Abstract
Contemporary office buildings are frequently designed with curtain wall systems that inevitably allow enormous amounts of direct sunlight. This fact has several negative effects on the work environment and as a result, from an energy usage point of view, most of today's curtain wall buildings use certain shading devices to keep a comfortable work environment. Among many shading devices, perforated aluminum panels have often been used as an esthetical respond to popular High-tech and Neo Modern style architecture since the early 1980's but their functional effectiveness has been not seriously examined. This study compared luminous environments in office buildings with illuminance and luminance values between several perforated panels and fabric roller shades, which are the most widely used shading devices. This study creates a new functional standard for perforated panels and demonstrates their value not only in style but also as a reliable shading device.
