We've had a designer tell us that built-in furniture and case work (like a fan-coil unit enclosure) can be deducted from the square footage of a room when calculating the window opening requirement

Hello; Out BAS does not measure air flow (CFM), but, it does measure Return Air and OA C02 values. Can this PreReq be met using CO2 measurement (demand ventilation) rather than CFM?

In our building we have two main AHU that supply 26 AHU (one for each floor of the building) and then we have VAVs for each zone in each floor. Do I need to perform measurements just in the two ma

We are using the 62MZ Calculator spreadsheet for an office building. The HVAC system does not utilize VAV boxes or any kind of terminal unit. Rather, it just feeds directly into each space.

Has anyone had experience documenting IEQp1 in the following situation?: I recently visited a facility that has one outdoor air intake for multiple AHUS.

ASHRAE specifies that the Ventilation Rate Procedure or the IAQ Procedure can be used to ensure that mechanical ventilation systems meet ventilation requirements in ASHRAE 62.1 (Section 6.1).

Hello All, I have a building where we are performing calcs on a select number of assumed potential critical zones as opposed to every zone.

I noticed that the LEED EBOM form does not have the same compliance path as LEED-NC, which allows you to document that your building complies with local code that is more stringent than ASHRAE 62.1

Our EBOM 2009 project (registered in late 2011 or early 2012) Score Card indicates that for IEQp1 we are to use the v4 form.
