Temperature and relative humidity have been measured in a BRE test house to investigate the vapour content in the void beneath the timber floor. The void can be ventilated naturally or by means of a fan supplying or extracting air.

With increasing demand for acceptable indoor environment it is necessary, already in theconstruction phase, to estimate what effect different environmental factors have on theoccupants.
Nilsson H, Holmer I, Holmberg S
A secondary analysis of the Dutch prevalence study by Zweers et al shows that office buildingswithout artificial cooling and with operable windows have a lower risk for health symptoms andcomfort complaints than office buildings with artificial co

House-dust mite antigens are a major contributor to allergic sensitisation. Since temperatureand humidity are crucial to house-dust mite physiology, there is considerable interest inreducing mite populations by controlling the indoor environment.
Crowther D, Oreszczyn T, Baker N, Pretlove S
Three very different task/ambient conditioning (TAC) systems were investigated in a climate chamber.
Tsuzuki K, Arens E A, Bauman F S, Wyon D P
Until now, there is no widely accepted way to express any index for this purpose and takinginto account the large variety of possible pollutants.

The aim of this research is to apply dynamic Large Eddy Simulation (LES) to predicting the complex turbulent flow field in an air-conditioned room.

The purpose of this paper is to evaluate the performance of four kinds of ventilation systems from the point of view of air exchange, indoor air pollution, and space heating load under Japanese conditions by numerical simulation.

Recent years have brought the popularity of methods in which neutral networks are applied. They seem of particular importance while dealing with diagnosing, predicting and estimating.
Piotrowski J Z
Results are presented from a study of the performance of fuzzy, rule-based algorithms for thecontrol of indoor air quality through combined control of natural and forced ventilationstrategies, whilst simultaneously meeting thermal and visual comfo

Investigation the modelling of the mathematical model of expediency of project decisions of building materials including the human safety the asbestos. The asbestos is most widely used in the production of roof cover-slate.
Krutkeviciute O, Viliunas G
In laboratory experiments, we investigated the ability of two task/ambient conditioningsystems with air supplied from desk-mounted air outlets to efficiently ventilate the breathingzone of heated manikins seated at desks.
Faulkner D, Fisk W J, Sullivan D P, Wyon D P
The paper presents results from the numerical modelling of the flow field in an existing ventilated office room.
Stankov P, Denev J, Stamov S
Particle deposition from turbulent duct flow is modelled and related to particle penetration of a ventilation system for a commercial office building.
Sippola M R, Nazaroff W W, Thatcher T L
The effectiveness of ventilation related to the two primary tasks of ventilation, (I) the supply of fresh air, and (ii) removal of contaminants, is investigated.

In the beginning of 1998 the European project, AIRLESS, was started to develop strategies,principles and protocols to improve and control the petiormance of HVAC-systems and itscomponents for the incorporation in codes and guidelines.

The necessity to provide and maintain high cleanness of air in the rooms of the highestcleanliness classes requires a proper adaptation of selection and designing methods for airfilters.
Charkowski A
It is the objective of the present paper to investigate indoor environmental characteristics ofan office building with an underfloor air conditioning system.
Han H, Chung K S, Jang K J
In order to evaluate the impact on indoor air quality of different installation and ventilation strategies, the modelling of indoor air pollutant transfer has been developed in the CLIM2000 software (thermal and airflow code).
Parey S
The influence of natural convection on the thermal properties of insulating porous medium with air cavity is studied.
