Energy Audit to Support Net Zero Roadmap
During a workshop on 27th of June EGS-plan presented the results of an extensive energy audit of the SCB Headquarters in Bangkok. The project was implemented in close cooperation with The Creagy, a Bangkok based consulting company which develops the Net Zero Roadmap of SCB. The workshop was attended by the management and the operation and maintenance team of SCB.
The energy audit comprised of three buildings of SCB Plaza with a total air-conditioned floor area of 225,000 m2GFA. The audit was conducted according to ASHRAE Standard Procedures (Level 1& 2) and started with a walk-through site visit to assess the condition of the façade, the typical use areas (e.g., office), AHU rooms, electrical rooms, chiller systems and BMS. In the following months extensive measurements – both long and short-term – were conducted to assess thermal comfort, air quality, lighting quality and energy efficiency in the building. GFA
In the second step solutions were developed to increase energy efficiency and reduce energy costs as well as improve thermal comfort. According to EGS-plan’s holistic approach on buildings we included the façade, the MEP systems and finally renewables into our assessment. Together with the facade installer MBM and the façade supplier Schueco various concepts were developed with the goal to enhance or replace the existing façade. In the next step improvement potential was identified including the replacement of AHUs, the installation of PICV valves and a recommissioning of the BMS. Finally, the potential for the installation of a building integrated photovoltaic system was assessed on the roofs and in the facades of the buildings.
With a cost-optimized combination of all energy efficiency measures including the previously replaced chiller plant, energy savings of up to 50 % are possible. The implementation of the recommended energy saving measures will bring SCB significantly closer to their Net Zero goal.
