LoginThe reason for the present project is the need for more reliable information about the actual ventilation conditions in naturally ventilated, detached houses.

Investigation of ventilation conditions in naturally ventilated single family houses. | 1994 | English
The fan and the ductnetwork is designed for 100% ventilation rate. Because the fan energy is the main important energy consumption in systems all over the year it is worthwhile to control the systems correctly.
The adequate ventilation of houses is essential for both the occupants and the building fabric. As air-tightness standards increase, background infiltration levels decrease and extra ventilation has to be designed into the building.
Role and tasks of ventilation in modern buildings: a case study for Silesian dwelling houses. | 1994 | English
The paper presents some selected results of evaluation of improvement effectiveness of thermal insulation and tightness of multifamily dwelling houses located in the region of Silesia.
Ventilation concept, indoor air quality and measurement results in the "Passivhaus Kranichstein". | 1994 | English
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 area, thereof about 12 kWh are needed for room heating /Feist 1994/.
A measurement system is described to record the movement in a room of neutral density balloons or bubbles, and thus the movement of air in that room.
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 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.
