As a Chartered Building Services Engineer, I’ve worked on various projects, including Hospitality, Office, Healthcare, Education, Retail, Residential, Aviation, and Data Centres. My involvement has been in sustainable design, using the latest technologies to construct environmentally friendly buildings of all sizes.

The definition of ‘environmentally friendly’ has evolved. It used to mean ‘best practice’ or good performance against benchmarks. However, as the earth’s environment has deteriorated, our goals have shifted towards having a positive impact and aiming for ‘zero’ and beyond.

‘Environmentally friendly’ now means creating positive environmental impacts. This complex task requires the commitment of a generation of professionals. We all need to participate and act now. This is not just a job, but a mission for the betterment of our planet.
