Outline of Hybvent.

The international project Annex 35 "Hybrid ventilation in New and Retrofitted Office Buildings was accepted by the IEA at the Energy Conservation in Buildings & Community Systems Executive Committee Meeting in Washington June 1 997. The first year, starting August 1 1997, was a preparatory year and the four year working phase started August 1 998. The Annex have participants from 1 5 countries: Australia, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Italy, Japan, Norway, Sweden, The Netherlands, United Kingdom and USA.

Two air flow studies completed.

Discusses two completed annexes of the IEA Energy Conservation in Buildings and Community Systems Programme, Multi-zone air flow modelling, and Energy efficient ventilation of large enclosures. For the former, it considers the tasks, the algorithm, the user interface, numerical reliability, evaluating potential user difficulties, comparing numerical predictions with experimental data, outcome and conclusions. For the latter, considers background and objectives, the tasks, the design principles guide, analysis and prediction techniques, case studies and outcome and results.
