Commercial and Multi-Family High-Rise Residential Buildings.
- Meet the requirements of ASHRAE 90.1.
- Design the building to achieve at least 30% energy consumption reduction from ASHRAE 90.1 baseline.
- If a 30% reduction is not LCCE, modify the design of the proposed building to achieve an energy consumption level at the highest level of energy efficiency that is LCCE.
- Determine energy consumption levels for both the ASHRAE Baseline Building and proposed building alternatives by using the Performance Rating Method found in appendix G of ASHRAE 90.1, except the formula for calculating the Performance Rating. Replace the formula in G1.2 with the following:
- Percentage improvement = 100 × ((Baseline building consumption − Receptacle and process loads) − (Proposed building consumption − Receptacle and process loads)) / (Baseline building consumption − Receptacle and process loads)
Low-Rise Residential Buildings.
- Meet the requirements of International Energy Conservation Code (IECC).
- Design the building to achieve at least 30% energy consumption reduction from the IECC baseline using the Simulated Performance Alternative found in Section 405 of the IECC.
- If a 30% reduction is not LCCE, modify the design of the proposed building \1\alternatives/1/ to achieve an energy consumption level at the highest level of energy efficiency that is LCCE.
Renovations.
- Renovation projects that replace everything above the foundation must either apply 2-3.1.1 or 2-3.1.2 as applicable.
- All other renovations choose one of the following options:
- Reduce measured building energy use by at least 30%, below FY 2003\4\, or earlier,/4/ energy use baseline.
- Reduce measured building energy use by at least 20% below FY 2015energy use baseline.
- Reduce modeled energy use (from all sources including renewable energy) by \4\30%/4/ compared to the ASHRAE 90.1 baseline building design for Commercial or Multi-Family High-Rise Residential Buildings, or the IECC baseline using the Simulated Performance Alternative found in Section 405 of the IECC for Low-Rise Residential buildings.
- If none of the reduction choices is life-cycle cost-effective, modify the design of the proposed building system(s) to achieve an energy consumption level at the highest level of energy efficiency that is life-cycle cost-effective.
Energy Efficient Products.
Per EISA 2007 Section 525, acquire products that are ENERGY STAR®-qualified or meet FEMP-designated efficiency requirements in all covered product categories, considering cost-effectiveness and availability. Link to EPA sites: http://www.energystar.gov/ or https://energy.gov/eere/femp/federal-energymanagement-program
Standby Powered Devices.
Per EISA 2007 Section 524, provide commercially available, off-the-shelf products that use no more than 1 watt in their standby mode.
