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:
- 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.
- 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.
- 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.
