We are working with a "Dayroom" space that has the following requirements: 4 ACH of Outdoor Air and 4 ACH of Total Air.

The credit requests confirmation that the project has MERV 11 or higher filters (if project is in nonattainment area for PM2.5). Is this request mandatory in existing buildings as well?

Hi all, I am pretty clear about the definition of nonattainment area given in ASHRAE 62. This being said, how to identify nonattainment areas for projects outside of the US/Canada?

Hi,

Hi,

Hallo, In an office building located in Mexico City (a location with a high PM2.5 and ozone levels), the floors are served by AHU’s equipped with MERV 8 filters.

I am looking for clarification on the Zone Discharge Airflow (Vdz) and Zone Primary Airflow (Vpz) values under the multiple zone systems.

Dear All,

We are evaluating the possibility of certifying a high-rise residential building project that will be built in Portugal.

We are working on a 9-story residential project that is being certified v4 BD+C: New Construction.
