Comparing Green Building Certification Programs

A few weeks ago, I was asked to speak at the Arlington Chamber of Commerce about green building programs, and so I've spent some time recently thinking about and researching all the different green programs available to us in Northern Virginia. There are four programs that are the most well-known and often-used in Northern Virginia, and Arlington especially. In no particular order, they are:

 

• Home Innovation (formerly NAHB Research Center) NGBS homes
• LEED for Homes
• Earthcraft Va
• Arlington County Green Home Choice Program

 

Energy Star appliances are just one aspect
of Energy Star 3.0 certification.

Over my next few blogs, I'll talk a bit more about each of these programs, so this is just a quick overview to start us off.

 

All four programs rely on the EPA's Energy Star program in some way, shape or form. One ofArlington Designer Homes, all our homes are Energy Star certified, and it is certainly the easiest way to demonstrate that you have met a particular program's energy requirements. But because Energy Star certification is not required for Home Innovations certification, it gives the builder and homeowner more flexibility in using a variety of green features to meet certification requirements. And with all the new green building technologies available to us today, there are so many different ways to make a house more energy efficient!  All of the other programs require Energy Star certification to certify a home at a certain level. (I will talk more about Energy Star 3.0 in my next blog.)

the reasons that I like Home Innovation’s green rating system is that it allows you to certify a house without it being certified Energy Star 3.0. At

 

A solar water heater is another green feature that helps
improve energy efficiency and earn a home's green certification.

There are many more things that unite green certification programs than divide them. All of the programs mentioned above have categories covering different types of green features - you can refer to our blog from May 19^th, 2011, to review basic categories for the Home Innovations certification program (formerly NAHB Research Center). All of the programs rely on Energy Star in

some way. And most importantly, all these programs require strict third party certifications.

Arlington Designer Homes works with Kelly Ross from Kelly Green Raters to help us certify HERS energy rater to help us quantify total home energy use. Kelly uses sophisticated computer modeling to show how the house will perform and what energy savings we can anticipate over the life of our homes. Most of our homes come in with a HERS rating of close to 50. This means that we are constructing houses that are set to run on almost half as much energy as a conventionally built home.

All the major green building certification programs share the same goal - to encourage builders and homeowners to choose more efficient, sustainable ways to live. Some of these choices are as easy as switching out a light bulb. Others are more complicated, like designing a whole house energy package. Green programs offer us a map to help guide us towards more environmentally friendly alternatives and greater savings, comfort and health for our customers.
