Finding Sustainability With Energy Efficient Retractable Awnings

Cutting again on power use is an admirable goal, however it’s tough to not use air conditioning in humid summer season heat or to keep blinds drawn (blocking your view) – on sunny spring days and all for a really minimal affect on actual power costs.

Going green is an important consideration for homeowners (according to the Professional Awning Manufacturers Association, that’s important to 75% of homeowners) – but there are such a lot of other upkeep demands on house budgets that going green needs to be a little bit easier. That’s the benefit of retractable awnings; they’re an easy first step in the direction of efficiency:
• Lower the need for air conditioning, so you possibly can lower usage without discomfort
• Don’t require a hefty financial investment, transforming time, or difficulty
• Are an attractive enhancement to a home
• Have easy installation, low maintenance, and long lifetime

The largest expense in a house or business is controlling the temperature, so fundamental energy sustainability projects start with sustaining home or business temperatures efficiently. Almost half of the warmth that builds up in a house or enterprise comes from sunlight. You might imagine that utilizing blinds and shades to block quite a lot of sunlight is sufficient to block the warmth energy, but according to Louisiana-based Claiborne Electric Cooperative, blinds solely block the sunshine from the sun. Once the energy reaches the window, the heat enters the room no matter light, so the blinds don’t decrease real air con use.

Retractable awnings actually block solar power from reaching the window, so it never enters the house. That’s a way more effective method of controlling air con use; in fact, retractable awnings can cut the heat buildup in a room between 65% and 77%, in response to the US Department of Energy.

So what effect does chopping down the solar heat in a room have on energy bills? In broad terms, it cuts air con use around 25% and saves $100 on annual electric bills. The Professional Awning Manufacturers Association (PAMA) commissioned a study covering twelve main cities across the United States, factoring in the window orientation (west, south, east, or equal), whether or not the awning was installed year-round or only in Summer, the kind of glass (normal or solar-reflective), and the way long the Summer seasons are.

The effect of awnings varies widely relying on where many of the windows face, the region, and local energy costs. Sunnier properties – with western-facing home windows or in long sunny seasons – confirmed a marked improvement, though each home reduce cooling power use:
• Sacramento and Seattle by over 60%
• Minneapolis and Boston around 33%
• Washington, DC and Houston around 15%

The actual dollar amount that interprets to can equal even more than the percentage sounds; for example, Phoenix properties cut air-con use by 25% through the use of awnings but realized financial savings totaling virtually $250.

One important finding in the PAMA study: the benefits of utilizing an awning are only in the summer. Year-round awnings increase heating expenses, and that may actually raise annual bills. For example, homes in Atlanta with east-facing windows saved a moderate $50 per summer season on electrical bills – however lost $7 over your complete year. In Boston, the decline in cooling vitality usage had a minor affect on air-con expenses ($1), but cost $65 due to increased heating expenses.

That’s why true energy effectivity comes through putting in a retractable awning.

While air-con expenses are a big amount of electricity usage, heating expenses account for almost half of all energy utilized in a home. Any efficiency solution that improves air conditioning. Retractable awnings do that: they’ll remain prolonged throughout the whole summer season, for the utmost reduction in air-con expenses. As fall and winter set in, they are often retracted, so solar warmth enters and naturally warms the house, retaining heating bills down. By staying open permanently, mounted awnings cut daylight in winter months, considerably increase heating costs, and cancel out any summer utility invoice savings.

In the Northeast, where energy prices are an enormous concern, the New Hampshire utilities system recommends integrating retractable awnings together with your landscaping to extend energy efficiency. Other features – straightforward care, easy use, lengthy lifetime (over 25 years, instead of about 5 years), and diverse answer dyed acrylic fabric choices – make retractable awnings an appealing energy efficiency option. The purpose for retractable awnings increasing recognition in America – and their immense popularity in Europe – is because they provide a simple, comparatively inexpensive, and engaging method to manage energy use.
