Learn how to incorporate transformative energy upgrades in existing residential and commercial buildings up to 45,000 square feet.

Expect to learn:

• How to assess if a house is a good candidate for a DER

• How energy is used in most houses, and how DERs change that

• Typical deficiencies of existing homes and how a DER addresses them

• Heat flow, moisture flow, vapor retarders, and how to perform a simple heat loss calculation

• Building blocks of a DER—air tightening, foundations, walls, windows, roofs—and the range of approaches that have been successful

• Heating, cooling, ventilation, and domestic hot water technologies

• Case studies of successful DERs

Forget the theory. This course will fundamentally change the way you approach retrofit projects, while you earn credits and build a network. Your practice will never be the same.
