How to Mitigate Overheating on Noisy Sites
Posted on June 30th 2023
We have reviewed 3 mitigation measures to help developments in noisy locations comply with Part O 2021. Developments in noisy locations are now required to check overheating with windows closed at night. This is the most useful time to purge heat as it’s cooler. Many of our schemes are looking into new technologies such as ‘air tempering’ or ‘peak lopping’ …
DESNZ Extends Heat Network Capital Grants
Posted on June 29th 2023
The Department for Energy Security and Net Zero (DESNZ) have announced additional capital funding is to be allocated to the Green Heat Network Fund (GHNF), and extension of the scheme to 2028. The fund was set up in 2022 to support the development of new and existing low and zero-carbon heat networks. It has proved very popular, with the number …
Heat Pump Design Considerations
Posted on June 29th 2023
When designing individual air-source heat pump (ASHP) systems to maximise system efficiency and reliability, the following factors should be considered. External temperature: Unlike gas boilers, the heat output of ASHPs reduces as external temperatures decline. The standard external design temperature in London is -3oC. Mitigation this risk would require designing to a lower temperature (e.g, -7 °C). Designers should however …
