Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what steps he is taking to help ensure that new buildings include (a) insulation, (b) green roofs, (c) passive cooling and (d) other climate-related features through his Department's (i) planning policies and (ii) building regulations.

Through the Building Regulations, the Department sets minimum performance standards for new homes and buildings. In 2021, these standards were strengthened to ensure new homes and buildings are highly energy-efficient, with high-quality insulation and effective ventilation. These changes came into force in June 2022. A new overheating requirement was also introduced, requiring residential buildings to be designed to mitigate overheating, with passive cooling encouraged. We intend to introduce further changes to the Building Regulations through the Future Homes and Buildings Standards in the next few months. These new standards will ensure new homes and buildings are extremely energy-efficient and use low-carbon heating, such as heat pumps.

The National Planning Policy Framework makes clear that the planning system should take full account of all climate impacts and help to shape places in a way that minimises vulnerability and improves resilience to the effects of climate change through suitable adaptation measures, including through incorporating green infrastructure and sustainable drainage systems. It is also clear that opportunities to improve biodiversity in and around developments should be integrated as part of their design. The National Design Guide and National Model Design Code highlight the importance of conserving natural resources and measures that support energy efficiency and integrating green infrastructure into development incorporating features such as green roofs.
