Interesting article from 321energy called, "Constructing a Foundation for 'Net-Zero' Buildings". A bit of an introduction to what is possible today in the field of building design. The goal is to construct homes and buildings that "use zero net energy" and are "carbon neutral", having found some ways to offset their carbon emissions.
Interesting. The "carbon neutral" jargon seems to be a point of contention from what I've found off the cuff. Here are two points of view on how mitigating emissions might work:
How to become a carbon neutral organisation.
Why 'Carbon Neutral' May Mean Nothing at All.
In any case, I do find the efforts towards "green building" intriguing and exciting.
