Case studies

The University of Otago's Property Services division oversees the maintenance of campus buildings and grounds as well as new building construction. As the unit that keeps the University's campuses functioning year round, Property Services' energy use can be intensive. So when they were considering a heating upgrade, one of the key drivers was the ongoing cost of power. Renewable energy was the preferred option. But like any other organisation with limited budget, the final solution needed to make good business sense.

Wigram Lodge installed a wood-chip boiler - and in the process reduced energy costs and improved tenant comfort. Wigram Lodge is saving up to $52,000 and has reduced emissions by 146 tonnes per year.

Rotorua Girls High School requires heating for around 40% of the school year. The school in not only concerned about its enviromental impact but sees a role in providing environmental leadership to its students and the community.

Historically many schools have used coal boilers but particulate and carbon emissions are now being targeted for reduction.

This report details the commissioning and some financials of a moisture meter used by HA Foote Haulage supplying wood chips to Tahuna Intermediate School in Dunedin. A specialist wood chip moisture metering device is used to define the energy content of wood chips HA Foote Haulage delivers.
