The IAQVEC (Indoor Air Quality, Ventilation and Energy Conservation in Buildings) is an international scientific organisation whose mission is to provide technical support, guidance and technical publications to industry and research organizations for the optimization of indoor air quality, ventilation technology and energy conservation through annual conferences and workshops.

[2] The conferences cover a wide range of key research areas with the goal of simultaneously improving indoor environmental quality (IEQ) and energy efficiency enhancing wellbeing and sustainability.
