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.

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.

In environments where they will be covered by natural ventilation, how should I proceed in baseline model? For example, a factory or warehouse with the proposed natural ventilation, must be equal

Hi, Appendix G3.1.3.13 says "Minimum volume setpoints for VAV reheat boxes shall be 2.15 L/s·m2 of floor area served or the minimum ventilation rate, whichever is larger" When you have a HVAC sys

We’re working on a 20 stories building that is seeking LEED NC v3 certification. This building considers ASHRAE’s #8 HVAC baseline system: VAV w/ PFP boxes.

Our project is a multi-family residential project (8 stories) and we have modeled the baseline roof as a Residential, Insulation Above Deck U-Value per Table 5.5-1. We have received a LEED Review

We have a building that is using both natural gas and electricity for heating. Table EAp2-5 only seems to give me the option for one type of space heating energy source.
