Passive Hybrid Downdraught Cooling

No Expiration


Passive Hybrid Downdraught Cooling (PHDC) is an energy efficient and ecological cooling system that is a real alternative to conventional air conditioning. This course is for people seeking a basic knowledge of PHDC. The course will review the physics behind downdraught cooling and explore its limitations as a solitary cooling system. We’ll look at various systems and strategies that can be used in conjunction with passive downdraught cooling to create a dependably comfortable indoor environment. Case studies cover how climate, site and local considerations impact design choices. Finally, we’ll discuss the LEED credits that this type of hybrid system can contribute.

Learning Objectives
