The Green Building Alliance, the City of Pittsburgh and other partners are seeking Downtown property-owners who'll turn off or dim their roof-top signage and other nonessential lighting for one hour this Saturday night as part of the international observance.
Last year, more than 7,000 cities in 153 countries participated in Earth Hour.
Property owners are asked to dim the lights between 8:30 and 9:30 p.m. A GBA photography team will be posted on Mount Washington to record what Downtown looks like on this opposite-of-Light Up Night.
The idea, of course, is to raise environmental awareness about the effect of energy usage on things like climate change. Who knows, maybe the effort will even make a few more stars visible.
If interested, sign up on GBA's website.
The project is also being sponsored by the Mayor's Office, Sustainable Pittsburgh and the GBA's Pittsburgh 2030 District, which has recruited Downtown property-owners to commit to reducing their energy use, water use and transportation emissions by 50 percent by 2030. So far, more than 100 buildings are participating.
