LoginToday, the development of new technologies to improve building envelope performances ishighly encouraged and provides a clear challenge for designers and researchers. In thiscontext several typologies of active envelopes have become very popular.

A systematic analysis of recently constructed dwellings in the Flemish Region has beenundertaken within the SENVIVV-project (1 995- 1998) [I]. In total 200 dwellings have beenexamined in detail.
Reentrainment of pollutants from exhausted air - discussion of different types of regulatory requirements. | 1998 | English
In many existing ventilation systems unintentional reentrainment of pollutant, due to improper location of exhaust and air intake, decreases quality of indoor environment.
Building performance evaluation for indoor air quality using occupant contaminant inhalation and attribution to contaminant sources. | 1998 | English
The emissions of building materials like volatile organic compounds and indoor airbornecontaminants such as environmental tobacco smoke expose occupants to hazardowsubstances.
Modern passive stack and ventilated schools - evaluation of ventilation and moisture conditions. | 1998 | English
The aim has been to determine ventilation rates and risk of moisture damage in three modernschools with passive stack ventilation.
The present paper discusses issues related to the potential of natuml ventilation techniques whenapplied to urban environment and in particular to buildings located in canyons.
On the time-dependant efficiency of building ventilation on the indoor air quality in a medium sized urban area in Greece. | 1998 | English
From an air pollution study in a medium-sized, seaside town in Central Greece (Volos) it wasfound that some common air pollutants (CO, NO, NOx, SO,, 0,), whose emissions are connectedto activities and conditions that reveal some characteristics of
The Finnish Society of Indoor Air Quality and Climate has prepared a proposal for the classification of the cleanliness of new ventilation systems and components.
Heat recovery in ventilation systems for office buildings in cold climates is necessary for tworeasons:1. To obtain acceptable indoor thermal comfort by preheating of fresh air,2.
Analytical solutions are derived for calculating natural ventilation flow rates in a single-zone building with two openings when no thermal mass is present.
Modelling of indoor pollutant concentrations that varies in time can be a useful tool forestimation of the strength of internal sources and sinks. Usually the modelling has beencarried out using one zone, i.e.
The Swedish Parliament decided 1991 that ventilation systems in all non-industrial buildingsshould be regularly inspected in intervals from 2 to 9 years, shortest for schools, hospitals etcand longest for natural ventilated flats.
Natural ventilation in office-type buildings - results and conclusions of monitoring activities. | 1998 | English
Since the beginning of this decade, natural ventilation in office buildings has been receiving specific interest. There are two sorts of application. Natural ventilation can be a strategy for indoor air quality control.
Experimental impact valuation of fouling on extract air terminal devices performances: an accelerated artificial fouling approach. | 1998 | English
A humidity controlled air flow terminal device works as a humidity sensor : its openingsurface varies according to relative humidity inside a room in order to match air flow rate topollution.
Ventilation strategies for thermal performance improvement of an attached sunspace. | 1998 | English
In this paper ventilation strategies are examined in order to improve the thermal performanceof an attached sunspace of a two-storey semi-detached house in the area of Athens Greece.The ventilation strategies examined are cross and single-sided ve
The Ventilation Standard HASS-102 of The Society of Heating, Air-conditioning andSanitary Engineere of Japan (SHASE Japan) was revised in November, 1997. The title of therevised standard is Ventilation Standard for Acceptable Indoor Air Quality.
Comparison of IAQ performances of French ventilation systems in residential buildings. | 1998 | English
Until now, there is no widely accepted way to express any index for this purpose and takinginto account the large variety of possible pollutants.
This paper gives an overview of the EC NatVent (TM) project on 'Overcoming Technical Barriers to Low Energy Natural Ventilation in Office Type Buildings in Moderate and Cold Climates' which has been carried out under the European Commission Joule
A semi empirical flow model for low velocity air supply in displacement ventilation. | 1998 | English
Similar to supply air jets in mixing ventilation this paper describes a comprehensive flow model for displacement ventilation derived from the integrated Navier-Stokes differential equations for boundary layers.
A self administrated questionnaire was mailed to over 300 dwellings in blocks of flats usingthe wall exhaust. In almost all the dwellings there was a controllable ventilation unit.
