The building is optimized for its design thanks to energy simulation, focusing on the building envelope and the HVAC system. Simulation results show a reduction of energy usage from 240 to 83 kWh/m2/year, equivalent to a 74% reduction in energy consumption, cutting CO2 emissions by 716 tons.
The solutions to optimize the building shell include maximizing the ratio of glass on the wall, using insulating bricks, SHGC 0.37 glass, and installing an insulated roof.
The solutions to optimize the engineering system include reducing the heat load capacity from 1100kW to 625kW, installing a high-efficiency air conditioning system, a heat recovery system, and an energy-efficient lighting system.
