A 6 star house can come in many shapes and sizes, but it is worthwhile noting that as houses increases in size it can become harder to obtain 6 stars or higher.

While every house is different, and it is hard to know at the outset how the plan will rate, there are a few key elements which can help to achieve a higher rating. One of the most important is ensuring the house has good orientation that allows for solar gain from the North in winter, and effective shading from the summer heat.

Glazing has a large impact on the rating, and it is important to consider the amount of glazing in proportion to the floor area. If there is a higher percentage of glazing, higher performing glazing will need to be considered to offset this. In addition, ensuring the walls, roof and even underfloor has good insulation values.

No problem at all! If you are unsure of your exact specification, we can input the plans provided and give you the most economical solutions for insulation and glazing to ensure you reach the energy efficiency rating. We send these suggestions to you for your confirmation prior to final certification.

Not necessarily! We will initially attempt to meet the energy efficiency requirements for the extension only. However this may be difficult if there is a significant amount of glazing area compared to the floor area, or the orientation may be not be ideal (ie. if the extension is on the South side of the building). In this case we would need to perform a whole of house rating which takes into account a larger floor area to glazing ratio and may enable a successful pass. This exercise will also give a more accurate picture of how the extension will perform in conjunction with the rest of the house.
