the volume of material that ends up being disposed of is reduced.
 
“My sincere hope is that manufacturers of LED bulbs can find a way to reduce or remove the toxic substances from their products, because there really isn’t anything on the horizon that offers the same kind of energy and operational benefits,” Donahue said.
 
 
AJ Rounds, founder of a LED light bulb manufacturing franchise, said that while he was aware of the tremendous amount of mercury in compact fluorescent bulbs, hearing about the hazardous substances in LEDs was new information.
 
Rounds recently liquidated the company, citing the industry’s volatility and high expenses, among others.
 
“(LEDs are) not ready for release, that’s still another year or two out,” he said. “There are some applications where it’s really good, but others where it’s just not there yet.”
 
His company sold a variety of LED lights, from indoor appliances to outdoor uses.
 
“I think LED is the future of light, it’s only be a matter of time before LED is in everything,” he said. “But the economy we’re in and the state of nation really thwarts progress because the public is focusing on other issues. Not going green, but trying to make it day to day.”

SANTA BARBARA, Calif. — As a result of a number of ongoing campus-wide projects, Santa Barbara City College reports reduced energy consumption has saved the school $650,000 over the past year.
 
The college has seen a reduction of energy use by 3.6 million kilowatt hours and 25,000 therms, school officials said.
 
“Through these projects, we are serving as an example to the community that conservation is a viable energy strategy,” said Julie Hendricks, SBCC director of facilities and campus development.
 
The campus-wide projects include photovoltaic panels atop carports on the school’s West Campus and new energy-efficient stadium lights at La Playa Stadium, which alone has saved the college more than $100,000. The photovoltaic arrays covers three rows of parking spaces in the parking lot.
 
The stadium lights were replaced after issues with the old system, which school officials say presented a good opportunity to make them more energy efficient.
 
The stadium lights are now automatic with security lights on from 5:45 a.m. to dawn and sunset to 10:15 p.m.  The game lights are only on when games and classes are in progress, which ensures less energy consumption.

Skylight Efficiency https://schoolconstructionnews.com/2010/05/14/skylight-efficiency/  
Cool roof technology is increasingly popular as more schools increase roof insulation to reduce HVAC capital expense and year-round operating cost.
 
While skylights are desirable for their ability to bring light into otherwise dark interiors, they also function as rooftop solar collectors and hinder the ability of cool roof technology to help reduce air conditioning operating costs.

Cool roof technology is increasingly popular as more schools increase roof insulation to reduce HVAC capital expense and year-round operating cost.
 
While skylights are desirable for their ability to bring light into otherwise dark interiors, they also function as rooftop solar collectors and hinder the ability of cool roof technology to help reduce air conditioning operating costs. If the daylighting benefit is to outweigh the negative impact on the overall energy performance of a cool roof, skylights need to maximize visible light transmission while minimizing solar heat gain.
 
Equally important is a skylight’s ability to insulate against heat transfer caused by both conduction and convection. The basic construction of typical dual-pane insulating glass — low-e coated glass and clear glass separated by a warm-edge spacer and filled with an inert gas to create an insulating cavity — does a good job of reducing both conductive and convective heat transfer in vertically-mounted windows. However, when this dual-pane (or single-cavity) insulating glass is mounted toward the horizontal, as in a typical skylight, it can lose up to 40 percent of its ability to insulate against convective heat transfer, a direct result of shortening the convective airflow paths. 
 
This means that in the evening and winter, more heat in a school building escapes through a sloped skylight than it does through a vertical window using comparable insulating glass. And during the day, more outdoor ambient heat passes into a property through the glass in a skylight than through similar glass in a vertical window.
 
Since the energy conservation performance of skylights is primarily a function of the glass, the best way to maximize the energy efficiency of a cool roof is to create a second insulating cavity to reduce convective heat transfer. Triple-pane insulating glass can accomplish this, but unfortunately, is often too heavy to safely mount overhead, particularly for larger skylights.
 
An ideal solution is suspended film insulating glass, in which one or more heat-reflective coated films are suspended within the glass unit to create multiple insulating cavities at no additional weight. Such lightweight glass maintains a high R value (resistance to heat flow); a low shading coefficient (amount of solar heat radiating through the glass); and high visible light transmission.
 
In addition, the suspended film practically eliminates ultraviolet radiation that can cause fading, and because the film is clear and colorless, it maintains visual clarity and normal color rendition.

Yurko

Amy Yurko is founder of Brain Spaces, a Chicago-based consulting firm that offers efficiency programming and planning services for schools. She is a scheduled speaker at the 2009 annual Council of Educational Facility Planners, International conference. Her workshop focuses on ways that schools with budget constraints can make the most of available space. She spoke with School Construction News in a phone interview.

Q: What are the key components of school utilization and efficiency?

A: There are several components that need to be addressed. The first one is capacity, which is determined in a couple of different ways, including how many students are enrolled in the school and how many students participate in each one of the programs.

Another key component is scheduling. One thing that we’ve found is when we look at the schedule, we can often find a scheduling strategy that helps to make the building more efficient.

For example, a series of classrooms might sit empty while the students are in gym class. If you back-schedule with foreign language or other classes, then that classroom could be used and not sitting empty. It might help with the facility crunch.

Q: In your experience, are most K-12 school districts underutilizing their schools?

A: No. That is actually a trick question. Most of my clients have utilizations higher than the national average for classrooms. But there are also a number of caveats and specifics that need to be considered when you’re doing those kinds of calculations.

For example, if I have five students taking advanced German, do those five students use a whole classroom, when actually that classroom was designed for 25 students? You are not really using that space wisely. If you have an office space that could easily hold five students, schedule a class there. Leave that bigger classroom open for another larger class.

Consider scheduling, and also the number of students, the size of the space, and whether it’s appropriately sized for that program and number of students.

Q: How do you develop a scheduling strategy that increases building efficiency?

A: We look at schedules, the overall enrollments, the individual course-type enrollments and all the spaces in the buildings to align the use of those spaces with the people and the programs of the school.

That usually causes a reshuffling of room assignments. They don’t necessarily need to be reshuffled every period, but it may mean that if we swap two teachers, it could make all the difference in how that program is offered and how those students can occupy those rooms.

When I go into this scope of work, I never know what I’m going to find. It could be that one of the recommendations is to put together a committee to study the building scheduling.

I worked with a small middle school in Illinois. When we shuffled the schedule, we were able to take the number of teachers who had to roam from classroom to classroom from 80 percent to 20 percent. Teacher roaming has a huge impact on teacher satisfaction and turnover rates.

Q: What level of involvement is required from a district to successfully implement these changes and sustain them?

A: There are different ways in which districts prefer it to happen, and we have to work within their parameters. You can have a range of involvement from the district level. Depending on the level of involvement, the data varies.

I prefer to engage the district staff on several levels. First, I like to meet with the district leadership — all the people who work at the district level — to make sure that every school has standards that are being followed.

Q: How do you start the process with a district?

A: We look at the overall district guidelines, the district-level curriculum, and big overarching goals. Then we meet with the site-based leadership — the principal, assistant principal, and perhaps the special-needs director and curriculum coordinators — to get schoolwide goals.

We walk the building, and I usually like to be walked through the building by either teachers or students, depending on the grade level. At a high school, the students will really tell you what’s working and what’s not.

In a lot of cases, you take multiple tours, hopefully with students, teachers and/or administrators, and finally with a building engineer or maintenance director, because they have their own idea of what works.

Q: How do you ensure a school implements your recommendations?

A: It’s always good to follow through. Once you work with school districts with this level of intensity, you can’t help but have friends at the end of it. There is constant interaction and ideas thrown back and forth. It’s almost never a quick fix. It often takes a phased approach because of the complexity.

Oftentimes, we will provide a series of recommendations for things that can be done immediately within a school or classroom, then things that can be phased in that might take a little more time, and then a third phase with recommendations that might be more long-term or immediately cost-prohibitive.

It seems like every district goes into the process with the same thinking of what they’re going to come out with, and it’s never the same.

Q: What are some immediate changes that districts can make to create more space?

A: I can’t tell you how many places I’ve gone where a storage room has a quarter-inch of dust on everything. A lot of space needs are just about weeding and throwing out. Get off-site storage if you can’t throw stuff out. There is a lot of clutter in classrooms. Less clutter can make a space feel bigger, and it actually is bigger when you take stuff out that you really don’t need every day.

One way to facilitate that — of course, nobody wants to throw away their stuff — is to reorganize or switch teachers to a different classroom because it means they have to pack up their stuff and move. When they’re packing up their things, they always find stuff they don’t need and throw it out.

The other strategy is to consider school enrollments across a district and try to align them with the capacity for each of those schools. That usually entails ability to transfer from one school to another across boundary lines or a shifting of boundary lines. You don’t always have to do it with a boundary line. You could do it with vouchers or volunteers to move.

Q: Would you say the majority of changes are organizational, not architectural?

A: You can do different levels of change. There are administrative and organizational changes, including room reassignments, which you could make tomorrow. You can also do architectural interventions.

Classrooms can be divided into two spaces to better accommodate small groups and free bigger classrooms for something else.

Q: How do most school districts feel about sharing classrooms and other teaching spaces?

A: A little sharing can go a really long way, but it’s tied to teacher preference. Some teachers want their own rooms because they feel it’s important. But if a school district can’t afford to do that, then they have to cut programs. We have very little control over that, but sometimes if we talk to the teachers and show them what would be possible if they shared more spaces, they will get behind it.

Q: Do you see an equal amount of new schools and older schools experience similar growing pains?

A: I often find that the older buildings, the 1880s- to 1920s-era schools, are very easy to adapt in terms of space. Then you have the schools from the 1930s through the 1970s. Those buildings are hell.

Q: Why is that?

A: They are more industrial, with classrooms going down the hall and nothing extra. They’re very linear, with no windows, and are just difficult architecturally.

In general, within the last 20 years or so, it seems as though there has been a new awareness of the ability of a school to flex for future unknown programs.

Still, every school has its maximum capacity. When a new school suddenly does not have enough room, it is more of a demographic error than an architectural one. If the demographic projections are way off, you are going to need a new school sooner than you thought, or you might have a school that sits empty.

It’s really important to get a quality demographic projection done when you’re embarking on any process that has to do with facilities.

Q: Have you worked with school districts dealing with under-enrollment? How do you address that issue?

A: Yes. Then it’s an issue of how to use the facility. We talk about outside entities that could come in and rent space, and sharing with a community college or another educational institution that could use the space. Partnerships are almost always a great option to explore.

Q: What trends have you observed in the last year?

A: One of the main trends is districts are generally becoming more skeptical that they will be able to enhance facilities in the near future. More districts are looking for ways to utilize their space.

One of the key challenges I’m seeing in space utilization is an increase in the extent of special programs and services. There are general education and special education components, and the services for those are being widely increased.

Another trend is a higher emphasis on hands-on learning, which at the high school level involves a career-tech component. Any kind of project-based, hands-on learning often requires a little bit more space than a regular classroom.

It’s pretty difficult to go into a regular classroom and add 200 square feet. We have to look at other creative ways to share space or reduce enrollment in a class in order to allow fewer students but more equipment.
