Mitigating the negative impact of new buildings on existing buildings’ user comfort—a case study analysis

Campus master plans are released every few years for developing and implementing its physical infrastructure. Open spaces, compactness, connectivity, greenness, and environmental impact have often been the focus on its framework. In particular, the effect of new building development on existing buildings’ occupant comfort and design intent is mostly ignored. Providing guidelines to retain existing users’ comfort for stakeholders involved in design decision making will result in improved design decisions. Hence, this research aims to provide a work methodology to mitigate the adverse effects of new buildings on existing buildings’ user comfort through a case study at Carleton University. The case study shows a methodology to retain the existing users’ comfort by analyzing Carleton University’s master plan on massing studies, occupant survey to understand their comfort needs, performance analysis of the impact of the new building on the existing building user comfort. The analysis reveals the key parameters to consider in design for occupants’ comfort. Finally, the research reinforces the generative design and the need for dynamic modeling in campus master plans to mitigate the negative implications of new development on occupants’ comfort.
