As construction activity continues to grow worldwide, encompassing new building projects and the revitalization of real estate and infrastructure, it becomes increasingly crucial to prioritize sustainability, citizen-friendliness, and long-term economic viability. Utilizing tools for assessing the potential impact of choosing one building variant over another, especially during the initial planning stages, can significantly contribute to achieving these goals. The Holistic Quality Model (HQM) outlined here, designed for evaluating building options, incorporates economic, technical, environmental, and social considerations from the outset. This paper primarily aims to foster an understanding of the economic quality aspects within the construction process and to elucidate the development process of the multi-parametric HQM. Additionally, it presents the most recent findings regarding the current relevance of specific economic quality characteristics for decision-making among various building client groups (e.g., industrial companies, public authorities, etc.), offering valuable insights into prevalent considerations and decision-making practices in the construction industry.
