Solar Energy Is Renewable Window Energy

Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat. Solar energy is what interests us at Polar and it is becoming more and more popular around the world as a renewable resource. It is pollution free, noise free and versatile. The worldwide demand for solar energy is currently much greater than the amount supplied.

National Geographic states that “solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars.” What an amazing resource! Still, just this month in a speech at Solar Power International 2012, former President Clinton stated that $22 are given in subsidies for fossil and nuclear energy for every one dollar given to renewables.

It’s interesting that such lucrative industries like the fossil fuel industry require subsidies . . .

So then if knowledge is power and power is energy we’d like to put our energy, generated from our knowledge into educating you on how easy it is to harness the sun’s energy with your windows. Then the power is in your hands to select the best ways to save energy.

What does solar energy have to do with your windows? Here are the ways in which we measure the solar energy saved (or gained) through your windows:

Solar Heat Gain Coefficient (SHGC) is a measurement of the fraction of incident solar radiation admitted through a window. It includes both radiation that is directly transmitted and radiation that is absorbed and subsequently released inward. The SHGC is expressed as a number between 0 and 1. The higher the window’s SHGC, the more solar heat it transmits into the living space.

U-factor: a measurement of the rate of heat transfer through the window. A low U-factor is desirable since it indicates low heat loss in winter and low heat gain in summer. The U-factor is the inverse of the R-value. Energy Rating (ER) Value: a measurement of the window’s overall energy performance based on the thermal transmission heat loss, solar heat gain performance and heat loss due to air leakage of the window. The higher the ER value, the better the energy performance of the window during heating season.

The ENERGY STAR® program in Canada is a voluntary arrangement between Natural Resources Canada’s Office of Energy Efficiency and organizations that build, manufacture, sell or promote products or new homes that meet the ENERGY STAR® levels of energy performance. Polar windows exceed most if not all industry efficiency ratings. They are designed and oriented to your home’s geo-specific location. In respect to the sun’s movement around your house, we can actually reduce the number of times your furnace and/or air conditioner cycle – in some cases up to 30% less, hence the term “Window Power”.

The choice we make when we use alternative measures to fuel our homes is one that puts you in “power”. The sun is there for all of us and we are here to help you keep it working for you just that much longer.
