The ASHRAE 2025 Technology Awards recognised Swire Properties for outstanding achievements in our data-driven approach to establishing a zero-carbon ready pathway at Citygate Outlets. We won first place in the Commercial Buildings Existing Building Commissioning category for our use of the Cloud-Based Smart Energy Management Platform to continuously monitor energy performance and identify energy saving opportunities, and our numerous energy-saving measures implemented between 2021 and 2024 which achieved a 17.7% reduction in energy consumption.

Organised by the Memorandum of Understanding on Building Retrofitting (Recommissioning) and Energy-Saving Retrofitting of Existing Buildings in the Guangdong-Hong Kong-Macao Greater Bay Area Partner Institutions, this competition recognised the best building retro-commissioning and retrofitting energy efficiency performers in the GBA in 2025.

Two Swire Properties projects received awards in the contest. Cityplaza was awarded the Bronze Prize in the Hong Kong Region – Innovative Technology category, in particular for showcasing the mall’s Cloud-Based Smart Energy Management Platform; while Taikoo Hui Guangzhou received the Grand Prize in Sustainability Application and the Gold Award in the Guangdong Region – Sustainability Application for the multiple energy saving measures it has implemented over the past decade.

Taikoo Li Sanlitun achieved the highest Three-Star rating for the design and operational stages of its PEDF system at the Third China PEDF Conference and Expo in Beijing, according to the assessment standard for PEDF system in buildings.

The PEDF solution implemented at Taikoo Li Sanlitun across Building N15, RED and the underground car park was the first such application in China’s commercial building sector. Since its implementation, it has provided valuable data and acted as a point of reference for the Company and the wider industry.

Taikoo Li Chengdu also achieved the highest Three-Star rating for its design stage PEDF assessment, receiving the award for its self-contained system that produces about 180,000 kWh of power annually.

Swire Properties’ use of PEDF power distribution systems continues to expand. Following our first successful pilot of a PEDF system at Taikoo Li Sanlitun, Beijing, we expanded the pilot to other portfolios in 2024, including Taikoo Hui Guangzhou and Pacific Place and Citygate in Hong Kong. Our use of these systems further expanded in 2025, with the aim of reducing our carbon emissions by about 10% compared to conventional power distribution systems.

In addition to the systems at Taikoo Li Sanlitun and Taikoo Li Chengdu officially achieving the highest Three-Star ratings in their PEDF assessments, the PEDF systems at Pacific Place and Citygate in Hong Kong will be implemented 2026, generating 25,000 kWh and 14,000 kWh of electricity annually respectively.

Taikoo Li Chengdu’s self-contained PEDF system produces about 180,000 kWh of power annually. Energy is generated by solar PV panels on the rooftops of Taikoo Li Chengdu’s retail building and hotel and stored in batteries with a 940 kWh capacity in an energy storage room on the B3 underground floor. The system is controlled by an intelligent monitoring management system.

During the day, the solar panels supply power for ventilation fans, cooling system, electric vehicle chargers and lighting in the car park and hotel offices. Any surplus solar power that is not used immediately is stored in batteries and later used to supply electricity to other low-voltage equipment in the building. During off-peak hours, the building uses grid electricity to charge the batteries. During peak hours, the batteries discharge to help meet the building’s electricity demand and reduce reliance on the grid. When solar generation and stored energy are not sufficient to meet demand, the solar panels, battery storage system and grid work together to supply power to the building.

Swire Properties strives to continuously reduce our consumption of energy. In 2025, we used various technologies and strategic improvements to achieve this objective through a wide range of technical upgrades across our properties.

The existing chiller plant control room at Taikoo Li Chengdu had reached the end of its operational life. In 2025, it was replaced with a new state-of-the-art room that showcases our best SD practices. Features of the new room include:

In 2025, we continued to ramp up our adoption of renewable energy. HKRI Taikoo Hui and Taikoo Li Qiantan secured 80% off-site renewable electricity covering both landlord and tenant operations starting in Q2 and Q3 respectively. Meanwhile, Taikoo Li Sanlitun, [INDIGO], Taikoo Hui Guangzhou and Taikoo Li Chengdu continued to secure 100% off-site renewable electricity. 93% for our Chinese Mainland portfolio are now powered by 100% renewable electricity, achieving net-zero emissions for both landlord and tenants’ operations. 100% of our commercial projects under development are designed to generate renewable energy on-site.

Swire Properties’ Cloud-based Smart Energy Management Platform (“CBSEMP”) was launched in 2019 and was rolled out in phases. Utilising IoT, big data analysis, AI and cloud computing, the platform leverages building operations data to generate energy management and energy-saving insights. The platform is currently implemented at Taikoo Place, Pacific Place, Cityplaza, Citygate, Taikoo Hui Guangzhou, Taikoo Li Sanlitun, INDIGO, Taikoo Li Chengdu, HKRI Taikoo Hui and Taikoo Li Qiantan, and will ultimately be implemented across our Hong Kong and Chinese Mainland portfolios.

In 2025, we expanded our pilot of the digital personal thermal comfort solution at our office on the 19/F of One Island East, integrating fault detection functionality for variable air volume (“VAV”) systems with an occupant thermal comfort feedback and setpoint optimisation algorithm. This enables the system to dynamically respond to occupant feedback, weather variations and VAV system performance. Based on the results of the previous pilot, we expect the solution to reduce cooling energy by 12% annually while improving occupant thermal comfort.

Previously, the Taikoo Li Qiantan indoor lighting system was controlled by timers. During the day, the lights remained fully on, even when there was sufficient natural light; while at night, lighting could not be turned on or off in specific zones, nor could it be adjusted for different scenarios such as cleaning or promotional campaigns. This lack of adjustability caused significant energy waste.

This year, the control system for the entire mall’s lighting system was upgraded. The lights are now controlled by light sensors and different control modes. During the day, light sensors adjust the brightness of the lighting according to the available natural light. At night, different lighting modes can be used to cater to various scenarios. These refinements have enabled annual electricity savings of 100,000 kWh. In the near future, the outdoor landscape lighting will be integrated into the same system to achieve similar levels of control.
