In the future will environmental assessment for building permits be more than just energy rating?

Comparison of the potential impact for energy emissions of the COAG commitment to move from 5 star to 6 star ratings versus the potential for reductions in emissions due to production of building materials is startling.

At Building Design Compliance we sometimes wonder whether the energy rating software calculations of the energy consumption have become the goal rather than the reductions in emissions that we understand to be the endgame.

Building materials constitute 17% of the 30% of Australian Global Warming impacts. By contrast the 19% savings in Energy consumption from moving from 5 star to 6 star is equivalent to under 5% of greenhouse gas emmisions. Based on re-build rates of 20% of the existing buildings it will take around 50 years to actually achieve these reductions.

These figures come not from “Planet Ark”, but the Building Products Innovation Council (BPIC) writing in the September 2009 issue of the Australian Building Regulation Bulletin.

BPIC recommend that for a more comprehensive environmental assessment consideration should be given to the impact of materials onĀ emissions. According to BPIC this assessment should include: (more…)
