Greener high-rise flats attract COP26 praise
Energy demand has been reduced by 80%.
Three of Glasgow’s best-known high-rise blocks have attracted international praise for their improved environmental performance.
The renovation of Queens Cross Housing Association homes at Cedar Court, in the city’s Woodside area, was commissioned to address fuel poverty – and, since it was completed, energy demand has been reduced by 80%.
The project’s success has attracted international attention through COP26, with more than 20 organisations from Belgium visiting to see how their environmental performance had been improved and what lessons could be learned.
Maxime Couvreur, Trade and Investment Counsellor at the UK Embassy of Belgium, said: “It is priority for our government to make the building industry more sustainable. It is also a priority to make our existing buildings more efficient. We are very impressed by the work that’s been done here at Queens Cross, and believe it to be industry best practice, and will be taking many lessons away from the work that’s been done here.”
The £16 million project is the most ambitious Queens Cross has ever taken on.
All three blocks have improved low-energy lighting, new insulation, modern controllable heating and hot water systems and triple glazed windows. In addition, new lifts and refuse areas have been installed along with enclosed balconies and increased security systems.
Queen’s Cross’s Director of Property, Enterprise & Regeneration, Rona Anderson, said: “Our objective was to transform them into some of our most desirable homes, to improve residents’ lives and enhance the city skyline and our investment has paid off.”
The refurbishment has also picked up an Architects’ Journal Retrofit Award. The project was designed and managed by Collective Architecture, with a brief to make 314 homes as energy efficient as possible.
Project architect Rupert Daly said: “We took a fabric-first approach to radically reduce energy demand and associated carbon emissions. The energy savings would be locked into the building’s fabric. By retrofitting, rather than demolishing, the whole life carbon footprint of these buildings is likely to be closer to net zero than most new builds.
“Retaining and retrofitting an existing building is always more sustainable and preferable to rebuilding one, if, at the same time, the energy usage can be reduced through fabric improvement.”
Architects forensically investigated the building and found areas where the energy was being lost, such as through walls, windows and concrete balconies, which acted as conductors, drawing the heat from the inside out.
Refurbishing older structures has become more common and a cheaper and more efficient alternative to demolition and replacement with new builds.
The flats, built in 1969, were still in good structural condition, so it was more affordable and environmentally beneficial to refurbish than to rebuild.
Rupert added: “About 80% of buildings in Scotland are still going to be in use in 2050, so, if we’re going to get our building stock to net zero, what already exists has to retrofitted and done well. It is better for the environment to use what is there rather than demolish it and start again.”
Widower George McGavigan, 62, has lived at Cedar Court for 11 years in a three-bedroom apartment with his four children – Chelley, 23, Duncan, 20, Liam, 18, and Alexandria, 15.
George said: “The refurbishment has really improved the place. I haven’t switched on my heating for two years as there is just no need. It has had a huge impact on bills.
“I used to have mould in the bathroom and that’s gone. There is a constant air flow, and it feels healthy and comfortable. It’s a great place to live.”
