Local Dynamic Similarity Model of Cross-VentilationPart 2 - Application of Local Dynamic Similarity Model | 2004 | English
The proposed local dynamic similarity model of cross-ventilation predicted ventilation flow rates more accurately than the conventional orifice flow model assuming constant discharge coefficients when discharge coefficients actually decreased with
Low and High Pressure Experimental Analysis of Ventilators for Natural Ventilation in Buildings | 2003 | English
The wind and buoyancy pressure driving forces for natural ventilation of buildings are very low, typically less than 10 Pa.
Natural ventilation is a sustainable, energy-efficient and clean technology that is well accepted by occupants.
Natural Ventilation through Large Openings - Measurements at Model Scale and Envelope Flow Theory | 2004 | English
An overview is given of the current position regarding the use of wind tunnel modelling and envelope flow theory for determining natural ventilation through large openings.
CFD (Computational Fluid Dynamics) modelling of particle transport has been applied for the control of airborne particles in the operating zone above the surgery table in an operating room.
Performance of Balanced Ventilation with Heat Recovery in Residential Buildings in a Cold Climate | 2003 | English
This study simulated the performance of various mechanical supply and exhaust ventilation systems, incorporating heat recovery, in a typical Finnish residential apartment building.
Room Air Distribution and Indoor Air Quality of Hybrid Air Conditioning System based on Natural and Mechanical Ventilation in an Office | 2003 | English
The characteristics of a hybrid air-conditioning system, utilising natural and mechanical 'task' ventilation, are investigated in an office setting.
Creating a computer model that is able to simulate different ventilation scenarios within a structure is essential for improving the understanding of passive designs that are both sustainable and environmentally acceptable.
The attribution of pollutant concentrations on buildings from local traffic - Effects on ventilation requirements - A Wind Tunnel Modelling Study | 2003 | English
This paper describes an analysis using the BRE Pollution Dispersion Wind Tunnel to estimate pollution concentration patterns on buildings in urban arrays due to local line sources of pollution, typical of vehicular traffic emissions.
The Sound Attenuator : Secondary Source of Contamination in Air-Conditioning Systems? | 2003 | English
The problem of the hygienic state of air-conditioning installations in many countries is still treated with limited attention and, in general, this issue is disregarded both when systems are designed and when the maintenance of already operating s
The Usefulness of Climatic Maps of Built-Up Areas in Determining Drivers for the Energy and Environmental Efficiency of Buildings and External Areas | 2003 | English
Global Information Systems (GIS) are being used to provide data on a wide range of environmental issues, and in the area of climate studies they are being used to determine zones of towns and cities where there are good or poor external environmen
The aim of this work is to investigate turbulent air flows, through measurements inside railway coaches employed for the transport of sick persons.
Natural ventilation, which may provide occupants with good indoor air quality and a high level of thermal comfort, and reduce energy costs, has become an important sustainable strategy in building designs.
The observation of wind pressure acting on the wall and floor of a full-scale building model under cross ventilation was carried out.
