Air distribution solutions to lower air velocities and good temperature control are studied in that paper. Measurements and temperature simulatins were carried out in 6 schools.

For that paper, used supply air filters have been studied by sensory and chemical methods. Thermodesorption/cold trap (TCT) and headspace (HS) devices were used too to examine the filter dust. Results and conclusions are presented.

A numerical study has been done to determine the effect of the perimeter heating load on the air diffusion performance iindex (ADPI) of an air diffuser for different air flow rates and different heating loads.

A model for displacement ventilation prediction based on plume rise of single point heat source was developed for that study. Numerical and experimental data are compared .

Airflow measurement techniques are necessary to determine the most basic of indoor air quality questions: "Is there enough fresh air to provide a healthy environment for the occupants of the building?" This paper outlines airflow measurement techniques, but it does not make recommendations for techniques that should be used. The airflows that will be discussed are those within a room or zone, those between rooms or zones, such as through doorways (open or closed) or passive vents, those between the building and outdoors, and those through mechanical air distribution systems.

Gives an extensive list of literature on the topic and provides a detailed analysis of several aspects of the problems which can occur. States that good ductwork design and installation are key to providing well balanced ventilation systems, and lists a number of fundamental handbooks which carefully outline the essential elements of designing ventilation air ductwork. Describes various methods including the constant velocity method, the velocity reduction method, the equal friction method, and the static regain method.

This bibliography is aimed at those building professionals who are looking for an overview of current developments in duct cleanliness and design. The quality of the indoor air depends as much on the cleanliness of the equipment and ductwork it passes through before reaching the occupied space as it does on the quality of the outdoor environment. This bibliography will review the sources and types of contamination found in ventilation ductwork, including dust, oil residue, fungal growth, and chemical emissions.

The aim of this bibliography is to review and technically assess research into the impact of urban air pollution on the indoor environment. It includes a brief summary of relevant technical papers on the subject and lists those papers with accompanying bibliographic details.

This bibliography outlines the main features and design considerations of passive cooling ventilation systems. It draws on current research and case studies to provide a comprehensive and authoritative review, dealing with the prevention of heat gains (through location, landscaping, building morphology, shading and other solar control techniques); the modulation of heat gains (by thermal storage and night cooling) and heat dissipation methods (using natural ventilation, radiative cooling, evaporative cooling and earth cooling).

Gives an overview of current developments into acoustic control within buildings and their impact on current ventilation practices. Includes an examination of current design guidance and advances in acoustic measurement and calculation, as well as research into noise generation and control in buildings, with the emphasis on both noise transfer by the building itself (structural elements, design or occupants), as well as HVAC generated noise (including noise transfer from the plant room, ducts, terminal devices, etc).
