Energy savings

Canadian researchers at the

(ARC) have proved that by combining direct solar collection and heat storage technology with existing structural insulated panel system (SIPS), energy consumption for space heating could be reduced by 48%.

The study focused on measuring energy consumption during a peak energy load period from February 1 to May 15, 2005. ARC combined existing SIPS technology with thermal solar panels embedded in exterior walls to create a more energy efficient building envelope in a test module.

On average, 65% of Canadian home energy consumption goes to space heating. Another 20% goes to hot water generation, with 15% being used in the form of electricity.

The research was conducted using three one-room test modules. The first test module represented a standard home with walls made of 2" x 6" wood studs with R-20 batt insulation.

The second test module used SIPS technology – with walls made of six-inch PlastiSpan Expanded Polystyrene (EPS) Insulation cores between two oriented strand board panels – an emerging technology in the construction market.
