YTL Arena will save 18,580 tonnes of CO2 emissions by repurposing the Brabazon hangars 

By repurposing the Brabazon hangars, YTL Arena Complex will save a significant amount of steel, concrete and carbon emissions during construction, according to a report produced by Bristol based sustainability consultants Hoare Lea.

The Arena will reuse the existing structural frame of the hangars, once home to the iconic Brabazon and Concorde aircraft. This reduces the quantity of virgin materials needed during the construction process, with the main facilities of the Arena being integrated within the structure. The building will be re-clad to improve thermal and acoustic performance and reduce operational energy consumption, yet re-capture the previous industrial nature of the site. 

As part of the initial pre-planning design development works, Life Cycle Assessment (LCA) has been undertaken to quantify the embodied carbon associated with the Arena. This embodied carbon assessment, in tandem with the sustainable procurement plan, will be used to inform material selection to ensure that the environmental impact of the Arena is considered not only during the construction and operation stages, but also further up the chain where materials are sourced and manufactured. 

The table below provides a summary of the avoided emissions as a result of retained materials or process. This can be equated to not requiring 7,200 concrete mixer trips, 8,400 tipper truck trips of extracted soil and 500 long distance trips of trucks carrying steel. 

Activity  Volume / tonnage of material or process (m3 or tonnes)   Avoided emissions (tonnes CO2) 
Creation and transportation of concrete (including hard standing)  -21,400 m3  -5,500 
Evacuation and removal of soil  -28,000 m -80
Manufacture, transportation and assembly of steel  -4,000 tonnes  -13,000 
    Total: -18,580
