Lighting accounts for a significant amount of electrical energy consumption in office buildings, up to 45% of the total consumed. This energy consumption can be reduced by as much as 60% through an occupant-dependent lighting control strategy. With particular focus on open-plan offices, where the application of this strategy is more challenging to apply due to differences in individual occupancy patterns, this paper covers (1) to which extent individual occupancy-based lighting control has been tested, (2) developed, and (3) evaluated. Search terms were defined with use of three categories, namely ‘occupancy patterns’, ‘lighting control strategy’, and ‘office’. Relevant articles were selected by a structured search through key online scientific databases and journals. The 24 studies identified as eligible were evaluated on six criteria: (1) study characteristics, (2) office characteristics, (3) lighting system characteristics, (4) lighting control design, (5) post-occupancy evaluation, and (6) conclusions, and this was used to answer the research questions. It was concluded that the strategy has not been tested yet with field studies in open-plan offices, but that it needs further development before it can be applied in these type of offices. Although lighting currently tends to be controlled at workspace level, many aspects of the strategy can be further developed; there is potential to further increase energy savings on lighting within open-plan office spaces. Individual occupancy-based lighting control requires further validation, focussing on the factors influencing its energy savings, on its cost effectiveness, and on its acceptability for users.

Responsive public spaces use interactive technologies to adapt to users and situations. This enhances the quality of the space as a public realm. However, the application of responsive technologies in spatial design is still to be explored. What exactly are the options for incorporating responsive technologies in spatial designs to improve the quality of public spaces? The book Responsive Public Spaces explores and disentangles this new assignment for designers, and presents inspiring examples. A consortium of spatial designers, interaction designers and local stakeholders, headed by the Chair of Spatial Urban Transformation of Amsterdam University of Applied Sciences, carried out a two-year practice-based study of responsive public spaces. This book draws on those insights to provide a practical approach and a roadmap for the new design process for responsive public spaces.The study results are of signi¬icance for various professional fields. The book is intended for clients and stakeholders involved in planning and design of public spaces, spatial designers, interaction designers and students.

Sensors in offices mainly measure environmental data, missing qualitative insights into office workers’ perceptions. This opens the opportunity for active individual participation in data collection. To promote reflection on office well-being while overcoming experience sampling challenges in terms of privacy, notification, and display overload, and in-the-moment data collection, we developed Click-IO. Click-IO is a tangible, privacy-sensitive, mobile experience sampling tool that collects contextual information. We evaluated Click-IO for 20-days. The system enabled real-time reflections for office workers, promoting self-awareness of their environment and well-being. Its non-digital design ensured privacy-sensitive feedback collection, while its mobility facilitated in-the-moment feedback. Based on our findings, we identify design recommendations for the evelopment of mobile experience sampling tools. Moreover, the integration of contextual data with environmental sensor data presented a more comprehensive understanding of individuals’ experiences. This research contributes to the development of experience sampling tools and sensor integration for understanding office well-being.

The Healthy Workplace monitor is being developed to monitor the health and well-being of knowledge workers in relation to the office space and their home workplace. Since the corona period, a lot has changed in the way knowledge workers work. Both offices and employees require more flexibility to carry out work in an efficient but also healthy and enjoyable way. It is important to identify office workers needs with regard to workspaces at the office and at home from a holistic view, in which mental , physical and social aspects play a role. A vital, happy employee is a productive employee.
