Home energy improvements

About a third of household greenhouse gas emissions come from our electricity use and heating. It is likely to be more for those with larger homes.

Insulate as much as you can to make your home warmer and to save on energy bills. Consider a whole house approach to achieve the best results. When you update your heating, the best option is likely to be a heat pump.

To achieve a zero carbon future, high standards for new buildings and for the retrofit of existing homes need to reduce energy demand for heating by around 50% (Zero Carbon Britain 2019, p. 40). LETI Energy Use Intensity targets aim to achieve a 60-80% reduction in total energy consumption.

LETI Climate Emergency Guides – Guides to achieve net zero for new builds and existing housing have been prepared by construction industry professionals representing a wide range of groups. 

NZC Toolkit 2

Net Zero Toolkit – A detailed guide to the design and construction of net zero homes, both new build and retrofit of existing homes, which is based on the LETI targets. Also includes some guidance for schools, offices, hotels and light industrial buildings.

LETI Targets

The LETI toolkit provides clear guidance on what you should do when building or retrofitting to be Net Zero carbon. It also summarises some things not to do, including:

  • Don’t be misled or distracted by technologies and environmental schemes that do not achieve the desired outcome.

  • Avoid business as usual and follow the emerging consensus on how to achieve Net Zero operational carbon. Many traditional ways of heating and ventilating homes are not aligned with net zero.

  • Do not forget about the risk of moisture and condensation from applying insulation and thermal bridges. Specialist advise should be sought to avoid these risks.
