Frequently asked questions
How does this course work?
How long do I have access to the materials?
Does this cover residential or commercial scale buildings?
The focus on the enclosure approaches and mechanical systems are for residences and small scale institutional.
There are several residential case studies of varying sizes, then one case study is a new 17,000 sf Living Building Challenge campus center, and another is a Deep Energy Retrofit of a 35,000 sf school.
