The award recognises companies whose services have led to outstanding improvement in energy performance and carbon abatement (if applicable), contributing to capability building in energy and carbon abatement. The award recipient is:
Award Category: Outstanding Energy Services Provider 2023
G-Energy Global Pte Ltd once again was awarded the outsanding service provider this 2023 after their first award EENP award in 2018.
Headquartered in Singapore with subsidiaries in Southeast Asia countries, G-Energy Global Pte Ltd proposes sustainable solutions most suited to clients’ project’s needs.
One of G-Energy’s key highlights is SamWoh Smart Hub, which is the first privately-owned positive energy building. At SamWoh Hub, innovative solutions such as Solar-Driven Digitally Controlled Chiller and Smart Fan Coil Units (FCU) were installed.
At SamWoh Hub, Solar PV power is fed directly and utilised by the Solar-Driven Digitally Controlled Chiller. In the event when there is an excess of solar PV power after utilisation by the chiller, this remain power is converted to AC and channelled to the building electricity grid. This technology helps to reduce energy loss (4 to 5 percent) from DC to AC conversion and AC to DC conversion on Solar energy that is utilised for the chillers. It also reduces initial investment on both solar inverters, circuit breakers and cables that channel the solar PV power to the building electricity grid.
The Smart FCU operates at a high chilled water temperature of about 12oC without adversely affecting the relative humidity in the space while achieving good total system performance. The operating fan speed can be varied from 30 to 100 per cent, as controlled by built-in smart controller.
At SamWoh Hub, the design and installation of these energy efficient equipment resulted in an estimated total amount of energy saved to be 1,152 MWh (47.55 per cent). The carbon abatement is estimated to be approximately 467.5 tCO2 annually.
The installation of the Solar-Driven Digitally Controlled Chiller and Smart FCU has contributed to total savings from the Chiller Plant and Airside of about 258MWh (13.95 per cent) which translates to the carbon abatement of approximately 104.7 tCO2 annually.
