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.

Hello, I am working on a project outside US and I am wondering how to approach the mandatory provision below. 6.4.1.5.1 Mechanical Equipment.

Common sense tells me they are not interested in by the second peak energy demands for each end user...so to ask the stupid question: Which average value should I output here...hourly average annua

Dear all, We are trying to calculate the IT & electricial energy consumption of a data center, using the Minimum Energy Performance Data Center Calculator.

Hi All, I am modelling a VRF system using ApacheHVAC in IES. But have no idea which prototype to choose.

Hello Everyone, we are certifing a new construction building in Germany. We have a question regarding the use of ACP and EAP2.

Hi all, Modelling DCV has been discussed many times in this forum. I gone through and understand quite a bit. I am listing my understanding along with some quires.

the project primary HVAC system is VRF+DOAS. there is one work shop space that have no indoor VRF unit but outdoor air intake through DOAS. DOAS is not intended for conditioning space.

Hi, I am not sure whether to class mechanical rooms which are free cooled by outside air as "conditioned" for the purpose of the baseline (so the baseline would be on system 5 in this example).
