From January 1st 2013 on, the French energy performance regulation will demand that the airtightness level is justified and that airtightness of a building should be below 0,6m3/h/m² at 4Pa for single family housing and 1m3/h/m² for multi-family d

The efficiency of air-to-air heat recovery ventilation units is of great importance for EP calculations (energy performance of buildings) throughout Europe.
Samuel Caillou, Paul Van den Bossche
DIN 4108-7 requires a limit of q50 ≤ 3.0 m³/m²h for the air permeability of large buildings. Even stricter limits with respect to q50 can be found at DGNB [German Sustainable Building Council] and in the Swiss MINERGIE Standard.
Paul Simons and Stefanie Rolfsmeier
The aim of this paper is to investigate the influence of the selective ventilation in the thermal performance of modern naturally-ventilated houses built in the 1950’s and 1960’s in Goiânia, located in middle-west of Brazil.
Leônidas Albano da Silva Júnior, Marta Adriana Bustos Romero, Alberto Hernandez Neto
Reliable airtightness data is needed to calculate the estimate of air infiltration and the thermal loads for building energy efficiency and indoor comfort.
Yun Jeong Choe, Hyun Kook Shin, and Jan Hun Jo
Natural ventilation is increasingly considered a promising solution to improve thermal comfort in buildings, including schools.
Laura Lion, Annamaria Belleri, Roberto Lollini, Dino Zardi, Lorenzo Giovannini
Air quality in offices depends on the ventilation system ability to remove contaminants from the occupied zone.
Michele De Carli, Roberta Tomasi, Roberto Zecchin, Giacomo Villi
Despite a lot of Integrated Design Process guidelines and procedures have been developed in the last few years, more specific energy design procedures are needed to push the implementation of passive design techniques.
Annamaria Belleri, Roberto Lollini
This article deals with summer comfort and room air distribution in low-energy housings. In such buildings, the efficient thermal insulation and air tightness make it crucial to efficiently dispose of the heat released by the internal gains.
Axel Cablé, Ghislain Michaux, and Christian Inard
Diffuse ceiling ventilation is a novel air distribution device that combines the suspended acoustic ceiling with ventilation supply.
Christian Anker Hviid, Søren Terkildsen
The stock housing of England (UK) constitutes the oldest housing stocks in the world.

by space and water heating. The high costs of energy are a national matter not only for their economic and environmental implications, but also because they contribute largely to a social problem, known as fuel poverty.
Raniera Barbisan and Hasim Altan
French standard for airtightness measurements is NF EN 13829. It is completed by French application guide GA P50-784, to set calibration rules more precisely, among other issues. This guide was published in 2010.
Florent Boithias, Sarah Juricic, Sylvain Berthault
In France, starting January 1st, 2013, the energy performance regulation will impose an airtightness treatment for every new residential building.
Adeline Bailly, Valérie Leprince, Gaëlle Guyot, François Rémi Carrié, Mohamed El Mankibi
The energy consumption needed for establishing a good indoor climate in shopping centres is often very high due to high internal heat loads from lighting and equipment and from a high people density at certain time intervals.
Gitte T. Tranholm, Jannick Karsten Roth and Lennart Østergaard
Hybrid ventilation (HV), as a combination of automated natural ventilation (NV) and balanced mechanical ventilation (MV), provides opportunities to use the advantages of both ventilation systems during the seasons in order to reduce energy demand
Simone Steiger, Jannick Karsten Roth and Lennart Østergaard
The UK Government strategy for all new homes to be built to zero carbon standards by 2016 is based upon a “fabric first” approach to design.
Tim Taylor, John Counsell, Andrew Geens, Steve Gill and Gerraint Oakley
BR10 requires that all new residential constructions should be built as low energy housing. In order to meet these requirements residential buildings must be equipped with far more complex technology, than conventional housing.
Ditte Marie Jørgensen, Anders Høj Christensen
The objective of this study was to develop a method for hourly calculation of the operating temperature in order to evaluate summer comfort in dwellings to help improve building design.
Lone H. Mortensen and Søren Aggerholm
Sizing rules in residential ventilation standards lack uniformity in both methodology and resulting design flow rates.
Jelle Laverge, Xavier Pattyn and Arnold Janssens
