Building Environmental Assessment Method (BEAM)

Nowadays, everyone talks about “Green”! Eat “Green”, act “Green” and live “Green”! How to live “Green”? There is an increasing awareness on the environmental impacts of buildings among the public when Hong Kong is crowded of more and more high buildings. The BEAM (Building Environmental Assessment Method) which is the Hong Kong assessment tool for green buildings was developed in 1996. It embraces a range of good practices in planning, design, construction, and management, operation and maintenance of buildings, and is aligned with local regulations, standards and codes of practice. This scheme is applied to green buildings including New Buildings (NB), Existing Buildings (EB) and Interiors (BI) for shops, offices, retail, contributing to the development of ‘Green and Sustainable buildings’. After assessment, building user will be given with a single performance label to demonstrate the overall qualities of a building.


Although BEAM is voluntary assessment, a building with a BEAM PLUS green building label is a recognition of a building with a lowering environmental impact than its peers, using less energy, water and materials than conventional buildings that in turn lower greenhouse gas emissions and finally reducing the environmental impact of buildings. Not only these, the built environment and users’ satisfaction are further improved by a safer, healthier, more comfortable, more functional and more efficient building. 

To enhance the brand image of your building as an efficient and environmental-friendly area as well as increase users’ satisfaction by providing a safer, healthier and comfortable, more functional and more efficient building, we, here, supports your buildings on the measurement in BEAM. Followings are the categories that we are capable to conduct.
