Environmentally Friendly Construction

Recently a highly acclaimed architectural firm in Texas published an article that helps identify ways for new and existing homeowners to make their dwelling "green friendly". Gary Gene Olp, Founder and President of GGO Architects outlines steps to becoming energy efficient. Olp and his firm promotes green and energy savings by installing a radiant barrier in the attic. Read on!

Dallas - Sustainability and energy efficiency have become significant selling factors during the home-buying and home-building process. In honor of Earth Day, Gary Gene Olp, Founder and President of GGO Architects, offers key questions to ask when that infamous word “green” makes its way into the conversation.

“Sustainable living is about interpreting natural processes in a modern way,” said Olp. “Many homebuilders and sellers make green claims, pointing to green products utilized in the building process. However, it’s the overall design that constitutes a sustainable design, not just the products used.”

Olp’s involvement in the “green” movement dates back to the early 1970s. He lays claim to the design of the first LEED Platinum home in Texas in 2007, further substantiating his “green authority.” Here are three questions to determine if the home you are buying or building is truly green:

1. How energy efficient is it really? Ask the builder to quantify what the expected annual utility cost will be. With current green building codes, Energy Star ratings and online energy modeling software, this is easily derived from the R value of insulation installed, the quality of the windows and the seasonal energy efficiency ratio (SEER) rating for hot water, heating and air conditioning. If they cannot provide a reasonable answer, perhaps their claims are more guesstimates than engineered performance. Windows should be insulated Southern Low-e, walls should have a minimum of R 24 and the roof should have a minimum of R 40 insulation. The heating and air conditioning can easily have SEER ratings of 16-18 for little extra cost.
2. Demand that a radiant barrier is properly installed on the underside of roof decking. This simple feature is perhaps the most significant design component in our hot Texas climate. Properly installed, it can repel up to 75 percent of the heat gained from the sun in the summer. Every British thermal unit (BTU) of heat reradiated away from the attic of your home means fewer BTUs of cooling required to keep it comfortable, which means smaller utility bills. It is important to make sure the radiant barrier is the metal foil type, and not a faux spray-on paint coating.
3. Do not fall pretty to smart Eco gadgets; instead look for the real thing. Take a compass with you when looking at a new home, and check to see which direction most of the windows are facing. Large amounts of windows on the west are certain to spin your smart electric meter into a frenzy. If most of the windows are on the north, the home may be cooler but generally dark with little natural light. The best orientation for windows is on the east and south for good natural light. Be sure any windows on the south are properly shaded with broad overhangs or large deciduous trees to block out the intense summer sun from passing directly into interior spaces. That same southern sunshine will be appreciated as it reaches deep inside to provide warmth and daylight on cold, gloomy winter days.

And for those who already own a home, it’s not too late to achieve energy efficiency. Homeowners can:

• Install a radiant barrier in the attic. It works equally well for an existing home as it does for new construction.
• Shade the windows facing south and especially those facing west. The easiest, albeit shower way is to plant native deciduous shade trees to block the intensity of the summer sun. Consider adding alternative shading devices like a fixed awning with decorative brackets, hurricane shutters or those really great aluminum awnings from the 30’s and 40’s, which bounce wonderful diffused light back inside.
• Upgrade lighting to compact fluorescent lamps (CFLs) or LED lamps, replace aging appliances with newer high efficiency Energy Star models, and maintain your HVAC equipment and/or at the end of its useful life replace it with a higher SEER rated unit.

Olp, (American Institute of Architects, National Council of Architectural Registration Boards, LEED AP) is the 2011 chairman of the North Texas Green Council Chapter of The U.S. Green Building Council. Olp’s work has been published extensively for the quality of design and to substantiate efforts to push the concept of sustainability.

“The amount homeowners can save with an energy-efficient home is mind-boggling, and it is not just for the elite – green is affordable and attainable for everyone. You just have to know the questions to ask to get started on the right path,” Olp said.

Abaco tropical hardwood decking, from Aljoma Lumber, has a contemporary European design that features a traditional smooth finish on one face and an elegant moulded surface on the other. The moulded surface makes each board slip-resistant and cooler on the feet. Abaco has slotted sides for quick and easy installation of hidden fasteners. Use hidden fasteners designed for tropical hardwood that gap each board with the proper spacing and allow for natural expansion and contraction. By using a hidden fastener on Abaco, virtually all, pre-drilling is eliminated, making installation a breeze. The end result is a beautifully smooth and durable, fastener-free surface. Abaco tropical hardwood decking has a rich mahogany color similar to Ipe and is competitively priced compared to Ipe decking and other tropical hardwoods.

Abaco is the perfect choice for a beautiful wood deck, thanks to its inherent ability to resist rot, decay, termites, splintering, twisting and cracking. Abaco also features all the deck railing components needed to construct a beautifully matched railing. Abaco railing components include balusters, handrails and end posts.

The species used in Abaco are abundant, have fine textures and are dense, naturally strong, extremely durable, and will provide an elegant, exotic look for years to come. Abaco tropical hardwoods are kiln-dried for exterior use and have a superior fire rating when compared to redwood, cedar and pressure-treated lumber. Because Abaco is all-natural, it does not need to be chemically treated. And best of all, it's environmentally friendly.

Saving money around the house continues to be a major pursuit for homeowners nationwide. And with a focus on “going green”, savvy homeowners are looking for ways to cut energy use to reduce utility bills and their home’s carbon footprint.

There are dozens of ways to curb energy use around the home. Sealing drafts by applying caulk and weather-stripping around windows and doors, and applying foam sealer around drafty outlets and piping leading outside can save up to 5 percent on heating costs alone. Most important, installing the proper amount of attic insulation with the proper airflow is generally the best way to save on home energy use.

If you are among the millions of Americans who enjoy do-it-yourself home improvement projects, installing a radiant barrier in the attic space above your home is one of the most effective energy-saving projects to consider.

While radiant barriers are not a new concept, new products on the market are making it easier for homeowners to install them and realize reductions in their energy bills—every month. Overall, a radiant barrier can save an average homeowner up to 15 percent on utility bills.

Rick Jordan of EcoRite Products, a major radiant barrier manufacturer, says the benefits of installing a radiant barrier have long been known by professionals in the construction, roofing, heating and cooling, and energy industries. Only recently have products been manufactured specifically for the DIY installer market.

Jordan explains that a radiant barrier is a product that is installed in the attic—between the rafters on the underside of a roof—to reduce the radiant heat gain that permeates a home when the sun is beating down on it. Radiant barrier, a particularly effective product for summer months, also reduces heat loss from a roof during the winter, which in turn reduces the workload on your furnace and lowers your heating bill.

Early, less-effective versions of radiant barriers included spray-on metallic paints, reflective radiant barrier chips or products known simply as attic foil. Installation was cumbersome, often requiring special tools, adhesives or multiple installers, and the low flash point on the older type of foil created added dangers in the event of a house fire.

It’s important to choose the best radiant barrier that is Energy Star approved and made of metalized film, not perforated aluminum foil. Today’s radiant barriers are far more sophisticated, yet some are so simple to install that no tools are required.

About Enerflex Radiant Barrier
Enerflex Radiant Barrier is an example of the best new radiant barrier technology. The product is available nationwide through a network of lumber and building materials dealers, as well as through major retailers. The product is Energy Star approved and was named one of the “Best New Products of 2010” by Professional Remodeler, a leading trade magazine.

Enerflex Radiant Barrier comes in rolls or panels, pre-cut for 16” and 24” widths for installation ease. The radiant barrier panels literally flex or “snap” into place between the rafters, with no tools needed. This makes it possible for installation to be a simple, one-person, do-it-yourself job that can be completed in a matter of hours. Watch a video on installing Enerflex radiant barrier.

Studies on installed radiant barrier products show that attic temperatures are typically reduced by a full 30 percent during the summer months, which can translate to 30 degrees on a hot summer day. In addition, the radiant barrier keeps heat from escaping from the home through the roof during the winter, so not only does your HVAC system get a break, but you can realize energy savings year-round.

Unlike the earlier versions of radiant foil barriers, Enerflex is made of a highly reflective, multilayered, metallic film that is protected by a tough poly scrim that keeps it from tearing or being punctured. The product is made in America, comes with a 15-year warranty, and has achieved a Class A/Class 1 fire rating.

In really hot climates, homeowners are finding other uses for radiant barriers. In Texas and Arizona, for example, many homeowners keep garages cool by installing radiant barrier insulation on the inside of garage doors and walls. Outbuildings on farms or ranches, or outdoor workshops can also be kept cooler in the summer when the product is installed between rafters under the roof.

Jordan of EcoRite Products says adding a radiant barrier in the cooler months makes installation safe and more comfortable for the installer.

Radiant barriers are proven environmentally friendly building materials for reducing energy bills and reducing the strain on a home’s HVAC system. And when you can spend a few hours over a weekend and complete a project that saves money month after month, it’s hard to ignore the benefits.

Both DIYer and professional installers will find installation of Enerflex Radiant Barrier products to be simple and easy—no special tools required.

As people learn how radiant barrier insulation blocks the sun’s heat to create a more comfortable and energy-efficient home, use of radiant barrier products will become more popular. With radiant barriers becoming more common in environmentally-friendly construction, additional advancements and variations will become available. Most radiant barrier products are nominally sound but they don’t match the ease of installation found with Enerflex Radiant Barrier.

No special tools required.
Unlike most radiant barrier foil, Enerflex doesn’t require prep work at all. Enerflex's metallic foil panels allow you to simply flex the panel into place between your roof joists and release. Once complete, you're ready to start saving on energy costs and high utility bills.
