Green/sustainability is not a trend; it’s becoming lawgCalifornia Legislation Title 24 sets energy efficiency standardsGovernment agencies requiring LEED Certification Government agencies requiring LEED Certification Regulation Concerns

Green/sustainable design is here to stay
On the horizon: Federal Trade Commission guidelines on On the horizon: Federal Trade Commission guidelines on environmental claims. A flood of products labeled “sustainable,” “renewable” or just plain “green” has the FTC digging into enforcement issues with four actions taken this digging into enforcement issues, with four actions taken this past summer alone.
Firms will have t0 substantiate claims indicated what it is that Firms will have t0 substantiate claims, indicated what it is that makes one type of product more environmentally friendly than another. It won’t be enough to simply prove a product is made from recycled material or that raw materials used are renewable from recycled material or that raw materials used are renewable, for example. Chance are manufacturers will also have to clarify how that saves water, reduces carbon footprints or the like.

Provide an outstanding learning environmentg gFacilities must be durable Facilities must be easy to maintain Provide long‐term benefits to students, teachers and taxpayers
Prerequisites – common sense points Goals‐1. Improve learning environment2. Less costly to operate3. Conserve our natural resources
Green school n. a school building facility that creates a ghealthy environment that is conducive to learning while saving energy, resources and money.

EPA has an indoor air quality tool for schools

Fewer allergens fewer absences
Lighting is one of the most critical physical g gcharacteristics of the classroomA study conducted by Pacific Gas & Energy (C lif i ) f d h l i h l (California) found that classrooms with natural lighting scored 26% higher in reading and 20% higher in math in math Daylight in schools: improving student performance and health (ASES Conference, June 16, 2000)
Conventional WindowsUsable light under most conditions for side of class nearest windowsFrequent need to use at least half of the electric lightingFrequent need to use at least half of the electric lighting
More advanced day lighting designsDecreased dependence on electric lights, dependent on Decreased dependence on electric lights, dependent on the daylighting design, solar orientation and climate
Acoustics should be taken into consideration throughout the design process not when the project is completed problems arise

What is the more sustainable strategy?
Keeping an 8‐year old clunkerB i V lk ith Buying a new Volkswagen with a diesel engineBuying new Toyota Priusy g y
I always ask Prius people, “Your last care before the Prius, how long did you hold on to it?” It’s 1,000 gallons of fuel just making a car, shipping it, delivering it; the act of discarding it recycling it takes a lot of energy too delivering it; the act of discarding it, recycling it, takes a lot of energy, too. So maybe a better thing to do rather than buying a new Prius is keeping your car old car 8‐10 years. It’s probably the more sustainable strategy.
