The importance of adventitious air leakage under normal operational conditions and its reduction in order to save energy is highlighted by the relvant building standards of many countries.
Applicability of air supply type airflow window system applied to double-pane window | 2012 | English
It still remains heat loss and high risk of moisture condensation occurrence at glass of window because they have relatively poor insulating qualities and usually contribute the greatest heat loss by heat conduction in residential buildings.
An efficient thermal insulation of glazing or window frame is important because poor insulating performance usually cause the largest heat loss on any buildings.
Accuracy in estimation of airflow through windows is the key parameter for modelling and designing of naturally ventilated buildings. The flow through windows is usually described by the orifice flow plate equation.
Effect of measurement location of air air-tightness performance on apartment units in Korea | 2012 | English
The purpose of this study is to evaluate the effects of measuring position of air-tightness performance in Flat-type and Tower-type apartments.
Potentials and limitations of ventilative cooling strategies in the moderate central Europe climate region | 2012 | English
The paper in hand investigates the potentials and limitations of ventilative cooling strategies in the moderate Central Europe climate region of Vienna, Austria, offering a a basic load break down of the thermodynamic night ventilation sub-process
A multi-criterion method for examining the health and energy impacts of air change rates in dwellings | 2012 | English
The global requirement to dramatically reduce greenhouse gas emissions places an increased emphasis on reducing energy demand associated with dwellings.
The work evaluates the applicability of façade-integrated ventilation systems in a Nordic climate.
Blower door tests of a group of identical flats in a new student accommodation in the arctic | 2012 | English
A new student accommodation for engineering students “Apisseq” was built in the town of Sisimiut, Greenland in 2010. Its purpose is not only to provide accommodation for students.
Human preference and acceptance of increased air velocity to offset warm sensation at increased room temperatures | 2012 | English
Previous studies have demonstrated that in summertime increased air velocities can compensate for higher room temperatures to achieve comfortable conditions.
Improvement of summer comfort by passive cooling with increased ventilation and night cooling | 2012 | English
The present study describes the potential improvement of summer comfort and reduction of energy consumption that can be achieved by adopting passive cooling solutions, such as daytime comfort ventilation with increased air velocities and night coo
Air turbulence intensity influence on the thermal comfort evaluation for different ventilation strategies | 2012 | English
Thermal comfort is a subjective term, closely related to the sensation of warm or cold for the occupants, defining the state of mind of humans that expresses satisfaction with the surrounding environment.
RANS and LES models comparison for a cross-shaped jet flow with application in personalized ventilation | 2012 | English
The need for thermal comfort and clean air for occupants in buildings or vehicles is vital since we spend more than 90% of our time inside these enclosed environments.
A numerical study on the role of leakage distribution and internal leakages under unsteady wind conditions | 2012 | English
The existence of air leakages in a building has been very clearly stated as an important reason for energy loss. The decrease in the efficiency of the mechanical ventilation has also been clarified.
Update of the spanish regulation regarding ventilation and infiltration: analysis, comparisons and repercussions | 2012 | English
The Spanish Technical Building Code is one of the three royal decrees that were approved in Spain as a consequence of the transposition of the European Directive on the energy performance of buildings (2002/91/EU) .
The new Nicosia Town-hall is a very particular building. On the site where it is built, important antiquities were discovered during the first day of construction and the whole design was completely modified to fit to the new situation.
Low energy buildings, being highly insulated, are subject to important overheating risks. Thermal simulation as well as experimental studies have shown the large potential of ventilative cooling.
Natural ventilation and passive cooling simulation is not any more a privilege of experts | 2012 | English
Natural ventilation and dynamic temperature simulation of buildings was until now a priviledge of highly skilled building physicists. Combined simulation of both is even rarer.
