I’m confused about determining the amount of RECs a project must buy when the building uses electricity and some other form of energy, say natural gas. The ref guide on pg 207 is terribly unclear. It sounds like it is suggesting that we can’t just add up the total energy use in MBtus or KWh and then purchase RECs equivalent to two year’s worth based on whatever % total we’re targeting (e.g. 25% for 1 point). Instead, it sounds like we need to buy RECs for the electricity portion (based on its % contribution to the total) and something else, which the ref guide doesn’t really make clear, for the other forms of energy, in this case natural gas (based on its % contribution to the total). Is the latter the case? And is there a different name for these credits that represent renewable natural gas, propane, fuel oil, etc.?
