Evaluation and demonstration of domestic ventilation systems. VENSET program.

VENSET is a VENtilation Sytems Evaluation Tool for dwellings and is the final result of IEA Annex 27 evaluation and demonstration of domestic ventilation systems.The main idea for this annex was to develop tools to better evaluate domestic ventilation systems in dwellings in various situations. Different systems in various climates must handle situations with a large range of residential behaviour. With the use of the most complex models and development of new ones a large number of combined situations enable us to use simplified tools that can be used by practitioners in specific cases.Various simplified tools are combined in VENSET. It has been developed for three climates : cold, moderate and mild. The tool can be applied on all four main ventilation systems and can also be expanded to other systems by adding one or two extra fans.
