Maintaining a comfortable living environment in the throes of summer or in the midst of winter can be difficult, especially when you’re trying to be conscious of conserving energy and reducing emissions. We are told in the summer to use air conditioning sparingly and to draw the curtains, open the windows, and use fans whenever possible. In the winter we are told to limit our use of heat and to bundle up. We’ve heard all of this before, but the constant effort of trying to stay cool or keep warm can end up being quite a lot of work for minimal results on your energy bill and a minimal reduction of emissions. In Canada in particular, our climate changes so drastically that this is a very real concern. It is encouraging to know, however, that there are inspirational Canadian companies working hard on finding solutions to these lifestyle concerns that also impact our environment.
One company that has come up with a solution is eTime Energy Inc. eTime Energy is a Canadian based sustainable solutions provider “focused on providing North America with the right green technologies that make significant progress towards cutting down carbon emissions and conserving energy.” They spent the last 7 years focusing on the weakest link of energy conservation: the effect of windows on a heated or cooled environment. Their solution to this problem is a simple window treatment that creates an HPS Heat Shield incorporating Nano technology.
So how does it work? The coating is a clear liquid window treatment for glass and polycarbonates that is sprayed onto the surface of the window at one one-thousandth of a hair (8 microns thick). The Nano technology – titanium dioxide spherical particles that cause Infrared (IR) and UV rays to be reflected back – creates a thermal barrier stopping the transfer of heat from entering or exiting the coated window. Coated windows show a reduction in IR and UV ray penetration by 80-90%, a reduction of glare by 70%, and a continuous 10-20 degree temperature difference to uncoated windows. So what does this mean? This coating lowers temperatures by up to 20°C reducing cooling and heating loads by 20-30% and energy bills by 10%.
Their design goals were to deflect the maximum amount of IR and UV rays (to reduce energy loads and consequently emissions) while also maintaining the maximum amount of visible light to diminish the need for artificial lighting. It was also designed to be clear to avoid optical distortion or disrupting the visual field of the window.
Scientific facts and figures aside, this is a practical product that you don’t even notice is there and benefits both our environment and our wallets. Instead of bundling up this winter and installing plastic-film storm windows, perhaps this window treatment is a better way to go. Indeed, I think this is a home-run for eTime Energy and is exactly the type of technology that we have been waiting for.
