Controlling minimum ventilation volume in VAV systems.

Accurately controlling the amount of outdoor air brought into a building is a major factor in ensuring good indoor air quality (IAQ). However, controlling this minimum ventilation volume is difficult  variable-air-volume (VAV) systems.               

Ventilating cold deck flat roofs.

The current recommended minimal ventilation level for the cold deck flat roof design is evaluated using an experimental roof. The work suggests that there may be a need for ventilation to be increased above the minimal level in instances where natural draught ventilation is low or where roofs are of complex plan. Results of this work are under consideration by the British Standards Institution as part of an overall review of flat roof design recommendations.

IEA Annex IX: Minimum ventilation rates and measures for controlling indoor air quality.

From a viewpoint of energy conservation air infiltration and ventilation have to be minimized. A certain amount of fresh outside air, however, has to be supplied to a building in order to maintain healthy and comfortable conditions for theinhabitants and to avoid structural damage. The optimization of these adverse requirements will result in guidelines for minimum ventilation rates which are just large enough to meet the indispensable fresh air demand but small enough to avoid useless waste of energy.
