Start by reducing the building’s energy load. The smaller the load, the less renewable energy you have to generate to meet the credit thresholds, which saves money and might expand the options you can use. For example, a 100-MMBtu/year building needs to produce 1 MMBtu/yr to reach the 1% credit threshold, while an 80-MMBtu/year building needs only 0.8 MMBtu/year.
