Jon Dalton
Jon DaltonManaging Director
Jon has been delivering Sustainable Buildings for nearly 20 years – including achieving the first Green Star rated building in Australia at 8 Brindabella Circuit, Canberra. His sustainability expertise has been recognised by the administrators of various building/construction related sustainability tools, and he is an Auditor and Trainer for Green Star (since 2005), NABERS (2008), CBD (2012) and Infrastructure Sustainability (2012).

Jonathan is particularly passionate about Indoor Environment Quality and the impact it has on occupants. Jonathan is frustrated by a common perception that improving Indoor Environment Quality is at the cost of energy consumption – because in his experience, poor IEQ can actually indicate energy-saving opportunities. But what Jonathan enjoys the most, is making buildings work properly. In particular, identifying the band-aid fixes that may keep a building ticking, but prevent it from realising its full potential.
