Integration of a methodology using digital technologies for sustainability assessment in decision making about water management building system

Water scarcity, especially the availability of potable water, is exacerbated by global warming and poses a significant challenge. The construction industry significantly impacts water usage, prompting the development of certifications and standards aimed at mitigating buildings' environmental impact. The thesis examines the green building concept with a focus on water conservation, utilizing Building Information Modeling to analyze this concept within the framework of sustainability by following the LEED certification system. Despite efforts to quantify sustainable buildings clearly, the complexity of sustainability and its assessment presents challenges. Integrating BIM and LEED as a framework for green certifications, this study develops a methodology in the Visual Programming Language. This methodology, created in Dynamo for BIM modeling software, aims to simplify assessment parameters and calculations and assist users in selecting appropriate strategies and parameters to acquire credits. A conceptual model of a case study building was developed to be analyzed using various indoor water-consuming fixtures and outdoor landscaping choices. The study calculated and analyzed both indoor and outdoor potable water usage, demonstrating that strategic design decisions can significantly conserve water. For validation, a comparative study was conducted across three scenarios, providing informative charts, monthly water consumption statistics, and reduction percentages. This integrated approach facilitates the decision-making process for achieving certification and water saving solutions, thus saving considerable time and resources.
