Glass in Architecture : Design and Knowledge of Function

There are various theories about the origin of glass. One is that glass beads were made during the time of the Old Kingdom in Egypt (27th-22nd century BC). Another suggests that glass was first manufactured around 18th-17th century BC. The truth is uncertain. Without a doubt, however, glass has been a notable feature of a great deal of architecture, most notably the Crystal Palace which was built on the grounds of the first World Exposition, held in Hyde Park, London, in 1851. It was an enormous building made from an iron frame work and glass. The theme of this paper is the continuing evolution of glass architecture. It discusses design, and plans which make full use of state-of-the-art technology to achieve energy conservation. Here, the term "glass architecture" refers to buildings whose outer walls and roofs are mainly or entirely made of glass. The distinguishing features of glass architecture can be described as follows: (1) In glass architecture, the aim is to bring more light into the building, and thereby create building with a healthy environment and outstanding occupant comfort, which prevents people from getting sick. This can be achieved by skillfully using natural conditions such as light and heat. (2) Transparent architecture allows people to see the sunny sky on clear days, and the cloudy sky when it is overcast. Sunshades are indispensable fixtures which enable adjustment of light and heat. (3) Glass architecture is the starting point for greenhouses, and the standard practice is to investigate greenhouses first when looking at design and functions such as ventilation or the heat/light environment. (4) If intelligent design and function are built in, then it is possible to construct glass architecture with outstanding occupant comfort, and low overhead thanks to energy conservation. (5) Since there are too many types of glass, and this makes things difficult to understand, a classification is used which combines the glass manufacturing process and sunshades.8KJ00005217966研究ノートStudy Notedepartmental bulletin pape
