I have a doubt about calculation of quantity of REC. I believe you can help me.
Using the Example 1 (in page 460 of v4) my project will consume 1,98 MWh per year. However, each REC is equivalent to 1 MWh. In my understanding, if I buy 2 REC I would use renewable energy for just 1 year.
In Reference Guide BD+C LEED v4, I found no explanation about how long I have to buy REC.
Only 1 year is enough? I just have to buy 2 REC to earn 2 points?
