This is a study on dirt and changes over time of Polytetra fluorine ethylene (PTFE) membranes used for membrane structures. Using an electron microscope, the physical states of membrane material surfaces which were exposed for about 6 years to sunshine are shown. And there was a lapse of 6 years, twelve part of PTFE membranes were evaluated by rate of dirt. Main findings are as follow ; (1) Chromaticity of transmission color is more transformation thaji reflection color. (2) Membranes were washed clean once five or six years. So luminous characteristics improved. (3) After membranes were exposed to the weather, indoor thermal characteristics does not change. (4) Reflection rate of dirt is larger than transmission rate of dirt.
