Abstract

Forms the second part of a two-stage consultation proposing changes to Part L (Conservation of fuel and power) and Part F (Ventilation) of the Building Regulations. The first stage of the consultation concluded in January 2020 and related to the Future Homes Standard. The focus of this new consultation extends the intended requirements as the Future Buildings Standard, aiming for highly efficient non-domestic buildings making the most of low-carbon heat technology. The changes to the Building Regulations are due to be introduced from 2021 onwards, and the Future Buildings Standard in place from 2025. The options under consideration relate to improvements in energy modelling methodologies, and to standards of work on existing non-domestic buildings. Other areas for consideration look at mitigating overheating in new non-domestic buildings that are classed as residential. The changes will also bring about similar requirements in new domestic buildings for mitigating overheating, improving standards to work being carried out in existing homes. Final area of consideration relates to the Fabric Energy Efficiency Standard. This is the January 2021 draft Approved Document L1, and highlights the differences to existing requirements.
