VentoVind
™, designed for cold attics, is a system which provides optimised ventilation thereby minimising
moisture-related problems such as mould and rot. This is achieved by
the system's control unit reading off
the climate both outdoors and indoors using sensors, and ensures to only activate the supply air fan
when the outdoor air has a drying out effect. The principle is patented and originally developed at
Chalmers University in Gothenburg, where it was evaluated in practice in several reference
installations that were carefully
monitored. VentoVind™ is a proven technology which has been used for
several years to solve moisture problems in attics in an energy-
efficient way. A big advantage of VentoVind™ is
that the system is suitable for both large and small cold attic spaces, and can be used in houses as well as large
tenement buildings, schools etc. VentoVind™ can be installed both during and after new construction.
A condition for VentoVind™ to function optimally is that the attic space is sealed thoroughly d
uring the
installation so that uncontrolled air exchange does not take place from the surroundings, or that moisture
penetrates from the residence. The aim is that air exchange only occurs through the supply fan and the
ventilation openings that are part of the system, and that the supply fan creates a weak over pressure in the
attic, which prevents humid air from entering the attic space. Depending on the type of fan used, the supply
fan can be speed controlled to always supply the correct level of ventilation. In this way, the ventilation is
optimised to the temporary ventilation requirement and as little energy as possible is consumed.
