ARC solar thermal building product demonstrates energy savings of 48 per cent

02.06.2005


Researchers at the Alberta Research Council Inc. (ARC) have completed a pilot study identifying a more efficient technology to insulate homes, reducing space heating costs for homeowners. Researchers proved 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 per cent.



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.

“Our technology focuses on the most significant cost related to home energy consumption – heating the physical space,” says Kaz Szymocha, ARC research scientist, Advanced Materials business unit. “This research project was designed to gather enough conclusive data to demonstrate that our technology could be applied in a real world setting. We wanted to improve on existing SIPS technology currently in the marketplace; our results clearly show combining two technologies – SIPS and solar panel technology -- has potential for great cost savings.”


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

“This project supports our mandate of accelerating the adoption of alternative energy technologies in the marketplace,” says Paul Layte, vice-president, Engineered Products and Services division. “This initiative is one of ARC’s strategies for developing, testing and demonstrating solar thermal building products to help reduce energy consumption and greenhouse gas emissions. And, it provides a novel approach to helping consumers deal with high energy costs.”

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. The third module used SIPS technology in combination with solar energy collection panels with direct heat storage ability. Energy meters were used to evaluate energy consumption. As compared to the standard module, the SIPS technology-based module used approximately 75 per cent of the energy, while the SIPS and solar panel test module only used 52 per cent.

Based on an average requirement of 115 GJ (gigajoules) of energy needed to heat a standard residential home (source: Natural Resources Canada), the average customer would save approximately 55 GJ using this combination of SIPS and solar thermal technology.

The project cost $250,000 and was funded 75 per cent by ARC and 25 per cent by Natural Resources Canada (NRCan). In an early stage of this research activity, Plasti-Fab Ltd., a local SIPS manufacturer, also contributed to research funding.

“The Government of Canada is pleased to support this innovative project, which shows real potential for reducing greenhouse gas emissions that contribute to climate change,” said the Honourable Anne McLellan, Deputy Prime Minister and Minister of Public Safety and Emergency Preparedness, on behalf of the Honourable R. John Efford, Minister of Natural Resources Canada. “By combining superior energy-efficient insulation technology with clean, renewable energy, the Alberta Research Council has devised a system that will have far-reaching benefits for consumers today and for generations to come.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
