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.
Deterministic and non deterministic methodologies for the prediction of the air velocity in single sided natural ventilation configurations. | 1997 | English
An extensive experimental program on single sided natural ventilation was carried out within the frame of PASCOOL EC research project.
Introduction of air infiltration and ventilation in a simple modelling for energy consumption estimation in air conditioned buildings. | 1997 | English
This study reports on the introduction of air infiltration and mechanical ventilationin a model for energy consumption estimation. The model applies to air conditionned nonresidential building and is developped to need few inputs.
Continuously rising energy costs, the demand for reduction of CO2-emission and theprohibition of CFC-containing refrigerants create a base for new concepts of air-conditioning(A/C) systems.
There are certain conditions which are of interest when designing for natural ventilation ofcommercial buildings.
A method for the economical optimisation of the design temperatures and the connecting flows of a cooling system. | 1997 | English
The planning parameters of a cooling system for ventilation, for example the vaporization andcondensing temperatures, heat capacity flow rates, design temperatures and designtemperature differences have a strong influence on the investment and ope
IEA Annex 27: comparison of performances of different ventilation systems in similar dwellings. | 1997 | English
The main goal of IEA Annex 27 "Evaluation of ventilation systems" is to develop tools toevaluate ventilation systems in an objective way in terms of indoor air quality, energy,comfort, noise, life cycle costs, reliability and other building relate
