Volume content
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…
A new multizone airflow and contaminant dispersal model CONTAM93 is described, along with a demonstration of its application in a study of ventilation and…
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…
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…
Ventilation of the void below suspended timber floors is necessary to prevent dampness, which leads to wet and dry rot. The air flow beneath such a floor…
The aim of this study was to unravel the occupational exposure to radon among underground workers. The possibility for radon mitigation by improving…
Proper dimensioning of natural ventilation system for multi-storey buildings is a critical matter, because the air flow rate depends on many parameters as…
After a short description of the physical phenomena involved, unified expressions are worked out describing net airflow and net heat flow through large…
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 UK factory stock is predominantly naturally ventilated. Measurements performed in this class of building have indicated that air infiltration rates in…
Mechanical ventilation of the underfloor space is one of the most effective ways of reducing radon levels in buildings with suspended timber floors. There…
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 reason for the present project is the need for more reliable information about the actual ventilation conditions in naturally ventilated, detached…
The adequate ventilation of houses is essential for both the occupants and the building fabric. As air-tightness standards increase, background infiltration…
In order to demonstrate conformity with the current Building Regulations, many house builders are incorporating sumps beneath the ground floor construction…
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…
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…
BRE have experimental data for the flows found in Passive Stack Ventilation (PSV) ducts from a test house in Garston. These data cover different duct…
The paper summarises an approach to determining the equations governing the air flow through simple cracks subject to fluctuating pressures. To this end, an…
The "Passivhaus Darmstadt-Kranichstein" is a 4 unit terrace house with an extremely low total annual energy consumption of less than 32 kWh/m² of living…
