VIP 25: Trends in the Japanese building ventilation market and drivers for changes

Technology in building physics and mechanical engineering for building ventilation may not be totally new area and must have rather long history and much knowledge accumulation of their own.
Nowadays, the distance between the engineering field and society looks becoming shorter, since there are stronger needs from the society than before to reduce the environmental impact of the buildings and to enhance the indoor environmental quality with cost effectiveness, at the same time.

VIP 24: Trends in the Polish building ventilation market and drivers for changes

The Polish ventilation market is changing rapidly.
There are a number of key forces that drive the changes in the Polish ventilation market; the consumers, the rising energy costs, the incorporation of a great number of CEN standards into the set of Polish Standards and the implementation of the EPB Directive.

VIP 23: Trends in the Brazilian building ventilation market and drivers for changes

The paper presents an overview on building ventilation, indoor air quality and energy requirements in Brazil.
Regulations, standards and market practices are reviewed.

VIP 22: Trends in the US building ventilation market and drivers for changes

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.

VIP 21: Trends in the Norwegian building ventilation market and drivers for changes

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.

VIP 20: Trends and drivers in the Finnish ventilation and AC market

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.

VIP 19: Trends in the French building ventilation market and drivers for change

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.

VIP 18: Trends in the Belgian building ventilation market and drivers for change

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.

VIP 17: Trends in the building ventilation market in England and drivers for change

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.

VIP 16: Air quality in passenger aircraft

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.
