“…In order to define relevant control variables, a review of previous studies that have established predictive airtightness models in residential buildings [26] has been used. It is deduced that one of the variables with greater relevance is the year of construction [27][28][29][30]. Also, characteristics of the building such as typology [31], type of construction [30], type of window/glazing [15] and window frame [6,32], foundation [28], construction system [33], materials [15,24,32,34], floor area [28], total height [28], number of storeys [33], ventilation system [35,36], type of insulation [30] and sealing devices [34], and management type [31] should be considered.…”

Air leakage and its impact on the energy performance of dwellings has been broadly studied in countries with cold climates in Europe, US, and Canada. However, there is a lack of knowledge in this field in Mediterranean countries. Current Spanish building regulations establish ventilation rates based on ideal airtight envelopes, causing problems of over-ventilation and substantial energy losses. The aim of this paper is to develop a methodology that allows the characterization of the envelope of the housing stock in Spain in order to adjust ventilation rates taking into consideration air leakage. A methodology that is easily applicable to other countries that consider studying the airtightness of the envelope and its energetic behaviour improvement is proposed. A statistical sampling method has been established to determine the dwellings to be tested, considering relevant variables concerning airtightness: climate zone, year of construction, and typology. The air leakage rate is determined using a standardized building pressurization technique according to European Standard EN 13829. A representative case study has been presented as an example of the implementation of the designed methodology and results are compared to preliminary values obtained from the database.

“…The study showed that the hygrothermal conditions in hammams vary considerably over time and space and that fairly stable thermal conditions were achieved. In [30], the authors conducted a combination of field measurements and simulations in order to determine the renovation requirements. The analysis showed that the improvement of building service systems and the energy source holds the largest energy saving potential.…”

Night ventilation, is one of the most effective passive cooling techniques that may contribute to the improvement of the occupants thermal comfort conditions. Despite the justified effectiveness of night ventilation, few studies quantified its influence on the thermal comfort of vernacular buildings, especially under warm dominant climates. The aim of this study is the investigation of the impact of night ventilation on the thermal comfort of vernacular buildings under summer dominant environmental conditions. The subjects under investigation was one traditional buildings in the city of Nicosia in Cyprus. In terms of this study numerical analysis regarding the thermal comfort of the investigated buildings was performed by employing Energy Plus and the flow solver of Design Builder. The indoor operative temperature distribution, the indoor air velocity and a thermal comfort related index were identified in selected thermal zones of the examined building using night ventilation. The results of this study quantified the potential temperature decrease that can result on vernacular buildings due to the use of night ventilation and revealed some restrictions with regard to the allowed percentage of the opening sizes towards achieving optimal thermal conditions in space. This study aspires to provide useful insight regarding the importance of humans' behavior in terms of enabling night ventilation to vernacular buildings, as well as to con-tribute to the ongoing scientific discussion on this subject.

Abstract.This article containsreasoningof the heat transfer performance uniformity factor determinationfor attic floorsof historic residential buildings while energy effective modifying buildings. The numeral value of this heat transfer performance uniformity factor for the wooden attic floor structure was founddurung investigation. It was estimated that there was no moisture condensation in the wooden attic floor structure.
