A Comparative Study of the Thermal Performance of Building Materials
A Comparative Study of the Thermal Performance of Building Materials PLEA 2006 23rd Conference on Passive & Low Energy Architecture Geneva, Switzerland 6-8 September 2006 Soofia T. Elias-Ozkan , Francoise Summers, Nesen Surmeli Department of Architecture, Middle East Technical University, Ankara, Turkey and Simos Yannas Architectural Association Graduate School, London, UK A Comparative Study of the Thermal Performance of Building Materials The study was carried out at the Kerkenes Eco-center in Yozgat, Turkey, on structures made of four different materials: Mud-brick Straw-bales Prefabricated concrete panels Autoclaved aerated concrete Temperature and humidity data were collected in the first three, twice: Before heating After heating Simulations were carried out for all four, with ECOTECT. Solar Energy in TURKEY 4. 3. Turkey is situated between 36 ° and 42° N latitudes 2. 1. Solar radiation belts Region Solar radiation (cal/cm2 d) Southeast Anatolia 344.8 Mediterranean 328.3 East Anatolia 322.4 Central Anatolia 310.3 Aegean 308.0 Marmara 275.9 Black Sea 264.5 Average 309.6 Sunshine duration (h/d) 8.2 8.1 7.3 7.2 7.5 6.6 5.4 7.2 Location Maps for Kerkenes Weather Data of Yozgat Diurnal averages of outdoor air temperature and solar radiation, for Yozgat, plotted against thermal neutrality bands The Kerkenes Eco-Center in Yozgat Straw Bale House at the Kerkenes Eco-Center Mud Brick Unit at the Kerkenes Eco-Center Prefabricated Building, Kerkenes Eco-Center AAC Building at the Kerkenes Eco-Center Raw material for the Straw Bale House Building with Straw Bales Building with Straw Bales Building with Straw Bales Building with Straw Bales Building with Straw Bales Straw Bale House at the Kerkenes Eco-Center Building with Mud brick Building with Mud brick Mud Brick Unit at the Kerkenes Eco-Center Environmental performance of Straw Bale Environmental performance of Mud-brick Comparing thermal performance under Unheated Conditions Three-day temperature and humidity charts for straw bale and mud brick under un-heated conditions Comparing humidity levels under Unheated Conditions Three-day temperature and humidity charts for straw bale and prefabricated under un-heated conditions Comparing thermal performance under Heated Conditions Comparing humidity levels under Heated Conditions Comparing thermal performance through Computer Simulations Future Studies: Comfort level of straw bale furniture

the south where it terminated against outcropping bedrock in the
passage. Pavers are relatively small with sharp edges.
