The ventilation of a Swedish single family house is investigated by means of tracer gas and pressurization techniques.
Predicted and measured air change rates in houses with predictions of occupant IAQ comfort. | 1994 | English
The purpose of this study was to test an Indoor Air Quality model on a variety of Canadian homes, and use this model to determine the optimal ventilation levels necessary to provide appropriate comfort levels.
A study has been undertaken to (1) evaluate airtightness in recent construction dwellings in New York State, (2) evaluate the effectiveness of various strategies in providing adequate ventilation, and (3) study the use of various ventilation optio
This paper presents a measurement technique to perform quantitative visualization of room air flows.
Occupant satisfaction and ventilation strategy - a case study of 20 public buildings. | 1994 | English
Occupant response in a good indicator of the effectiveness of a ventilation system. In a one-year study in the province of Quebec region, 20 public buildings were studied.
Workers in 'white collar' jobs continue to complain about air-quality' problems.
Single-sided ventilation: a comparison of the measured air change rates with tracer gas and with the heat balance approach. | 1994 | English
In 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.
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.
