Purpose:The International Commission on Illumination (CIE) recommends researchers to investigate a widevariety of behavioural and health outcomes. However, researchers often investigate only a part of occupationalhealth (OH) in relation to light. A literature study (2002–2017) regarding the relationship between office lightingconditions and OH was performed to identify gaps and methodological issues.Method:The OH outcomes investigated in this paper were grouped according to the International Classificationof Diseases and analysed per category: physical and physiological health, mental health, eye health, sleep param-eters and visual comfort.Results:Findings from the literature study (20 eligible papers) showed that all OH aspects were mostly but notexclusively measured subjectively. Furthermore, most studies investigated only a fraction of office lighting par-ameters and OH aspects.Conclusions:It seems that Correlated Colour Temperature (CCT) and illuminance mainly correlate with OH.However, this may also be explained by gaps and methodological issues in studies described in eligible papers.Based on the literature study, an overview was composed elucidating gaps and methodological issues of officelighting and OH studies. It can be used to design and target the purpose of light and health research.
Light enables us to see and perceive our environment but it also initiates effects beyond vision, such as alertness. Literature describes that at least six factors are relevant for initiating effects beyond vision. The exact relationship between these factors and alertness is not yet fully understood. In the current field study, personal lighting conditions of 62 Dutch office workers (aged 49.7 ± 11.4 years) were continuously measured and simultaneously self-reported activities and locations during the day were gathered via diaries. Each office worker participated 10 working days in spring 2017. Personal lighting conditions were interpreted based on four of the six factors (light quantity, spectrum, timing, and duration of light exposure). Large individual differences were found for the daily luminous exposures, illuminances, correlated colour temperatures, and irradiances measured with the blue sensor area of the dosimeter. The average illuminance (over all participants and all days) over the course of the day peaked three times. The analysis of the duration of light exposure demonstrated that the participants were on average only exposed to an illuminance above 1000 lx for 72 minutes per day. The interpretation of personal lighting conditions based on the four factors provides essential information since all of these factors may be relevant for initiating effects beyond vision. The findings in the current paper give first in-depth insight in the possibilities to interpret personal lighting conditions of office workers.

Sedentary behavior (SB) is prevalent in workplaces, putting office workers at an increased risk of severe health problems. To help designers and researchers gain a better understanding of office workers’ contextual concerns for physical inactivity (reducing SB and enhancing physical activity (PA)), we have proposed a conceptual framework ACTIVE4. This framework advises designers and researchers to consider four key factors that influence office workers’ physical inactivity: active mind, active behavior, active support, and active environment. We conducted three workshops (N=28 design students) to evaluate the framework. The participants found ACTIVE4 helpful in guiding them towards a more systematic understanding of the environmental influences and office workers’ personal needs for reducing physical inactivity. In future work, we will optimize the ACTIVE4 framework’s learning curve as suggested by participants and conduct an expert study to further discuss design opportunities and requirements for the ACTIVE4-related vitality toolkit.
Professionals van woningbouwcorporaties en gemeentes die zich bezig houden met verduurzaming hebben vragen over hergebruik van afvalhout uit hun (renovatie) projecten. De doelstelling van dit voorstel is het onderzoeken van de mogelijkheden om hout te hergebruiken door gebruik te maken van innovatieve digitale productietechnieken, en om implementatiestrategieën hiervoor te ontwikkelen voor publieke organisaties in de bouwsector, in het bijzonder woningcorporaties en gemeentes. Strategieën omvatten concrete voorstellen om a) afvalhout van woningen in te zamelen en te verwerken; b) waarde toe te voegen aan houtafvalstromen door middel van digitale productie; c) de betrokkenheid en acceptatie van huurders te vergroten bij circulaire verwerking van hout in nieuwe toepassingen; en d) goede toepassingen voor een circulaire economie te realiseren. Het project onderzoekt aard en omvang van houtafvalstromen uit woningrenovatie en identificeert de mogelijkheden voor het hergebruik van specifieke fracties daarvan voor (lokale) toepassingen. Uit voorgaande projecten blijkt dat digitale productie mogelijkheden biedt om stedelijk afval om te zetten in zinvolle circulaire producten. Digitale productie maakt de (lokale) creatie van unieke prototypen en grootschalige toepassingen mogelijk. Het onderzoek wordt uitgevoerd in vier werkpakketten. De eerste identificeert de aard van huishoudelijk houtafval (volume, houtsoort, verzamelproces) door zorgvuldig cases van Ymere en Rochdale te bestuderen. Daarnaast worden er een raamwerk van indicatoren gedefinieerd om projectresultaten te kunnen evalueren. Het tweede werkpakket onderzoekt welke toepassingen kunnen worden bedacht, gegeven de beschikbare houtfracties. In het derde werkpakket wordt een aantal case studies uitgevoerd voor concrete projecten van de deelnemende woningcorporaties. Deze applicaties hebben als doel het potentieel van digitale productie met houtafval te laten zien, rekening houdend met het perspectief van bewoners. Het biedt belangrijke inzichten in de uitvoerbaarheid van concrete toepassingen uit teruggewonnen hout. In het vierde werkpakket worden alle projectbevindingen gecombineerd in een set implementatie strategieën voor publieke organisaties in het stedelijk domein.
The impacts of tourism on destinations and the perceptions of local communities have been a major concern both for the industry and research in the past decades. However, tourism planning has been mainly focused on traditions that promote the increase of tourism without taking under consideration the wellbeing of both residents and visitors. To develop a more sustainable tourism model, the inclusion of local residents in tourism decision-making is vital. However, this is not always possible due to structural, economic and socio-cultural restrictions that residents face resulting to their disempowerment. This study aims to explore and interpret the formal processes around tourism decision-making and community empowerment in urban settings. The research proposes a comparative study of three urban destinations in Europe (The Hague in the Netherlands, San Sebastian in Spain and, Ioannina in Greece) that experience similar degree of tourism growth. The proposed study will use a design-based approach in order to understand tourism decision-making and what empowers or disempowers community participation within the destinations. Based on the findings of primary and secondary data, a community empowerment model will be applied in one the destinations as a pilot for resident engagement in tourism planning. The evaluation of the pilot will allow for an optimized model to be created with implications for tourism planning at a local level that can contribute to sustainable destinations that safeguard the interests of local residents and tourists.
Many companies struggle with their workplace strategy and corporate real-estate strategy, especially when they have a high percentage of knowledge workers. How to balance employee satisfaction and productivity with the cost of offices.This project focused on developing methods and tools to design customer journeys and predict the impact of investments and changes on user satisfaction with the work environment. The tools, including a game and simulation tool, allowed to focus on the needs of particular subgroups of employees while at the same time keeping an overview on the satisfaction and perceived productivity of all employees and guests. We applied Quality Function Deployment techniques to understand how needs of different types of users of (activity-based) office environments can catered for in smart customer-centric office design.
