Save Energy Oman, the campaign that aims to encourage the Sultanate to reduce its energy consumption, has announced some thought-provoking statistics when it comes to conserving the nation’s energy use. According to the latest report from the Electricity Holding Company homeowners with air conditioning units more than ten years old will be able to reduce their electricity bills by 20-40% by simply replacing their old units with new and more efficient models.Recognising that in the climate of the Middle East a/c units are essential for a comfortable indoor atmosphere, the campaign is urging homeowners, offices and businesses to invest in energy efficient air conditioning systems. “Central air conditioners are loads more efficient than window and room a/c units. As well as being quiet, discreet and easy to operate, central a/c units nowadays use 30-50% less energy to produce the same amount of cooling as air conditioners made in the mid 1970’s,” says Karl Matacz of EHC.With an approximate lifespan of 15-20 years, central a/c units are a worthwhile investment, according to sources at the EHC. Higher efficiency models are available on the market, and rated according to their seasonal energy efficiency ratio (SEER), which indicates the amount of energy required to provide a specific cooling output. “Many older systems have SEER ratings of 6 or less but today the minimum recommended SEER allowed is 13. Consumers should look out for the ENERGY STAR® label for central air conditioners with SEER ratings of 13 or greater, and should consider using air conditioning equipment with higher SEER ratings for significant savings,” said Karl.EHC also urges consumers to be aware of ‘Special Offers’ on older a/c units, as the saving made on the purchase could be cancelled out at the end of the first summer season, by the additional energy bills.
