Technical Feasibility Study for Zero Energy K-12 Schools
It is possible for K–12 new construction projects to achieve zero energy in all climate zones throughout the continental United States. This study includes:
• Energy use intensity (EUI) targets for all climate zones (Tables 23-26) to help users set goals for their zero energy school designs.
• A pathway for how to achieve these EUIs by climate zone, including values for the building envelope, fenestration, lighting systems (including electrical lights and daylighting), HVAC systems, building automation and controls, outdoor air treatment, and SWH.
• Case studies of actual K–12 school applications which demonstrate the business case and practicality of achieving zero energy schools.
This feasibility study was developed with input and guidance from a panel of industry experts. In many ways, this feasibility study is a simple interface to a complex analysis performed using EnergyPlus energy modeling. The combination of strategies contained in a single table should help facilitate increased energy efficiency in new buildings.
