INDUSTRY COMMENT
Building industry ‘well off track’ to being carbon efficient
n light of a new report which shows that the building sector is way behind in reaching Net Zero by 2030, chief executive of Integrated Environmental Services (IES), Don McLean, discusses how digital twin technology can be used to speed up the process of decarbonising the built environment
I IES chief executive Don McLean
“The findings from the New Systems Change Lab report, showing that the built environment sector in the UK is ‘well off track’ meeting the target necessary to limit global warming to 1.5 degree Celsius by 2030, are extremely worrying.
“The built environment accounts for 40% of the UK’s total carbon footprint due to high and often wasteful energy use in buildings, so it’s clear we need a real push to raise awareness of not only the nature and scale of the task ahead amongst those working in the sector, but also the tools we have at our disposal that can quickly make a tangible difference.
“Designing and constructing more energy efficient buildings going forward is of course essential, but as 80% of buildings that will exist in 2050
have already been built, it is even more important to put focus on improving the carbon performance of existing buildings.
“Whilst thousands of businesses have announced ambitious Net Zero strategies, many are struggling with how to achieve these goals. Without the technology to effectively measure and analyse their buildings’ usage, it is difficult to know where changes can and should be made. And many are wary of wasting money on adaptions that don’t really make a difference.
“This is where digital twin
technology comes in, providing the ability to create virtual replicas of buildings which react as their real- world counterparts would. This allows for new systems to be tested first in the digital twin, showing how these improvements will reduce the carbon footprint of the physical version of the building. Once the costs and environmental benefits of new systems have been established virtually, it can then be decided whether to go ahead and implement the changes. “The report suggests that the energy intensity of buildings needs to drop at a rate almost three times
BSEE
faster than now, so it’s time to step up. If the industry is committed to changing for the better then it is integral that it sees the results of this report, and the many before it, as an opportunity to put sustainability at the heart of its operations, and position itself as a leader in the fight against climate change. “The technology that holds the solution is already readily available, it just needs to be utilised effectively.”
• The Systems Change Lab report is authored by the UN High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, Bezos Earth Fund and World Resources Institute. It calls for transformations across every sector at far faster pace than recent trends to keep the window open to achieving the Paris Agreement’s goal to limit global warming to 1.5°C.
