Electronic and electrical equipment are rated and evaluated based on different factors. Energy efficiency is definitely the most important aspect worth considering when calculating energy stars and ratings. Energy efficiency evaluations are not limited to just electronics, it has become equally important for homes to be assessed for energy consumption patterns. Investing money on a five star rated AC would have no meaning if the house itself is ridden with faults.
Energy ratings for homes are based on the simple criteria of heat insulation. An apartment is considered more energy efficient (thus eligible for higher energy star ratings) if it maintains a thermally comfortable environment for the occupants. If the amount of energy leaked in or out of the house is within a predetermined limit, it passes energy test and is awarded a rating. Most developed nations have their own unique evaluation parameters, but at the end of the day they all attempt to bring down energy consumption. In countries other than our own, governments are trying to ration energy usage and bring it down as much as possible. When smart houses get five star rated AC units, the overall impact on energy sources is minimal.
Unbeknownst to many of us, the overall costs of running an AC is more than the cost price of the unit. Some assessments put running costs at 60% of life-time costs, which is less if we consider the fact that cost price is just 11% of total costs. There is no reason why you should not try to lower running expenses as much as possible. By buying a five star rated AC, you are setting the way for huge savings in bills and maintenance costs, which is always a good thing for all of us.
Secondly, there is a nature conservation angle to it as well. Energy we use in running our air conditioners, room heaters and electrical appliances comes from burning fossil fuel which is a non-renewable source of energy. That resource is ending up fast and if we do not take proactive steps at conservation, it is going to run out soon leaving our future generations in darkness.
Where to buy five star rated AC?
Buying home appliances is an easy job these days. You can either shop online or walk into an electronic store in your neighbourhood. Energy star rated items need to be bought only after due consideration, do not just pick an item because it says energy star somewhere on the label; make sure that you are getting the real deal.
