Owner and President
The EcoBuilders, Inc.
Rob Moody has deep roots in North Carolina. His ancestors came to the Asheville area around the turn of the last century, and Moody grew up in the home where his grandfather was born, one of three "Arts and Crafts-style, a little bit Queen Anne, a little bit shingle-style" houses his great-great-grandfather had built for the family in downtown Waynesville.
How did you get into the green-building business?
I studied biology and environmental science at UNC-Asheville, but I also grew up loving old houses because of the ones in my family. About five or six years ago, I bought the house I lived in as a child, and it needed work. I ended up doing those renovations while teaching environmental science, and the two meshed very well. I just fell in love with the whole remodeling process and I came up with the basic philosophy for the EcoBuilders during that time: a marriage of aesthetics, green building, and urban infill. In 2003, I started building my first new construction. It was the first house in North Carolina certified by the state standards for green building, which had started up the year before.
Do you do green building exclusively?
What appeals to people about green building?
Energy saving, healthier living, and doing the right thing are all important to folks; it's a very timely business right now. The market is excellent in Asheville. People have always come here for what we have to offer in terms of outdoor recreation and environmental resources, and those same things make it a green-building mecca. There's a huge market for green spec homes in Asheville too, and not enough stock to keep up with it.
What's harder to sell people on?
The guts of the house take a little more explanation. We put together a really unique system within the walls--the "lungs" of the house--with an HVAC [heating, ventilation, air-conditioning and cooling] system that works together to create a cohesive organism, really. That's where my biology training comes in! We do a fresh-air induction system, a filter system that has to work with the bath fans and the insulation, and a high-perm housewrap. You can spend more if you want to go solar, or install a greywater system, but you can build green on any budget, and in the same timeframe as other houses too.
How do you keep costs and environmental impacts down?
We emphasize tight site management: erosion control and minimizing the footprint. One way to do that is to build on piers, which can also save money on the foundation. We protect trees during construction and use native species in landscaping, and none of that costs anymore than doing it the typical way. Sometimes it can cost less.
To use resources more wisely, we frame our houses using the least amount of wood to achieve maximum stability and use 20 percent fewer studs than the traditional method. Achieving the same structural capacity while minimizing the lumber used saves money too. We also produce a fraction of the waste of a typical construction project. The key is educating our crew; it doesn’t require a lot of fancy tools.
We get insulation behind every cavity, behind the tubs, and everywhere else, so we're saving [the buyer] energy on heating and cooling. Indoor air quality is major. We minimize our use of high-VOC paints and try to use water-based polys as much as possible.
What's the most difficult aspect of building green?
For us, it's easier. We've done it from the beginning, so it would be harder not to build green. Educating homeowners and subcontractors is our biggest challenge, along with procuring materials. Lots of stuff is developed on the West Coast and is not as readily available back East, but that's changing. To do a remodel really green can be more invasive, especially if the house is lacking insulation in its walls. But we're doing a second green renovation right now, and we've done it on a pretty low budget both times.
Tell me about a challenging project you've worked on recently.
We work hard to find infill lots so we're not expanding infrastructure and contributing to sprawl, but Asheville had a huge boom 100 years ago and as one of the city officials put it: if there's a lot left in the city and there's nothing built on it, there's a reason why. It's going to be marginal in some way.
This one lot that we worked on in the historic district was a steep site, so we chose to do pier and steel-girder construction to minimize our footprint. The parking was on a concrete suspended slab, which created space below. We didn't have to bring in fill or excavate, which we want to minimize. E.O. Wilson said that when people move more earth more than ants do, that's a problem, and humans are doing that now.
We designed the house so it sits nicely and sensitively on the site. We eliminated the crawl space and basement space, pulling the whole house up to road level, which eliminates a lot of moisture issues that affect indoor air quality. We used a very efficient heat pump with natural-gas backup and employed fresh-air induction. We built a very tight [well-insulated] house, but also used a mechanical system to make sure that fresh air could get in a very measured way.
What's the one thing you wish every prospective client--or even everyone in the world--would understand about green building? Is there one decision that has the biggest impact?
It's really holistic. It's an approach, an entire philosophy. Really being open to this as a concept is the big thing, and most people are. It's a healthier house that costs less money to operate and lasts longer, so it's an easy sell. And technology is improving all the time. Solar is there and getting better, and we're seeing more and more tax benefits from going with alternative-energy use. As more and larger corporations go green--and we're really seeing a national movement in that direction--it'll just get even better.

Rob Moody also recommends visiting the websites of the U.S. Green Building Council and the National Association of Home Builders, which he says has "incorporated a fair amount of green-building standards over the last couple of years."
