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.

Does anybody know if performing energy modeling using ComCheck satisfies the requirements for Whole Building Energy Simulation, or is something more extensive required?

If same Lighting Power Density (W/sf) was used in all zones during the design phase using Building Type Method, should we switch to space by space on its final stage?

Hi, I have a doubt on how to establish the heating setpoint for an HVAC system which has no heating system. In a specific project, I have only cooling system serving conditioned areas.

Hi, we are working on a residential project.

In the proposed design, we are using a water-to-water heat pump for the sole purpose of service water heating. Voltage and Amps are 460v and 140 RLA, respectively.
