Sustainable design for airport terminals, by integrated photovoltaic (PV) system (adopting bench-marking approach)

摘要

A huge amount of produced energy is consumed by buildings, thus architect has a significant role in reducing consumption. Public buildings with extended area and continuous operation are significant examples which if designed successfully, can be used as Bench-Mark in different constructions and climates. While sustainability focuses on energy-saving, architecture seeks to provide maximum user?s demands, which in turn, leads to a pseudo confrontation. The aim of this research is to respond to common demand of sustainability and architecture with no conflict of interest that is a rational consumption with no environmental side-effects until the concept of ?Sustainable Architecture? can be justifiable. Due to the flat area of airports, terminals are mainly subjected to direct sun-light. Therefore, airport terminals are suitable choices to implement integrated photovoltaic (PV) systems. On the other hand, preparation of electricity for these buildings which are usually away from the city, is so important. By integrated design and using moving elements of ceiling/body adjustable to sunlight, normal current and voltage are supplied and by connecting to the grid, stable balance is achieved in energy production and consumption. The results demonstrate that a major part of required energy for terminals, day and night can be supplied by radiation energy as well as solar systems. This system even performed well in highly cloudy-low radiation regions. With consideration of Bench-Marking approach in usage of PV systems in airport terminals, not only free-unlimited solar energy can be captured and substituted for pollutant fossil fuels, but also architectural demands will be provided.
