COMPREHENSIVE OPTIMIZATION SYSTEMS AND METHODS FOR WHOLE LIFECYCLE CARBON MANAGEMENT AND CIRCULARITY PLANNING OF EXISTING AND NEW BUILDINGS THROUGH MULTI-CRITERIA SIMULATIONS AND ANALYSES

Provided are methodologies to improve the recovery of building materials at end-of-life (EoL). The methodologies provide a decision support tool incorporating the main factors that impact the value of materials in buildings and employs a multi-objective optimization model to estimate optimal EoL options for materials. The impact of regional factors can be assessed. The methodologies are aimed at evaluating circular design and construction strategies. A first method includes selecting building strategies, inputting building information, generating simulations of design scenarios based on a generated building model, analyzing the design scenarios to determine at least one optimal design, by analyzing the design scenarios with multi-objective optimization methods, analyzing the salvage estimation of the design scenarios, performing an optimization to generate salvage objective tradeoff curve, analyzing each building material for EoL possibilities using the optimization, and performing a sensitivity analysis to validate the EoL possibilities and to analyze an optimization framework.
