A Framework to Integrate Universal Design Standards and Generative Design for Designing Age-in-Place Houses at the Conceptual Stage

While the global population is aging, the construction industry is increasingly facing challenges in addressing the demand of designing and constructing comfortable and adaptable houses to allow Canadians to stay in their familiar surroundings. This research introduces an innovative approach to develop a model that combines Building Information Modeling (BIM) and Generative Design (GD) principles to address the aforementioned issue and explores the benefit of enhancing BIM tools by integrating Universal Design (UD) standards with GD. The said model utilizes a comprehensive database based on guidelines and standards related to UD, Accessible Design (AD), and barrier-free design (BFD) seamlessly integrated into a BIM environment. This integration is one step toward a full digitalization of the codes and standards that will allow automatic access and incorporation of diverse design standards, ensuring a holistic and inclusive design approach. Furthermore, incorporating GD would add a dynamic dimension to the process, empowering designers to create multiple design options for floor plans tailored to specific standards and individual needs. This paper presents a methodology for this integration, highlighting its potential to transform the early design stages, promoting adaptability, and solutions that prioritize the needs of residents while developing age-in-place houses. The proposed framework offers a compelling alternative to enhance the quality of life for Canadian seniors while contributing to attaining more sustainable and cost-effective options for housing.
