Early Projects, 1978-1988:

During his internship from 1974-1977 with several Asheville area firms , Mr. Langdon taught sustainable design courses at Asheville-Buncombe Technical College, and at Warren Wilson College. By the time he opened his own firm in 1978, he already had a series of passive solar projects underway. During 1978-81 he traveled widely, teaching Energy-Efficient Shelter and Solar Design at Goddard College in Vermont, editing in Philadelphia The First Passive Solar Home Awards Book, and combing the United States from coast to coast for his own book, Movable Insulation, published by Rodale Press in 1980.

During the years from 1978 to 1985, much of the work of the firm was in the design of passive solar or sustainable homes. With each passive solar home that we designed for the Asheville area, we would continually demonstrate new ways of assembling living space with strategically placed glass and thermal mass for maximum wintertime passive solar gains. The houses often included attached sunspaces, direct gain windows, interior mass walls, variations of indirect gain such as the modified Trombe wall and other heat storing elements such as water-filled tubes or phase-change cylinders. Super-insulation and air heat recovery systems will be found in some of these projects as well.

While our work during this period was focused strongly on energy and design, it included a range of other project types, including commercial work, apartments, dormitories, historic preservation, and adaptive building retrofits.

During 1983 and 1984 Mr. Langdon was a Visiting Assistant Professor of Architecture at the University of Arkansas, where he jointly taught studio with the world renown, E. Fay Jones, FAIA and AIA gold medalist. This return to the studio as a design faculty in the collegiate architecture school setting, brought Mr. Langdon back into the study of the interface of many complex architectural and urban design issues.

Mr. Langdon returned to private practice in Asheville in 1985 with an interest in broadening the work of the firm to virtually all project types. The late 80's saw a mix of commercial and residential projects. By the 1990's, the firms work was mostly commercial projects, along with some significant public commissions.
