Water: The Backseat Driver

Posted on May 6, 2010 by Peter Yost in Water Efficiency

When we talk about the environment and environmentally responsible building, it’s almost always energy that takes the spotlight, with water pretty far down the list. But it’s not hard to see just how much of a back seat driver water can be:

We don’t have any substitutes for clean water and we use a ton of it every day. Actually, more like a ton and a half; the typical US household uses 400 gallons of water a day and that’s about 3200 pounds! (Source: EPA WaterSense)

Paint Peeling in Sheets: Why?

Posted on May 5, 2010 by Daniel Morrison in Green Building Blog

This house is down the road from mine. The paint job was new a couple of years ago. Before that the paint was in pretty good shape on all walls of the houses except this one: this wall looked like it does now. I suspected then that there was some sort of moisture problem going on. After they re-painted, and the wall re-peeled so quickly (within six months), I was sure that it wasn't poor prep or cheap primer.

This is the north side of the house (sunlight is visible because the sun is setting).

Using a Roof for Rainwater Harvesting

Posted on May 3, 2010 by Rob Wotzak in Water Efficiency

The coastal community of Small Point shuts down its water supply in winter, which forced Laura Sewall to find an alternative source of water. A well was one option, but the high mineral content in local groundwater would have required treatment. More than that, Laura did not want to interfere with the area’s delicate hydrological balance.
