High-Performance Homes in the Mile-High City of Denver

High-Performance Homes in the Mile-High City of Denver

The Solar Decathlon is a competition where college teams combine beauty and technology to build high-performance houses powered by the sun. Held every other year, this international competition is the place where we become collectively smarter about high-performance solar homes - thanks to the best and brightest college students from around the world. 

At the University of Oklahoma College of Architecture, I first got the itch for sustainable, high-performance design. I was taught that architecture should be a machine for living in balance with nature, and a marriage between ecology and technology.

Although the Solar Decathlon began while I was in college, it was usually held in far-away Washington D.C. and it was just too far away to attend. This year the U.S. Department of Energy moved the Solar Decathlon in Denver, Colorado for the first time. I mentioned it once to my wife while feeding our toddler twins, and she must have seen something in my eye when I said that I would love to go and see the event. She later surprised me with airplane tickets and my heart leaped at the chance to go. 

Weatherization: Old Buildings Need to Tighten-up

Weatherization: Old Buildings Need to Tighten-up

Basic weatherization is a simple approach to improve comfort, energy efficiency, air quality, and the durability of an existing building. Weatherization is composed of two primary measures:  Air sealing and insulating. Both are important for improving energy efficiency, but pursuing airtightness should take precedent.
