| Summary: | A construction assessment system is needed to determine the relationship between green construction and sustainable development aspects. The green construction assessment model developed by Ervianto has not been able to accommodate the nature of human judgment, which reflects the concept of fuzziness, in the form of linguistic values. The development of a model with fuzzy logic to solve the problem of human subjective assessment has been carried out, but the fuzzy model has not been able to accommodate the fuzzy assessment of input data in the form of linguistic variables. The purpose of this research is to develop an assessment of green construction models in the building construction process in Indonesia which is manifested in the form of instruments based on the fuzzy analytical hierarchy process approach, which can accommodate vague assessments in the assessment process as well as data input. The research was carried out in four stages, namely the hierarchy modification and questionnaire preparation stage, data collection using a questionnaire with the principle of comparative judgment to obtain green construction assessment preference data from academic and construction practitioner respondents, forming of the FAHP model, and model validation by comparing the results of model trials with Ervianto model. This research has succeeded in developing the FAHP Green Construction Assessment model which is embodied in a self-assessment instrument for each construction activity or project. This model can accommodate vague assessments in the assessment process and input data. Mathematically, the FAHP model can be said to be superior to the previous model because using a simpler number of calculations (less number of main indicators with the same number of hierarchical levels), the model is able to produce the same results. However, the resulting final green construction value is very sensitive to the set of valuation categories used, because the set determines the assessment standards used.
