Figure 6: Indoor air quality, as represented by air CO2 concentration in ppm, after
implementation of eco solution

Results show that all three indoor air quality variables
measured (CO2, temperature and relative humidity)
remained broadly consistent with those of the initial AHU
configuration but led to significant energy savings (from 360
to 186 kWh) and power-related cuts CO2 emissions (150.8 to
77.9 Kg CO2).

Extrapolation of data

The annual CO2 emissions produced by one air handling unit
(AHU) are calculated to be about 25,766 kgCO2, see Figure
7. Figure 8 shows this extrapolation for Block 3 at SGH One
Campus, which has 40 AHUs.
