Chiller IPLV

NC-2009 EAp2:Minimum Energy Performance
posted by  Rathnashree Bharadwaj  on

Equipment Capacities for only one building pursue LEED

Hi, I have a District energy system (chillers, boilers, cooling towers, pumps) serves 3 buildings but only 1 pursues LEED, so my project doesn't use total capacities of those equipments.
