The common EPIC – AIVC Conference was organized in Lyon France between 22 to 24 of November 2006. A very high number of excellent papers were presented and the conference was regarded as being of high scientific quality. 

More than 80 of the papers presented at the Conference dealt with ventilation studies and most of these reported very interesting and innovative results. Among the best papers, we have selected 10 which we believe merit publication in the International Journal of Ventilation. 

A conference report from the 27th AIVC and 4th Epic Conference  "Technologies & sustainable policies for a radical decrease of the energy consumption in buildings", held in Lyon, France, 20-22 November 2006.

A conference report from the 28th AIVC and 2nd Palenc Conference  " Building Low Energy Cooling and Ventilation Technologies in the 21st Century" held in Crete, Greece, 27-29 September 2007. This overview set is focused, mainly on ventilation aspects.

This paper gives the status on the regulation on ventilation in the different regions of Belgium for residential and non residential buildings. The effect of ventilation, building airtightness and duct airtightness on the energy performance regulation for buildings and its calculation method are specified. The various ways in which this regulation shows to act as a driver for market change, are identified. Due to the increased interest for energy efficiency, the ventilation industry is currently developing and promoting particular systems.

In 2003 the new extension of the German Museum of Technology (Deutsches Technikmuseum, Berlin), which comprises around 12,000 m?? of exhibition space was completed as a low-energy building. Planning and building this construction took almost 20 years (from 1987 to 2003). Validation measurements have been conducted since 2004. The building has been monitored by the Fraunhofer Institute for Building Physics IBP and IBUS (Institut fuer Bau und Umwelt, Berlin) during construction, in the commissioning phase, and during the period of validation measurements.

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. This operational leakage is often inferred via the measurement of air permeability, a physical property of a building that indicates the resistance of its fabric to airflow. A building’s permeability is the measure of airflow rate through its envelope at a constant pressure differential of 50 Pascals.

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. Although many attractive window systems are proposed to reduce heat loss such as double and triple glazing, low emissivity film coated glazing, argon gas injected glazing, vacuum insulated glazing, double-pane and triple-pane window etc., it has also demerits such as high initial cost and indoor air quality problem.

An efficient thermal insulation of glazing or window frame is important because poor insulating performance usually cause the largest heat loss on any buildings. As one of the methods decreasing heat loss of buildings, we proposed a dynamic insulation system applied to window frame, and its energy saving performance and applicability for buliding had been confirmed using numerical simulation in previous study [1].
