BEIS Heat and Buildings Strategy Summary
Posted on October 27th 2021
The Heat in buildings strategy is short of new announcements for major developers but does aggregate policy work since 2016. It explains the current position, what needs to change and expected timelines (up to 2035) covering regulations, supporting programmes, and technological changes. A short thematic summary below provides an update of the central points: New Building Regulations Part L, still …
Air Quality Monitoring for Safe Indoor Working Spaces
Posted on October 27th 2021
CO2 monitoring in commercial spaces is a cost-effective way to manage spread of Covid-19 through optimising ventilation. Poorly ventilated spaces increase the risk of virus transmission. Yet, it can be difficult to manage effectively because air is invisible, making ventilation a less obvious mitigation measure. Monitoring indoor CO2 concentration is a useful proxy for understanding occupancy levels and ventilation rates, …
The Commercial Value of BREEAM Certification
Posted on October 27th 2021
Recent research shows that full BREEAM certification can lead to appreciable increases in rental values of commercial spaces. Tenants and lessors understand that sustainable buildings are more likely to be protected against future legislation changes, meet strong mandates coming from investors, and meet occupier demands to provide high quality working spaces for their employees. BREEAM aims to significantly reduce building …
Domestic Hot Water is getting cooler
Posted on September 14th 2021
CIBSE has recently published new guidance on domestic hot water temperatures for heat networks. The new document recommends the adoption of a 50°C target for the DHW generated at the hydraulic interface unit (HIU) outlet, with 45°C being reached at the kitchen tap within 45 seconds or less (notable exceptions exist, such as for vulnerable customers). The document has been …
Is enough being done to tackle overheating?
Posted on September 14th 2021
Since 2017, overheating has been recognised as a significant risk by the Climate Change Committee (CCC), but current regulations may not be doing enough to prevent it for the lifespan of buildings. Addressing this risk is fundamental to ensure resident health and satisfaction, especially since heatwaves in the UK are poised to be more frequent. The latest CCC report states …
‘Zero Carbon’ Development – Consider the Detail
Posted on September 14th 2021
The intention of a Zero Carbon development might seem simple enough, but its meaning is often open to broad interpretation by both housebuilders and planning authorities, with very real consequences for carbon reductions and project costs. By considering the methodology used, significant differences between one approach to a Zero Carbon development and another can be observed. Some of the key …
RIBA Award Winning Project
Posted on September 14th 2021
The Officers House in Royal Arsenal has just won the South East Regional Winner at the RIBA London Awards 2021. We supported Berkeley Homes East Thames in delivering the energy and sustainability strategy for the scheme, achieving a 40% reduction in carbon emissions. The heritage nature and listed status of the existing building posed a number of challenges around the …
Off-site District Heating connections: Key Considerations
Posted on July 29th 2021
Connection of housing development heat networks to external heat supplies is increasingly encouraged by local authorities. Successful delivery of this brings some opportunities as well as challenges. Tougher carbon targets and the fact that alternatives to gas-boilers and CHP are generally more costly (to build, as well as heat costs for residents) are two of the reasons why an incoming …
£280m now available via Green Heat Network Fund
Posted on July 29th 2021
Housing Developers are likely to have access to government funding for delivery of low carbon heat networks. In July 2021, the Government launched the Green Heat Network Fund (GHNF) Transition Scheme which aims to support commercialisation of low-carbon heat network projects, including planning requirements, legal costs, contract negotiations, site investigations and tariff structuring. The Transition Scheme supports both existing and …
