Hello,

We are working on a project where the ozone levels exceed the most recent three year average, so we must include air-cleaning devices for ozone.

Hello,

Dear Everyone,

I have a question regarding to Monitor carbon dioxide (CO2) concentrations within each thermal zone. 

I am working in a hotel project where open fireplaces are being considered.

We are working on a residential project that is being certified v4 BD+C (not midrise).

We are working on a residential building where split AC units are provided in every room for each unit with no mechanical ventilation.

In multi-family residential units, can a VTAC unit provide mechanical ventilation to meet 62.1-2010?

We are working on a residential project (5-Story) that is being certified v4 BD+C. The dwelling units are naturally ventilated.
