One of the projects of our organization is the construction of an ultimate efficient demonstration home designed to produce as much energy as it consumes on an annual basis. The Net Zero Energy House will combine energy efficient building design that reduces energy consumption with solar heat and power generation technologies that supply the home’s remaining energy needs.
The purpose of this project is to increase awareness about how we can live in an environmentally friendly house. This house uses renewable resources to generate energy without harming our fragile ecosystem.
The Net Zero Energy House located in a residential area in London, Ontario has been designed using the latest research tools. The house combines state-of-the-art energy efficient construction featuring ICF (Insulated Concrete Forms) walls, floors and ceilings. Also used are, a solar heating system, ground source heat, photovoltaic (PV) energy and glass sliding walls.
The project demonstrates how the latest technology can be combined with appealing design to create a harmonious and sustainable living environment. The Net Zero Energy House will be open to the general public in the summer of 2006. This house will serve as a tangible example of possible future construction for the building industry.
Green Infrastructure Inc. researchers will monitor the performance of the home for one year. This monitoring will be used to determine if the energy features of the house are performing as expected. Potential improvements to the approach used in achieving net zero energy will also be investigated. Sponsors of the net zero energy house include Amvic, Rehau, Enertran, the Cement Association of Canada, Arc Solar, Schott Solar, Canada Mortgage and Housing Corp., and others.

Solar Technology Improvement
Research and Development: Improvement to Existing Solar Technology
The field of research to improve present technologies in energy production is of crucial importance to the future of humanity as a whole and our survival. There is much room for improvement in our present technologies especially in the area of alternative energies.
Green Infrastructure Inc. is committed to making vast improvements to the existing solar technologies. We intend to make a 20-25% improvement on the heat transfer technology of the existing solar absorbers, which are considered to be the most important components of the solar panels. We believe that we can greatly improve heat transfer technology with our new designs. We strive for a goal of 30% increase in the efficiency of existing solar systems within a year.
In cooperation with leading Canadian universities, including the University of Western Ontario, University of Windsor, and McGill University, we are currently conducting research in innovative technologies, including nano technology, and using conductive plastic to replace existing materials to greatly improve efficiencies in solar absorbers.
Green Infrastructure Inc. is also making, through our research, improvements in the areas of manufacturing technologies, especially with laser robotics. Laser robotics is the next generation of solar technology and is required for vast improvement.
We need your support in helping us to further advance our research in solar technology. And it will be a pleasure to discuss our work and your donations with you.
Pilot Production Series of ArcSolar System with Concentrator Cell Receiver. Note: Indicative data only. ArcSolar System reserves the right to change specifications.
ArcSolar System is a concentrating solar collector that produces both electricity and high grade heat from the one unit, combined with PV modules. Its 16 square meters of parabolic mirror track the sun, and concentrate the sun’s energy on a receiver tube, achieving a total energy efficiency of up to 75%; in addition, it carries 12 standard photovoltaic (PV) modules to use the space most efficiently.
The base is installed on a horizontal surface using twelve steel feet to support the ring profile. The sub-structure can be ground anchors, concrete plates or steel beams.
Ring profile: Rail profile S7 in corten steel, 5.24 m diameter of the ring. Maximum swept diameter with mirrors folded: 8 m, corresponding to 50 m².
Main frame and other profiles: steel, hot-dip-galvanized or with highly corrosion resistant zinc-aluminum-magnesium (ZAM) coating.
2 semi-parabolic mirror troughs at a horizontal distance of 3 m from each other. Each with a width of 3970 mm and a height of 2000 mm. Concentration factor >=30 x. Reflectors are mirrors using 4 mm toughened glass (approx. 95% reflectivity), with ceramic pads bonded on the reverse side for installation. Weight: Approx. 115 kg for the ring profile and 1400 kg for the ArcSolar pvplus incl. inverter and solar fluid.
2n the front and on both sides of the ArcSolar each 4 standard PV modules, fixed at approx. 17° to the ground and tracking the sun together with the ArcSolar from East to West.
