AECOM director David Ross said:

“AECOM provided strategic and technical support to DLUHC in its development of the changes to Part L (conservation of fuel and power) and Part F (ventilation) of the Building Regulations and the introduction of Part O (overheating). Our work supported policy development in areas such as assessing the technical viability and the cost benefit of proposals.

“New buildings have been set an improved performance standard which will make them more energy efficient through better insulation, better performing windows and more efficient building services. The new regulations should also encourage the early adoption of low carbon heat by presenting a roadmap for its implementation in new buildings and they are also more favourable to low carbon heat sources such as heat pumps. Standards have also been raised to reduce energy use and carbon emissions when carrying out works to existing properties such as retrofitting or extending the building.

“These new regulations will have significant impact on the industry and the day-to-day decisions developers make about building design and specification. They should be seen as a stepping stone to the 2025 Future Homes and Buildings Standard and are an important milestone in the built environment sector’s journey to net zero emissions.”
