Cost/Benefit Analysis for Cool Roofs

We’re doing a remodeling project which includes installing a new roof. Here in California, we get a lot of sun, so the impact of solar irradiance on solar heat gain is a major concern — either for A/C costs (and thus peak summer energy loads) or on comfort (for those of us who don’t have A/C). Thus, I’ve been looking into solar reflectivity and what has been called the “cool roofs“ movement. There is the Cool Roof Rating Council, “created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance (radiative properties) of roofing products and to disseminate the information to all interested parties.”

Retrofitting Buildings will Create Green Jobs

Retrofitting 50 million buildings in the United States, about 40 percent of the building stock, by 2020 to make them energy efficient would create 625,000 permanent jobs, John Podesta, CEO of the Center for American Progress, told CNBC. “There’s probably a $500 billion investment that’s needed, but the vast majority has to come from the private sector,” Podesta added. “The government has a role to play in orienting policy toward getting the financing right.”

Princeton Review Rolls Out List of The Greenest Colleges

The Princeton Review, today released its second annual Green Ratings of colleges. In this measure of how environmentally friendly the institutions are on a scale of 60 to 99, the company tallied its Green Ratings for 697 institutions based on data it collected from the colleges in 2008-09 concerning their environmentally related policies, practices, and academic offerings. The Princeton Review also named 15 colleges to its “2010 Green Rating Honor Roll” – a list that salutes the institutions that received the highest possible score – 99 – in this year’s rating tallies.
