Energy Vanguard's mission is to turn houses into high performance homes. We do this mainly by teaching building science and how its application can find and eliminate many of the problems in our buildings.
Our main clients are Home Energy Raters and BPI (Building Performance Institute) Building Analysts, as well as people who want to attain those or similar certifications. We focus on training and consulting, and are a RESNET accredited home energy rating (HERS) provider.
Manual J’s and D’s are an important part of what we do, and we pride ourselves providing the most accurate calculations and design possible, using the latest technologies available.
In addition, we have a broad network of certified professionals who can help builders get their homes certified in programs like ENERGY STAR. If you're a homeowner looking to find and fix the problems in your home, our network can help you, too.
Energy Vanguard began in 2008 and is actively involved in the building science community. For a more personal view of the company and what led to its creation, read The Story of Energy Vanguard, by founder Allison A. Bailes III, PhD.


Imagine a house that's comfortable; perfect temperatures, no drafts, not too humid & not too dry. Now imagine that it's built to last, so you won't be replacing rotten boards, the paint job lasts years longer than you expect, and the maintenance costs are almost nonexistent. Imagine further that it has great indoor air quality, with no moldy crawl space air or carbon monoxide from the garage infecting your lungs. Now, let's complete the fantasy and say you can have all these features and you'll pay less each month than if you'd taken the conventional house next door. Who wouldn't take that deal?!

That's really what green building is all about, and that's what Energy Vanguard can help you achieve, whether you're looking to buy, improve, build, sell, or analyze a house. At Energy Vanguard, we know houses, and we know building science. Green is not merely a buzz word or the latest fad for Energy Vanguard - It's a commitment!

We help make homes energy efficient, comfortable, durable, and healthful by working with stakeholders at all levels of the process. Here are the main ones:

Home Energy Raters, as their HERS (Home Energy Rating System) provider

Home Energy Rater candidates looking for training

Home Builders who need a Home Energy Rating to qualify a house for the ENERGY STAR label

Trade Contractors who need to understand how their trade fits into the house-as-a-system approach

Realtors wanting to learn how to sell green homes

Homeowners who want help analyzing and improving their homes

Lenders offering the Energy Efficient Mortgage (EEM) and the Energy Improvement Mortgage (EIM)


Allison A. Bailes III, PhD., President is a RESNET certified Home Energy Rating System Trainer, Home Energy Rating System Quality Assurance Designee (one of ~120 in US) and a LEED Accredited Professional (Leadership in Energy & Environmental Design) Chris Laumer-Giddens, Project Manager, is a Licensed Architect and LEED Accredited Professional (Leadership in Energy & Environmental Design)

In 2001, I bought a piece of land and spent the next two years building a green home that's beautiful, efficient, and comfortable. Having never built anything bigger than a bookcase prior to taking on this project, I had a steep learning curve in front of me—and I loved it!

After finishing the house, I became a home energy rater and left academia for my new career in the field of high performance homes. My first business was called ab3 energy, and I offered home energy ratings and building science consulting. When that turned out not to be enough to keep the business afloat, I started offering Manual J heating and cooling load calculations, and I even got into the contracting business. I did air-sealing, duct-sealing, insulation, and crawl space encapsulation to provide homeowners with a comprehensive package to improve their home’s performance.

That business was going well when life through some curve balls at me, so I ended up going to work for another home performance contractor (The Hoots Group) in Atlanta. I learned many new business and contracting skills, and then got the opportunity to work for one of the premier energy efficiency and green building organizations in the country—the Southface Energy Institute. At Southface, I started off as the regional manager for the EarthCraft House program and then also became the manager of Southface Energy Rated Homes, their HERS rating providership. Again, I learned a lot there that would have been much harder to learn on my own.

In 2008, I decided that I really wanted my own company again, so I left Southface and started Energy Vanguard. In some ways, this company is a continuation of ab3 energy, but it’s also a lot more than that. Energy Vanguard is more about teaching and less about fixing. It’s focused more on the big picture—creating markets, spreading the word (such as for Energy Efficient Mortgages), expanding networks—and less on individual components. I see this company as being on the forefront of change--the vanguard--in the way we see and use energy in our homes.

It’s been a bit of a winding path, but I’m doing what I love now and feel that I’ve finally figured out how to combine my interests, skills, experience, and education in a way that lets me serve clients to the best of my ability. The fact that Energy Vanguard is growing in a down economy is testament that I've made good choices. It's also evidence that you can succeed in this field as well. There's plenty of room for growth here.

Please let me know how Energy Vanguard can help you, whether it's with training, as your HERS rating provider, or with some other building science related need you have.
