Optimization of Atrium Geometry in an Office Building in Terms of Daylighting - a Case Study

Abstract

Abstract The importance of daylighting in the design of microclimate for work and living spaces. Legislation and legislative requirements for daylighting and combined lighting of workspaces in Slovakia. Theoretical analysis of physical determinants affecting the function, geometrical design, and location of atria in buildings in terms of optimizing the light comfort in work and relax spaces. Exterior atria and their dimensions considering the boundary conditions of the site. Optimizing atria geometry depending on its function and location in terms of daylight distribution. Influence of the atrium height and self-shading on the daylight distribution in workspaces. Daylight intensity and evenness in the offices with windows facing exterior atria - model solutions. Designing atrium geometry for an office building considering microclimate optimization and light comfort in spaces for work and relax in terms of safety and energy efficiency - a solution example.
