The LEED Green Building Rating System places significant emphasis on natural ventilation. LEED has two prerequisites and two environmental quality (EQ) credits related to ventilation for indoor air quality to which natural ventilation can provide a positive contribution. The related LEED prerequisites include EQp1 and EQp2, while the associated credits are EQc2 and EQc6.2. Natural ventilation may also contribute to reduced HVAC energy use, achieving points under LEED Energy and Atmosphere Credit 1. Additionally, the Collaborative for High Performance Schools (CHPS) rating program for K-12 schools gives credit for natural ventilation.
