Unless you, like me, live in a tropical climate you naturally know how necessary it is to focus on energy to save you from the all-pervasive sun. Then again, you also need to familiarize yourself with the large energy bills figures that make your heart miss a beat, and frenzied calculations are made on paper, in the head, or if you’re like me-on your iPad, trying to manage your fiscal deficit. Industrial Roofing Contractors FB page is one of the authority sites on this topic.
If we have darker colored roofs perchance-like 90 percent of the United States, then the sun’s peak heat has contributed to more than doubling the need for energy and thus the deficit.
Wait and hear (read) me out before you run around to paint your roof.
Such devices have to do dual functions. Most people use metallic roofs to focus on the reflective surface, but what they don’t realize is that the metal doesn’t mirror infrarots back to heaven. Reflective surfaces, too, can and do collect debris, and that significantly reduces the benefits. This is not especially important for people in colder climates, since heating accounts for 29% of energy consumption, while air conditioning accounts for a real 6%. A brighter roof makes sense to them, though.
A second reason I listed for implementing such programs. For this, let me clarify the idea of’ Urban heat island.’ Most of our urban spaces and structures are heat-absorbing surfaces because of the material, or colour. The formation of smog because of the same aggravates the problem more. Apply to that the absence of foliage, and just multiplies the’ heat-gain’ of an urban space. This, sadly, means a greater drain on energy reserves.
Ideally, a cool roof structure will guarantee zero heat production, UV and Infra-Red reflecting back into the atmosphere, and a decreased and more sustainable climate by minimized use of CO2 spewing air conditioners. Different approaches to this effect occur-one can choose one, or a mix of many different methods.
Inherently cool roofs Inherently reflective vinyl roofs can represent 70-80 percent of the sun’s rays, with strong reflectance and emittance measures, which avoid radiation damage from houses. Compare it with the weak asphalt representation of 6-26 per cent, the gain is simpler.
Coated roofs Another alternative is the addition of a solar reflective coating to an existing floor. The website of the CRRC (Cool Roofs Rating Council) has details about a number of products on the market.
Green roofs When it comes to a green roof several nations have played with different strategies. The elements of a Green Roof are plastic materials, porous structures, ventilation, trees, and sometimes a wind shield. The benefits of such a policy are countless-improved air quality, outstanding ventilation, pleasant climate & a special and flourishing eco-system.
