Due to the limited technical implementation time, the project is focused on consulting solutions for the air-conditioning system. These solutions increase the investment capital by about 5% but the reduction in energy use compared to the comparison basis decreased from 18.7 to 31.4%:

1. Utilizing an efficient VRV 4 air conditioning system and a local heat recovery system for each floor.
2. Using a LED system with a power density of 6W/m²

The selected measures reduce energy consumption by 22.4%, equivalent to a reduction of 619 MWh of electricity use per year, equivalent to a reduction of 445 tons of CO2 into the environment (with an emission factor of 0.6612 tons CO2/MWh in 2015 and national grid loss in 2015 is 7.94%). The electricity cost is reduced by 1.7 billion VND per year.
