Interrelation between glazed Surfaces, Building Structure and Thermal Comfort Ferenc Kalmár and András Csiha Department of Building Services, University of Debrecen Debrecen, Hungary 4028 Debrecen, Ótemető utca PLEA2006 The 23 nd Conference on Passive and Low Energy Architecture Geneva, Switzerland, 6-8 September 2006

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 ~2m 2 (different orientations). Admitted temperature zone

Original structures Basic characteristics of walls and rooms Refurbished structures
