Renovate rather than rebuild

1 May 2024

The ACA is delighted to present an online webinar on Tuesday 28 May with energy efficiency champion Jenny Edwards and her colleague Duncan Hall. This informative session will provide invaluable advice on creating highly efficient, all-electric, climate-resilient homes, highlighting the delights of small spaces and the transformative power of renovation.


Many in the housing industry suggest that to achieve energy efficiency, the only solution is to knock down homes and start from scratch. But there is another way. New homes are often sold on how much more people can have – more floor area, more rooms, more square metres for the dollar – implying this is of more value. However, bigger doesn’t necessarily equal better, argues Jenny Edwards. More doesn’t make people happier when it equals more resources (financial and environmental) to build, more to heat/cool, more to maintain and clean.

​Australia’s homes have great potential for renovation where existing housing stock can be transformed into energy-efficient, all-electric homes. Life Cycle Analysis highlights the sustainability benefits of renovation solutions. People value comfortable, affordable, sustainable homes and good science-based design advice.


Jenny Edwards is owner, Managing Director and Lead Scientist at multi-award-winning practice, Light House Architecture & Science. She is an ACT licensed Building Energy Efficiency Assessor and was named 2023 Energy Efficiency Champion at the National Energy Efficiency Conference for her free advocacy and education work about residential energy efficiency over the last 15 years. Jenny established Energy Imaging in 2008, which was the first Australian business to combine the use of air leakage testing and thermal imaging in the local construction industry. In 2010, Jenny established an energy efficiency consulting business – Scinergy – which won the ACT Sustainable Cities Energy Innovation Award in 2010 for its innovative, scientific approach to improving energy efficiency in the residential construction sector. In 2019, the ACT branch of the Institute of Architects awarded Jenny the Clem Cummings prize for “outstanding contribution to architecture and the built environment”.

Duncan is a Canberra-based architect and Design Lead at Light House Architecture and Science. With previous experience in high-end residential architecture and delivering construction training in rural Timor Leste, Duncan is a passionate believer in the value of the middle ground – modest, well designed and delightful homes that put quality of life ahead of architectural showpieces.
