Three type of the analyzed building structures
Traditional construction 1:
SD (sun-dried) brick
Traditional construction 2:
B30 brick (with vertical cavities)
Light (modern) construction:
wood frame structure
Measured data in the analyzed original building structures
Basic data of the analyzed and measured rooms: 4.00 x 5.00 x 2.80 m,two external walls,1 window of ~2m2 (different orientations).
