Sustainability Report 2023/24

Indoor Air Quality • To ensure a comfortable environment for tenants, the fresh air provision is set at 30% higher than the international standard requirement • MERV 14 filters, active carbon filters and UV-C lights are employed • IAQ sensors are installed to measure air quality parameters, including CO 2 , PM10 and PM2.5 levels • Low VOC materials are used Water Quality • All drinking water tanks are treated with UV and filtered • Drinking water and potable water are tested regularly to ensure they meet WELL standards Nourishment and Health • Certified organic healthy snacks are provided to encourage healthy eating habits Visual Comfort and Adequate Daylight • The building floors have been designed with increased headroom, resulting in 23% deeper penetration of daylight • The lighting design incorporates glare limits and colour-rendering requirements to ensure visually-comfortable indoor environments • Approximately 90% of the development’s area offers access to outdoor views CASE STUDY Safeguarding Tenant’s Health and Well-being at XRL Project To align our healthy building initiatives with international best practices, we are advancing a holistic suite of health and wellness measures at our latest XRL project. Physical Activity • We encourage occupants to walk and exercise. A new walking network connecting West Kowloon Cultural District to the Central Kowloon Route Landscape Deck through the West Kowloon Parkway will be established, enhancing walkability and promoting healthy lifestyles • Outdoor spaces, such as the rooftop observation deck and podium landscape deck, are provided to promote physical activities Thermal Comfort • Buildings within the development are separated by at least 50 metres, allowing wind penetration and an expansion of greenery areas. This mitigates urban heat island effect and provides a thermally-comfortable outdoor environment • Humidity within the office area is regulated at 30% to 60% as the optimal level for thermal comfort • Occupants can control temperature in the space through thermostats present within the thermal zone Acoustical Comfort • Absorption materials are incorporated within the buildings to achieve a comfortable reverberation time • The interior is designed to achieve desired ambient noise levels, ensuring that exterior noise intrusion does not impact the health and well-being of occupants The project is set to obtain six major sustainable building certifications. Below are highlights of various health and wellness measures adopted at the project: (Rendering) Sun Hung Kai Properties Limited | Sustainability Report 2023/24 < 65 > Our Reporting Approach Message from the Sustainability Steering Committee Our Business Our Approach to Sustainability Value Created for the Environment Value Created for People Value Created for Customers Value Created for Supply Chain Value Created for Community Appendices
