It is recommended to keep the ventilation filters dry. However there are manyventilating systems that cannot fulfil this requirement all the time.

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.

Classrooms in New Zealand schools are mostly low rise buildings with natural ventilationdesigns, sized for summer cooling.

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.

In residential buildings, air-conditioners are usually operated in intermittent mode. Thisintermittent mode may complicate many aspects of indoor environments.

A test room was used to evaluate the impact of airflow parameters on the effectiveness of an air cleaning system. The room’s dimensions were nominally 11.2 m x 5.7 m x 2.7 m.

Emissions from dust collected in air filters have been investigated using in situ and chambermeasurements.

A general trend in intelligent buildings is the decentralization of environmental controlsystems. Decentralized environmental control systems have many advantages over centralizedsystems.

Within an International Energy Agency (IEA) project (Annex 27) experts from 8 countries(Canada, France, Italy, Japan, The Netherlands, Sweden, UK, and USA) have developed toolsfor evaluating domestic ventilation systems during the heating season.

The purpose of this study was to evaluate the indoor air quality parameters in a residentialdwelling using information from the field.

Recently well-insulated and well-airtightened houses are increasing in Japan. Those houses havesome problems of air quality because of formaldehyde from construction materials. Ventilationsystems have possibility to solve these problems.

During the last decade, an increasing interest in Underfloor Air-Conditioning (UFAC) systems has emerged. This is due mainly to an increased demand from employees for a greater control over their working environment.
