- Abstract
- The influence of fenestration design on energy performance and illumination conditions in office and residential buildings is examined, and recommendations are given for effective design of fenestration systems to meet occupant requirements. Particular emphasis is given to various shading strategies, such as blinds, shades, light shelves and fins, and their impacts on interior daylight levels and distribution, illumination quality, and energy requirements. A comparison is made between the total daylight gain into the building and the useful daylight gain, where useful daylight is defined as daylight which can be used to offset electric lighting requirements. Significant improvements in daylighting, lighting and thermal performance are shown to be possible with various fenestration designs.
