18% less heating energy. Just from insulating the slab edge.
That's what energy modeller Rowan Thompson found when he took an existing house model in Wānaka, adjusted it to a standard NZ Building Code specification, and compared its heating demand with and without slab-edge insulation.
It's a compelling example of why energy modelling matters.
Products like Quick Edge can make a significant difference to a home's thermal performance, but modelling allows us to actually quantify that difference rather than relying on assumptions.
And if one component can make an 18% difference to annual heating demand in a particular home, what else could modelling reveal?
In our latest Building Pulse episode, Jim Marsh talks with Rowan about how energy modelling can help architects and builders make more informed decisions, improve building performance and deliver better outcomes for their clients.
