My Generation is the Atlantic Canada representative for SolarWall (r) Solar Air Heating systems. The US Dept. of energy has said this technology is "rated in the top two percent of energy related inventions." Natural Resources Canada calls it the "simplest, most efficient - and least xpensive - way to preheat outside air". If you are the one paying the heating bills you owe it to yourself to explore the savings that SolarWall (r) can deliver.
You can't beat free heat!
Most heating systems consist of two stages - one that generates the heat and the second that delivers it. ie. a furnace burns oil to generate heat and the fan or circulating pump distributes that heat where it's needed. With solar heating systems the sun generates the heat - for free!

How does it save energy?
The most visible portion of a SolarWall(r) system looks like perforated metal siding, however there is a great deal of engineering behind the number and nature of the perforations, how far it is installed away from the building and the manner in which it integrates with the building ventilation system. Sunlight hitting the metal panels warms the surface layer of air, which is then drawn through thousands of small perforations in the cladding and into a narrow space between the wall and the building. The heated air rises to where it is drawn into the facility by fans and dampers. SolarWall can heat outside air 30-70 Fahrenheit above ambient on a sunny day. If the ambient outdoor temperature is zero the SolarWall could potentially heat that air by 70F using the energy of the sun.For a flash animation of this process click "How it Works"
A preheat solar air heating system directs warmed air to a building's primary heating system, which further raises its temperature. Because the air going into the system is already warm, less energy is needed to heat it further. That saves money for the company, and conserves natural resources for the community at large. A solar air heating system augments rather than replaces a conventional heating system.
A stand-alone solar air heating system can also deliver fresh air directly into a building, where it mixes with recirculating plant air. The introduction of a steady supply of fresh air helps to make up for building exhaust air, which in turn means fewer drafts, a more comfortable working environment and savings on energy lost through uneven heating and cooling.
Another advantage of a solar air heating system is that it recaptures heat lost through exterior walls. Heat escaping through a building wall is picked up by the solar collector and brought back into the building. In recapturing this heat, a solar air heating system effectively doubles the R-value of the existing wall.
There are other, less obvious cost saving benefits; for instance, a business using a solar air heating system will need a smaller primary heating system, which reduces both original capital costs and ongoing annual fuel consumption.

Contact us today for an evaluation of how solar air heating could work for you! We use RETScreen software (developed by NRCAN, United Nations, and the World Bank) to analyze the weather conditions at your location, your building characteristics, heating, and fresh air requirements. You can learn more about the software - and take it for a test drive yourself - at www.retscreen.net.
Payback and Incentives:
SolarWall generally pays for itself (through heating savings) in 2-5 years without any grants or incentives.
Currently the federal ecoHeat program provides a potential grant of $6.50/ft2. The NS government provides an additional grant potential of 15%. Agricultural projects in Nova Scotia could potentially qualify for 50% project funding, to a maximum of all combined grants not exceeding 75%. With incentives like these it's easy to see how the economic benefits continue to stack up! It would be difficult to find RRSP`s or other financial vehicles that can compete with the return on investment provided by SolarWall!
Financial Incentives:
Federal: $70/m2 SolarWall ® system (www.ecoaction.gc.ca)
* Must be applied for prior to incurring eligible expenses
* Maximum of $80,000 per project
Nova Scotia: 15% of installed costs (www.conservens.ca.)
* Can be applied for after project completion. Maximum $20,000 per project.
What buildings are a good fit for SolarWall - any building that needs fresh air and heat. Here in Atlantic Canada that's a long list - large institutions such as hospital and schools, industrial plants, warehouses, condos, garages, seniors residences, apartment buildings - the list goes on!
