LoginIn the frame of the European PASCOOL project, several experiments regarding single sided ventilation were carried out at BBRI in the outdoor PASSYS test cel. The test room of 30 m³ has a vertical window of about 1 m².

Single-sided ventilation: a comparison of the measured air change rates with tracer gas and with the heat balance approach. | 1994 | English
This paper reports on the findings from two extensive laboratory studies of ventilation of bathrooms of different sizes and layout of ventilation. The ventilation flow rates were varied.
Ventilation of the void below suspended timber floors is necessary to prevent dampness, which leads to wet and dry rot.
Effectiveness of various means of extract ventilation at removing moisture from a kitchen. | 1994 | English
A kitchen is one of the major moisture producing areas in a dwelling. In order to prevent condensation and mould growth the relative humidity should not be too high.
This paper shows preliminary results of 18 out of 30 inspected ventilation systems in low rise, low energy residential buildings. We propose a method for the assessment of energy efficiency of ventilation systems.
This paper briefly reviews the weather data available for natural ventilation and briefly reviews hourly data for simulation. It starts by reviewing the need for basic data for initial manual calculations.
Passive ventilators in New Zealand homes: Part 1: numerical studies and Part 2: experimental trials. | 1994 | English
New Zealand homes have traditionally been ventilated through open windows and by background infiltration.
The paper summarises an approach to determining the equations governing the air flow through simple cracks subject to fluctuating pressures.
Terminals are used on all types of ventilation system exhausts, often to prevent rain water and animal entry, but also to prevent wind induced flow-reversal and enhance wind induced updraught.
Numerical assessment of thermal comfort and air quality in an office with displacement ventilation. | 1994 | English
Computational fluid dynamics has been used for assessing the thermal comfort and air quality in an office ventilated with a displacement system for a range of supply air conditions.
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.
The use of PSV (Passive Stack Ventilation) systems in two and three storey dwellings is now widely accepted as a method of achieving adequate ventilation levels for indoor air quality control.
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.
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 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.
BRE have experimental data for the flows found in Passive Stack Ventilation (PSV) ducts from a test house in Garston.
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 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.
