Some Thoughts on Sustainable Building

Sustainable building isn’t just about what the products we use are made of. It’s also about how product choice affects waste and the number of trips to the jobsite.

Mike O’Brien, a Green Building Expert for the Office of Sustainable Development, informed us that the average house built in Portland creates 4 pounds of waste per square foot during construction. That includes concrete forms that have outlived their useful life and all the ends of wood framing that are cut off and thrown away.

Our steel framed walls are built with very little waste because each stud is formed using our Nuconsteel roll former to the exact length required. There is no waste except for the punched holes for wiring and plumbing, and that waste is collected and 100% of it is recycled. Also, by building all of the walls in the plant we save trips to the jobsite. Instead of taking 3 weeks to frame a house on site it can be done in a matter of a week. That saves 10 or 12 trips to the jobsite for the typical crew that probably each drives their own car every day. All of the interior and exterior walls are built in the plant and delivered the next day for installation.

This trailer holds enough steel to be recycled into framing for 3 homes.

Our steel studs are produced using 100% recycled steel provided by Nuconsteel. For a 2,000 square foot home we use the equivalent of 4 crushed cars for our framing.

The average 2,000 square foot house uses 11,000 to 13,000 board feet of lumber. That is about 8 of these truckloads per house or an acre of forestland.

It’s not just about recycling. It’s about the processes that our product choices allow that reduce the waste created in the first place that helps make our homes sustainable.

Not to mention that all of the products put together create an energy efficient, comfortable, super strong, safe home.
