CompAIR: The New Tool by Pharos for Comparing VOCs

November 18, 2015


One of the outcomes of building to the Passive House standard is superior air quality.  The combination of air-tight construction and mechanical ventilation ensures that fresh air is in constant supply.  However, with air-tight construction also comes the responsibility to prevent the introduction of materials that will emit harmful gases into a controlled space.  The emission of volatile organic compounds (VOCs) is a threat to indoor air quality in any construction — airtight or not. When indoor air quality is of concern- then building a Passive House, with 0.3 ach per hour by means of mechanical HRV is a good way to reduce VOCs to significantly lower levels than that of a building built only to code. However, reducing interior VOC should be reduced as far as possible in either case.

When specifying the materials that will be used in the construction or in the interior of a space, it is important to have accurate data concerning the chemicals that will off-gas. To aid in this process, Pharos has introduced a new feature in the Pharos Project called CompAIR that provides accurate and reliable comparisons of the chemical off-gassing from paints, coatings and similar products. CompAIR calculates the weight of all volatile substances released into the air during application and curing of a product. By inputting a few data points into the calculator, CompAIR shows how products stack up, side by side.
