Sustainability Reports 2022/23

Our commitment to tenants’ health and well-being is showcased by The Millennity. This project in Kowloon East, directly connected to Millennium City 6 via a covered footbridge and only a five-minute walk from the Ngau Tau Kok MTR station, received Platinum pre-certification from the International WELL Building Institute. It features multiple well-being elements. CASE STUDY Maintaining Tenant’s Good Health and Well-being at The Millennity Indoor air quality: To create a comfortable environment for tenants, the air ventilation rate is 30% higher than the international standard requirement, and we aim to achieve an ‘Excellent’ rating from the IAQ Certification Scheme. The air-conditioning is equipped with MERV 14 filters, and UV-C lights on the ventilation ducts kill bacteria and viruses. Products and materials used in the project, such as carpets, furniture and cleaning products, must not contain harmful substances. Water quality: We monitor the water quality and ensure the requirements of the WELL building standard are met. Nourishment and health: We encourage healthy habits through the provision of healthy and diversified food choices. Around 20,000 square feet of gardening space is open to regular building occupants to grow their own plants. They can even take the crops home. Visual comfort and adequate daylight: The window area is 10% larger than the floor area, allowing adequate sunlight to enter. Physical activity: We promote exercise by providing facilities for physical exercise. Aesthetically designed staircases and other active paths between floors – with natural design elements, such as plants and images of nature – are open to regular building occupants. Thermal comfort: An AI system analyzes energy usage and recommends parameters for the air-conditioning system, to achieve effective savings without compromising occupants’ comfort. Humidity in working spaces is regulated at below 60% for most business hours, an optimal level for thermal comfort. Acoustical comfort: The office floors have sound-absorbing false ceilings with a noise reduction coefficient (NRC) 1 value of more than 0.7. Noise pollution is therefore minimized. Mental health: In addition to the garden space mentioned above, stress management training and fitness programmes are provided. Gardening workshops, harvesting guidelines and planting supplies – including plants and gardening tools – are made available. Accessibility: Barrier-free facilities accommodate the needs of customers and tenants. Biophilic design: The project incorporates natural design elements, such as plants and images of nature as part of its biophilic design. Additionally, a gardening space is provided and is accessible to regular building occupants.

Zero means that the product absorbs no sound.
