"Each year K–12 schools spend more than $8 billion on energy — more than they spend on computers and textbooks combined. Too commonly overlooked is the opportunity to cost-effectively improve our nation’s schools and enhance student performance by tackling the performance of the very buildings in which children, faculty and staff spend more than eight hours each day."

Describes a variety of strategies for achieving low EUI for the ZE-ready Pell School in Rhode Island.
Despite the humid climate and lack of financial incentives, the American South is a hotbed of zero energy school construction.
"Effective use of daylight is essential in achieving a sustainable building design. The size of a glazed window is proportional to the level of daylight and depends on the proper integration of both window area and glass properties. Improperly designed windows could not only lead to poor illumination in building interiors, but may also cause fatigue, depression, and inefficient energy usage."
The study analyzed the variation of annual heating energy demand, annual cooling energy demand, and the annual total energy consumption in different conditions, including different orientations, patterns of utilization of air conditioning system, window-wall ratio, and types of windows. The results show that the total energy consumption increased when the window-wall ratio is also increased.
"Plug loads—such as computers and copiers—constitute one of the top three electricity end uses, after lighting and cooling."
Commercial mortgages currently do not fully account for energy factors in underwriting, valuation and asset management, particularly as it relates to the impact of energy costs on net operating income. As a consequence, energy efficiency is not properly valued and energy risks are not properly assessed and mitigated. Commercial mortgages are a large lever and could be a significant channel for scaling energy efficiency investments.
"Vast areas of exterior glazing have a greater impact on energy consumption than any other decision in the design of residential high-rises."
"When designers of the first net zero energy school in the U.S. considered how they would approach the lighting design differently using today’s LED technology, the results extended far beyond just switching out the lightbulbs. The hypothetical redesign of Richardsville (Ky.) Elementary classrooms involves rethinking the daylighting design based on the evolution of LED lighting and the cheaper cost of photovoltaics (PV)."
