Who is 'smarter', humans or buildings?

Abstract

Given the building sector's significant impact on energy consumption and CO2 emissions, there is a clear need for a sustainable solution. Here, smart building technologies are emerging as a promising response, as they offer the potential to improve operational efficiency while reducing environmental impact. However, the development of smart building solutions for the building sector often follows a technology-driven approach, in which technical feasibility and overall system optimization are prioritized over occupants’ perspectives, preferences, and behavior. As a result, building systems and technologies are not fully aligned with how occupants use and interact with these spaces. Bridging the gap between theoretical knowledge and practical application is, therefore, crucial for unlocking the full potential of smart building technology.

This study focused on enhancing our understanding of the interaction between smart building technology and users. A specific focus is placed on climate control technology within the broader landscape of smart building systems. By employing an exploratory approach, in which a combination of qualitative and quantitative methods was utilized, smart building users’ preferences and behavioral mechanisms were explored. Through semi-structured interviews with smart building occupants, the study delved deeper into understanding the motivations, barriers, and other aspects of occupant behavior and interactions with smart building technology. Additionally, insights from interviews with industry experts provided valuable perspectives on which key factors contribute to the increased adoption of smart building technology. These qualitative findings were complemented by quantitative data collected through an online survey (n=92), which allowed trends and preferences to be identified from a larger group of smart building occupants.

The study showed that the successful implementation of smart building technology goes beyond mere technological details. It provided empirical insights into the preferences and behavioral mechanisms of smart building occupants, filling a gap in the existing literature. By exploring these aspects, the research deepened our understanding of user interactions within smart buildings. Consequently, it advocates for a user-centered approach to smart building initiatives, emphasizing the importance of understanding human preferences and incorporating user feedback to effectively adapt technology to their specific needs and routines. However, the study revealed a diverse range of user preferences and motivations regarding interaction with smart building technology, including preferences regarding control levels, system feedback, transparency, flexibility, and interface design. This diversity highlighted the absence of a one-size-fits-all approach to implementing smart building technology. Consequently, specific practical recommendations were developed to guide stakeholders in smart building initiatives, emphasizing a more user-centered implementation that ensures adaptability to the unique needs and preferences of building users.
