A decision support mechanism for LEED building design & construction: Transit stations

Leadership in Energy and Environment Design (LEED) is one of the most known and widely preferred green building certificate that is provided by the United States Green Building Council (USGBC). Among the several certificate types of LEED, the most recent one is LEED Building Design and Construction: Transit Stations (LEED BD+C: TS), published in order to meet the requirements of transit stations with the valuable input obtained from the metro corporations in India and China. LEED BD+C: TS leads to a complicated decision process that requires multidisciplinary collaboration during decision making process, technical expertise and experience of the decision makers, and investment assessment. In this paper, a decision support mechanism is suggested for such decisionmaking process. This decision support mechanism utilizes Analytic Hierarchy Process Ranking method, aiming to provide an insight for the decision makers to choose the most efficient LEED credit alternatives in terms of LEED Certification achievement. The proposed decision support system will be tested on a metro station construction in Istanbul Turkey that the first Author has professional experience on, as a case study.
