Part one of this article mini-series explained how vulnerable people are likely to respond to the energy crisis this winter. But what will happen to occupant health when people cannot afford to turn the heat on, and how will low energy buildings fare?

While most people will feel the squeeze as a consequence of the energy crisis, for vulnerable people spikes in energy prices may be a matter of life and death. In a two-part mini-series of articles in this issue, Kate de Selincourt peers into the void to see how vulnerable people may respond to high energy prices, and what the impact will be for their living conditions and their health. 

Review finds that SAP is not fit for purpose, by Kate de Selincourt.

The Welsh government has issued a new standard for social housing that requires an embodied carbon assessment, favours timber-based offsite construction, and bans fossil fuel boilers.

A comparison between two pairs of households in Switzerland suggests that people do not reliably compensate for lack of mechanical ventilation with more window opening.

A new analysis of the exposure of London households to indoor pollutants highlights “systematic inequalities” in exposure, overwhelmingly driven by factors beyond the control of those people worst affected.

While the Irish government is delivering CO2 monitors to schools to help prevent the spread of Covid-19, and some European regions have mandated the use of such monitors in all buildings open to the public, the UK has yet to introduce such measures and has removed the requirement for mask-wearing in schools.

Radon is one of the most dangerous indoor air pollutants, yet there is little research on how it is affected by different forms of construction and ventilation. A new study, however, suggests that homes built to the passive house standard are significantly less at risk of radon build-up.

With governments across Europe looking for ways to jump start their economies following the early impact of Covid-19, attention is increasingly turning to deep retrofit. But while there is strong evidence that deep retrofit could play a major role, the devil will be in the detail – and the challenge of dramatically upscaling a nascent industry shouldn’t be underestimated.

A ground-breaking new passive house in Bristol makes superb use of an urban plot to create a bright and spacious home built from ecological materials that — thanks to its huge solar roof and Tesla battery pack — produces more energy than it uses, making it one of the first UK projects to meet the passive house ‘plus’ standard, while also blitzing the RIBA 2030 Climate Challenge’s targets for operational energy.
