This project was carried out on a design - build basis for the client. As one of the largest Netball clubs in Auckland, Netball North Harbour had a need for a purpose built all weather court facility to promote the development of its senior players. The initial proposal was for a smaller facility but as more funding became available the structure grew in size and sophistication. Initially intended to cover existing artificial turf courts the project was expanded to cover a wooden sports floor and along with this came some significant design challenges. Main concerns were condensation and humidity both of which would be disastrous for a high quality wooden floor. Designing and installing an interior mesh lining, creating an effective air barrier between inner and outer surfaces of the structure addressed these challenges. To make this work ventilation was the key and a low cost passive ventilation system was developed around a series of large roof vents to allow a free flow of air through the structure. The ventilation system has been particularly successful in maintaining temperature and humidity levels within the desired range. The unique design has also ensured that the pavilion remains weather tight even in severe weather conditions.
