Introducing an Innovative Variable Building Layers System (V.B.L.S)

Architectural Survey in recent decades shows that the modern architecture has not been considered compatible with climatic conditions and it not only causes Environmental pollution but also increases cooling and heating costs. Nowadays architects are looking for appropriate solutions to design buildings that can be in harmony with their environment and climate. As there are different seasons and days in each climate, so designing building system that can vary with ambient conditions seems necessary. Since the sunlight is one of the most important and effective climate factors in indoor conditions, in order to control of heat and light in the window, author got the basic idea from the shadow of a cup of tea. If the colored liquid is injected between double glazed windows, light passing through the window will reduce a lot. Variable Building Layers System (V.B.L.S) is an innovative design that has been patented by the author and can control heat transfer in buildings and improve thermal comfort.The system has been designed based on the basic idea after some trial and error and includes three main components: transparent layers, color tanks, pump and control valve. Its transparent layers can be made of tempered glass or Plexiglas that both of them are separated by a spacer. The way it works is that colored liquid is injected into layers through the pump. The system has the ability to change transparency in less than an hour and make one way vision glass, if necessary. Laboratory samples of this design were built during the 8 stages of the process which includes: -1 Controlling light passing through the window by colored liquid, -2 Controlling light passing through the window by various colors, -3 Controlling window visibility and transparency, -4 Creating various colors by mixing primary colors, -5 The ability to use the idea for walls: Using window idea in designing internal walls and Using window idea in designing external walls, -6 The ability to paint a wall with various colors, -7 The ability to move the location of thermal insulation, 8. The ability to control the system by a computer. In this paper, Variable Building Layers System is explained and discussed in detail as it is used for windows and walls. Three transparent layers that is injected colored liquid between them will create variable properties in windows and walls. The main objective was to achieve maximum variability in building walls and it was assumed that changing colors will decrease or increase the light passing through layers, so in order to prove this hypothesis, experiments were performed. Due to different absorption and passing light from various colors their shadow had a different temperature.
