In a displacement ventilation system a thermal plume which is formed over a heat source evokes circulation flows, thermal stratification of the room air and air transport from the supply to the outlet opening. The results of experiments on plu

Interim report giving results of measurements on thermal environment and air tightness of a scale model experimental atrium carried out from February to April 1994.

This article describes the integration of a gas engine-driven heat pump system in the air conditioning and heating system of the World Trade Center premises in Amsterdam. The heat pump provides for both cooling and heating during the summer and winter periods and also provides emergency power in the case of interrupted public power supply.

The stack effect provides the driving force for vertical air movement within buildings. Its effects are especially pronounced in high rise developments, where the air leakage associated with elevators, stairs and service shafts can be a major concern. Stairwells and lift shafts themselves provide occupant access to those floors above or below ground level as well as providing routes for the movement of air. A knowledge therefore of the air movement characteristics if such shafts is vital in understanding the ventilation and leakage patterns in medium and high rise buildings.

Summarises research into the positioning of air intakes to avoid contamination of ventilation air. Based on current research, it attempts to demonstrate various ways in which the pollution at air intakes can be minimized at the design stage. Also doe those buildings which have become polluted, it discussed what actions are than available to reduce the contamination of the indoor environment.

Provides a platform for the dissemination of information related to infiltration, ventilation, indoor air quality and energy use within buildings by means of a survey and analysis of current research. The current survey reports on research projects from over 250 sources worldwide. The sections include an analysis of the results of the survey, a detailed list of survey replies, which is also available in searchable database format, and contact names and addresses for researchers.

An introduction to the Internet which illustrates the range of information available and shows hoe in a short time it is possible to become connected and operational on the Internet. The services offered include e-mail, the ability to tap into vast sources of data, and the opportunity to establish one s own information databases for either general or restricted access. Energy efficiency related homepages include the US DOE CADDET and various IEA programmes and annexes.
