My building has four floors, and 4th flr is left empty for future use.

Hello, I'm working in the simulation of a building which has many HVAC zones defined so that should be modeled each ones as a separated thermical block but the zones of proposed building complies t

We have a project that consists of both residential and non residential units. Per 90.1 2007G3.1.1 exception a. we need to use two HVAC system types for residential and non-residential separately.

To comply with California codes we had to show compliance with Title 24-2013. This required us to use the proprietary program Energy Pro 6.

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.
