Design and improvement to improve the design and building wall building
.Before improvement heat transfer a total of outer wall building (OTTV) was about thirty nine point seven nine watts per square meter. Therefore, the design, reduce the area of glass walls
by adjust wall fiber cement thickness 10 mm.The middle lining with fiberglass insulation with low thermal conductivity, about 0.038 W2m.K thickness 3 finger
.And the glass walls did not improve as the wall. The installation of film cooling with heat protection features in the film with the value SC = 0.23 and the SHGC = 0.201 result after improvement of design value OTTV of buildings is reduced to 18.95 watts per square meter. In line with the simple research project scope that stated that the OTTV must not exceed 20 watts per square metre
