Dear all,
we’re currently involved in the LEED v4 Core & Shell certification of a new office building. This building will have a central HVAC system serving both common areas and tenanted spaces, that includes central AHUs providing ventilation and chillers/heat-pumps providing chilled water and hot water. Insided the tenant spaces, future occupants will have to install their own fan-coils at the time of the fit-out.
As the tenant fan-coils will not be installed in the Core & Shell scope of works, for purposes of energy simulation these equipment shall be considered with efficiency levels similar to baseline. However, the baseline system for this building does not have fan-coils (HVAC system type 8 – AHUs + FPBs). In this case, we are using the specific fan power considered in fan-powered boxes (0,74 W/(l/s)) to model the fan-coils fan power in proposed building. Do you validate this approach?
