Windows of the buildings will be installed in a variety of sizes and shapes, but 2m × 2m sized windows(specimen) are evaluating U value by the KS F 2278, so there is a difference between windows that are applied to the actual building and specimen. In this paper, it is evaluated on U value by the effects of changes in size of windows, correlation was derived. The following conclusions were derived. 1) Depending on the type of spacer average U value difference is approximately 0.06 W/㎡·K. 2) 0.005 W/m·K increase in linear U value, U value is increased approximately 0.0094 W/㎡·K. 3) In the same conditions of the frame, as excellent U value of glazing, U value of windows bigger changes according to the window size changes. Later, the U value change analysis according to the size will be performed for various types of windows in order to provide a reasonable calculation criteria, so additional studies should be performed. |
