DOE Zero Energy Homes aren’t just really efficient – they’re also designed and built using solid building science principles. Version 3 of the ENERGY STAR Certified Homes program, a prerequisite for every Zero Energy Ready Home, delivers three key systems that improve comfort, indoor air quality, and durability – a complete thermal enclosure system, a complete HVAC system, and a complete water management system. In this webinar, Dean Gamble of EPA will cover the building science basics that underly these key systems, as well as discuss the top three challenges of each system and how to overcome them.
