The air flow pattern ATLAS - a reference book of computed flow fields.

The first version of this "Atlas" contains over 100 cases of office air flow patterns for different ventilation systems. The book is designed to give the design engineer a quick idea of how a particular system works under various loads. Maps have been prepared for velocity, temperature, turbulent kinetic energy, percentage dissatisfied due to draft risk, and pollutant concentrations (caused by a smoker, bookshelf, or by building materials).

Modeling and predicting of pollutant transfer in multizone buildings coupled with ventilation networks.

A literature review shows that the actual trends to prediction of air flow in multizone buildings are not only due to economical reasons but mainly to indoor air quality, acoustical and thermal comfort improvements. During the last decade, almost fifty models have been developed in eight countries [1]-[4]. Except some models the analysis of interaction between HVAC systems and building infiltration is seldom studied [5].

Operation of passive stack systems in summer.

The ventilation rate in a building depends on many things, one of which is the air temperature. The air temperature in turn depends in part on the ventilation rate. The effects of this relationship are generally overlooked in both thermal and ventilation models. To study this effect a model has been developed which integrates the models GAINE and SILONA developed at CSTB. This allows the prediction of the natural ventilation rates caused by the actual temperatures in the building.
