Saving money by “greening” buildings.
According to an article in Time (April 18, 2011), a lot of money can be saved by retro-fitting old buildings. I have written a few posts already about this, but this article gives some really good examples of the kind of money that can be saved from some relatively simple initiatives.

Some investment in lighting, heating and insulation can make a huge difference to costs and energy efficiency. For example, the Empire State building spent $13m in 2010 on a retrofit. The result is a 38% decrease in utility bills and a payback period of less than three years. Another example is a re-fit of a federal building in Cleveland, which saves $600,000 per annum. The city of Melbourne, Australia is also mentioned. The city’s Lord Mayor sums up well – “this is not some feel-good environmental initiative. It is a hard-headed economic business decision.
