Make the Most Out of Air Sealing

Air sealing is becoming more important as energy codes throughout the country change and requirements become more stringent. The 2012 IECC requires blower door testing and a visual inspection of all new homes to make sure that it meets the air leakage requirements. Currently, Maryland and Illinois are the only two states that have fully adopted IECC 2012, but in 2014 it will become effective in California, Massachusetts, and Washington as well.  North Carolina also has taken parts of the 2012 IECC code and implemented it into their own state energy code. Many other states are set to adopt the 2012 IECC requirements by 2015.

A recent article from Builder Magazine, provides some insight on what areas of a home should be sealed in order to get the biggest return on your air sealing investment. According to the article, Dave Wolf, a senior research and development project leader for Owens Corning Science and Technology has identified the 5 leaks in a house that will have the biggest effect on air infiltration.  

Wolf's research determined that sealing these 5 areas will have the biggest impact: 

1. Recessed lights
2. Duct boots
3. Top plate to drywall at attic
4. Garage wall
5. Band joists

A blower door test and visual inspection will determine if in fact these areas are properly sealed, and if they aren't the builder can correct the issue(s) to comply with 2012 IECC requirements or simply to make the home more comfortable and efficient for the occupant.

Air Barriers: The What, the Why and the How

With stringent energy codes being enacted throughout many states, and the desire for more efficient, and cost-effective commercial and residential buildings, the use of air barriers is becoming more important.

What is an air barrier? Air barrier systems are made up of a number of materials assembled to provide a barrier to air leakage throughout the building enclosure. Basically, an air barrier prevents the infiltration of outside air into a building and the escape of inside air to the outdoors. 

Why should you install an air barrier? Air barrier systems:

• Reduce air leakage in commercial buildings by an estimated  83%, save on gas bills by more than 40%, and cut down on electrical use by 25% or more. (According to the National Institute of Standards and Technology).
• Prevent conditioned air from escaping the building and helping to reduce energy costs by keeping the conditioned air in and the unconditioned air out.
• Help to keep pollutants from infiltrating the indoor environment, improving the overall indoor air quality.  They also help prevent water vapor which in turn helps to prevent condensation problems and mold growth.

So, how do you know that the air barrier system will meet the specifications for performance, design, materials, and assembly, included in the ASHRAE guidelines and in multiple ASTM Standards and Test Methods? SkyeTec offers air barrier testing for homes, large buildings, and commercial properties to provide assurance that the air barrier system is in fact functioning properly and that the property is sealed tight. 

SkyeTec begins the air barrier testing with an infrared imaging scan of the interior in order to locate any possible areas of air infiltration. Next, a Bower Door test is conducted to determine the air leakage. If any areas of significant infiltration are found, a digital photo and thermal image of that area are taken. 

When functioning correctly, air barrier systems are a very effective and beneficial addition to a building's construction. 

Survey Shows Energy Efficient Homes Gaining Popularity

A survey conducted by Green Builder Media shows what we have seen first hand over the past couple of years, consumers are becoming more aware of the benefits of owning an energy efficient home. The Consumer Green Preferences Survey was conducted in March with a sample size of 582 adults from around the country. The goal of the survey was to understand what people want when it comes to sustainability, energy efficiency, purchasing patterns, etc.

The results are good news for builders who have implemented an energy efficiency program , whether it be ENERGY STAR® Certification or the HERS Index Program. Of those polled, 79.8%  said they would look for a green rating (i.e a HERS rating) when buying a new home, 85% of those people said that they believe an energy efficient home would sell faster.  Also, when asked what comes to mind when they think of green living, 4 out of 10 people ranked energy efficiency as the first thing.

For builders that haven't started building energy efficient homes yet, the survey results are a good indication of where consumers are headed.

SkyeTec Recognized with a 2013 Leadership in Housing Award from the EPA

SkyeTec is pleased to announce that we have been recognized by the U.S. Environmental Protection Agency (EPA) with a 2013 ENERGY STAR Leadership in Housing Award. This award recognizes the important contribution we've made to energy-efficient construction and environmental protection by verifying 3,126 ENERGY STAR® certified homes last year. Collectively, these homes will save our customers approximately $1,256,652 on utility bills and reduce 14,517,144 pounds of carbon dioxide each year. 

To earn the ENERGY STAR label, a home must meet strict guidelines for energy efficiency set by the U.S. EPA. ENERGY STAR certified homes are more than 30% more efficient than a standard new home.

SkyeTec works hard throughout the year to make it easy for builders throughout the U.S. to build energy efficient homes, and we plan to verify even more homes for 2013.

The Importance of a Healthy Indoor Environment

Have you heard that each year, $3.5 billion is spent in the U.S. for asthma related illnesses due to dampness and mold issues in homes? Or that $50 billion is spent per year for lead poisoning in children? What about the fact that each year radon-related lung cancer takes the lives of over 22,000 people, more than drunk driving does? If you didn't know these things, you aren't alone.

The National Center for Healthy Housing (NCHH) is trying to bring attention to the importance of a healthy indoor environment with the new National Healthy Housing Standard.  The goal of the Standard is to reduce preventable diseases and improve the overall health of homes and neighborhoods by reducing the poor conditions that cause such illnesses.  The Standard is designed to complement the policies for the maintenance of existing homes, already in place by local, state and federal governments. However, it is not meant to guide new construction or housing rehabilitation.

NCHH wants to make sure that everyone has a safe haven to return to each day that is free of anything that could cause illness or injury. At SkyeTec, we want the same, and offer a variety of inspections to ensure that a home or building is free of mold or moisture, radon, asbestos, lead based paint, carbon monoxide, harmful Chinese drywall, and more.

Earn Rebates with Georgia Power's EarthCents® New Home Program

Thanks to the EarthCents® New Home Program from Georgia Power, Georgia builders and developers can  build energy efficient homes and earn money for doing so. This program is available for both single-family and multi-family homes and was designed as an incentive to build energy efficient properties.

Qualifying for the rebate is easy, simply implement a HERS program and work with an energy rater to ensure that the homes earn the required HERS Index score of 77 or less. The home must also be served by Georgia Power and have all electric heating and water systems.

• Single family homes-$600 per home. Plus an additional $250 rebate is available for homes with a heat pump water heater or a solar water heater.

• Multi-family properties- $150 per unit

Builders that implement a HERS program also receive valuable market differentiation by being able to market the home's HERS Index score. Plus, potential homebuyers are able to clearly see how their home performs and how much they could save on energy costs annually.

Builders can further boost their market differentiation by cost-effectively adding on a moisture prevention program to the HERS program. A moisture prevention program helps to reduce warranty costs, liability, and customer complaints by ensuring that the home is free of any mold or moisture issues throughout the construction process.  Homebuyers are given peace of mind knowing that their new home isn't hiding a costly mold or moisture problem.

With such a great rebate program and the valuable benefits of the HERS program,  there's no reason not to build energy efficient homes in Georgia.
