Research finds link between energy efficient homes and asthma

The research, in collaboration with Coastline Housing, assessed data from the residents of 700 properties in Cornwall. It found that a failure by residents to heat and ventilate retrofitted properties could lead to more people developing the condition.

It also found that people living in more energy efficient homes had a greater risk of asthma, and that the presence of mould doubled this risk.

This study is the first time scientists have been able to combine detailed asset management data with information about occupant behaviour and health, to assess the factors likely to contribute to asthma. It aims to highlight the need for changes in the behaviour of residents benefitting from energy efficiency schemes in their home.

Mark England, head of technical services at Coastline Housing, said: ‘Energy efficiency measures are vital to help keep costs low and reduce the environmental impact of heating our homes. This research has given us an invaluable insight into how the behaviour of people living in fuel efficient homes can affect health. As a result, we’re working to provide better information to customers on how to manage their indoor environment, including potential training of volunteer sustainability champions.’

The study pointed to other possible factors which can affect health in homes with high humidity, such as house dust mites and bacteria.
