This study analyzes the effect of airtightness on the energy efficiency of single and adjacent containerized buildings, before and after refurbishment. It further gives an overview of air leakage problems found in the sample of prefabricated buildings manufactured and located in Turkey. The air leakage of standard container-like building depends on a number of factors like the age of the building, manufacturing quality and quality of assembly implementation. The airtightness of four typical containerized buildings has been measured. The fan pressurization method has been applied and carried out with the Minneapolis Blower Door test and complemented by Infrared Thermography Camera screening to document all leakages within the building envelope. All building energy simulations have been performed with WUFI Plus to investigate the outcome of the respective air leakage of the building obtained from site. Following that, retrofit measures have been applied on one of the sample buildings. Test and simulation procedures have been repeated after retrofit to compare results. The post-retrofit simulation results of the four buildings show that poor airtightness has a negative impact on the energy performance of the building. This information is crucial for the future development of improvement measures in manufacturing prefabricated buildings.

Assessing the airtightness performance of container houses in relation to its effect on energy efficiency
Tanyer, Ali Murat; Tavukçuoğlu, Ayşe (2018-04-15)
This study examines the airtightness performance of four types of commonly-used container houses (CHs) and its impact on their energy efficiency. One of the CHs was treated by sealing all junctions inside the container envelope. The airtightness levels of unsealed and sealed CHs were measured by using the fan pressurization method. The interior surfaces of building envelope were scanned by thermal imaging in order to locate the areas suffering from air leakages and thermal failures. The annual energy consum...
Modelling of strengthened hollow brick infills
BARAN, MEHMET; Ozcelik, Ramazan; Sevil, Tugce; Canbay, Erdem (2013-02-01)
Strengthening the existing hollow brick infill walls by bonding high-strength precast concrete panels or applying steel fibre reinforced mortar was found to be an occupant-friendly seismic retrofitting technique for the buildings in use with deficient reinforced concrete structural systems. Both techniques convert the existing non-structural hollow brick infill walls into load-carrying structural members. To verify the effectiveness of the techniques, 20 reinforced concrete frames with hollow brick infill w...

The Impact of surface texture and wind on convective heat transfer from building façades
Öztürel, Necil; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2013)
In this study, the impact of the surface texture of finishing materials and wind conditions on heat loss from the building’s facade are investigated. Three sets of samples (Set A, B and C) are tested and observed under varying wind speeds and varying wind angles in a wind tunnel. Both Sets A and B are composed of seven samples each, all having different surface textures. Set A samples were prepared from gypsum plaster and Set B samples from cement plaster mix. Set C consists of five different samples of con...
The development of a building energy performance evaluation program (EnAd) for architectural design process
Çakıcı, Fatma Zehra; Sorguç, Arzu; Department of Building Science in Architecture (2013)
Energy performance in buildings has become one of the most broadly debated subjects in contemporary architecture; and current legislation has emphasized its importance by requiring buildings to possess an energy performance certificate. Due to the technological advances in computational tools, it is possible to analyze the energy performance of buildings before construction starts; however most energy performance evaluation tools, requiring complex solid models and high technical knowledge in the field, can...
