An energy balance over an urban area and over a rural one, reveals that the first case is always more complex than the last one. The urban context is able to change all the energy transferences mainly due to its own layout. Thus, analysing all the energy transferences one by one, we can find how they affect in a different way depending on the surroundings, among other influences.

The aim of this paper was to examine the effect of two different dust collection devices, widely used in epidemiological studies. The device used for dust sampling has a significant influence on the amount of dust collected and may lead to uncertainty in the measurement of biomarkers.

This paper provides scientific evidence that electrified homes in South African rural villages have lower levels of air pollution compared to the non-electrified homes using fuel or wood. The measured air pollutants were RSP (stationary respirable particulate matter), the CO in the kitchen and the CO on the child.

The aim of that study was to compare measurements of wall relative humidity (RH) to mold identification in 458 samples from 100 dwellings. The mold identification was made by a direct microcospic examination of a sample collected on the wall by means of the gummed paper technique. The conclusion of that study was that a simple measurement of wall RH is a reliable index for suspecting S. Chartarum infestation in a dwelling.

The purpose of that study was to measure exposure levels of phthalates and musk fragrances in typical apartments, kindergartens and to estimate their effects on health. 59 apartments and 74 kindergarten in Berlin were studied.

A pilot questionnaire study was carried out on two groups: 128 occupants of new homes' (52 R-2000) on the one hand and 149 occupants of control homes on the other hand: both the groups were questionned to compare their general and respiratory health at occupancy and one year later. Symptom scores improved significantly over the year of occupancy for the occupants of energy efficient homes.

Re-number k-e model is the most used turbulence model in Computational fluid dynamics. But sometimes that model does not produce good results and Reynolds stress model (RSM) improves the prediction of the velocity in the jet. Measurements and observations of streamline patterns prove it.

This paper deals with a pilot study in portable classrooms where neither adequate ventilation nor associated conditioning of indoor air for occupant comfort were provided. Concentrations of pollutants should be mitigated with an appropriate ventilation and should lead to a reduction of symptoms of "sick building syndrome"

This paper deals with a modeling approach that combines the classical heat and moisture balance differential equations along with the use of experimental time-series data. This approach provides an ideal form for advanced model-based control system design.

This article aims at providing an overview of recent field experience, as reported in the literature, about underfloor air distribution systems (UFAD) as an alternative to conventional air distribution.
