LoginThe purpose of ventilation is to dilute indoor contaminantsthat an occupant is exposed to. In a multi-zone environment such as a house, there will be different dilutionrates and different source strengths in every zone.

Enhancement of cross-ventilation of a detached house using roof surfaces in densely populated urban areas? Part 2 Numerical investigations about the effects of the roof surface use by CFD | 2007 | English
In Part 1, the changes in wind pressure coefficient distributionon the surfaces of the buildings when building coverage is varied are evaluated and identified, and it is elucidated that the ventilation through skylight is effectivebecause the surf
Distribution of a tracer gas in a naturally ventilated greenhouse. measurements and simulations for pesticides dispersion determination | 2007 | English
Numerical and experimental results concerning the emission of a tracer gas (N2O) inside a naturally ventilatedgreenhouse are presented and analyzed.
Multi zone computer simulation is used to predict the concentrations of carbon dioxide, carbon monoxide, formaldehyde and water vapour in a flat and detached house, fitted with five different ventilation systems all of which comply with current bu
Building industry is often regarded as a mature and traditionalsector, in which the technological development is not so accelerated as in other cases.The increasing costs for electric energy, heating and climatization,the dramatic environmental is
An investigation into parameters affecting an optimum ventilation design of high density cities | 2007 | English
For a high density city, given the need to accommodate a fix amount of building volume, what can one do to optimise the benefits of the natural (air) environment?
The effect of plant use on the reduction of volatile organic compounds for environmentalimprovement | 2007 | English
This study aims at examining the reduction of indoor air contaminants by plants placed in an indoor space.Field measurements were performed using Aglaonema brevispathum, which were verified as air-purifying plants by NASA.Two conditions for the am
In mild climates due to the increase of request of comfortof people there is a growing number of installation of low cost and low efficient cooling system even in new buildings.
The scope of the present paper is the presentation of a dynamic and interactive vocational training tool for the implementation of the Directive 2002/91/EC.Certain features of the tool that depend on the existing legislation and restrictions in ea
In Heerlen, the Netherlands, warm and cold water volumesfrom abandoned mines will be used for heating and cooling of buildings, based on a low exergy energy infrastructure.
Measurements of indoor pollutants have been performed in 50 residences in Athens. The concentration of CO2, CO, TVOC’s and PM2.5, PM10 has been measured.
Internal airflow sensitivity in a naturally ventilated atrium subject to variation in external wind conditions | 2007 | English
Design guidelines for natural ventilation in buildings normally focus on the potential hourly air change (ACH) rates based on the building space parameters.
The use of windows is a key adaptive opportunity in naturally ventilated buildings especially in summer when the building is likely to be free-running.
The primary aim of the EP label project was to develop a methodology for energy benchmarking and certification of buildings, based on Operational Ratings, to address the EPBD Article 7.3 requirement for Public Buildings over 1,000 m to display an
Methodologies to bring innovative environmental technology R&D results into the market | 2007 | English
It has been widely recognised that too few projects initiatedunder both national as well as EU funded research projects find their way to commercial exploitation.
The paper deals with applicability of passive and low energy cooling technologies in the Czech Republic.In the paper there are presented two recent studies, where computer simulation helps to design properly the passive and low energy cooling for
Estimation on the effectiveness of the crossventilation as a passive cooling method for houses | 2007 | English
The integration of research outputs on the cross ventilation is tried in order to quantify the reduction of cooling energy, by raising the stepwise questions and by reviewingexisting knowledge useful to find solutions.
