Part L of the Building Regulations
Through Part L (2010) the Government aims to reduce emissions from new non-domestic buildings by an average of 25% when compared against the 2006 standards. As the need for heat is the major energy demand in a building, it is vital that this area is addressed. This means that energy consumption has to be reduced as much as possible through reducing the heat lost by a building, making it more air tight and improving levels of insulation.
Low and zero carbon alternatives, such as heat pumps, can then be chosen to deliver renewable heat, whilst removing the need for direct fossil fuel use on site that typically results in higher direct emission levels.
