Air distribution in an office building as measured with a passive tracer gas technique. | 1997 | English
Natural cross ventilation for refrigerative cooling reduction in a well insulated apartment. | 1997 | English
In this paper the energy impact of natural cross ventilation is examined conducting a set of crossventilation experiments in a well insulated apartment of a 5-storey building.
Prediction of the potential of self regulating natural ventilation devices: methodology and practical results. | 1997 | English
The performances of self regulating natural ventilation devices (devices of which the openingsection varies as function of the pressure difference across the device) strongly depend on thetype of building and its leakage characteristics.
In France, mechanical cooling is increasingly used in office buildings.
This study aimed to research the airtightness of the building envelope in apartments before and after renovation. Measurements were carried out in three apartment buildings. One to four apartments were examined in each building.
Four types of heat-pipe heat recovery systems were tested for application in passive stackventilation. The effects of fin shape, pipe arrangement and air velocity on the heat recoveryeffectiveness were investigated.
Due to the lack of proper sensors for odours, the odour concept, involving the unitsolf and decipol, is of very little practical use with respect to automatic control of VAVsystems.

The significance of traffic related pollution levels and its dilution associated with altitude. | 1997 | English
This paper identifies the significance of pollution at five sites amongst the worst on the British mainland hence indicative of other polluted areas within Europe. Three sites are located in London and one each in Birmingham and Cardiff.
There are a number of methods available concerning with distribution of air in buildings. Within control research, one can find new control algorithms which have not yet been used in practice.
One of the first sorption-supported air-conditioning systems ("Desiccative Evaporative Cooling Systems") in an industrial building in Germany was installed in a printing office in Waiblingen, a town in southern Germany.
The IEA project Annex 27, Evaluation and Demonstration of Domestic Ventilation Systems,have come to the stage that simplified tools can be presented in a total scheme.
This paper will present a general approach that may be used to solve natural ventilation designproblems typically addressed at the preliminary design stage - How wide should windows beopened in a given building for wind-driven cross ventilation on
A difficulty when designing natural ventilation in office buildings is the lack of simple designtools.In order to be able to predict natural ventilation air flow rates and indoor air temperatures atthe design stage, a computer model has been devel
Temperature and cooling demand in a room summertime are influenced by numerous factors,like internal gains, ventilation, solar gain, behaviour of occupants, thermal inertia of the roomand outdoor conditions (climate).The thermal environment and co
Study of the ventilation on an ancient building located in the centre of Rome and now used as a university office. | 1997 | English
An investigation of some Indoor Air Quality (IAQ) parameters in a significant office of the State in the area of Rome was undertaken.
This paper discusses summer cooling of buildings by means of natural ventilation. Computational fluid dynamics is used to predict the ventilation rate in a room with a Trombe wall.
Natural passive stack ventilation (PSV) consumes no power and so produces no harmfulemissions, has no running cost, no noise of operation, requires little maintenance and becauseit involves no moving parts, operation is reliable.
In the present paper a model for steady-state thermal analysis of ventilated and unventilated light rook is proposed.
In the framework of the Flemish Impulse Programme on Energy Technology (VLIET), the project called SENVIVV is running from January 1995 till September 1997.
