Why Cooling Demands are Increasing?

A recent survey showed that 80% of Londoners said they suffered from overheating in their homes this summer. One in ten said their homes were uncomfortably hot most of the time. Temperature logging in homes shows that temperatures regularly exceeded generally accepted temperature thresholds.  This problem is going to get worse. Tighter Building Regulations have improved insulation – reducing energy bills and greenhouse gas emissions.  We also generally design homes to have good levels of daylight which makes them a more pleasant place to be.   More insulated homes with higher amounts of glazing mean it can be more difficult to keep homes cool.  To add to this the projections are that summer temperatures will increase significantly.
