Stephen Hennessy

With more than 30 experience as a building services engineer, Stephen has
worked on some of the most important and iconic buildings in Australia,
including Parliament House in Canberra and the Sydney Opera House.

Stephen has authored a broad selection of technical papers and publications
relating to building services, and delivered keynote presentations at
industry and professional forums over many years.

Stephen’s expertise is widely recognised, and he has been invited to sit on
a range of Boards, committees and panels, including the NSW Division of the
Property Council of Australia, the Chartered Institute of Building Services
Engineers ANZ Region, Standards Australia ME62 and AS/NZS3666 committees, the
Department of Climate Change and Energy Efficiency ‘Commercial Building
Disclosure Implementation Forum’, and the NSW Department of Environment and
Heritage NABERS Advisory Panel.

In 2007 Stephen was awarded a Silver Medal by the Chartered Institution of
Building Services Engineers for service to the industry.

Stephen entered the engineering field in the UK nearly 30 years ago via a
circuitous route, first as an indentured design technician, followed by some
building services engineering contracting work. It was an enforced period of
contemplation following a serious parachuting accident, however, which led
him into the ranks of professional engineering.

Today, as a Director of WT Consultancy, Stephen devotes his time to team
leadership with a particular focus on energy and life cycle optimisation.

This emphasis on sustainability has been developed over 20 years, most of it
as an engineer with and then director of AHA Management (during this period,
he was at the front end of the sustainability movement; this included roles
such as Partner Support Manager with the pioneering organisation SEDA,
assisting organisations to identify and implement energy savings
opportunities) and subsequently as a Director of Steensen Varming Australia).

Stephen has undertaken a significant number of NABERS energy and water
ratings. He is recognised as one of Australia’s most prominent prolific and
proficient assessors, and as a consequence he has been engaged to provide
training on behalf of the scheme administrators.

Stephen’s extensive experience in the design, operation, auditing and
management of buildings and building engineering services continues to be
leveraged to the benefit a wide range of clients. He believes that, given the
reality of climate change, this type of experience and expertise has never
been more critical. For Stephen, the era of the building professional has
arrived.
