We’ve seen a ton of LEED Platinum homes on this site, but today’s home achieves something new. USGBC founder David Gottfried and his family recently finished the green renovation of their 1440 square foot Craftsman bungalow, a home that was originally built in 1915, and took it through the LEED for Homes certification process. In doing so, they received a total of 106.5 points (out of a total 136) and the noteworthy accomplishment of being the highest-scoring green home renovation since LEED-H launched earlier this year. The Platinum home is designed to be net-zero energy and utilizes technology such as solar photovoltaics and a solar- and hydronic-powered water heating system.
Last summer, it was the ceramic rod curtain wall. Now, it’s the lighting system. Various green aspects of the New York Times Building continue to make high profile news and it’s only been a year since the modern building opened. Here’s the deal: The Times Company installed Lutron’s Quantum solution, a total light management system that includes daylight, occupant, target set point, time clock, and emergency lighting controls. Although the building was originally designed to use approximately 1.28 watts per sf of lighting power, with the Lutron technology, it’s actually using only 0.38 watts per sf of lighting power — a 70% reduction in lighting use. That means, based on New York City electric rates, they’re saving ~$315,500 and preventing the emission of 1,250 metric tons of CO2 annually. These are some serious numbers. Here’s where they recognized the most in terms of lighting energy savings:
