Abstract:
The focus of this research is the enhancement of daylighting design in office buildings and the
lowering of energy consumption. This study systematically explores and analyzes the visual
performance of two different prototypical office layouts through the case studies selected in Tirana.
The sensitivity of total energy use due to orientation, window area, glazing properties (U-value,
visible transmittance), shading system is described.
The research approach is conducted through lighting simulation software and face-to-face
questionnaires. For each office building the actual conditions are firstly analyzed, and then, different
other options are provided. The findings from this study provide evidence of the problems of daylight
and artificial lighting problems and especially workers´ performance difficulties related to lighting
conditions. Thus, recommended solutions, which try to optimize daylighting design, to enhance
workers´ productivity and to lower energy consumption, are provided.
