Contribution of daylight to employees in terms of health, productivity, and overall wellness in the office spaces are undeniable. Apart from the psychological and biological benefits of employees, embracing daylight in office spaces increases the energy-efficiency of the building which leads to the sustainable development of a city. However, a considerable number of employees in Sweden lack daylight in their workspaces according to a report by the Swedish Work Environment Authority [Arbetsmiljöverket (Swedish)] (Lowden, 2019). Professionals like Architects, Lighting Designers, and students of architecture and lighting design across Sweden were asked their opinions pertaining to lack of daylight in a considerable number of office spaces in Sweden based on their experience through online questionnaires/ interviews to get to know the overview of this subject. Out of all the possible reasons, window design and economy were the two macro factors according to them that influenced daylight in an office building in Sweden but often, obstruction angle in a building due to urban densification is overlooked when it comes to daylight in an office building. This thesis discusses the influence of obstruction angles with an illustrated office building in Stockholm. Diva for Rhino was the software used for the modelling and daylight simulation.
