Advanced Energy Design Guide for K-12 School Buildings: Achieving Zero Energy

This guide provides user-friendly guidance for achieving a net zero energy K-12 school building. It includes a set of energy performance targets for all climate zones. Strategies on how to achieve these energy targets are provided throughout the guide and include setting measurable goals, hiring design teams committed to that goal, using energy simulation throughout the design and construction process, and being aware of how process decisions affect energy usage.

High-Performance HVAC

"Heating, ventilating, and air-conditioning (HVAC systems) account for 39% of the energy used in commercial buildings in the United States. Consequently, almost any business or government agency has the potential to realize significant savings by improving its control of HVAC operations and improving the efficiency of the system it uses."
