The implications of overheating when making energy efficient home improvements

Improving your home to make it more energy efficient under schemes such as the Green Deal, has numerous benefits in terms of saving on fuel bills and of course protecting the environment. 

In 2011, its reported that there were 4.5 million households in the UK in fuel poverty and with cold homes being a much bigger problem today than warm ones; introducing energy efficiency measures to reduce winter fuel bills, under schemes such as the Green Deal, seems a sensible solution to help combat fuel poverty.

The latest climate change projections, however, suggest that Britain will see warmer summers and an increased likelihood of heat waves. For this reason there is concern that some of measures suggested to make homes more energy efficient, could increase the risk of overheating and poor indoor air quality.

Research undertaken by the Adaptation and Resilience in a Changing Climate (ARCC) under the projects, CREW, LUCID and SNACC have evidence to suggest that Green Deal measures such as heavily/inappropriately insulated homes could increase the risk of summer overheating and create new problems in the future.

So what should you do for the best? 

The ARCC have produced a guide for anyone with concerns and provides information on those properties at higher risk and the key principles for addressing overheating, including ventilation.

Continuous Mechanical Ventilation products can help with improving indoor air quality and elevate some problems inherent when highly insulating properties, such as condensation in the winter and overheating in the summer. The Green Deal guidance refers to the use of continuously running Extract Fans and Positive Input Ventilation, all of which are products offered by Nuaire. Advice should also be given by your Green Deal Assessor on any ventilation requirements as a result of the recommendations being made to improve your home.
