Installation of the winning block’s energy-efficiency upgrades have been ongoing since we celebrated at the block party in June – cool roof coatings were applied to all homes on the 1200 block of Wolf Street throughout the summer of 2010 and the insulation and air sealing installation is underway. The winter storms and snowfall Philadelphia has experienced so far in 2011 has slowed things down a bit, but we’re still on track to complete all installation by spring. Then the energy-savings measurement can begin! In the meantime, take a look at the view from one of the rooftops on the block. How ‘cool’ is that!
