Both installations allow the attraction to minimise its impact on the environment by using virtually no energy to ventilate the buildings, benefitting both the local environment and reducing long-term running costs for the business.

The WINDCATCHER X-Air is a 2nd generation natural ventilation system featuring the patented ACTIVLOUVRE® modulating aerofoil louvre technology. The system consists of an external static louvre and internal active louvre arrangement, which varies the opening and free area through the louvre face.  In addition to the ACTIVLOUVRE arrangement, the system also incorporates external air catchment fins to provide greater area at the louvre improving performance in relation to wind speed. Pressure release vanes at the fins provide a means to reduce face pressure under high winds.

When coupled with Monodraught’s iNVent control system, the system is capable of providing temperature and CO₂ demand controlled ventilation, by means of energy efficient motorised volume control dampers.
