Passive solar living spaceMr. Crenshaw has devoted himself to an architecture that protects the environment and responds to the psychological, physical and financial needs of his clients. He does this through programming, developing behavior patterns, site analysis, and working closely with the trades people.

A turtle has a shell and we have houses. A house can be a support system that sustains us both psychologically and physically. This is where my Architectural Practice begins. When you look around your house I want it to be a joy; when you put something away, I want you to have a place to put it; when you need something, I want you to be able to find it. My tools are carpenters, plumbers, electricians and other tradesmen. I want to take care of them and be closely connected to them in order to save time and money and still build a quality home. My practice is not about building the most space for the least money but about building good quality usable space at a minimum cost.

village centerAfter his graduation from architecture school, Mr. Crenshaw worked in architectural offices and on construction sites. During this time, he worked as a draftsman, designer, job captain, carpenter and general contractor. He worked on houses, office buildings, apartments, dormitories, hotels, shopping centers, and churches. Mr. Crenshaw designed a group of inexpensive townhouses in Reston, Virginia and acted as general contractor in the remodeling of a house in Georgetown, in Washington D.C. In 1966, he became an associate in the firm of Douglas Stenhouse and Associates. In 1969, he worked as a design consultant to Mark Beck and Associates where he dealt with architectural programming and energy analysis. In this capacity he developed a building program and a design for a Builder’s Solar House and worked on the Department of Energy’s (DOE) Solar Data Network.

neighborhood centerMr. Crenshaw worked at the Rouse Company as project coordinator for village and neighborhood centers in the new town of Columbia, Maryland. He was responsible for evaluating proposed building sites, developing building programs, budgeting, and coordinating the work of the architects and contractors. At neighborhood centers he carried the additional responsibility of directing two draftsmen in the preparation of design drawings, working drawings, and specifications.

He worked on Operation Breakthrough (industrialized housing) developing the PBS Performance Specifications for Office Buildings, a performance version of the Minimum Property Standards, performance guidelines for evaluating the design of housing sites, performance specifications for windows, solar energy, and energy conservation. His work in energy began with performance specifications for active and passive solar buildings. Following that work, he located funding at the Community Services Administration (CSA), organized and managed a $3 million (dollar) demonstration of energy conservation in low-income housing and spent two and a half years managing this project which involved contracting, budgeting, data processing and coordinating people at 12 sites across the U.S. The project conclusively demonstrated to a Congressional panel that, for an investment of $1,700, the energy consumption in existing houses could be reduced by an average of 40%. The cost data collected was used as input to an energy consumption computer model CIRA developed at Lawrence Berkeley Laboratory and then the consumption data was used to validate the program. As part of this demonstration, data was also collected on infiltration, mechanical systems efficiencies, air quality, temperature stratification, and comfort.

Mr. Crenshaw worked at the Lawrence Berkley Laboratory (LBL) as Deputy Program Leader for the Energy Efficient Building Program (EEB). EEB was an $8 million (dollar), 100 person research program consisting of five subprograms devoted to research on infiltration, daylight, windows, lighting, indoor air quality, conductive heat transfer data and computer modeling (DOE-2). His work there was concerned with planning, contracts, budgets, personnel, space allocation, and review of publications. He was also able to continue his research on comparing calculated and measured data on energy use in houses.

Grad studentMr. Crenshaw was an Associate Professor in the School of Architecture at Florida A & M University. He taught both Environmental Technology and Design. In Environmental Technology, he taught a series of three courses beginning with a course on comfort, passive heating and cooling and HVAC; going on to a course on day lighting, lighting, electricity, acoustics and indoor air quality; and finally ending with a course on field measurement. In the final course, actual buildings were measured, evaluated and recommendations were made for their improvement. Along with this series of courses there were laboratory sessions. In the Labs, Mr. Crenshaw instructed students on how to evaluate the thermal and day lighting aspects of their designs. They did heat load calculations, ran computer energy simulation programs, created light distribution curves for lighting fixtures designed by students, and made daylight measurements of student’s models both outside and in a 10’ x 10’ indoor artificial sky. In the design studio he focused a great deal of attention to the detail use of buildings and their sites and to the use of environmental technology as a Building Form generator.

Mr. Crenshaw’s home in Maryland has been part of the ASES National Tour of Solar Homes for the last 10 years. He has written numerous papers on energy conservation and won the education award from Los Angeles American Planning Association for organizing and editing the book Sustainable Cities, published in 1993 and used by many universities as a textbook for sustainable design.
