Sustainable recommendations for the faculty of technology of the University of Brasilia - Brazil | 2007 | English
The aim of the Pythagoras project was the development of an innovative national training material in the sector of indoor environmental quality.The need for education in this specific sector is dictatedby the significant indoor environment deterio
Exergetic evaluation of high-temperature radiative cooling combined with natural ventilation | 2007 | English
This paper describes the possibility of high-temperature radiative cooling combined with natural ventilation.
It is difficult to design indoor environment under natural ventilation because there is insufficient knowledge to evaluate the effect of the natural ventilation space quantitatively.Especially, natural ventilation rate is not yet fully understood.
Analyzing air-tightness measurements using fan pressurization method on forty residential houses in Athens, Greece | 2007 | English
Regular air tightness and infiltration measurements were performed in forty houses, in the area of Attica, Greece. Two measurement methods were used, the tracer gas decay method and the Blower Door tests method.
Temperature, relative humidity, pressure difference across the floor and microbial concentrations were investigatedin the four buildings which had either concrete floor (1 piece) or wooden floors (3 pieces) and crawlspaces.The temperature followed
In this article, the first part of a research project about the modelling of a solar chimney is presented.
It has been investigated the effect of different construction parameters to the thermal performance of a solar chimney.These parameters are the thermal resistance of the walls, the glazing type and the solar chimneys thickness.The thermal performa
Estimation of the main thermal parameters of a real size solar chimney from outdoordynamic tests | 2007 | English
The growing energy consumption for cooling of buildingsis one important concern in Mediterranean countries.Natural ventilation plays an important role as passive energy saving strategy, regarding cooling of buildings in this climate.
Little floors town-planning complexes with energy protect building systems and new types concrete in Russia at 2007 | 2007 | English
Research of adaptability to manufacture of application of designs from porous concrete with the help of methodsexpert estimating has shown a high level of adaptabilityto manufacture of the developed decisions in view of factory, transport, assembl
The 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.
Methodology and results of construction company R&D department in energy efficiency in building | 2007 | English
To promote the sustainability the building environment is full of opportunities; in particular in Europe with the energy building performance directive and its adaptationin Spain with the new regulation on energy efficiencyin building (Cdigo Tcnic
A Study on the indoor air quality management effect of intelligent building certificationdrogram | 2007 | English
The management of indoor air quality is accomplished by various types of complex mechanisms related to indoorenvironment and recently, an integrated solution applying state of art technology is being presented pertainingto the management of indoor
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
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.
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
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?
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.
