We upgraded our windows to double glazing for the house to be more energy efficient. However without the use of heater and evaporative cooling you wouldn't be able to live in it when it gets hot or cold. I was just wondering how can we check if the Builder actually met the energy rating requirements and if they have not then what are our options to have this rectified. thanks go through your paperwork. we had our energy efficiency report/certificate along with all the paperwork that came from certifiers when the building approval was granted. but yeah, as others mentioned, just because the house complies, it doesn't mean it's going to be comfortable to live in. all it means is that given all the inputs they bothered to enter into their system, the energy requirements for heating and cooling will land in a certain range. it doesn't mean that you can avoid using aircond or heater. here's an example of the pretty picture that came with our paperwork to illustrate what that rating actually means: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 10 years ago was a different software than we use now. it has had a lot of changes over the past years.
