Eco-Solution

            Our eco-solution comprises two key components. Firstly, the
            ESI team proposed adjusting the Air Handling Unit (AHU) fan
            frequency, reducing it from 50Hz to 40Hz. Leveraging the
            principles of the Affinity Law of Fans, this approach targeted
            a 20% reduction in the AHU fan’s RPM and airflow volume,
            resulting in a notable 50% decrease in energy consumption.
            Secondly, the team proposed the installation of 4-5 energy-
            efficient  standing air  fans (EBF-Z3  models) renowned for
            their bladeless design and energy efficiency. These fans are
            strategically placed to compensate for the 20% loss in AHU
            airflow volume. By integrating these two eco-solutions, the
            aim was to significantly reduce the energy consumption at
            SGH Campus One.

            Additionally, installing a multi-purpose monitoring device
            (Figure 1) should ensure good indoor air quality (IAQ)   Figure 1: The multi-purpose indoor air quality monitoring
            maintenance, encompassing CO2 levels, room temperature,   device
            and relative humidity, throughout the SGH One Campus
            facility.

            Figure 2 shows the area at the SOC at SGH One Campus, Blk 3 basement, which was selected for experimentation. The AHU
            servicing that area is AHU305.
