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.

Hi Marcus, I don't know what happened in the discussion "System fan power - Baseline". I can't post anymore... In my software, I give as an input the baseline design supply fan airflow rate.

Hi, I am trying to model a dining facility and am finding it difficult to determine the best way to include the energy associated with the kitchen equipment.

How do you apply Building Area Method (ASHRAE Table 9.5.1) to a higher education building that has five building area types? 1. School/University 2. Dining: Cafeteria/Fast Food 3. Office 4. Police/

We have a culinary school with many kitchen hood exhaust, I wonder if the hood exhaust fan can be considered as process energy instead of regulated fan energy. Thanks!
