Sustainability Report 2020/21

In line with the steadfast green building commitment, we make strenuous environmental efforts at our construction sites, shopping malls and managed properties. Among the latter is the ICC which is Hong Kong’s first building to earn BREEAM In-Use International’s highest honour. Maximizing Energy Efficiency Since 2012, ICC has conserved more than 17 million kWh of energy – equivalent to a reduction of 13,000 tonnes of carbon emissions. Today, following our long established management approach of ‘I – intelligence, C – collaboration, C – continuity’ and adherence to various ISO standards, ICC maximizes energy efficiency with innovation devices such as double-deck lifts and destination control systems, Internet of Things (IoT) technology and smart lighting controls. More than 90% of the common area has been upgraded with new-generation LED lights, whose use is reviewed and optimized. An IoT-based energy monitoring system optimizes the performance of air-side equipment, particularly air-handling systems. This year, we continued to collaborate with The Hong Kong Polytechnic University to optimize our central cooling and air conditioning. We also retrofitted our central air conditioning to enhance its life span and performance. Apart from that, a testing and commissioning system utilized machine- learning and visualization tools to analyse data and optimize our energy use.

This digital twin model will store the building’s lifecycle information, assisting the leasing team in showcasing it to potential tenants. Thanks to the model, existing tenants benefit from retrofitting proposals that are better designed and managed. And the model will also connect with the existing building-management system for performance enhancement.
