Feature A11: Source Separation mandates that spaces with high pollution potential, like copy rooms, have their air exhausted directly outside to prevent indoor air quality deterioration. Copy rooms often house equipment like photocopiers and printers, which can emit volatile organic compounds (VOCs), particulate matter, and ozone, contributing to indoor air pollution. By ensuring that air from these spaces is expelled rather than recirculated, the strategy minimizes the spread of pollutants throughout the building, safeguarding occupant health and aligning with the WELL Standard's emphasis on optimal indoor air quality.
