Stack ventilation and cooling for urban sites - research project funded under the UK "Partners in Technology Programme". | 1997 | English
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.
Evaluation of thermal comfort impact of direct fresh air supply in Winter. Part 2: comparison of different ways of air supply to exhaust only ventilation. | 1997 | English
IEA Annex 27 "Evaluation and Demonstration of Domestic Ventilation Systems" has been engaged in developing the evaluation tools for various aspects of their performance.
Evaporative cooling is an interesting alternative to conventional compressor refigerationsystems for air-conditioning.
Controlling ventilation and space depressurization in restaurants in hot and humid climates. | 1997 | English
Testing was performed in 9 restaurants to identify uncontrolled air flows and pressureimbalances, building and duct system airtightness, building air barrier location, pressuredifferentials, building air flow balance, and ventilation rates.
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.
A study of window location and furniture layout to maximise the cooling effect for an urban Taiwanese apartment by night ventilation. | 1997 | English
The year-round climate of Taiwan is warm and humid. Apart from the hottest months in summer, there are four months suitable for nocturnal ventilation to acquire indoor cooling.
Solar control devices placed in front of large building openings disturb air flow and theradiation transfer.
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.
In this paper the potential of night ventilation techniques is investigated. Extended real scalemeasurements have been performed, in three buildings, under free floating and airconditioned operation.
A model for the application of probabilistic methods is the estimation of heat loss caused by convection and heat conduction through the material is developed.
IAQ and natural controlled ventilation requirements - performance and standard aspects. | 1997 | English
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 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.
The concept of 'build tight - ventilate right' requires minimising air infiltration through theenvelope of a building and then providing adequate ventilation in a controlled manner tosatisfy the fresh air requirements of occupants.
Air distribution in an office building as measured with a passive tracer gas technique. | 1997 | English
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.
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.
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.
The U.S.
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.
