Case Study
Decarbonisation Efforts at Nina Hub
Nina Tower, home to NINA MALL and Nina Hotel Tsuen Wan West, is a mixed-use development located in the heart of the Tsuen Wan district. With a commitment to decarbonisation efforts and enhancing operational efficiency, Nina Tower is undergoing a major upgrade in sustainable infrastructure, including the phased installation of a zero-carbon chiller system, implemented in partnership with CLP Power Hong Kong Limited. At NINA MALL, where foot traffic is particularly high, cutting-edge technology is being integrated to optimise energy consumption. A 5G predictive control system for air conditioning complements the energy-efficient chiller system, enhancing overall performance.
Nina Tower’s decarbonisation strategy centres around four key components: hardware replacement, an AI predictive model, a digital twin pilot and clean energy offset. These initiatives are designed to maximise performance by leveraging AI and machine learning to recommend optimal operational parameters.
Hardware Replacement
Transition from air-cooled to water-cooled chiller systems can significantly reduce energy consumption. Another environmentally conscious upgrade involves using the eco-friendly refrigerant, which has a significantly lower impact on the environment compared to the standard refrigerant.
- Achieve up to 50% energy savings in MVAC system, supplemented by advanced control technologies
- Expected to save more than 8,500,000 kWh under full operation compared to 2024 level
AI Predictive Model
The AI predictive model, which uses a cooling load predictive model developed by CLP Power Hong Kong Limited, is employed in NINA MALL where foot traffic is particularly high. It is equipped with digital control systems for both waterside and airside systems, taking into account environmental and occupancy factors.
The operation cost can be minimised since data used by the predictive model comes from the 5G webcam system for people counting.
The investment has successfully recovered its cost within one year, demonstrating outstanding performance. Looking forward, CCG is studying the feasibility of extending the application of similar prediction models to other projects.
- Achieved estimated energy saving of 675,000 kWh annually since implementation
- 20% improvement in labour efficiency in facility management
- Improved comfort level at NINA MALL
Digital Twin Pilot
The digital twin pilot is being applied in the zero-carbon chiller system at Nina Tower.
The AI model uses data retrieved from the BMS to develop self-trained physics-guided machine learning models for optimising the system. This AI-driven model blends physical principles with machine learning, ensuring an accurate modelling of actual performance.
- Monitor the plant's efficiency and healthiness
- Extend the end-of-life of chillers through a comprehensive maintenance plan
Clean Energy Offset
The electricity consumed by the chiller plants at Nina Tower will be matched by an equivalent amount of Green Electricity Certificates linked to renewable energy projects in Mainland China.

To address our Scope 3 carbon emissions, we conducted a carbon inventory screening and identified Category 2: Capital Goods as a material hotspot. This category accounts for the upfront embodied carbon from our construction projects, as referenced in the SBTi Buildings Sector Explanatory Document. We assess embodied carbon using the cradle- to-site (A1 – A5 stages) approach, supported by the CIC Carbon Assessment Tool, which complies with ISO 14040:2006 standards for life cycle assessment. In collaboration with contractors as specified in contractual agreements, we collect data from purchase records of concrete, steel, façade materials, and other relevant materials to input into the tool. This practice enables the accurate measurement of embodied carbon in key building components and consolidates monitoring data from the construction site. Since FY2023/24, CCG has formally reported Scope 3 emissions under Category 2: Capital Goods for newly completed developments during the Reporting Period.

To better manage food waste at our malls, we actively promote EPD food waste collection programme among our food and beverage (“F&B”) tenants. The participating malls are equipped with collection bins provided by EPD for daily collection by their contractors, which are then transported to the Government’s treatment facilities for further waste- to-energy treatment and composting purposes. Currently, three of our eligible malls are participating in this initiative. In the future, we aim to collaborate with EPD to conduct site visits and assess the operational readiness of all eligible malls with F&B tenants.
Nina Hospitality has a comprehensive food waste circularity management strategy that encompasses food procurement, production, consumption, and waste management.
Nina Hospitality’s Circular Economy Strategy on Food Waste
Food Procurement
- Develop farm-to-table concepts in restaurants to support local businesses and promote a low-carbon dining culture, such as cooperation with Farmacy and ValleyFarm
- Avoid over-ordering of ingredients and food supplies through monthly inventory checks
- Select products with less processing and packaging
- Adopt of eco-friendly plastic-free takeaway containers and cutlery
Food Production
- Fully utilise all parts of food ingredients when planning a new menu
Food Consumption
- Serve food in appropriate portions, such as offering smaller portions for buffet food
- Allow guests to select their portion size when ordering
- Encourage guests to take away their leftovers by carrying out a Bring Your Own Container (“BYOC”) scheme
Food Waste Management
- Implement a daily leftovers and waste log for better menu planning
- Maximise the use of imperfect food or upcycle food waste into new dishes using natural additives or ingredients
- Enhance waste separation at the source through training and ongoing monitoring
- Encourage guests to bring their own reusable containers to take home any excess coffee grounds at our buffet restaurants for personal use
- Provide surplus food to those in need in the community through the charity Foodlink Foundation
- Reduce food waste sent to landfill by using on-site composting machines and transporting excess food waste to the Government’s treatment facilities for further waste-to- energy treatment and composting purposes
- A remarkable 90.4% food waste recovery rate was achieved during the Reporting Period, significantly surpassing our 65% target
In an ongoing effort to increase awareness and knowledge among staff about food waste treatment, Nina Hospitality conducts regular training sessions on the importance of reducing food waste and best practices for waste management, particularly in source separation. Additional guidance has been provided to relevant staff, helping them to comply with food waste management requirements safely and effectively especially on handling on-site composting machines. Through actively connecting with our hotel guests to participate in waste reduction initiatives and training up our staff, food waste recycled by Nina Hospitality has been increased by 45.6% during the Reporting Period compared to FY2023/24.
Plastic Waste
Nina Hospitality is dedicated to reducing plastic waste and safeguarding the environment. Aligned to the Product Eco-responsibility Ordinance of Hong Kong SAR Government, we offer eco-friendly amenities to our guests. Since April 2024, we have also replaced bottled water with canned water and refillable carboy water, with two of our hotels including Nina Hotel Kowloon East and Lodgewood by Nina Hospitality Mongkok leading the way by installing water dispensers to further minimise single-use plastics. In ad dition, all our hotels provide umbrella drying machines since 2023, eliminating the need for plastic umbrella covers.

Our efforts extend to our F&B operations, where we have transitioned to eco-friendly materials for takeaway utensils. We have also introduced double-layer takeaway cups, which remove the need for paper sleeves, and redesigned the packaging of our signature palmier by replacing plastic bags with foil alternatives. To encourage sustainable habits among our guests, we have implemented the BYOC Campaign, which aligns with EPD’s “Plastic-Free Takeaway, Use Reusable Tableware” campaigns. By offering discounts to customers who bring their own containers, we promote eco-conscious behaviour and foster active participation in plastic waste reduction.
Construction Waste & Sustainable Construction Material
While all our development projects have a comprehensive waste management plan, we further reduce construction waste by adopting advanced construction practices, such as BIM, MiC and MiMEP, with off-site prefabrication. We prioritise the use of construction materials with high recycled content, such as pulverised fuel ash (“PFA”) concrete and ground granulated blast-furnace slag (“GGBS”) concrete. In addition, to achieve a high standard of construction waste management, we request that our foundation contractors reuse surplus construction and demolition (“C&D”) materials at other construction sites. There is also a target on waste recycling for all development projects to increase the recovery rate.

Since FY2024/25, water consumption from D·PARK and Pine Care operations has been included in the reporting scope, resulting in an increase in total water consumption. Additionally, as the number of employees at the Headquarters Office grew by 5.3% during the Reporting Period, its water intensity slightly increased in FY2024/25. As for Hospitality, following the gradual transition from an air-cooled to a water-cooled chiller plant system at Nina Hub recently, water consumption at Nina Hotel Tsuen Wan West has increased compared to FY2023/24. The Group is enhancing its data collection mechanism and plans to exclude makeup water consumption of Nina Hotel Tsuen Wan West starting from FY2025/26, ensuring that reported usage reflects what is within our control and can be influenced by water-saving initiatives.
To support this commitment, CCG participates in the Quality Water Supply Scheme for Buildings initiated by the Hong Kong Water Supplies Department (“WSD”). Over 97% of our eligible existing buildings are certified under this scheme, demonstrating our commitment to maintaining superior water quality standards.
We have implemented water conservation measures across our portfolio and diligently monitor our water consumption. These measures include the installation of water meters, flow regulators, and water-efficiency fixtures such as automatic taps. Four hotels are progressing with the installation of low-flow faucet aerators for guestroom water taps, which are projected to achieve up to 30% of water savings. We also conduct regular inspections and replacements of plumbing fixtures, pipes, and drainage systems to promptly detect and repair leaks, thereby reducing water loss. We are also exploring the reuse of the bleed-off water from the cooling tower for flushing purposes wherever possible2.
2 A total of 3,236 m³ of reused water was recorded across five existing buildings during the Reporting Period. We are currently enhancing the tracking of water reuse metrics to cover a wider scope of existing buildings.
Case Study
Water-Smart Taskforce Programme (WaterTAP)
To assist customers with high water consumption in managing their usage more efficiently, the WSD has partnered with the Centre for Water Technology and Policy at the University of Hong Kong (“HKU Water Centre”) to implement WaterTAP. We have volunteered four of our properties to explore ways to reduce our water consumption and support the Hong Kong SAR Government’s goal of achieving a 10% reduction in per capita freshwater consumption by 2030, based on 2016 levels.
As part of the programme, smart water meters have been installed on site to automatically record water usage data, detect anomalies such as leaks, and securely transmit this information to a centralised server for analysis. This advanced smart water meter system helps us to visualise water consumption patterns and provides valuable insights into the factors contributing to high water usage.
Nina Hospitality promotes sustainable use of water by posting a message card in hotel rooms to encourage guest participation in the bed linens and towels reuse programme.
