Waitaki Boys High School, as the second oldest school in New Zealand, faced unique challenges in heating its premises efficiently. The project aimed to integrate advanced technology solutions to enhance air quality and energy management within the school’s multiple buildings, aligning with New Zealand’s focus on healthy learning environments, while also preserving the integrity of its heritage buildings.
The main opportunities included controlling an outdated heating system, improving air quality, and integrating a comprehensive building management system. There was a significant need for technology that could link air quality sensors with the building management system, as the school’s existing electrical system only included basic meters.
IQnexus is strategically located in New Zealand between
Asia Pacific, Australia and South America. Our purpose is to facilitate digital transformation and the implementation of sustainable technologies for the region.
IQnexus is part of the Brunata-Minol-ZENNER group, a German consortium whose roots can be traced back over 100 years and began with the development of devices for recording energy consumption.
Led by IQnexus, the project saw the integration of Optergy’s advanced P864 controllers, which played a crucial role in managing the heating systems and CO2 sensors across the school. These controllers enabled the effective management of an older boiler system and laid the groundwork for future upgrades to more sustainable heating solutions. The project also involved installing energy meters and leveraging Optergy’s versatile ‘Lego block’ approach. This allowed for an open and adaptable system, capable of interfacing with products from other companies like Thermokon.
The layout comprises multiple buildings, constituting a large-scale installation. One of the educational aspects for the school staff was understanding the type of data available and how to utilise it effectively.
Specific Applications:
The project incorporated 64 CO2 sensors, along with VOCs, and temperature and humidity sensors. Each building was equipped with a P864 unit, allowing for comprehensive monitoring and control of the heating systems and air quality.
