Building Energy Efficiency in Hong Kong: Case Study of a Commercial Building with BEAM Plus Provisional Platinum Rating (Existing Buildings)
Hong Kong currently has over 42,000 existing buildings that account for over 90% of the total electricity consumption in the territory. The Energy Saving Plan by the Hong Kong Government and the HK3030 Campaign by the Hong Kong Green Building Council (HKGBC), both put forth an electricity consumption reduction target of buildings. Expediting green building adoption with better energy performance is identified critical to achieve the target. To advocate low carbon sustainable built environment, Business Environment Council (BEC) has undertaken a Transformation Project which aims to upgrade its Headquarters (with building age of around 20 years) to an energy wise green building with BEAM Plus Platinum rating. This paper presents the details and major findings of the project. Since 2013, a number of energy-retrofit measures has been implemented, which including lighting system upgrade, installation of variable speed oil-free air cooled chiller, light and motion sensors, smart metering, and commissioning of building services equipment. These implementations aim to reduce electricity consumption of the building, future replacement, maintenance cost, and to enhance the energy efficiency of different building facilities. Meanwhile, driving behavioural changes of the occupants is also an important element for energy conservation. Stair-Days was one of the adopted measures which contributed to approximately 5% reduction in daily electricity consumption of lift. As an overall result, the electricity consumption of BEC Headquarters was reduced by 24% from 2013 to 2015. Together with other green features and environmentally friendly operational practices introduced, the BEC Headquarters has achieved the Platinum Rating of Provisional Assessment under the BEAM Plus Existing Buildings. It is the first commercial building in Hong Kong which has achieved the highest level of recognition under the BEAM Plus assessment for existing buildings. This project showcases how a 20- year-old building could contribute in energy saving and green building transformation in Hong Kong.
