Remarkables Primary School

The newly built enviro-school is amongst the most technically advanced schools in New Zealand that fully integrates with the surrounding landscape. Set between Lake Wakatipu and The Remarkables, this primary school is situated on one of the most sought after spots in Queenstown.

The Challenge

While the setting of the site is spectacular, it is approximately half the size of a typical primary school site. However, the gross floor area of the school is 3030m² which includes 1820m² of classroom space. A large environment to heat, cool and ventilate, with different areas having different needs, control was also a major consideration.

The school is also located in close proximity to the Queenstown International Airport. With Ministry of Education requirements stipulating that acoustics of learning spaces must be under 35dBA it would require quiet equipment to ensure that the environment was kept at regulation sound as aircraft noise at boundary level is around 90dBA.

The Solution

In order to service the needs of the whole building, 200kW of Mitsubishi Electric R2 simultaneous heating and cooling has been installed. Lossnay fresh air ventilators provide fresh air to each of the classrooms and the administration block. In order to address the noise, Lossnay units were fitted with noise attenuators, and the main indoors units are PCFY under ceiling units, and PLFY cassettes.

The school also has an AG150A with two expansion controllers, controlling all of the air conditioning and Lossnay systems. A DIDO module has also been installed to allow the AG150A to time schedule the toilet extract fans. The AG150A has a floor plan loaded in for each of the classrooms and administration block to create a small BMS.

There is also a small pre-school located on this site which is independent of the school, but still fitted out with Mitsubishi Electric split systems.
