Numerical assessment of thermal comfort and air quality in an office with displacement ventilation. | 1994 | English
In order to reduce the heat loss from buildings it is common to increase the thickness of insulation in the building envelope.The consequence of this action is more expensive buildings.
User experiences of the workings of a ventilation system have often been pretty disheartening. Draughty, too hot, noisy, too stuffy are some of the verdicts which in many cases have been confirmed by objective measurements.
The Annex 27 (A27), Evaluation and Demonstration of Domestic Ventilation Systems, is given a genaral introduction.
The mechanical ventilation of suspended timber floors for radon remediation - a simple analysis. | 1994 | English
Mechanical ventilation of the underfloor space is one of the most effective ways of reducing radon levels in buildings with suspended timber floors.
BRE have experimental data for the flows found in Passive Stack Ventilation (PSV) ducts from a test house in Garston.
The acquisition of temperatures and velocities is a permanent recurrent task for the investigation of air flow in ventilated rooms. On the one hand it is important to measure the temperature and velocity field with a high spatial resolution.
A design guide for displacement ventilation (thermally induced ventilation ) has been prepared. It is based on quasi stationary experiments carried out in the Sulzer Infra laboratory in Winterthur.
The aim of the study was to identify methods for the renovation of ventilation systems in domestic buildings which are 3 - 8 storeys high. Three typical buildings were selected and the problems in ventilation were examined.
Application of a multi-zone airflow and contaminant dispersal model to indoor air quality control in residential buildings. | 1994 | English
A new multizone airflow and contaminant dispersal model CONTAM93 is described, along with a demonstration of its application in a study of ventilation and contaminant control in single-family residential buildings.
The role of ventilation in controlling the dispersion of radon gas from a cellar in a domestic house. | 1994 | English
In certain parts of the United Kingdom where radon gas seeps from the ground into the basement of domestic housing, normal methods of removing this gas by using under floor extract ventilation is not appropriate.
The UK factory stock is predominantly naturally ventilated.
The airflow between a warm room and cool exterior can be significantly affected by an external headwind. Pollutant concentrations within the space depend on the relative sizes of the wind and the undisturbed stack driven flow.
The relative energy use of PSV and extract fans has been a matter of considerable controversy, particularly in the UK.
Determination of local mean ages of air by the homogeneous injection tracer gas technique. | 1994 | English
The paper describes the application of a new tracer gas technique for studying ventilation.
In recent years plants have increasingly become an integral part of building interior design. Greened office space and large enclosures can provide a better human environment not only because of psychological reasons.
The paper is presenting experience from a several year long time of operation in a group of apartment buildings in the Stockholm area, Sweden, having an extremely low energy usage, less that 110kWh/(m2.year), electricity supply to the building ser
The system of decentralized apartment ventilation has been successfully used for several years in multiple-storey apartment construction in the Federal Republic of Germany.
Four classrooms of two secondary schools located around Lyon in France have been monitored.
Blower Doors are used to measure the air tightness and air leakage of building envelopes.
