Abstract

This study investigates solar shading in the context of commercial buildings. The motivation behind this research is to examine, if the inclusion of solar shading into building design can assist in the comfort of the users who occupy these buildings and to investigate can the incorporation of a solar shading system aid in the reduction of expenditure on mechanical cooling. In order to assess this, an examination has been carried out on published information regarding relevant aspects of solar shading encompassing the effects of solar gain on buildings (i.e. solar glare and heat gain), the impact on users of buildings and the possible reduction in reliance on air conditioning. An analysis of how such an assessment would take place through sun paths and glazing transmittance has been discussed. The various shading techniques possible have been outlined, followed by an examination of differing control methods and their application. In order to quantify shading and glazing transmittance an assessment of the g-value is outlined with the relevant pre-determined tables. A cost benefit analysis is included to discuss the cost implications of including a shading system and the reduction in expenditure on air conditioning from previous studies is outlined. The conclusions of this research are that shading systems have a definite role to play in achieving an environmentally sound building; however, every building will require differing analysis to uncover the most applicable shading and control system for the subject building.
