New Buildings V1.2
Final Platinum











Hong Kong-Zhuhai-Macao Bridge Substation (HMB Substation), which will be built in the newly reclaimed area at Chek Lap Kok, is designed to provide reliable and stable power supply to the future Hong Kong-Zhuhai-Macao Bridge transportation hub.

Green Substation with Low Carbon Initiatives

Green practices for the substation has been developed with a systematic and innovative approach. The development of HMB Substation addresses various aspects of environmental protection throughout the entire project life cycle.

More than 30% of surface area of the substation will be covered with greenery including vertical green wall, creating a welcoming entry for and blending in with the surroundings of the new transportation hub. Rainwater recycling system and automatic dripping irrigation system will be in place to save more than 70% of water for irrigation. Photovoltaic (PV) panels with solar tracking devices will be installed to maximise the harvest of the solar energy which will further reduce power consumption of the substation. Solar tube will be provided to channel the outdoor natural sunlight to the interior space.

Starting from the design and planning stage, Building Information Modelling (BIM) has been adopted to enhance coordination among different professional disciplines. Green site office will be set up with zero construction waste schemes implemented, promoting the adaptive reuse of temporary construction materials, as well as reducing the cost and wastage for substation construction.

The green HMB Substation not only marks the new environmental standard for substation design, but also the CLP Power’s milestone in striving for environmental excellence continuously.

Green Features

Essential quantifiable features of the project:

  • More than 30% of site area will be covered by greenery
  • All roof area will be covered by greenery or materials with Solar Reflectance Index >78 to reduce the heat island effect
    • A majority of all building materials, including raw materials, will be manufactured within 800km from the site

  • Eco-permeable Paving Block contains recycled aggregates, recycled glass sand and cement will be used to reduce construction wastes to landfills
  • Waste Management Plan with the adoption of sorting, recycling and reuse of construction and demolition (C&D) waste will be implemented. Recycled bins/trays for sorting and collecting inert and non-inert C&D waste will be provided on site. Inert C&D materials will be reused as backfilling materials on site and the remaining will be delivered to public filling areas and sorting facilities for recycling. Wasted paper, cardboard and metal will be sold to recyclers
  • More than 5% of building energy use will be generated from solar energy by the PV panels
  • All electrical appliances, including the split type air conditioning unit, dehumidifier, servers and monitors will be energy efficient appliances complying with the standard of EMSD’s Grade 1 energy label
  • Rainwater harvested system will be provided for irrigation in the substation. It is estimated that more than 60% of fresh water consumption can be reduced
  • Dripping irrigation system will be adopted to reduce more than 70% of potable water consumption for irrigation
    • Lighting quality in terms of illuminance, glare index and colour rendering index of the building will be designed intelligently to achieve high performance

  • LED lighting with motion sensor, daylight sensor, local light switches, occupancy sensor, and timer control at different areas will be provided in the substation to save energy
  • Amenities to enhance the operation and maintenance (including fall arrest system, platform for maintenance at transformer bay, lifting steel beam and platform, haulage lug for installation of transformer, etc.) will be provided to facilitate routine maintenance of the substation
    • Adoption of BIM in the design stage enhances substation optimization to ensure well coordination of the building and the plant facilities

  • PV system with sun tracking devices will be installed to enhance the efficiency of solar energy generation
  • Solar tube and daylight sensor will be provided to enhance the natural lighting provision and reduce energy consumption

Story

Green Vision

Care for Environment is always one of the fundamental core values of CLP Power Hong Kong Limited (CLP Power) and this has been fully implemented in the Hong Kong-Zhuhai-Macao Bridge Substation (HMB Substation) project. 

To provide a highly reliable electricity supply to support the new boundary crossing facilities of Hong Kong, CLP Power takes up the initiative and plans to build the  HMB Substation in a sustainable approach with the adoption of state-of-art green features in the building. This target has been well embedded in the coordination of all participating parties and stakeholders during the whole project. A holistic approach will be adopted for the design, construction, operation and maintenance for HMB Substation, forming strategic blueprint for reengineering the future substation projects.
