The invention provides a method and system for constructing a new space or
improving and existing space to achieve and maintain high air quality in
the interior of the space by limiting airborne allergens, VOCs,
particulates, and bio-aerosols therein. One method of the invention,
includes the steps of sampling the air quality of the indoor space,
removing suspected sources of pollutants, selecting replacement materials
having low-VOC off gassing, testing the air quality to ensure the space
meets a pre-determined base line air quality, and maintaining the air
quality of the indoor space at or below the pre-determined base line air
quality.
