Abstract

Green construction is a way of planning and managing construction projects to minimise the impact of the construction process on the environment so that there is a balance between environmental capabilities and human needs for current and future generations. Appropriate Land Use (ASD), Energy Efficiency and Conservation (EFC), Water Conservation (WAC), Material Sources and Cycles (MRC), Air Quality and Space Comfort (IHC), and Building Environmental Management (BEM) are six guidelines for evaluating green building assessments. These are used as a benchmark for green buildings; a check is carried out to determine the rating of the building. The evaluation is carried out by distributing questionnaires. The data is processed using the Fuzzy method through the Matlab application, which refers to the Greenship 1.2. The results showed that the calculation analysis with the help of MS Excel and modelling with a fuzzy system in the Matlab application gave the same predicate results. Validation of modelling results with case studies on Building Projects in Malang City showed Bronze predicates with a total index of 44 Points and Silver predicates with a complete index of 57 Points.
