A new research project in the Building Research Institute aims at developing a quantitative tool for cross ventilation design for buildings. One of the approaches adopted in the project is the experiment in the wind tunnel, where a full-size cubical building model can be used at this stage. In this paper, mainly the first observation result for the building model without openings is shown and discussed.
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.
