The residential ventilation market is changing rapidly in the United States.
Dwellings are going from having no designed ventilation systems to have to meet specific requirements.
The drivers are local codes and large scale programs being implemented by states and utilities and the federal government.
Residential ventilation products are adapting to meet the evolving needs of the market.
New products are coming out frequently and presumably more are in development.
By contrast the market for nonresidential ventilation is reasonably mature.

IAQ and ventilation is given rather high attention in the Norwegian building industry.
The new energy demands, basically an implementation of the EPBD, are a major driver for change.
In practice it makes modern energy efficient ventilation compulsory in all types of buildings, which was not the case up to now.

Performance based indoor climate and ventilation regulations, having mainly been based on the requirements for the end result with fewer requirements for the system description, supported by a voluntary advanced indoor climate classification and labelling system, have arguably led to the best indoor climate standard in the world in both residential and commercial buildings.
In this respect, the Finnish story is ultimately a success story.
On the energy performance side, the primitive regulation based only on the requirements of U-values has caused some drawbacks.

Building ventilation has been covered by French regulations for many years.
Attention is paid to the general design of ventilation systems, air flow rates, energy consumption due to air renewal and fans, air tightness of building envelope and ventilation ducts, noise, fire risks.
However there exists a large need for improved information and training of all the actors in the construction process, in order to increase buildings quality in the framework of this changing regulations landscape.
Attention for and implementation of ventilation systems is a relatively new phenomena in Belgium (where the three Regions are in charge of regulations related to ventilation).
It is clear that the energy performance regulations are a major driver for change.
A specific feature of the Belgian legislation is a rather strict control scheme.
In order to stimulate the market uptake of innovative systems, a legal and technical framework is in development.

This Information Paper has been written in the framework of the Building AdVent project and reviews recent changes in the Building Regulations in England and Wales introduced in 2006 to facilitate the implementation of the EPBD.
The paper covers changes in building ventilation and energy performance including envelope air tightness and duct air leakage considerations.

This VIP focuses on best practice, as well as challenges, for the conditioning of the indoor environment in passenger aircraft cabins, and their implications from a ventilation stand-point.
This article is based largely on findings from EU’s FP5 project “CabinAir”.
In early commercial jet aircraft, passenger cabins were ventilated with 100 % outside air. In more recent jet aircraft, approximately 50 % of the ventilation air is outside air and the remaining 50 % is filtered recirculated cabin air.

The 2nd European BlowerDoor Symposium “Airtight building envelope, thermography and dwelling-ventilation” took place on the16th and 17th March 2007 in Kassel, Germany. 150 participants from 13 European nations and 20 companies took part in the symposium and the trade fair. The contributions came from Belgium, Germany, Finland, Greece, Austria, Switzerland and the Czech Republic.

The European Directive 2002/91/EC on the energy performance of buildings (the EPBD) imposes to the EU member states several different measures to achieve a more rational use of energy resources and to reduce the environmental impact of the energy use for buildings (see also VIP 9).

Ceiling fans are one of the more credible techniques to decrease the energy consumption for air conditioning and improve comfort. Historically, ceiling fans have first emerged in hot humid climates and have become more and more popular in certain parts of the world from the early decades of the last century.
