Most of the greenwashing we see falls into one of these nine types. Here are tips on how to spot them.

I am going to go out on a limb here, but I would bet that sometime in the last 24 hours you have received a marketing message centered around how "green," how "environmentally friendly," or (if it's really serious), how "sustainable... Read more

Our clothing is our second "skin" and our home's envelope is our third "skin." Each must be semi-permeable and able to breathe. This puts my philosophy of building at odds with much of the so-called "green" building movement, which relies heavily on non-breathing, non-natural and ecologically harmful plastic.

Everybody loves a high-tech innovation, and our windows are very high-tech, but have we reached a point where we don't need to push further?

June 4, 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?

In recent years, an increasing number of window manufacturers have been combining and refining the features... Read more

Before you peel that NFRC sticker off the window, check the numbers and ask whether you got the right window for your climate.

May 30, 2011

 

Have you ever found yourself picking a sticker off a building product or material from the store, and wondering, why did they put the sticker here? I have often had this thought with everything from stovepipe to plumbing fittings, but the classic example in the building world is probably windows.

The glass part of the window... Read more

It has been a great spring so far for spotting wildlife. A neighbor told me he was shooing a black bear away from his garbage the other day when he saw that he had also frightened off a moose that was also in the neighborhood. Perhaps the moose and bear are rehearsing for a new wildlife buddy movie?

I spotted a porcupine crossing the... Read more
