Frequently Asked Questions
What documentation do you require to perform a rating?
There are a number of plans and documentation we require, and all of this is contained on our Job Request Form available here.
In addition to the information given in this form, we will also need:
- Elevations, Site plans, House plans inc NORTH point, floor coverings & additional ventilation locations.
- Window Schedule showing height and width.
- Door Schedule (if possible) showing height and width.
- Electrical Plan showing locations, wattage and if downlights are sealed or unsealed.
Will my house rate as 6 stars?
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.
What if I haven't chosen my windows or insulation levels yet?
I'm only doing an extension, do I have to have the whole house rated?
