Gil In areas where the air conditioning load is high, energy is conserved by limiting the outside air. Consequently, as in airplanes, the air can be mostly re-circulated. Bear in mind the number of sources of contaminants - carpets, paints, wallcoverings, furnishings, photocopiers, papers, cleaning chemicals, soil in potted plants, pest control products, the occupants of the building and the scented products they wear. The best strategy to improve the quality of the air is controlling the sources. This can be done in houses (you can replace carpets with hard flooring), but not in buildings. The quality of the air relies on the ventilation system. The biggest challenge is keeping the mechanical systems free of molds and bacteria.
