Contains 22 titles and abstracts.
Volume content
Conceptual procedure to achieve good air tightness in large buildings, using the example of the EU press centre of the council of ministers | 2009 | English
Experiences of the past years showed that it is possible to achieve a considerably better air flow rate in large buildings than it is targeted by the regulation of energy saving.
Building Expertise versus Freedom of Construction!? About the handling of residual leakages in compliance with Air Tightness Limit Values from the legal point of view | 2009 | English
The airtight version of a building envelope has been accepted as a structural engineering challenge in by construction workers in Germany.
Airtightness and energy use of an Swedish office building - measurements and calculations | 2009 | English
The airtightness of office buildings influences energy use and thermal comfort. A leaky office buildingis likely to have a high use of energy and thermal discomfort.
Requirements of Airtightness for Moisture Control in Attic based on Whole Building HAM Model | 2009 | English
Attic moisture control is one of the key issues addressed by the hygrothermal design of wood-frame houses. In general, exfiltration and natural ventilation are recognized as the main factors in determining the hygrothermal behaviour of an attic.
Air tightness of the building envelope contains important initial data for hygrothermal design and energy calculation.
When two adjacent residential buildings in Ludwigshafen were fully renovated in 2005/2006, energyefficiency was a focal point from the very beginning.
The developed method uses Radon as natural tracergas, which appears everywhere in the nature hence in all buildings as well.
Vapour convection becomes calculable - Unsteady model for consideration of convective moisture ingress at the simulation of lightweight constructions | 2009 | English
So far, the ideal-tight typical cross section is usually considered at the evaluation of constructions with the help of hygrothermal simulation.
Building Airtightness in Czech Technical Standards and Related Documents - Last Updates | 2009 | English
The basic statistics of airtightness test results collected since 2002 in the Czech Republic arepresented. The test results are compared with the limit values according to national standard CSN 730540-2.
An object reconstructed for residential purposes approved to be not sufficiently air tight. With methods that are generally known as inappropriate, it was tried to improve the air tightness subsequently to a reasonable level.
Field Survey on Air-tightness, Ventilation Rate and Indoor Air Quality of 77 Houses in Japan | 2009 | English
In order to determine the causes of SHS (Sick House Syndrome), a field survey on indoor air quality and health conditions of occupants has been conducted for 8 years in 77 detached wooden houses in Japan.
This paper investigates the practical feasibility of an exterior air barrier for the construction of a recently constructed light weight passive house in Ghent, Belgium.
Creating drying reserves! Consideration of convective moisture stresses for the evaluation of wooden constructions | 2009 | English
Already in the year 1983, the general basis paper for noting air tightness, which was elaborated by the Swedish construction council for the AIVC, pointed to the particular risk of moisture stresses in consequence of water vapor carriage due to ai
"Performance" project: Improvement of the ventilation and building air tightness performance in occupied dwellings in France | 2009 | English
As we increase energy requirements on ventilation, it is essential to assess the real performance of these systems on site, both for energy savings and IAQ aspects.Applied on two new buildings located in Paris and near Lyon (France), "Performance"
From the year 2007 the buildings must have energy efficiency calculations, which requirements arenow part of Building Code Book.
The combination of air tightness measurements and thermography introduces new application areas for both practices: the building thermography will be extended by a systematic leakage locating in the building envelope and during air tightness measu
Although there have been built about 20 sports halls with passive house standards by now, where the principles of residential houses and first experiences of built sports hall projects were used, but concerning the principles, there are still cons
There is increasing recognition of the importance of quantifying the airtightness of large commercialand residential buildings. Often these tests must be performed with multiple fans and technicians,usually within a narrow time window.
The role of air tightness and heat recovery in the ventilation system of energy-efficient office buildings in Norway | 2009 | English
With the background of different climates within Norway it was interesting to show the resulting differences in energy demand for the same typical office building.
