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.

Hello, I would just like to ask regarding how I should model the ventilation system of my baseline model. My project is a hotel building which uses chilled water as its main cooling medium.

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.
