In a groundbreaking study that bridges the gap between architecture and neuroscience, researchers have uncovered how residential spaces influence our emotions, both psychologically and physiologically. Led by Carmen Llinares of the Universitat Politècnica de València, the study, published in *Vitruvio: International Journal of Architectural Technology and Sustainability* (which translates to *Vitruvius: International Journal of Architectural Technology and Sustainability*), offers a fresh perspective on how homes can be designed to enhance well-being.
The research, conducted in a fully equipped dwelling, involved 30 participants who navigated through various rooms under both daytime and nighttime conditions. Their emotional responses were measured using the PAD model (pleasure, arousal, dominance) and physiological signals, including electroencephalogram (EEG), heart rate variability (HRV), and electrodermal activity (EDA). The findings revealed statistically significant differences across rooms, time of day, and gender.
Collective areas like living rooms and entrance forecourts were associated with higher levels of pleasure and dominance and lower physiological activation. In contrast, individual spaces such as bedrooms and bathrooms elicited higher physiological activity and lower psychological emotional responses, particularly among female participants. This suggests that the design of these spaces could be optimized to better support emotional well-being.
One of the most intriguing findings was the inverse relationship between pleasure/dominance and physiological activation. “This suggests that physiological indicators could serve as non-intrusive proxies for subjective well-being,” Llinares explained. This insight could revolutionize how architects and designers evaluate the emotional impact of their work, potentially leading to more emotionally supportive residential environments.
The study also highlighted the impact of nighttime exposure, which was linked to increased arousal, likely due to circadian disruption caused by artificial lighting. This finding has significant implications for the energy sector, particularly in the development of smart lighting solutions that mimic natural light patterns. By integrating these insights, designers could create homes that not only look good but also promote better sleep and overall well-being.
The commercial potential of this research is vast. Homebuilders, interior designers, and technology companies could leverage these findings to create products and services that cater to the emotional needs of residents. For instance, smart home systems could be programmed to adjust lighting and ambient conditions based on the time of day and the specific emotional responses of the occupants.
As Llinares noted, “The integration of objective and subjective measures in architectural evaluations offers actionable insights for the design of emotionally supportive residential environments.” This research not only paves the way for more emotionally intelligent design but also underscores the importance of interdisciplinary collaboration in shaping the future of residential architecture.
In the broader context, this study could influence the development of new standards and guidelines for residential design, ensuring that homes are not just functional but also emotionally supportive. As the field of neuroarchitecture continues to evolve, we can expect to see more innovative solutions that prioritize the well-being of residents, ultimately leading to healthier, happier living environments.
