William Hajjar (1917–2000) earned his bachelor’s degree in architecture from the Carnegie Institute of Technology (now Carnegie Mellon University) in 1940 and his master’s degree from MIT in 1941. He taught at Pennsylvania State University from 1946 to about 1965. Hajjar designed over thirty buildings, mostly single-family homes, in State College, PA, with his partner Harlin J. Wall. In the early 1960s, he worked as a senior designer at Vincent Kling Architects and as design director of Harbeson, Hough, Livingston & Larsen, both in Philadelphia. In 1965, he started a career as a developer in La Jolla, CA. Robertson Ward to A. William Hajjar, 9 June 1959, and A.

N2 - In the 1950s, architect William Hajjar built a four-story research building with a two-story double-skin facade (DSF) on all four building sides with the intention to explore solar heat control strategies: in winter, the movement of warm air from sun-exposed DSFs toward the cold sides to reduce heating loads, and in summer, the removal of the DSF’s warm air to reduce cooling loads. The article presents archival studies, computational fluid dynamics simulations, and smoke experiments, all undertaken to explore the performance of four-sided DSFs with regard to heat distribution and airflow patterns in winter. The studies confirm the potentials to create a temperature equilibrium around the facade and reduce heating loads. However, excessive heat build-up in the DSFs on clear days remains challenging.
