Evaluating the life cycle of buildings is a priceless software for assessing sustainability and analyzing environmental penalties all through the development operations of buildings. On this research, with a view to decide the significance of constructing life cycle analysis indicators, a brand new mixture technique was used primarily based on a quantitative-qualitative technique (QQM) and a simplified best-worst technique (SBWM). The SBWM technique was used as a result of it simplifies BWM calculations and doesn’t require fixing advanced mathematical fashions. Decreasing the time required to carry out calculations and eliminating the necessity for sophisticated pc software program are among the many benefits of the proposed technique. The QQM technique has additionally been used on account of its potential to judge quantitative and qualitative standards concurrently. The feasibility and applicability of the SBWM have been examined utilizing three numerical examples and a case research, and the outcomes have been evaluated. The outcomes of the case research confirmed that the factors of the estimated value, consolation degree, and primary ground space have been, so as, an important standards among the many others. The outcomes of the numerical examples and the case research confirmed that the proposed technique had a decrease complete deviation (TD) in comparison with the essential BWM. Sensitivity evaluation outcomes additionally confirmed that the proposed strategy has a excessive diploma of robustness for rating and weighting standards.
