A note about this course:

Marc Rosenbaum developed this course back in 2015 and hundreds of people have taken it. Around 2017 the demand for the course fell too low to justify Marc running additional instructor-led sessions.

So please be aware that while much of the course material is still relevant, it is no longer being updated. As a result we have lowered the price by more than half and made the course available as a ‘self serve’ course that is not supported by an instructor.

Learning Objectives:

• 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
