How we work


We recognise and respect the different priorities across organisations, sectors and countries; scoping is an essential part of our role to ensure we provide you value.

Strategy development

We use a range of services and technical expertise to develop strategies that will achieve commercially focused and long-term sustainability.


We monitor the results of implemented features ensuring client objectives have been achieved, and develop strategies for continuous improvement.

What we do

Our approach is to examine the interaction and integration of systems to identify opportunities for improving efficiency, for example reduce energy demand in new or existing buildings or innovative system waste to resource strategies.

Solutions are tailored to clients’ needs, and cost-benefit analysis is undertaken ensuring economically viable long-term solutions that reduce impact on the environment across an organisation.

This approach is proven as the most cost and resource effective way of managing sustainability.

Our work

Sustainable Integrated Resort, Bali

PT. Destar Rahayu, a development company based in Bali, engaged The GreenAsia Group to undertake a series of Integrative Design Process charrettes to assist in ensuring the long term sustainable development of its 1,014 hectare property in Gunung Salak, Tabanan.

IDP assists in an expected savings of SGD3.1m

A biotech manufacturing plant has projected energy savings of 17.2 GWh per annum, following the efforts made by its engineering department, and supported by the Integrative Design Process carried out by The GreenAsia Group. This could mean an expected $3.1m saved by the major pharmaceutical company each year.

International Rectifier Singapore Pte Ltd, Kaki Bukit Techview

A saving of 40% of their energy bill from IRSG’s baseline calculation which was based on their manufacturing load is expected after the IDP. Ongoing monitoring by The GreenAsia Group in 2014 will fine-tune the systems set in place, and enable IR to look at further savings.

“The GreenAsia Group is bringing to the market a valuable service to reduce energy use, something which governments and companies worldwide are trying to achieve while still growing productivity. The GreenAsia Group makes energy reduction possible through its programmes to design energy needs out of a development. After the EDB’s introduction to the team, and with the assistance of the NEA through the Design for Efficiency scheme, The Group has added various elements to our plan for corporate health, safety and environment issues. We highly recommend their team and commend their dedication to detail.”

Gilda Sagrado, Director, PT Destar Rahayu

Bradley has provided valuable input during this time, and we appreciate his willingness to share his knowledge and experience of the hospitality industry, and his ideas for a new model for tourism.
The first charrette with The GreenAsia Group in December 2013 also gave us the opportunity to look at the many issues involved in the development of a truly sustainable project.”

Peter Lim, Director of Facilities, International Rectifier S. E. Asia Pte Ltd
“International Rectifier has worked with The GreenAsia Group since 2012. The team has shown dedication, commitment, and reliability – all of which has resulted in more than expected energy savings.

American Council for an Energy-Efficient Economy (ACEEE)
Lee Eng Lock’s “world-leading HVAC design and engineering that shows the rest of the world how much energy can be saved through good engineering, innovative design, and attention to details.”

Amory Lovins, Co-founder, Chairman and Chief Scientist of Rocky Mountain Institute
“In my view, HVAC design divides into two eras, B.L. and A.L.—Before Lee and After Lee—so revolutionary has been his impact on how the best mechanical designers think and work. Mechanical design will never be the same. The slow fuse is lit, and the change is irreversible, thanks to the irresistible power of his ideas.”
