Philadelphia is out to become America's greenest
city. RetroFIT PHILLY is part of the plan to lead the nation's cities
in "greenness".
"... Greenworks Philadelphia goal is to retrofit 15 percent of the city's row home roofs, and the 'Coolest Block' contest is jumpstarting this effort," said Philadelphia Mayor Michael A. Nutter...."
" ... White cool roofs, ... bounce off solar energy to prevent it from being absorbed into the roof and house in the summer. ... they reduce the amount of energy needed to cool the living space and bring the cost of cooling a home down by as much as 20 percent."
" ... cool roofs are a proven way to combat urban heat island effect. The roof's exterior is 50 – 80 degrees cooler on hot summer days, helping to lower high temperatures and improve air quality. ..."
