  • 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.
