Thank you Sean White, you rock!
I recommend all people who work in the field of building science and new energy to participate in this course.
I work in the solar industry as a PV Designer and this is a great resource to keep yourself up to date with the NEC code. I recommend 100% this curse.
Heatspring courses have broadened my understanding of the renewable energy industry and I would recommend them to anyone interested in the future of energy.
I appreciate these free videos as a new hire at ReVision Energy's South Porland, Maine branch.
