Dr. Treado is a Mechanical Engineer in the Building Environment Division, involved inlaboratory and field testing, along with computer an analytical studies, related to building thermal and energy performance. He first came to the Center for Building Technology as a summer student in 1973, and returned following graduation in 1974. His current research activities include developing and refining test procedures for lighting and plumbing equipment in support of the DOE Appliance Standards program. He also developed and executed a detailed evaluation of the NIST ATL Temperature Control Module, including verification of thermal conditions and control system performance. His research activities include lighting and HVAC system performance, lighting test procedures, the measurement and modeling of the interactions between lighting and HVAC systems, and illumination conditions and task visibility. He has developed, built and operated a test facility for studying the interactions and illumination conditions, and a laboratory for lighting component interactions. Other research activities have involved the role and impact of fenestration on building energy performance. He has developed and operated the NBS Daylight Laboratory to evaluate the daylighting effects of fenestration systems, and dynamic sky conditions. He has developed a state-of-the-art automated microcomputer data acquisition and analysis system, which is used to process a large array of measurement parameters on a continuos basis, and designed and built a window calorimeter. The NBS Daylight Availability Database has been published based on these measurement data. In carrying out his duties as project leader, he prepares proposals, develops the experimental plans, designs, constructs and installs experimental apparatus and equipment, collects, reduces and analyzes data, and prepares technical reports describing the results. The results of his technical work have been incorporated into IES recommended practices for daylighting design, GSA guidelines for solar shading system utilization and ASHRAE standards for measurement of the solar-optical properties of materials, as well as the ASHRAE Handbook of Fundamentals, and the IES Lighting Handbook. He has presented the results of his work to national organizations such as ASHRAE and the Illuminating Engineering Society (IES), and has published over 50 papers in the technical literature. He is a member of IES and participates on the IES Daylighting Committee and Testing Procedures Committee, and is an associate member of ASHRAE, and a member of TC 4.5 Fenestration Committee. He was awarded the Taylor Technical Talent Award for outstanding applications paper by IES in 1992, and the 1995 Crosby Field Award for the best ASHRAE paper published in 1994. |
