These result in a neg-five energy normalization credit per WSEC Table R406.2 Item 3. The total credits required-jeer Table R406.3 is four, not two. b. The project appears to be proposing the solar panel installation as an alternative to the energy credits in Table R4963. Solar panels are covered in Option 6.1. Additional documentation should be submitted substantiating the average annual production (AC kWh); the peak output during daylight summer hours should not be used. Note that the maximum credits allowed for this option is one per 12 kWh, and a maximum of three. c. Continuing with the previous comment, one or more additional energy credits are required.
