Case studies

The University of Auckland now uses 41% less energy per student than it did in 1981, thanks to careful energy management. The university has achieved the reduction by continually monitoring its energy use, and using the results to identify and introduce targeted energy-efficiency measures.

Those measures include large-scale projects, such as upgrading the heating system, as well as low-cost initiatives such as introducing automated computer shutdowns. They are estimated to have saved the university more than $100 million since 1981 (based on 2008 energy rates).

This case study features a solar water heating installation at Solscape, an eco retreat near Raglan. Hot water is what tourists expect from the moment they unpack their suitcase and Solscape are using the sun's rays to solve this.

At Kopua Holiday Park in Raglan they can't always guarantee that the surf is up, but they can offer the sun on tap. That's because they've installed a large scale solar water heating system on their main kitchen and ablution block that delivers plenty of hot water when it's needed.

All public sector organisations have the opportunity to be leaders in the use of energy efficient technologies.

This case study describes a solar water heating initiative undertaken by Landcare Research which has the potential to be replicated by other government entities throughout the country.
