Centre to accelerate net-zero buildings for cities

The new Centre for Net-Zero High Density Buildings will investigate how to make buildings in heavily populated areas more energy-efficient to reduce carbon emissions, lower heating bills, and bring eco-friendly construction products to the market. 

Led by the University of Edinburgh the research partnership combines the Universities of Glasgow, Strathclyde, West of Scotland, Edinburgh Napier University, and BE-ST – Scotland’s construction innovation centre. The centre draws together £5.6 million investment from industry, education, the public sector and the community.

Based at the University of Edinburgh’s newly opened Edinburgh Futures Institute, the Centre will test new prototypes and retrofit buildings with low-carbon materials, heating and cooling systems, and energy storage technologies. 

The scheme will target buildings which typically house some of the UK’s lowest earners, including many public sector and key workers.  These groups tend to spend a higher proportion of their income on energy bills, yet are more likely to experience health problems associated with cold and damp housing.

Among methods being trialled are net-zero heating systems, more sustainable construction methods, and natural insulation materials – using plants such as hemp and sisal – which can be manufactured in Scotland and reduce issues associated with plastic insulations.

Other approaches include low-carbon heating technologies, which are more energy-efficient than boilers and fives time faster to install than heat pumps, researchers say.

Researchers estimate the UK’s 6 million households living in flats, combined with urban commercial buildings, produce around 20 per cent of the country’s annual carbon emissions.

The scheme will test its approaches in Edinburgh and Glasgow, which have the UK’s highest proportion of flats. These feature a patchwork of historic stone tenements, modern flats, and commercial premises – offering a useful testing ground for green building technologies. 

Researchers estimate that Glasgow and Edinburgh city regions combined may require around £35 billion investment for low-carbon retrofitting and construction over the next 25 years, to help achieve net zero goals.

The scheme’s recommendations will be shared with industry and government, to inform how buildings across the country are retrofitted to achieve net-zero targets.

The initiative is one of several created by UKRI to boost green manufacturing, jobs and skills across the country, known as Green Economy Centres. Another key focus will be to train students in low-carbon retrofitting through partnerships with colleges and academies.
