More evidence of adoption of window film at European educational institutions.  An excerpt from the article.

Many believe that closing blinds is a solution – but this does not stop the direct heat from entering the building – it just slows down the time it takes to permeate around. The educational sector contributes approximately 15% of the carbon emissions from the public sector as a whole, which is one reason why Ed Balls appointed a Task Force to look into it. With increasingly hot summers it has become apparent that cooling is a major contributor to carbon emissions and most people have been slow to recognise just how much air conditioning, powered by fossil fuel driven energy, is contributing to our carbon footprint.

The idea of keeping the suns’ heat out of the building therefore makes financial as well as environmental sense and some studies show that solar control window film pays for itself in less than five years.
