Daylight utilisation potentials of highly glazed individual office spaces in Belgrade climate condition

ABSTRACT
Office buildings have high standards for lighting requirements, which greatly contribute to high lighting energy consumption. Daylight utilisation is one of the means to reduce it. The goal of this paper is to evaluate daylight utilisation potentials in Belgrade climate in order to generate initial design guideline for highly glazed small, individual office spaces. Daylight availability and its lighting energy implications are analyzed using computer simulation tool DIVA for Rhino. Selected individual office space is modelled as a narrow rectangular space, sidelit and highly glazed. Parametric analysis was carried out for: (a) four different glazing ratios (50%, 60% 70% and 85%), (b) four glazing types with different visible transmittance properties (80%, 72%, 62% and 54%) and (c) four different major orientations. Since this analysis is evaluating daylight utilisation potentials, no shades or external obstructions were considered. The major results of this study indicate high potential for daylight utilisation in office buildings in Belgrade. Daylight utilisation in single offices is reaching its maksimum in model with 70% window-to-wall ratio for all office orientations except north orientation, where daylight utilisation is reaching its maximum at maximum window-to-wall ratio. Also, north orientated spaces have highest benefits from utilisation of useful diffuse daylight. Direct sunlight and size and shape of facade aperture above working plane are determining factors for utilisation of daylight in office spaces.
