Fantastic Summary of articles on constructing a low-energy, pretty good, or passive solar home! We often send clients to read Martin's thoroughly researched and well-written articles. Seeing his primary articles all in one place is invaluable!
The Energy Nerd's Greatest Hits would make a thorough course for both builders and architects/designers as well as home owners who want to be intimately involved in the design and building process. I wonder if Fine Homebuilding and/or Green Building Advisor would see this as a worthwhile course to be developed and offered through energy conferences and/or webinars - something that bridged the gap between Energy Star and Passivhaus. And surely CEU continuing education credits could be had with AIA, USGBC, etc.
In any case, keep up the good work. Martin seems to write new articles faster than we can read and absorb them.
We live in an 85 m2 tract home that I retrofitted 21 years ago. I have monthly calculations and know the Energy Efficiency Index for each month and year. There is no one way to conserve, but it is always more cost effective to take advantage of the site and hold onto what you have. We rarely run our HVAC. The biggest problem is educating realtors and builders.
Oh my gosh, thank you SO MUCH for collecting all of these! And, I haven't read them all yet, but I'm assuming you wrote most of them, too. And, based on the title, probably all of them ;-) Thanks Martin!
