On principle, the VTC would consider RCx for all existing buildings with central building services installation, as well as when chillers are scheduled for replacement and maintenance, subject to funding availability. Retro-commissioning (RCx) Energy-efficient Systems and Applications Renewable Energy Solutions Education and Social Engagement Environmental Targets and Performance Outlook Pathway to Environmental and Sustainable Development Awards and Recognitions Message from Executive Director Carbon Reduction in Action Photovoltaic (PV) Panel Installation In December 2021, a pilot set of solar panels was installed in the Wofoo Foundation Dr Joseph Lee Whole Person Development Education Centre, with the Feed-in Tariff Scheme in place. It is scheduled to commence installation in 2025 on more premises. The system will incorporate data analytics for educational purposes. Solar Water Heating System A solar water heating system has been installed in the VTC Halls of Residence (Tsing Yi). This system captures energy from solar collectors on the rooftop to generate hot water for guests. Lift Modernisation In a five-year rolling programme, lifts and escalators across VTC premises are to be replaced and upgraded, subject to funding availability. Modernisation of lift systems at IVE (Kwun Tong) and the VTC Kowloon Bay Complex has already been completed. Solar Window Films Application of solar window films is underway across 12 pilot sites. These films effectively reduce heat gain, increase UV protection and reduce electricity demand of air cooling systems. Smart Meters Currently installed at 16 VTC sites, smart meters provide realtime data on electricity consumption. Chiller Plant Replacement A five-year rolling programme is underway to replace and upgrade all aged central airconditioning systems with high-efficiency models and optimised cooling control systems across VTC premises, subject to funding availability. Replaced two lifts at IVE (Kwun Tong) and VTC Kowloon Bay Complex Save about 5,000 kWh per month Lighting Infrastructure Upgrade Existing lighting installations will be progressively replaced with energyefficient LEDs. These will be integrated with occupancy and motion sensors and timer controls to automate their operation and optimise energy usage. Outdoor solar lights have been installed to harness sunlight as power source. Replacement of Window-type Air Conditioners Replacement of window-type air conditioning units with centralised high-efficiency systems is included in the VTC Tsing Yi Complex and the Hong Kong Institute of Vocational Education (IVE) (Kwai Chung) retrofitting projects.
