Hi everyone,

I'm modeling an office building under LEED CS v2009. The scope of C&S includes a centralized cooling and heating system (air cooled chilers and heat pumps), ventilation equiment (DOAS) and 4 pipes to tenant spaces (fan-coils are out of the scope).

Since there are no efficiency requirements for fan-coils within Tenants Lease Agreemet, how should fan-coils be modeled:

1) Specific fan power

2) Part-load control (on/off, 3 speeds, EC motor)?

Thak you all in advance!
