Excellent look at what you can do with an existing house in a cold climate. Lots of detail to ponder.

by Linda Spier, Homemaker 10/13/2020

I love Mark's attention to detail, and even though this was a brief overview of a DE retrofit, he gave me confidence that I am in good training hands, for instance, in mentioning the flashing and critter guard details at the bottom of the exterior-mounted trusses. Thank you, Heatspring, for making this a freebie.

Case study demonstration was so good with hand drawing for easier understanding. Good Job, provide much more similar case study if possible in future.

This is a great quick overview of a deep energy retrofit. It gave me some ideas to research.

Informative story about a growing N. American need.

by Robert Lutey 11/17/2015

Marc touches upon most of the important considerations in this short case study and is engaging in the process. He left me, a novice in energy efficient building, wanting to continue my education for personal and professional reasons.

by Richard Meza 11/03/2015

enjoyable

by Michael Butts 10/16/2015

This course is helping me with my degree in Applied Design Sciences and my future career in sustainable design. You have to see applications applied so you can understand how things work and the steps to completion and this series of videos showed additional information that I was not aware of like external insulating and solar and geothermal panel location and the differences but most importantly the almost 0 carbon foot print obtainable. The most interesting new product was the Wood Pulp Bricks that you can burn and how you can calculate the usage more accurately but using something that is measured in weight and burns efficiently.
