The Athletes Village project achieved significant reductions in carbon emissions through improved building design and construction techniques. Specifically: 1) Building designs focused on energy efficiency, using improved insulation, airtight construction, and heat recovery systems to reduce energy consumption by over 60% on average. 2) Construction methods like on-site soil reuse and rail transport of aggregates reduced embodied carbon in materials. 3) Operational carbon is predicted to be reduced by 83% per apartment compared to typical buildings, avoiding over 13,000 tonnes of CO2 emissions annually through efficient lighting, appliances, and connection to low-carbon power.
