Becoming an eco-friendly or “green” facility is no longer just hype or trend; it has become a necessity. Green facilities emit lesser and even near-zero greenhouse gas emissions than conventional facilities. Their carbon footprint is smaller. Green facilities do their share in saving the planet also as building occupants go about their daily activities within.
Eco-friendly facilities practice sustainable ways and use only materials that have a less environmental impact, such as green coatings on walls and floors, and cool roof coatings on roofs. Eco-friendly New Orleans white roof coatings prevent the entry of the sun’s heat into the facility. White roof coatings have a reflective ability that bounces off the sun’s rays.
Energy Efficiency in Green Roofs
Roofs are exposed to the sun’s heat during the day, leading to a heat buildup absorbed by an ordinary roof’s membrane. These coatings prevent solar radiation from entering the inner spaces of the facility. With less heat penetrating the interiors, the building achieves a more comfortable internal temperature despite the weather.
With tolerable temperatures in the facility’s interiors, the mechanical cooling and heating systems do not have to work hard to maintain comfortable temperatures. When these systems work less, the facility’s energy costs are also lesser.
One of the distinct characteristics of a green facility is that it spends very little on energy costs. The green facility should be able to maintain comfortable living spaces, much like any other ordinary facility, minus having to spend a fortune on energy bills. Traditional energy usage translates to electricity consumption. Electricity is generated by burning fossil fuels like coal and petrol. This energy generation method results in the harmful rise of fossil-fuel by-products into the atmosphere, in the form of greenhouse gas emissions.
Electricity is expensive due to the high costs of fossil fuels, and its creation is contributing to global warming and climate change. With warmer weather, urban and congested areas are prone to the heat-island effect, which is increased heat retention in a given area. Such temperature changes can produce intense heat waves and lower the quality of air and the global ecosystem. Cool roofs make it possible for facilities to maintain comfortable spaces despite this heat-island effect and promote energy savings.
Energy-Saving Cool Roof Coatings
The most distinctive characteristic of these coatings is their ability to reflect sunlight. Cool roofs mostly come in light colors, which is further sunlight-reflective.
Non-green roofs can be converted into cool roofs with the spray-application of polyurethane-based reflective coatings. Cool roof coatings have excellent adhesion to old surfaces, and asphalt work- and bitumen-based roofings. They also can “flex” or elongate, mainly acrylic- or silicon-based coatings. This prevents the paint from cracking when temperature changes cause the surface to expand and contract.
Nanotechnology has made it possible for infrared reflective (IR) coatings that reflect sunlight and yet allow for dark-colored roof coatings. Pushing the envelope further are cool roof coatings with hollow ceramics that act as an effective heat barrier.
Cool roof coatings are fast becoming the most refreshing solutions to mitigate the effects of global warming and climate change, with lesser energy costs at that.
