As I understand, it is the role of the building surveyor to ensure the insulation complied with building law when he issues the Certificate of Occupancy.
In the worst case, you have the recourse via the Housing Guarantee Fund's 6.5 year building warranty.
hi carlau, you are sure the wall is required to meet the r value of 2.5 and not the roof?
If its the wall, what type of construction is the house made of? masonry, steel frame or timber frame?
If it is the roof, what type of roof does the house hold? false ceiling or raked roof?
The Energry Reprort stats that all the walls have R2.5 Batts and the Roof to have R3.5 Batts and its also stated on the building plans.
Hi Carlau
My husband and I are builders and I am also an accredited house rater (HER). When house plans are submitted for a building permit, copies of the Energy rating report (which state the energy requirements needed to achieve 5 stars compliance) have to be submitted along with it. The plans are also stamped by the rater to identify them and sometimes also list the requirements on the plans themselves.
Due to the charges that some of the early HER's were charging to assess compliance on each home and the fact that many building inspectors charged just as much if not more to return to check the same requirements some councils, ours included, decided that the builder could sign off a disclaimer to state that all requirements had been adhered to, thus allowing the building inspector to issue the final C of O without inspecting the aspects of the 5 star requirements himself.
The three copies submitted for the permit go to the building inspector, the local council and to the builder and will all have a stamp from the energy rater identifying him/herself. The building inspector should be able to tell you who inspected the 5 star compliance of the home.
The Housing Guarantee Fund (HGFL) has been gone for over 10 years now. The current laws on warranty insurance are managed by the Building Commission and are probably not applicable in this case as it only provides insurance to you for faulty and defective workmanship and/or materials and then is only applicable if the builder is bankrupt, no longer licenced or deceased. Within that 6.5 years of warranty cover there are varying levels of cover for certain parts of your home i.e some things such as certain floorings are covered for far less than the 6.5 years. Many people do not understand what and how warranty insurance really is and many builders don't understand it enough themselves in order to educate clients initially. In saying that the BC could still provide you with advice on whether there is any action you can take and with whom.
Before you do anything, make sure you check and understand the facts. Only external walls (and sometimes the walls between a garage and house) need to be insulated. If your home is double brick down below then the inherent R rating of this wall type may have meant that it wasn't needed on these walls but only on the walls of the upper level. The only way that you will know for sure is to remove sections of plaster and until you see and understand the 5 star report you won't know where it was meant to be installed. There are also many types of wall insulation now; not just the traditional fattbatts, some even look like sisalation but have air pockets (like bubble wrap) so what you think may be only sizalation may not be! The only regulated requirement is that a house built after June 05 has to achieve 5 stars and have either a solar how water heater or a rainwater tank connected to flushing devices. Insulation is not mandatory but is frequently used as a cheaper way to improve a homes rating before the more expensive options are considered. Basically what I am saying is that it may have not been stated in the report that all walls needed insulation so make sure you get a copy of the report and know that you understand it before you start getting too worked up.

Yeh! That is disappointing. I have never heard of someone doing that before, but then again, some people will try anything to put extra $ in their own pocket. I assure you it would only be the minority who would play those games. Good luck.
How do you know there is no insulation in the walls? Have you removed any plaster, or have you attempted to inspect through a gpo ?
