I wrote this article on the use of pre-air conditioning techniques in regional architecture of the South by a very busy, respected firm in Atlanta. The story will run in the January 2011 edition of Green Building + Design, where I am a regular contributor. As a writer on green topics, I find that so many of the ideas of today respect the designers and builders of the past:

The classical, traditional designs of the American South are surprisingly green. How so? To begin with, the architects and builders who were responsible for constructing handsome homes and other structures in the 18th, 19th and early 20th centuries didn’t have mechanical air conditioning to provide relief from a hot, humid climate.
“Traditional design is light-years ahead of understanding and promoting sustainability, compared to modernist contemporaries,” says Kevin P. Clark, LEED AP Partner with Historical Concepts, an architectural, planning and “place-making” firm based in Atlanta. “At its root, traditional architecture strives to use locally sourced materials, constructed in a way that is inherent to their nature and configured to be respondent to the site’s climate and culture.”
The firm’s work reflects many of the philosophies of Original Green from Steve and Wanda Mouzon (New Urban Guild, Miami), who promote “the design of true traditional buildings and places native to and inspired by the regions in which they are built.” They are averse to “gizmo green,” the use of technologies when a broader, more holistic approach to sustainability can often draw from what builders knew hundreds of years ago.
A good example is from Historical Concepts’ 2,300-square-foot Idea Cottage, situated in the Charleston, SC-area low-country, new urbanist village of I’On that is recognized for its smart growth features. Featured in Coastal Living magazine for its ability to “live large in a small footprint,” the home achieved LEED Gold certification–even without solar collectors in this sunny locale.
“In-town lots preclude perfect solar orientation,” says Clark. “Besides, solar panels take a lot of energy to construct.” Instead, this beach-style, canal-fronted home achieves sustainability through other features:
- Narrow structure that allows cross ventilation in all rooms
- Tankless water heaters
- Pervious paving in a side courtyard
- Light-imprint driveway
- Cork flooring
- Locally sourced woods and other materials
- No carpets (and no formaldehydes)
- Polyisocyanurate insulation
- High-efficiency heating and cooling systems
- Tight walls and roofs
- Dehumidification with fresh air intake
- Deep overhangs that shade from summer sun
- Transom windows to optimize breezes and shared light to interior spaces
“This shows that a house doesn’t have to ‘look green,’” says Elizabeth Dillon, a LEED AP architectural designer with the firm. Instead, the house and the village itself meet many of the expectations of Original Green. These include accessibility, where the car is but one option for getting around town, and lovability, where the home is so well-designed that future generations will appreciate it as much as those who built it.
Dillon offers the traditional southern courtyard as a clear feature of sustainability. “Plants and water features in the courtyard create an evaporative cooling effect,” she notes. Raised garden beds, whose walls add seating to living and dining furniture arrangements, border the Idea Cottage courtyard. Plantings between pavers further soften the hardscape.
Historical Concepts practices sustainable design it its broader applications, that of planning and place-making.
Examples of these include an engagement with the historic town of Senoia, Georgia. Located an hour outside Atlanta and faced with encroaching development, the city planner contacted Historical Concepts in 2005 to conduct a historic precedent analysis, create imagery and character sketches, develop conceptual architecture and streetscapes and write a design guidelines to protect and enhance its historic district.
The firm performed similar functions for the Fairburn (Georgia) Education Campus, a historic infill site intended to make education accessible to local citizens while serving as a catalyst to commercial investment in the community.
With so much inventory of pre-20th century towns and buildings in the South, it is smart business for the firm to focus its work on this aesthetic. And clearly, there are plenty of opportunities to achieve sustainability by either working with existing structures, or building new in a compatible style that works smartly in this region’s climate.
“Historical structures are much more attentive to human scale and proportions,” says Dillon. The compact nature of historic downtowns the firm helps preserve were clearly built on this scale as well.
These are features that lead the firm’s architects to be bullish about the future. “Younger people grew up in suburbs and now yearn for a more vibrant lifestyle, less slaves to cars,” says Clark. “They want mixed-use, diverse, walkable neighborhoods where they can invest care and love into their homes. Unlike in the past, people now want one community where they can stay for years.”
It is hard to imagine why anyone would ever choose to leave a coastal cottage like the one Historical Concepts designed in I’On.
