We are working on a residential building that has common areas which are conditioned with split system heat pumps and heat recovery ventilators for fresh air.

Hello, Please let me know where I can find definitions for the following. a. Mechanically ventilated spaces b. Naturally ventilated c. Mechanically conditioned e.

Hi everyone! I have a project that the system works with outside air demand according to the CO2 sensor.

Hi everyone, We have a residential project which has around 600 rooms naturally ventilated. I've prepared an excel sheet to demonstrate compliance with natural ventilation requirements.

Hi, my project has PAU to supply OA through VAVs to AHUs, which then supply air to office spaces. This PAU also supplies OA through CAVs to lift lobbies and FCUs recirculate the air there.

we have a new addition added to an existing facility.

I have project with a dedicated outside air system that introduces air directly to the spaces on all levels (i.e. neutral air). The project has more than 100 VRF units.

We have a mechanical ventilation system that continuously supplies OA air into each apartment. Each apartment has a fan coil unit that conditions the apartment.

We have a project that is predominantly a parking garage structure.

We are pursuing for Fresh Air calculations for a Building with Natural Ventilation, as per the ASHRAE 62.1-2007 requirement, stated under the IEQ Prerequisite 1 – Minimum Indoor Air Quality Perform
