602.1.1 Zepi
JUMP TO FULL CODE CHAPTER
Performance-based designs shall demonstrate a zEPI of not more than 51 as determined in accordance with Equation 6-1 for energy use reduction and shall demonstrate a CO2e emissions reduction in accordance with Section 602.2 and Equation 6-2 for CO2e.
| zEPI = 57 × (EUIp/EUI) | (Equation 6-1) |
where:
| EUIp | = | the proposed energy use index in source kBtu/sf-y for the proposed design of the building and its site calculated in accordance with Section 602.1.2. |
| EUI | = | the base annual energy use index in source kBtu/sf-y for a baseline building and its site calculated in accordance with Section 602.1.2. |
