Oops... (corrected graphic below)

America's buildings are no small contributor to our environmental difficulties and energy use... but they're far from the biggest part of the problem. The enemy is us — the choices we make individually and as a society.

I have a little treat for Firefox and Internet Explorer 7 users: the BuildingGreen.com Search Plugin.

How can LEED hope to transform the building industry in an environmental mold if, to highlight the achievements of buildings, it relies on outmoded stores of value whose extraction and use does vast environmental and social harm: Silver, Gold and Platinum?

Common-sense steps can cool your home and reduce the need for air conditioning.

I'll admit it. I dread this hot, sticky weather. Give me a cool autumn-like breeze any day, even if it means wearing a sweater in July. But I also hate using a lot of energy, including electricity for air conditioning. So, what are our options for staying comfortable in the summer with little or no use of air conditioning?

Here are a few suggestions:
