PHOENIX, May 31, 2011 /PRNewswire/ -- Phoenix residents will return from the Memorial Day weekend to witness installation of the first "Cool Pavement" parking lot in central downtown Phoenix. This 90,000-square-foot temporary parking lot located between First, Second, Taylor and Polk Streets will now help cool the city this summer. The asphalt parking lot is "going green" literally, with Emerald Cities™ "Celadon Green" solar reflective permanent cool coating which reduces hot asphalt surface temperatures by at least 30°(F) on hot days, helps reduce C02 and in general helps to mitigate the effects of downtown urban heat island (UHI).

The project began on Wednesday, May 25th, with spray crews working at night for the very reason the project is being done, namely, Phoenix asphalt is hot at this time of year. Emerald Cities™ "Cool Pavement" is a state-of-the-art climate change product and its benefits are being introduced at the "Cool Pavement" event in Phoenix on June 10, 2010. This event is to provide public awareness of "Cool Pavement" as a cost-effective solution for cooling and beautifying hot black asphalt.
ASPHALT "GOING GREEN"
Asphalt parking lots are one of the most important assets of cities and property owners everywhere. But scientific studies have recently determined that "black" asphalt is a major contributing factor in the formation of urban heat because it absorbs and stores heat.
For example, summer heat in downtown Phoenix can reach temperatures of 115°-118°(F) with asphalt surfaces averaging 150°-170°(F). Heat is then re-released when the sun goes down causing the city to heat up again. Urban heat is a problem facing every city in the world, and is taking its toll on every facet of city life. In the fight against climate change, "Cool Pavement" is the future of asphalt for many of the following reasons:
- Businesses trying to meet urban sustainability standards
- Commercial businesses trying to reduce A/C consumption cost due to urban heat
- Apartment building owners resurfacing asphalt destroyed by urban heat
- Commercial Building owners trying to cut A/C consumption in urban heat
- Healthcare professionals treating more illness due to heat and pollution
- Shopping Malls losing valuable consumer sales due to summer urban heat
- Amusement parks losing attendance due to urban heat
- Children's health problems on hot inner city asphalt playgrounds
- Athletes struggling to train on hot inner city asphalt courts
- City governments looking for solutions to solve urban heat and energy waste
- Power companies working to forestall power outages due to urban heat
- General public's rising electric bills due to urban heat and wasted energy
- "Cool Pavement" protects asphalt from UV degradation and water intrusion
100 CITIES "COOL PAVEMENT" INITIATIVE
The US Environmental Protection Agency (EPA) coined the term "Cool Pavement" to describe coating materials for pavements that reduce surface heat and the effects of urban heat island. In 2008, US Secretary of Energy Steven Chu announced that "Changing surface colors in 100 of the world's largest cities could save the equivalent of 44 billion tons of carbon dioxide…about as much as global carbon emissions are expected to rise by over the next decade". Emerald Cities™ has spent two years in R&D to develop its proprietary product which incorporates the research of Lawrence Berkeley Labs, MIT, and the field work of Intelligent Concrete LLC working with Emerald Cities™ to perfect a coating which is a "solar reflective ultra-high performance nano-engineered thin concrete".
