Summertime cooling tips for comfort and savings

(From New York State Energy Research and Development Authority)

Stay cool this summer by cutting back on energy use. Energy-efficient air conditioning can make a real impact on comfort and monthly electric bills, especially since cooling accounts for nearly half of the average homeowner's summer energy expenses every year.

"Staying cool and energy efficiency can work together when we adopt simple lifestyle changes like switching off the air conditioning when we're not home," said Roger B. Kelley, President and Chief Executive Officer, New York Power Authority (NYPA). "Conserving energy makes a great year-round habit, so along with our partner NYSERDA, the Power Authority is pleased to help provide New Yorkers this summer with the 'Stay Cool' tips for electric savings."

Efficient cooling helps reduce energy usage when demand for electricity is at its highest. When a heat wave hits and New Yorkers turn on air conditioners at the same time, the impact on the electrical grid is powerful. Taking steps to reduce energy usage when demand is high keeps the system reliable and strong. As part of this summer's STAY COOL Campaign NYSERDA and NYPA offer the following summertime cooling tips:

-- Look for a High Efficiency Model

ENERGY STAR(R) qualified room air conditioners use up to 25 percent less energy than a standard new model, and up to 40 percent less energy than a model more than 10 years old. Also, look for a high Energy Efficiency Ratio (EER). Units with high EERs cost less to operate.

-- Proper Sizing Matters

A properly-sized air conditioner will operate more efficiently and dehumidify more effectively. An oversized unit will cycle on and off more frequently. Short cycling reduces an air conditioning system's life and will not reduce humidity effectively. Undersized equipment can reduce the efficiency of air distribution and accelerate wear on system components, leading to premature failure. When buying a new central air conditioning unit, a Building Performance Institute (BPI) accredited Home Performance with ENERGY STAR contractor can determine the correct size and provide installation of the unit.

-- Chill Only When You're Home

For central air conditioning, an ENERGY STAR qualified programmable thermostat allows homeowners to automatically adjust to a more comfortable temperature when they are home. While away, homeowners can set the temperature to use less cooling energy. Residents save three percent on energy costs for each degree they turn the thermostat up from 72 degrees.

-- Don't Forget the Adoring Fans

ENERGY STAR qualified ceiling fans can help cool a home without greatly increasing electricity use. They improve airflow and create pleasant breezes.

-- Change Your Habits

To reduce a home's heat and moisture, and reduce energy when demand is greatest, use ovens, washing machines, dryers, and dishwashers in the early morning or at night when it is generally cooler outside. Use a microwave to cook, or barbecue, if possible.

-- Turn It Off

Save electricity and reduce wasted heat by shutting off lights and electronics. Seldom used home electronics should actually be unplugged from the wall or shut off with a power strip. Items like DVD players, VCRs and cordless phones use 40 percent of their energy while in the "off" position to power functions such as clocks and remote controls.

-- Take a Whole House Approach

Houses work as a system. Insulation, heating and air conditioning, air sealing, water heating, ductwork, windows, and doors all work together to determine efficiency. A BPI accredited contractor will perform a comprehensive home energy assessment to help you map out a plan to improve your home's energy efficiency.
