1. 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 2-4. fkalmar@mfk.unideb.hu csiha@mfk.unideb.hu www.mfk.unideb.hu PLEA2006 The 23 nd Conference on Passive and Low Energy Architecture Geneva, Switzerland, 6-8 September 2006

2. 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

3. 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

4. Original structures Basic characteristics of walls and rooms Refurbished structures

5. Heat gains for a room with 1m 2 West oriented glazed area Result of the simulation 1. Original structuresRefurbished structures

6. Internal temperature in a room with West orientation of the 2m 2 glazed area Result of the simulation 2. Original structures Admitted temperature zone Refurbished structures Admitted temperature zone

7. Admitted glazed area in function of the orientation (ti ≤ 24°C) Result of the simulation 3. Original structuresRefurbished structures

8. Thank you for your attention.
