Before starting to design an HVAC installation for treatment, supply and exhaust of air to and from a building the needs should be listed, transformed to requirements and their consequences analysed.
Persson M P S
The paper presents a short description of the measurement program and the data collected for the “SynergieHaus”-project initiated by PreussenElektra and partners (now merged to E.ON).
Maas A
Computational Fluid Dynamics (CFD) has been used to predict the indoor environment airflow and overall ventilation effectiveness of natural or mechanical air distribution systems.
Maghrabi A
Measurements of ventilation rates and internal temperatures have been recorded in a naturallyventilated auditorium with high intermittent heat gains for a wide range of weather conditionsat a UK site.
Clancy E M
This paper presents a recent field measurement study undertaken in 1999 on 73 recent Frenchdwellings.
Guillot K, Litvak A, Kilberger M, Boze D
The target in this study was to decrease the energy use for transportation of air (fanenergy) with a factor of three.
de Gids W, Phaff H, Knoll B
In natural ventilation systems, fresh air is often provided through opening of windows, andthere is a wide range of possibilities with regard to selection of window type and position inthe facade.
Bjorn E, Jensen J, Larsen J, Nielsen P V, Heiselberg P
The move towards improving building air-tightness to save energy has increased theincidence of poor indoor air quality and associated problems, such as condensation onwindows, mould, rot and fungus on window frames.
Riffat S B, Gillott M C
Ventilation needs in dwellings must be determined on the basis of both requirements to theindoor air quality and necessary control of moisture conditions.
Bergsoe N C
The estimate of actual air change rates considering atmospheric turbulence isintroduced. The starting point is the spectral description of turbulence - Kaimalspectrum was used in order to consider the height above ground.
Marques da Silva F, Saraiva J G
This paper outlines work in progress to develop dissemination material to assist the appropriate application of solar and passive ventilation in urban buildings.

In France, the regulation on residential building ventilation is based, since 1969, on a generaland continuous air renewal ; the fresh air comes into habitable rooms by air inlets and thestale air is drawn out to exhaust vents in the service rooms
Noel O, Millet J-R, Villenave J G
In this study, computational fluid dynamics (CFD) and a variety of mixing models is used to evaluate the indoor air quality in a small single-family house.
Huang J, Chen Q
A Ventilated roof component was built and tested in the outdoor testing facilities (Test Cells) of CRES, Greece.
Dimoudi A, Androutsopoulos A, Lykoudis S
In this study, we investigated the indoor air quality (IAQ) in classrooms with exhaustventilation systems and in naturally ventilated classrooms. In the latter, we found peak CO2-concentrations of more than 4000 ppm.
Weinlader H, Beck A, Fricke J
This article describes a ventilation system, developed within the framework of aEuropean project supported by the JOULE III programme (NAVAIR project).
Noel O, Le D‚an P, Krikorian O, Haller R
A number of single tracer gas techniques (decay, step-up, homogeneous constant emission,inlet pulse and homogeneous pulse) suitable for measuring the local mean ages of air in multizonebuildings exist, each having their advantages and drawbacks.
Stymne H, Hansson P, Boman C A
A Tool Kit was developed to assess indoor air quality.
Richardson G, Eick S A, Harwood D J
Natural ventilation is one of the most fundamental techniques to reduce energy usage inbuildings.
Zhai Z, Hamilton S D, Huang J, Allocca C, Kobayashi N, Chen Q
The traditional way to dehumidify the outdoor air in an A/C-system is by cooling the air downbelow the dew point temperature. For this process a refrigeration system is necessary torealise these low temperatures.
