Pros and Cons of Skylights on Energy Efficiency

When most people think of skylights, they may not be focusing on energy efficiency. The most notable feature of a skylight is simply natural light. Technology still hasn’t provided an artificial equivalent for the aesthetic and mood-lifting benefits of sunlight streaming downward into living spaces from above. While windows allow indirect light into the house laterally, an overhead skylight provides the most direct way to gain the beneficial exposure to real sunlight indoors.When it comes to efficiency issues, however, a residential skylight presents both good news as well as downsides. Here are some skylight pros and cons:

Energy Efficiency Benefits

• Extra heat in winter. Sunlight passing through glass carries heat energy along with it that warms rooms and helps reduce furnace expenses during daylight hours. Energy costs can be reduced during the heating season.

• Free lighting. During daylight hours, a skylight reduces dependence on other electrical light sources.

• Passive ventilation in summer. Skylights that are openable permit enhanced cross-ventilation by letting out rising warm air that naturally accumulates at the ceiling. This upward flow of air creates a “stack effect” in a room that continuously exhausts heat through the open skylight while pulling in fresh air through open windows.

Energy Efficiency Drawbacks

• Heat gain on summer days. Solar heat entering through a skylight in summer may cause your air conditioner to run longer to compensate and increase energy costs. Placement of a skylight—such as selecting the north-facing side of the roof with less solar exposure—can reduce heat gain.

• Nighttime heat loss. Once the sun goes down, glass in a skylight may allow indoor heat to radiate out of the house into the colder outdoors. In winter, this may require more heat from your furnace to compensate and energy consumption may rise. Skylights that utilize glass with low-emissivity coating can help reduce heat loss in winter.

If you're considering installing a skylight, ask the professionals at Air Assurance for more information about the potential energy efficiency pros and cons.

When You Leave Home, Don't Lose Energy -- Set the Temperature Correctly

Is your thermostat set to the same temperature when you are away as when the family is home? A more energy-efficient setting during away times can significantly reduce monthly utility expenses. During the cold months, you can also set the temperature lower when everyone is asleep.If you have a programmable thermostat, the times can be set according to your programming instructions. The temperature can be set to automatically reduce at a certain hour and then increase to provide a higher comfort level when necessary.Advantages of a Programmable Thermostat

• Programming in advance – You are able to program your desired settings either in the beginning of the week, month, or even the start of the season. Most programmable thermostats have an override function in the event you need to make last minute changes

• Accurate readouts – The digital backlit display gives a much more accurate reading than the older dial-type thermostats. Newer thermostats have indicators for low battery and the latest models can even warn you if there is a malfunction in your heating and cooling system.

• Wireless control – You can access the thermostat by a smartphone from anywhere. If you are called away on a minute's notice and forget to adjust your settings, just use your phone to make the necessary changes from your location.

• Smart recovery features – Several programmable thermostats have the capability to bring the temperature to the desired level automatically. You just set the time and temperature. The thermostat will calculate the amount of time necessary to ensure the temperature is reached by the desired set-point time.

The main purpose of programmable thermostats is to help you save on energy expenses, while keeping an acceptable comfort level in your home. There are several types available with varying programming options. Savings in energy costs is possible without sacrificing the comfort of your home with the capabilities of today's thermostats.Please contact Air Assurance with any concerns about the correct way to set the temperature of a programmable thermostats for the maximum benefit.

Going on Vacation? Tips for Saving Energy While You Are Away

Vacation season is in full swing, and families from all over are preparing to leave their Broken Arrow home for a few days to enjoy some sun, fun and relaxation. Before leaving, most homeowners take the necessary precautions to ensure their home is locked up safe and sound. However, few think about saving energy while away from home. Ensuring you don’t waste energy while on vacation is just as important as stopping your mail delivery and locking your windows and doors.

Water Heater

Water heaters can be energy wasters if you’re not home to enjoy the comforts of warm water. Fortunately, most models feature a vacation mode that you can simply switch to. For gas models without a vacation mode, turn the setting to pilot. For electric models, you can either switch the water tank off at the breaker or turn the temperature to the lowest setting.

Heating and Cooling

There is no sense in running your air conditioner while you are away, and doing so is simply wasting energy. Saving energy while away from your home will require either turning the A/C off or turning the thermostat up to about 85 degrees during the summer. If you are vacationing during the winter months, set the thermostat to about 50 to 55 degrees. This temperature is warm enough to keep pipes from freezing.

Electronics

Televisions, computers, radios, blu-rays, coffee machines and many other small appliances and electronics are energy vampires that continue to drain energy even when they are turned off. Saving energy while on vacation will require unplugging these items from the outlets. Before you leave, take a walk through your home, unplugging any items that won’t be in use while you’re away.

Saving Energy Tip

Keep drapes, blinds and curtains shut to help prevent the sun's rays from heating your home, while making your house more energy efficient.

For more information about saving energy while you're away on vacation, contact the experts at Air Assurance. We have provided heating, air condition and plumbing services to the Broken Arrow area since 1985.

Get a Federal Tax Credit for Installing a Geothermal Heat Pump

A geothermal heat pump is the most energy efficient and durable system you can use in your home and a federal tax credit exists to help you offset the higher cost of these systems. A heat pump cools and heats by moving heat from one place to another. While air-source heat pumps depend on outdoor temperatures to harvest or deposit heat, a geothermal system executes this process by using underground resources.

Since temperatures vary little underground throughout the year, the geothermal system is more efficient at both heating and cooling. They use a loop field that's buried deeply underground as the resource for depositing heat in the summer and the resource in the winter. It's the loop field that adds the extra cost to a geothermal heat pump, and the tax credits will help offset this expense.

Homeowners who install a qualifying system can deduct its entire cost, with some exceptions, to receive a 30 percent credit on federal taxes. This credit applies to primary and secondary homes, but not rental properties. It even applies to new home construction. The program is so generous because geothermal systems have a low carbon footprint. The loop field can last 50 years or more, and the heat pump itself may last 25 years.

The federal tax credit won't cover the cost of the ductwork or a backup heating coil, but it will cover the cost of the desuperheater, an upgrade that takes the heat from your home and uses it to heat your water.

A geothermal system must meet the requirements for the Energy Star program to qualify and it must be installed on or before December 31, 2016. You can deduct the entire cost of the system, except for the ductwork and heating coil, to receive the credit. There's no cap on the amount you can deduct for the loop field and the remaining heat pump and desuperheater if you opt for this upgrade.

If you'd like more information about a geothermal heat pump and the federal tax credit, contact Air Assurance, serving Broken Arrow homeowners with HVAC services since 1985.
