Did you know that direct and indirect emissions from buildings account for around 16% of the UK’s total greenhouse gas emissions? Emissions from buildings have reduced since 1990, but there’s still some way to go to reach net zero by 2050.
Heating and powering buildings currently accounts for 40% of the UK’s total energy usage. Reducing building energy demand through improved fabrics (insulation, double glazing, etc) is important, but this won’t be enough for homes to reach net zero emissions by 2050.
- New builds – The UK Government’s ambition is to have new homes produce 31% fewer carbon emissions from 2025 onwards, compared to current standards as it is significantly cheaper and easier to install energy efficiency measures and low carbon heating systems during home constructions than retrofitting them afterwards.
- Existing buildings – As many of the non-domestic buildings that will exist in 2050 have already been built, refurbishments will be essential to make significant carbon savings. The UK Government’s ambition is to deliver a 27% reduction in carbon emissions from 2025 onwards, on average per building compared to the existing standard.
