The study investigates how an existing warehouse located in Denmark could be transformed into a modern office and innovation center through a pragmatic, context-sensitive design approach. The objective was to demonstrate how reusing structures, optimizing natural resources such as daylight, and prioritizing human comfort to create a sustainable, future-ready workplace while preserving architectural heritage. Daylight analysis informed the placement of roof- and facade windows, addressing both regulatory requirements, such as the Danish Building Requirement [1] and the European standard EN 17037 [2]. The daylight autonomy level reaches 300 lux or more over 65% of the space for at least 50% of the yearly daylight hours. Apart from a grid-based daylight evaluation of the mandatory Danish daylight requirements [1], the evaluation contains an in-depth evaluation of how the daylight affects human vitality, comfort and emotion, diving deeper into health, comfort, and well-being potential to model a building occupant’s ‘day in the life’. An external collaboration partner employed a custom simulation-based workflow to simulate eye-level light exposure over the course of a typical day and assessed the impact of window and roof openings on circadian health potential. A simulation was used to quantify equivalent melanopic lux (EML) [3] received at eye level under clear and overcast sky conditions throughout the day [4, 5]. This data was then used to ‘unroll’ an occupant pathway and compare the impacts of design decisions on hourly and seasonal variations. A lack of adequate eye-level light exposure during the day can adversely affect well-being over time, influencing melatonin production, mood, and immune response, while sufficient exposure to light at the right time can enhance alertness and promote better sleep [6, 7]. In this context, daylight was assessed from an occupant’s perspective within the space rather than based solely on daylight reaching a horizontal plane.
