In a manufacturing facility I worked at last summer we had a company paint the roof white. It was previously black and attracted much more heat. We noticed a material change in the temperature in the building after painting it white and could reduce our air conditing usage. A simple payback analysis will allow your firm to calculate how long it will take to recoup the initial cost of painting the roof white with savings in reduced electricity consumption.

In this aspect, wouldn't blocking the windows with some kind of white paper or blinds make things cooler, by eliminating the greenhouse effect?

You would have to weight that against possibly increased use of artificial lighting, but it might work.

Brilliant, thanks. These are exactly the sort of simple ideas I am after.

No problem. I'm sure the reduced temperature would be much for valuable to a data center than our facility as well. Goodluck!
