Horizontal distribution of submicrometre particles from vehicle emissions near a major road: implication for building location. | 1999 | English
Natural devices in the urban spaces to improve indoor air climate and air quality of existing buildings. | 1999 | English
The role of outdoor spaces’ design as well as the mutual correspondence among urban microclimate, indoor air climate and air quality, have been specifically investigated for the case study of the Central Athens Area.
Suitable combinations of desiccant and evaporative cooling systems permit air processes alternative to the traditional ones for air conditioning applications.
Isolation rooms for Tuberculosis in fifteen hospitals have been surveyed and measured in twophases. In phase 1 the isolation rooms in seven hospitals were checked ater the hospitalsrenovation construction had been finished.
Design of ventilation routes and indoor air quality in houses using a passive ventilation system. | 1999 | English
The feasibility of designing ventilation routes in the house with passive ventilation system is investigated using the numerical experiments and the measurements on its ventilation rates and indoor air quality.
Design methodology and economic evaluation of central-fan-integrated supply ventilation systems. | 1999 | English
Residential ventilation systems can be categorized as supply, exhaust, or balanced systems.This effort focused on establishing a design methodology for central-fan-integrated supplyventilation systems.
Hybrid air conditioning based on natural and mechanical ventilation in office buildings. | 1999 | English
The performance of a hybrid air-conditioning system which utilises wind-induced cross ventilation is investigated.
Comparisons of microorganism loading from two air filter materials during the first eight weeks of service life. | 1999 | English
As part of an ongoing investigation on service life of air filtration material, a new type of airfiltration material (multi-layered polymer) was compared with a widely used material todetermine growth or survival of micro-organisms after normal du
The effect of surrounding ground conditions and ventilation rates on the internal environment of traditional excavated dwellings in Santorini, Greece. | 1999 | English
This paper deals with the internal environment of traditional excavated dwellings in Santoriniand the effect the conditions of the surrounding volcanic rock have on it.
Destruction of VOC using photocatalyst under UC light irradiation - the influence of UV wavelength on mineralisation. | 1999 | English
Avariety of gaseous pollutants in indoor air now are becoming an object to control.
Forced air furnaces are a common Canadian heating system. Traditionally, filters placed in thecirculating air ductwork were designed to protect the furnace and fans.
The Building Components Technology Department of ICITE, the Central Institute forIndustrialization and Technology in Building of the Italian National Research Council hasstarted an experimental research on natural controlled ventilation devices.To
Factors influencing effectiveness of ultraviolet germicidal irradiation for inactivating airborne bacteria: air mixing and ventilation efficiency. | 1999 | English
As a result of the recent resurgence in tuberculosis incidence, there has been increased interestin using ultraviolet germicidal irradiation (UVGI) of room air to reduce exposures toinfectious agents.
Formaldehyde (FA) adsorption, including that in the presence of water vapours, has been evaluated on adsorbents of various nature and porous structure.
Experimental measurements and characteristics of the supply air "ventilated" window. | 1999 | English
A currently unresolved problem in building design in the paradox between increasing demand for good thermal insulation, and the requirement for ample levels of ventilation, to maintain a healthy indoor environment.
Effects of ultraviolet germicidal irradiation of room air on airborne bacteria and mycobacteria. | 1999 | English
As a result of the recent resurgence in tuberculosis (TB), there has been renewed interest inengineering controls to reduce the spread of TB and other airborne infectious diseases in highrisk settings.
It is recommended to keep the ventilation filters dry. However there are manyventilating systems that cannot fulfil this requirement all the time.
Numerical determination of the effective depth for single-sided natural ventilation. | 1999 | English
This paper describes a numerical method for the determination of the effective depth of fresh air distribution in rooms with single-sided natural ventilation. The numerical method involves predicting air flow and the local mean age of air.
Indoor air quality in museums and historical buildings in St Petersburg and in north-west region of Russia. | 1999 | English
This presentation deals with the problem of achieving stable microclimate in old buildings ofSt Petersburg - such as churches, museums and palaces.
Indoor air quality is decreasing year by year. It is very necessary to find a kind of efficient cleaner to improve the indoor air quality. Two kinds of cleaners were tested. Both of them were made in China. Four simulated chambers were used.
