Modern Building



Improving the supply chain management in the construction phase to reduce and capture the embodied carbon footprint for the development of a building during construction.

The Problem

As we build increasingly energy-efficient buildings that use less and less energy to run, the proportion of the building’s lifecycle carbon that comes from the embodied carbon becomes more significant. Embodied carbon is still largely untapped. The greatest opportunity for impact on embodied carbon comes at the design stage, in particular in the building structure. Subjecting to the type of building, by the time a building is occupied, somewhere between 30-70% of its lifetime carbon may already be accounted for. We thus try to capture the carbon saving opportunity as early as possible way before the building’s reaching its operational stage.     


In order to better capture the opportunity to reduce embedded carbon, decisions from key stakeholders such as architects, structural engineers, quantity surveyors, and the client during the design stage are essential. Yet responsibilities of the embedded carbon assessment is associated throughout the supply chain during the construction phase. Once a product/ material is chosen, the selection of suppliers would be the next important part in embedded carbon management. 

Examples of measures during Design Phase

  • Low carbon passive design

  • Architectural design to optimize modular and standardized design

  • Maximize reuse of major building elements from existing buildings

  • Us of high recycled content materials in facade and structural components

  • Design of structural elements and choice of materials that results in lower embodied energy

  • Use of local materials

Examples of measures during Construction Phase

  • Adopt low-carbon procurement through the following:

    • Select energy-efficient manufacturers

    • Adopt local sourcing and local supply chain

  • Adopt low carbon logistics mode of materials transportation

  • Efficient energy us on-site during construction

  • Efficient freshwater us on-site during construction

With the above in mind, as a contractor, we are looking at accounting for embodied carbon during the construction phase, mainly in materials and on-site resource use. This includes (i) material data such as timber for temporary works, steel, concrete, curtain wall- aluminum, curtain wall- glass and (ii) site resource consumption data such as water, electricity, diesel and logistics data during materials transportation. 


We are looking for an innovative and efficient way in assessing the embodied carbon as scoped above. For example, how to better automate materials tracking and site resource use monitoring in construction phase. 

Urban Skyline



To improve our efforts in being a sustainable property developer, we are looking for technology solutions that can provide a supply chain solution with the below features:


  • Embodied carbon capture & calculation system in the supply chain and for construction site

  • Optimize the supply chain process to reduce the embodied carbon 

  • Solutions to demonstrate potential improvement in embodied carbon footprint 


We are looking for:

  1. Intention to expand the business in both Hong Kong and mainland China markets

  2. Companies with capabilities in 1, or ideally all, solutions


The ideal solution should at least:  

  • Be easily adopted during the design stage such that the final design (mainly structural design) would have the least embodied carbon comparing to a baseline (or original design)

  • Be able to capture the embodied carbon during construction. 

  • Demonstrate its compatibility of commonly used engineering or building modeling tools (e.g. BIM)  

  • Enable the embedded carbon information to be incorporated to science-based target (SBT) submission
