VOCs (volatile organic compounds)
Also called: VOC · volatile organic compound · low-VOC · off-gassing
Chemicals that evaporate into the air from paints, glues, cleaning products, new furniture, flooring and some building materials.
What it means
Formaldehyde is one of the best-known VOCs. Levels are highest after renovations or when new materials go in, and in tight homes with too little ventilation. Choosing low-emission products, ventilating well during and after projects, and storing fuels and solvents outside the house reduce exposure.
Why it matters in an audit
Insulation, sealants and renovation products can release VOCs, so ventilation planning belongs in any upgrade plan.
