Missing roof insulation?!

A client contacted us the other day, saying that “they were in a pickle”.Missing Insulation

The Building Surveyor had inspected the building for final/occupancy. However, they had noticed that the Energy Efficiency Report done (12 months earlier) listed reflective-foil roof insulation. An awful discovery found that there was none on building!

The builder was still on site, but construction was nearly finished. The roof scaffolding was scheduled to be removed on Friday.

What could they do?

Do they take off the roof, add the reflective foil, then replace the roof; an incredibly expensive and time-consuming task? What else could they possibly do?

Could Anderson Energy Efficiency help?

In situations like these, you need someone with a bit of experience and an understanding of legislative and regulatory requirements.

Luckily for the client, the Energy Efficiency Report had miscalculated the amount of added ceiling insulation to the roof-space. The requirement called for R2.5 total (roof+ceiling); this was translated to R2.5 to the ceiling in addition to foil under the roof. However, we found that the required amount of added ceiling was much less (only R1.8).

Long story short, we were able to calculate the difference in heating energy and cooling energy between the ‘as-built’ dwelling & the simulated “complying” building. We demonstrated that the building as constructed had lower heating energy and lower cooling energy, and therefore was better than the “complying” design.

The client was delighted that they had a design that complied with the requirements. Even more so, because they didn’t have to spend any more money on the roof! More than that, the builder’s schedule was not delayed by this mix-up and the home was ready for occupancy on time.

They were also pleased that the investment in our professional consulting was a fraction of the alternative cost.
