LoginTemperature 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
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Within the EU project NATVENT, which deals with the application of natural ventilation in office type buildings, one of the items to be studied was controlled air flow inlets.
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 certain conditions which are of interest when designing for natural ventilation ofcommercial buildings.
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.
This paper considers the role of passive stack chimneys in controlling indoor thermalconditions in the vernmlar houses on the volcanic island of Santorini .
As everybody knows, today the air quality of an indoor environment may have several effectson our health; the beginning of serious breathing pathologies and of some forms of cancer,are with no doubt due to the presence of polluting and extremely n
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.
Costs are one of the main decision factors for the selection of domestic ventilation systems.This often leads to a ventilation system that just meets the requirements of buildingregulations at the lowest initial costs.
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.
Many post-war residential buildings in the Netherlands have collective heating systems with poor energy efficiency. Also ventilation and DHW systems usually do not comply with current requirements.
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.
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.
A passive tracer gas technique - the homogenous emission technique was utilised formeasuring the air distribution in a part of an office building with displacement ventilation.Measurements were made during one winter period and one summer period.
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.
The work discussed here concerns the conditions of comfort obtained in a room cooled by a fan coil in relation to the form of air flow obtained. It is based both on practical experiment and on numerical simulation using CFD code.
An investigation of some Indoor Air Quality (IAQ) parameters in a significant office of the State in the area of Rome was undertaken.
IEA Annex 27 "Evaluation and Demonstration of Domestic Ventilation Systems" has been engaged in developing the evaluation tools for various aspects of their performance.
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.
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
