| Summary |
Recently, membrane structures have been introduced to the merchant facilities as well as the sports ones on a large scale.
However， membrane materials are so thin that there remains some problems from the view point of architectural environment.
This time, we have surveyed some environmental data for the membrane structure which we installed in Obihiro, Hokkaido in order to establish comfort space in cold climate area. (minimum out door temperature is about -20℃.)
We have found the following results that the distributions of illumination and temperature in the membrane structure are influenced by the sunlight to a large extent.
