The 35th AIVC Conference " Ventilation and airtightness in transforming the building stock to high performance", was held in Poznań, Poland, 24-25 September 2014. Contains 86 papers.
Volume content
Airtightness becomes a more and more important parameter in the rationalization of the energy consumption. The quality of the works during the…
Higher insulation and air tightness levels of buildings, increase the risk on overheating. Ventilative cooling as passive technique can limit overheating…
The mixing of a tracer gas with zonal air was compared between two zones in an unoccupied test building in both the horizontal and vertical direction. A…
Passive cooling by night ventilation is one of the most promising approaches to reduce cooling energy demand of office buildings in moderate climates.…
Traffic emissions have a significant impact on urban air quality, which particularly concerns street canyons, i.e. spaces with limited air exchange. Traffic…
Many buildings in Sweden are in need of renovation in order to meet the current standards of energy use in buildings. Particularly challenging are old…
A voluntary certification for very low energy buildings has been implemented in 2013 in France, which requires among other the ventilation systems to be…
When one intends to evaluate buildings energy efficiency their airtightness is a fundamental parameter. Airtightness is linked to undesirable and…
In recent years there has been much emphasis on improving the energy performance of Irish buildings. Much of this impetus stems from our requirements to…
Variable air volume (VAV) ventilation systems reduce fan power consumption compared to constant air volume (CAV) systems because they supply air according…
The framework of the research presented in the paper is a project oriented to promote the use of concrete solutions in buildings based on maximizing the…
The airtightness test of the building is one of a few building envelope measurements used in practice, which is quantitative, not just qualitative as e.g.…
As the benefit of natural ventilation in reducing operational cost is well recognised, the concept of natural ventilation is becoming more received by…
The energy efficiency and energy consumption of mechanical ventilation systems depend mainly on the heat and cool recovery efficiency and the operational…
The aim of the project was to evaluate how the air tightness of buildings changes over time and how the sealing materials are affected during the expected…
Nearly all retail locations use ventilation and cooling systems to ensure adequate air exchange for health reasons and indoor comfort temperatures. These…
Energy performance of mechanical ventilation systems in modern low energy and passive buildings is a crucial factor influencing overall energy performance…
Air tightness is essential to building energy performance, which has been acknowledged for a long time. It plays a significant role in improving building…
A new school building block in Passivehouse standard near Kortrijk (Belgium) is in use since spring 2013. The urban development regulations required that…
The future is well-isolated buildings with low heating demand. The first office building in Norway satisfying the passive house standard, the GK…
