The buildings of the future; delivered now.
Rapid decarbonisation is required to halt climate change, and the built environment has a significant role to play. Designing for net zero carbon is a collaborative process requiring input from every area of the industry, and as building services engineers, we are uniquely placed to co-ordinate that process.
The World Green Building Council, and subsequently the UK Green Building Council, have produced frameworks which set out the definitions and principles of Net Zero Carbon (NZC) buildings, and how to achieve them.
It is important to understand that NZC does not just mean net zero energy input, although energy consumption does need to be significantly reduced. A NZC building must have both low embodied and operational carbon, creating an overall low lifecycle carbon value. Energy will come from renewable sources and remaining carbon emissions must be offset – but only after all other reductions have been made.
New buildings are the low hanging fruit; by working to these frameworks from the early design stages, we can find the most sustainable solution to fit your budget and needs. Improving existing buildings is more challenging and there is no one size fits all approach, but with the range of technologies available today, solutions are there to be found.
The London Energy Transformation Initiative (LETI) are leading the way with design guides which are a good starting point, and should be developed by an experienced, diligent and pragmatic design team to arrive at an optimised design for the building and development.
Our NET ZERO CARBON PROCESS
We have developed a bespoke process to achieve net zero carbon designs. The process incorporates input from all the key stakeholders and designers, which is then evaluated using advanced TM54 and lifecycle carbon modelling to understand the operational and embodied carbon emissions of the development.
