Standards for rating a building's "greenness" have been established by several organizations, using point systems to rate energy use, water use, materials, design and more.  This home is seeking certification through three of the largest and most recognized green building protocols in the United States (one-of-a kind in Oklahoma):
  • U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED)
  • National Association of Home Builders' National Green Building Standard

  1. Awesome project! I live in the neighborhood and walked by it a few months back and it definitely caught my eye. I plan to come by for the open house to see the final result. I'm already jealous. =)

    I wanted to point out a little misinformation on the LED can lights however. The 100,000 hour rating means that it will take (on average) 100,000 hours before the LEDs are only generating 70% of the lumens they did fresh out of the box. They start losing brightness (not necessarily efficiency) from day one, not after a 100,000 hour delay. But you're right, they don't just burn out one day. Also, that 100k number is measured in a lab at room temperature with plenty of air circulation. In real world conditions the fixture will last about half of that rating. Most LED manufacturers have cut their ratings from ~100k to ~50k for this reason, and new testing standards have just come out which should eliminate these lofty claims. With all that said, I think they are a great choice from a maintenance standpoint, and mercury free to boot! Best of luck with your thesis!
