Many regulations are changing in the drive for greater energy efficiency and more sustainable buildings. The combination of new Part L, the Code for Sustainable Homes, the European Performance of Buildings Directive, the Sustainable and Secure Buildings Act and Planning Policy Statement 22 will all have a substantial effect on buildings in the UK. PPS22 has really caused a stir because it enables local authorities to demand that a percentage of a building's energy be provided from on-site renewable energy sources. Since this provision has been available, about 70 local authorities require a 10% contribution from on-site renewables, one requires 15% and several are thought to be considering 20%.
