LoginDue 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.

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 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.
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
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
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.
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.
In the framework of the Flemish Impulse Programme on Energy Technology (VLIET), the project called SENVIVV is running from January 1995 till September 1997.
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.
This research is part of project NATVENT (TM), a concerted action of nine institutions ofseven European countries under the Joule-3 program.
NiteCool was developed under the Energy Related Environmental Issues in Buildings(EnREI) DOE Programme and is designed especially for the assessment of a range of nightcooling ventilation strategies.
The aim of the study was to investigate the operation of different types of ventilation in placesconstructed underground and ground level; the effect of ventilation on indoor radon levels wasalso examined.
Although several investigations on how to design airtight buildings have been performedand the results furthermore have been published, many designers and contractors are stillunaware of this knowledge.
Natural ventilation and the role of passive stack chimneys in traditional excavated and surface dwellings in Santorini. | 1997 | English
This paper considers the role of passive stack chimneys in controlling indoor thermalconditions in the vernmlar houses on the volcanic island of Santorini .
This study aims at evaluating the energetical benefits of increased ventilation airflow rate tocool buildings.
System safety analyses of the performance of mechanical ventilation systems - the quantitative approach. | 1997 | English
A method for estimating the reliability of mechanical ventilation systems in dwellings hasbeen developed. The analysis is based on component level reliability models interconnectedby so called fault-tree schemes.
