News on this has been trickling out for a little while now, but I wanted to put up an official information announcement here on LEEDuser: parking garages are specifically excluded from eligibility for LEED certification, as of a LEED Interpretation issued on May 9, 2011.

As I've said before, windows are a silent but very high-tech part of our buildings. The advances in glazing in the last 30 years have been phenomenal. Will windows keep getting better and better with no end in sight?

Recycling, and recycled content are good, right? Yes, but with some products you must look beyond that to decide if a product is truly green.

In a recent webcast on green building product certifications, I gave a counterintuitive example of greenwashing: a "recycled steel cabinet." Based on the number of questions I got about this, I realized this needed some more explaining.

We design a house from the inside out and engineer a house from the top down, but we build a house from the ground up. What are the most environmentally sensitive, durable materials?
