Mr. Demetrios Moschandreas
Professor Chemical & Environmental Engineering, ITT
Chicago, Illinois
Demetrios Moschandreas, Ph.D. is a professor of Chemical and Environmental Engineering. His research endeavors focus on Risk Assessment from Exposure to multiple pollutants in multiple routes and multiple media and therefore his scientific interests include energy conservation, indoor air quality, pollution measurement and pollutant transport and fate modeling. Dr. Moschandreas has published over 150 peer reviewed papers in these areas and is a member of the International Academy of Indoor Air Sciences, a fellow of the International Society of Indoor Air Quality, and the 2002 recipient of the Wesolowski Award of the International Society for Exposure Analysis “In recognition of outstanding contributions to the knowledge and practice of human exposure assessment”. Professor Moschandreas holds post graduate degrees in Atmospheric Physics and Mathematical Statistics.
Brief description of presentation:
"How Green is Green"
The scientific literature comparing the performance of Green or Sustainable Buildings with that of conventional buildings is meager. This presentation discusses one such comparison. Five criteria define Green Buildings: (1) Sustainable building siting, (2) Energy Efficiency, (3) Water Conservation, (4) Material Selection and (5) Indoor Environmental Quality. Based on these criteria the performance difference between buildings designed to be green and corresponding conventional buildings is analyzed. This study investigated the defining criteria in all ten green buildings found in the metropolitan Chicago area. These ten green buildings were selected because they are LEED certified or registered buildings. The green buildings are compared to ten conventional buildings selected to be correspondingly similar to the LEED buildings in terms of building type and location, size, and age. The database is composed from responses to two types of questionnaires. The first questionnaire was administered to technical experts with personal involvement in the design, construction and maintenance of each building; the focus is on the first four criteria. The second questionnaire was administered to present occupants of each building; the focus is on their perception and evaluation of the first three and the last criteria. Details on the comparison of each criterion are presented. The general conclusion based on preliminary statistical analyses of the database generated indicates that the LEED buildings are not statistically different on most of the sustainable criteria. Suspected reasons for this finding are presented and discussed. |
