Does your home become unbearable in hot weather? Increasingly a hot home is an overheating office too. During the pandemic, up to 30% of people in the UK were working from home compared with 5% in 2019. But it’s hard to work if you live somewhere that becomes an oven in hot weather.

A recent government report into climate risks warned that unless homes can be kept cool in summer and warm in winter, health and productivity will suffer. According to some forecasts, air conditioning alone could contribute to as much as a 0.5C increase in global warming by 2100.

The Passivhaus Trust works to promote buildings built to the Passivhaus standard, which means they are comfortable to live in while using very little energy for heating and cooling. In 2019, the Stirling Prize for architecture went to Goldsmith Street in Norwich, a social housing scheme incorporating Passivhaus principles. “Our existing housing stock is in many cases poorly prepared to deal with rising temperatures,” said the Passivhaus Trust’s John Palmer.

The government wants 300,000 new homes built every year, and Mr Palmer says they must be designed to cope with the heat without using energy consuming air–conditioning.
