Optimising heat network design

Optimising heat pumps and electric boilers to minimise capital costs and customer bills will be essential to realising the government’s ambitious plans for heat networks. Max Fordham’s Adam Reeve looks at three routes to affordable heat, including storage, Grid balancing and hybrid heat sources

Cooling the suburbs: air-to-air heat pumps

John Greengrass MCIBSE specified reversible air-to-air heat pumps for his 1930s semi-detached house, to supplement his solar heating – but the cooling function is now proving its worth, writes Alex Smith

Redefining with retrofit: CIBSE’s Building Performance Champion

The University of Auckland’s B201 is one of the world’s most sustainable academic buildings. Andy Pearson explores how CIBSE’s 2026 Building Performance Champion used deep retrofit and building services engineering to transform the 1970s campus

Why proven heat pumps still struggle to scale

The successful adoption of heat pumps is affected by complexity, compatibility and user experience, according to UC Davis research. Tim Dwyer looks at how consumer uncertainty threatens the rollout of heat pumps into the mainstream

Setting the standard for social housing

Social housing retrofits can meet the upcoming UK Net Zero Carbon Buildings Standard, but the costs are high, says ECD Architects’ Loreana Padron, based on a 48-homes Cambridge City Council pilot delivered by the practice

Bridging the heat pump efficiency divide

Real-world analysis of domestic heat pump installations has identified underlying reasons for system underperformance. Alex Smith looks at the study paper’s recommendations, which the authors say could reduce household’s annual energy costs by 26%
