Viktor Olgyay (Budapest, September 1, 1910-[1] Princeton (New Jersey) "Princeton (New Jersey)"), April 1970)[2]​ was a Hungarian architect and urban planner, and pioneer of bioclimatism").

He was a professor at the School of Architecture and Urban Planning at Princeton University until 1970 and a pioneer in research on the relationship between architecture and energy.

Author of numerous books, among which Arquitectura y Clima stands out. Bioclimatic design manual for architects and urban planners. This book, published in 1963 by Princeton University Press, traveled the world and trained the majority of bioclimatic architects, most of whom today are enrolled in a new architectural trend called Sustainable Architecture.

The book is the result of a compilation of eight years of research work that was financially supported by the United States Federal Housing Finance Agency, a fellowship from the Solomon R. Guggenheim Foundation, and supported by research funds from Princeton University.

In the mid-seventies of the century, the oil crisis wreaked havoc on the developed world and architects, engineers and physicists joined forces to give a different proposal to the way of designing and building in architecture. Thus the term Bioclimatic Architecture arises as a response. But in the search for antecedents they found that in the fifties the Olgyay brothers proposed a completely different architecture and successive articles and books reached their synthesis in 1962.

The first article was "The temperate house" (1951), followed by other works on "Bioclimatic Approach to Architecture" and "Solar control and orientation to meet bioclimatical requirements" (1954), a more complete edition was on "Application of climate data house design" (1954). Later, "Sol-Air orientation", "Environment and building shape" (1954) and finally "Solar control and shaiding device" (1957) emerged.

In 1967 the Rockefeller Foundation financed a sabbatical year as a visiting professor at the Faculty of Architecture of the Universidad del Valle in Cali (Colombia), where he carried out extensive project research. The first contacts began with the visit of Dean Jaime Coronel Arroyo") to Princeton and the invitation arose from that stay to "satisfy the double function of educating architects and advancing knowledge and of intertwining teaching with research."[3]​ The book summarizes the , in part 2 the and in part 3 the . This final part contains example projects carried out for Bogotá, Cali, Buenaventura "Buenaventura (Valle del Cauca)"), Guapi and Ipiales. Many of the professors and collaborators of this great experience on a country scale are prominent architects and professors in Colombia such as: Guillermo Álvarez, Silvia de Bejarano"), Eduardo de Irisarri"), Jaime Cárdenas, Edgar Erazo"), Jaime Mendoza, Leonel Osorio"), Gustavo Olguín, Jorge Santacruz"), Hugo Jurado"), among other model makers and photographers.
