Home Energy Ratings (NatHERS) for New and Existing Homes

Energy Efficiency Advice and Support for Any Home

ECOLOGICA IS

Regionally Based

I  carry out Existing Home energy assessments across central Victoria -  from Bendigo to Ballarat, Kyneton to Maryborough. I can carry out NatHERS energy ratings for new builds anywhere in Victoria, but my focus is on regional and rural projects.

Homes For People

Energy assessing is about heating and cooling loads,  megajoules and R values, star ratings and software programs. But people design, build and live in homes.  A collaborative approach ensures clients' needs, preferences and experiences are brought to each project - every home assessment is unique.

Climate Conscious

Australian homes need to be able to perform in the changing climate, now and well into the future. The introduction of higher building standards in 2024 aimed to help homes to adapt.  But I can also assess designs using future climate scenarios, to aim for greater resilience.

Nationally Accredited

Accredited assessors have achieved a recognised level of professional competence, abide by a code of practice and  have their work audited for quality. Continuing professional development (CPD) activities update skills and knowledge. Accredited assessors also have professional indemnity insurance.

Sustainability Focussed

Residential housing accounts for around 30% of our greenhouse gas emissions. Designing, building and retrofitting houses to be more energy efficient will reduce both emissions and the cost to run them - whether it's from fossil fuels or renewables.

NEW HOMES

Working with designers, architects, owners and builders to achieve high levels of energy savings and meet regulatory requirements for home energy efficiency.

existing homes

Working with owners, landlords and renters to identify and implement actions that will improve wellbeing, save on energy bills and reduce greenhouse gas emissions.

A Building Inspection is a matter of course, before buying/renting. An energy efficiency inspection should be part of the decision making, and contractual obligation, too. 

Thermal imaging

Gaps, cracks, uninsulated areas and thermal bridges can all contribute to heat loss in winter and heat gain in summer. A  thermal imaging camera (FLIR) can be used to detect issues and help identify solutions.

Images below show heat loss and gain through the home. The temperature in the top left corner relates to the crosshatch point, the temperature scale indicates surface temperatures according to the color: blue - coldest, red - hottest.  At assessment the inside was warm than outside, so heat losses would translate as heat gains in summer

More than 1.3 million victorian homes built before 1991 average below 2 stars (NatHERS) for energy efficiency. For the people in these homes, this means that winter brings not only cold indoor temperatures and high energy bills, it brings risks to health.
