Savings

Improved Efficiency Brings Increased Savings. Energy is one of the largest operating costs for building owners and operators. Inefficient buildings drive up operating costs by losing energy through systems that are not optimal. At O’Brien Energy Solutions, we show you exactly how these structures and systems can be economically retrofitted to provide immediate cost savings.  By integrating energy supply and demand strategies, O’Brien Energy Solutions can help significantly reduce your operating cost. Reinvest your savings into facility improvements or apply them directly to your bottom line.

Arguably, the most simple retrofit that will generate significant savings for building owners is to replace high wattage incandescent bulbs with low wattage compact fluorescents. Self-ballasted compact fluorescents (CFLs) are the wave of the future for home and commercial applications. CFLs have a longer life, use less electricity, and have more color options than incandescent bulbs. They feature flicker-free starting and silent operation, and may be used in any standard 120-volt socket. These lamps operate cooler so you can put them into any fixture without overheating and equivalent brightness can be achieved with a much lower wattage. For example, a 15 watt fluorescent will give the lumens of a 60 watt incandescent light bulb.

The energy savings is considerable - 45 watts of consumption.These high-efficiency compact lamps pack a real punch with savings as high as 75% over standard bulbs and they last up to 10 times longer, cutting utility costs on average of $75.00 per installed unit.

The following table shows how replacing a single bulb can produce significant savings over time:
