Description of the building:
FEAST (Food by EAST) underwent a major renovation in 2020, during which significant efforts were made to adopt various green features recommended in the Swire Properties’ Green Kitchen Technical Guidelines. As a result, the newly revamped premises received the highest “Three Leaf” rating, making it the first food and beverage (F&B) operator in Hong Kong to achieve this top accolade.
Retrofitted initiative:
FEAST is a bustling eatery featuring international cuisine with authentic Asian specialties and international favourites. It operates in an efficient and environmentally friendly way, giving the customers a green dining experience to lead a sustainable lifestyle.
The success of FEAST showcases the significance of engaging with F&B operators from the early stages and reaping benefits throughout the operations phase of an F&B outlet. Notable green features adopted during the renovation include:
Aspects Green Features Adopted
Energy
- LED lighting;
- Variable speed control for kitchen exhaust fan and fresh air supply;
- Heat recovery function adopted for dishwasher and gas cook stoves;
- Power analyser to monitor kitchen electricity use;
Water
- Flow rate restrictors to conserve water;
Waste
- Recycling of food waste, coffee grounds, used cooking oil, glass bottles, metal cans, etc.
Outstanding Operational Management
- Strong commitment to sustainability supported by corporate policy, environmental targets and communication with customers and staff
Observed benefits other than energy saving:
- To enhance the sustainability performance and staff wellbeing.
- To provide thermal comfort for kitchen personnel.
- To promote resource recycling and water saving.
General observations of the retrofitting project:
Launched in 2017, Swire Properties' Green Kitchen Initiative is a platform for landlord-tenant partnership aimed at helping F&B tenants design and operate a sustainable restaurant.
The scheme includes a set of comprehensive “Green Kitchen Technical Guidelines” that fosters sustainability conversations wellbefore tenants’ fit-out or renovation projects. F&B tenants who integrate highly effective sustainability solutions into the design of their premises are recognised with a “Green Kitchen Award” for their efforts to maximise environmental performance and enhance staff well-being.
The Green Kitchen Evaluation Framework
The framework includes recommendations categorised under five key areas of sustainable restaurant design and operation:
- Energy Efficiency and Reduction
- Water Efficiency and Quality
- Exhaust Efficiency and Kitchen Environment
- Resource Recycling
- Outstanding Operational Management
Based on the number of items adopted, tenants are eligible for recognition with the One Leaf, Two Leaf or Three Leaf (highest) rating.
Upgrade to Green Kitchen Initiative 2.0
Building upon the enduring success and popularity of the Green Kitchen Initiative, Swire Properties rolled out “Green Kitchen Initiative 2.0” in 2022. The upgraded version included updated mandatory requirements based on latest government regulations and introduced prerequisites for the Green Kitchen Award, i.e. LED light fittings, flow controllers, and food waste recycling. Enhancements were also made to ensure that emerging best practices and innovations are incorporated.
Tenant Participation
As of September 2023, over 100 F&B outlets across Swire Properties’ Hong Kong and Chinese Mainland portfolios have participated in the Green Kitchen Initiative, highlighting the continuous growth and engagement of the participants. Among them, 32 tenants have achieved the highest possible Three Leaf rating.
