Dear All:- Our project have ventilation spaces only (No A/c spaces) so how we model these building in energy model As per LEED Missing manual we follow below things "Assign HVAC systems as per Ap

Dear All, In my project I am trying to reduce energy consumption, I am using LED lights, high efficient air cooled units (baseline is water cooled chillers). The building already is underground bu

This is a V4 doubt but I cant imagine anyone is monitoring the V4 forum so i decided that posting it here would be more effective. Does anyone know wether or not evaporator input power should be i

I am not sure that I am interpreting section G3.1.3.14 in the correct way.

Hello, I am wondering if it is allowed to add additional exhaust fans into the proposed model to extract more hot air from the zone and save more energy on cooling. Is this possible?

Based on ASHRAE 90.1, the chilled water pumping power must be 22 W/gpm and does not mentioned the effect of pumping head.

We are working on a project which is mixed use facility (6 storey/G+5) . The first & 2nd floor is used for office & remaining for residential.

Markus, thanks a lot for your answer. Another issue appeared to this Heating only system - Baseline modeling of DHW (Domestic Hot Water). The Proposed model is having a gas fired boiler to provide

Shall the mandatory efficiency of section 6.4 (Tables 6.8.1) be verified also for a chiller that works as backup system (the chilled water is provided in normal conditions by district cooling)? Be

Hi all, We are undertaking the energy modeling of an office building and the Baseline is using a System 7, climatic zone is 4a.
