About Us

Efficient Living is a leading Australian ESD consultancy based in Sydney. Our sustainability consultants help clients create a built environment for the future –   a future where smart design and efficient systems reduce the impact of climate change, enhance our quality of life, offer increased resilience to our communities and lead to a more sustainable construction industry.

We are a team of engineers, architects, building designers and environmental scientists – which means we have an enormous knowledge pool to draw upon when providing leading ESD and policy advice to renowned designers, architects and developers working on some of the most exciting residential and commercial projects around the country.

Since our founding in 2000, we have optimised the thermal comfort and energy efficiency of thousands of projects, from architectural homes and multi-residential estates to landmark multi-use commercial precincts. We also guide clients through rating certifications such as Green Star, NABERS, WELL and Passive House.

A net-zero emissions future complete with low emissions buildings has always been our goal, but now the rate of change is faster than ever before. We lead our clients through the evolving policy developments and industry trends while managing their business priorities, which means we always provide the most practical, buildable solutions that focus on the highest sustainability impact for within the available budget.

  • We’ve had very thorough and efficient service from Efficient Living with each commission. In particular, we appreciate their willingness to test different options and problem solve for complex and unusual design situations.

    Alexandra Matyear, Whitcher Matyear Architects

  • Efficient Living have for the past few years provided excellent service at a reasonable cost and always on time. They make helpful suggestions to resolve any problems. I would recommend them to anyone needing advise in building thermal efficiency.

    John Smit, Mirvac Group

  • Our design had large amounts of glass to maximise the available view and included appropriate shading devices and thermal mass internally. Using the standard BASIX DIY program we were unable to comply even using high performance windows. Using thermal modelling provided by Efficient Living the building easily passed the BASIX requirement and the information enabled us create a building that performed even better thermally using simple design solutions.

    Peter James, Watershed Design

  • Efficient Living make us look good and help us deliver better outcomes. They make our buildings more efficient and our clients enjoy the benefits, then we take the credit. Thanks, Efficient Living

    Adam Pressley, All Australian Architecture

  • Efficient Living has provided me with energy assessments and advice, Section J and BASIX certification and advices for the last 8-10 years. On every occasion, it has exceeded my expectations in regards to timeliness and efficiency and all at a reasonable cost. On the occasions where adjustments have been required, they went out of their way to accommodate the project design intent with highly gratifying results. I recommend them very highly.

    Emile Jansen, Jansen Architecture

  • We have worked with Efficient Living for over ten years and have always found Tracey and her team to be responsive and professional. Our projects are far from standard and we have always been able to arrive at a workable solution in terms of BASIX compliance, that keeps everyone happy - including the environment.

    Kristin Utz, Utz Sanby Architects

  • We count on Efficient Living for all our BASIX needs, including reviewing and improving BASIX reports when we purchase sites with approved DA’s. Efficient Living has been able to standardise requirements across our developments, saving on compliance costs and making implementation easier. We would highly recommend Efficient Living’s professional services to provide solutions for saving water, reducing energy and improving thermal comfort.
