Thermapan SIP EnerGuide 80 Solutions
Modelled at EnerGuide 81 and up!

The latest changes to Ontario Building Code require that new homes meet the equivalent of EnerGuide 80 for energy efficiency.

Building with Thermapan SIPs is an easy way to reach and exceed EnerGuide 80 - not just to meet building code, but to save on energy costs!

The table below outlines six potential building scenarios based on a 1,600 square foot house with various Thermapan SIP components. Each scenario has been been evaluated by an independent energy advisor and modelled using Natural Resources Canada’s energy efficiency software. While there are countless combinations of different building components that can go into any given home design, the results below distinctly show that SIPs are an ideal solution for reaching high EnerGuide ratings.

Important Notes:

* ACH is assumed using worst-case scenario. Typical SIP-built homes are very airtight: a blower door test on a SIP home in a Brock University study measured 1.69 ACH @50 PA, well below air leakage levels used in above EnerGuide calculations.

An air-blower test and independent energy audit are required to determine the actual EnerGuide rating of any specific home.
