Hi, I am working on a LEED CI project in which HVAC equipments (serving tenant space) are not being replaced ( 5 RTU units), one of the RTU unit is very old and does not qualify Efficiency requirements of Table 6.8.1A. Based on ID#10134, I am understanding that all these 5 units still need to qualify table 6.8.1A and "New Building Institute's Advanced Buildings Core performance" requirements for Option 1(equipment efficiency - 5 points). Is this correct? Can I consider Option -2 to prove 15 % savings?
