11th AIVC Conference - Belgirate, Italy - 18-21 September 1990
The 11th AIVC Conference - Ventilation system performance, was held in Belgirate, Italy, 18-21 September 1990.
Contains 46 papers.
The paper presents results of ventilation characteristics of a lecture/seminar room obtained by various door-window opening combinations and positions, and the level of comfort and air quality resulted by the given window-ventilating modes.
As a consequence of measures required for reducing the heating energy consumption in residential buildings , there have been more and more complaints in the last few years on the appearance of mould in dwellings .
Using pressurization measurements to predict ventilation performance and heating energy requirements of a large industrial building. | 1990 | English
A single whole building pressurisation test using robust and easy to use equipment can, in a very short time, quantify the air-leakiness of the building envelope.
The controllability of room air temperature in different heating systems connected to demand controlled ventilation systems was studied.
Local and room mean ages of the air in a room may be measured by three versions of the tracer gas technique; which are the pulse method, the tracer step-up up method and the tracer decay method.
Natural provision of dwellings with supply air by the "Dortmund Ventilation" system. | 1990 | English
The ventilation system described here combines a central air shaft in the hall area with a mechanical waste air extraction system in the bathroom and in the kitchen.
Reporting guidelines for the measurement of airflows and related factors in buildings. | 1990 | English
A set of reporting guidelines has been established. The guidelines take into account the need for data concerning airflow within buildings and air exchange between a building and its surroundings.
The influence of different ventilation devices on the occupants behaviour in dwellings. | 1990 | English
On basis of several case studies into the ventilation behaviour in dwellings in the Netherlands, it is possible to answer the question whether the type of ventilation device influences the behaviour of the occupants during mild winter periods (5 D
Ventilation system as an air heating system - measuring results in a residential building. | 1990 | English
This paper presents measuring results from experiments with integrated air heating and ventilation system in airtight well-insulated buildings in Stockholm (The Stockholm Project) .
Demand controlled ventilation systems have recently become an interesting opportunity to achieve acceptable indoor air quality while minimizing energy consumption.
This paper describes the techniques used within the ESP system to represent and solve the heat and mass conservation equations relating to combined building and plant systems.
As part of the IEA Research Program Annex 18 "Demand Controlled Ventilating Systems" were tested in a one-family testhouse in relating to energy and ventilating specific aspects.
Building regulations prevailing in France made it compulsory to use specific ventilation systems in new residential buildings since 1969.
Field measurements of ventilation and ventilation effectiveness in an office/library building. | 1990 | English
Mechanical ventilation system performance involves the provision of adequate amounts of outdoor air, uniform distribution of ventilation air within the occupied space, and the maintenance of thermal comfort.
In this paper the required ventilation air flow rates in residences with different pollutant loads are considered. The calculative study was carried out by using the load data presented in the literature.
A simple method using tracer gas to identify the main air and contaminant paths within a room. | 1990 | English
The main air and contaminant flow paths or the spatial distribution of the age of air (or contaminant) in a room are of great interest to estimate the ventilation efficiency performance.
Turbulent flow fields of velocity and diffusion in several types of mechanically ventilated rooms are precisely analyzed both by model experiment and by numerical simulation based on the k-s two-equation turbulence model.
Air change rate and indoor air quality in bedrooms of well tightened residential buildings. | 1990 | English
Measurements of air change rates, carbon dioxide concentrations, room air temperatures and relative room air humidities in bedrooms of five well tightened dwellings were carried out in October 1989.
Presentation of the final report Annex XIV with special emphasis on the case studies. | 1990 | English
The paper summarises the IEA, Executive Committee on Energy Conservation in Buildings and Community Systems, Annex 14 work on Condensation and Energy, a joint research effort of the Federal Republic of Germany, Italy, the United Kingdom, the Nethe
