LoginThe paper reviewed the supply opening models of describing inlet boundary conditions for indoor airflow simulation firstly. Then examples of isothermal free air jets from a grille are presented to validate full representation of supply openings.

Evaluation and development of innovative and energe efficient ventilation strategies. | 2001 | English
A potential conflict may exist between energy saving and good indoor climate.
In this study a parametric analysis was carried out of the interaction between louvres and various perforated mesh screens. This type of arrangement is common in through-the-wall ventilators used for natural ventilation in buildings.
This paper briefly exams the role of the building envelope in determining the internal environmental conditions in buildings and the scope for holistic design of building services and building envelope.
The NEN 5128 "Energy performance of dwellings and residential buildings- Determination method" [1] describes a procedure to calculate the energy performance coefficient EPC. The requirements are given in the Dutch Building Decree [2].
Thermal bridges are the typical locations for moisture and mould problems in buildings. Low surface temperatures in combination with a high humidity level in buildings can lead to severe problems and complaints by the occupants.
European project pr EN13465 from CEN TC 156/WG2/AH4 gives a monozone model for airflow calculations in dwellings.
Testing a method for checking the performance of ventilation systems in commercial buildings in France. | 2001 | English
Ventilation performances in existing buildings are not well known, in France. They are not often checked. This paper shows how a method for checking the performance of ventilation could be applied in France.
Ventilation plays an important role in the RT 2000 regulation. The ventilation system is of course taken into account, but also the building envelope airtigthness on which this paper focuses.
Building-integrated photovoltaic (PV) systems are increasingly common in developed countries and have the potential to contribute significantly to electricity generation as a benign alternative to fossil fuel generation.
The "Intelligent Facade" is seen as a central element in the evolution of building form and building fabric to provice environmental control and comfort.
Following calculations of potential energy savings, several types of earth-air heat exchangers have been coupled to buildings in novel concepts for passive heating and cooling of ventilation air.
Ventilation plays an important role in the RT 2000 regulation.
Most dwellings in the United States are ventilated primarily through leaks in the building shell (i.e., infiltration) rather than by whole-house mechanical ventilation systems.
A major concern of those wishing to limit the energy use in buildings is the growing trend towards installing air-conditioning in new and refurbished buildings.
The aim is to develop a new method for comfort in settings with high thermal load in buildings that do not require continuous cooling but cooling only during shorter periods. Example of such buildings is schools.
This paper summarizes part of the work held at ENTPE within the framework of the IEA Annex 35 project.
COOLHOUSE - cooling buildings in southern Europe using innovative ventilation strategies. | 2001 | English
The Coolhouse project is exploring the viability of alternatives to air-conditioning in southern European countries using innovative passive and low energy cooling and ventilating techniques, with an emphasis on ground cooling.
For over 20 years, the AIVC has been a key player in developments in technical knowledge on ventilation and related issues, and has always been very active in the dissemination of information.
Dynamic insulation is a very good example of a ventilation system integrated with the building envelope. The paper describes two recent studies carried out at Nottingham on dynamic insulation.
