What's the job really like?

Energy Auditor

Energy auditor Adam Marsh investigates a building's energy use, and looks for ways to make it more efficient.

What's an energy audit?

"The audit process is about finding out how energy is used in a building as a whole, and finding ways to improve it. You're going to look at your biggest energy users first, such as the air-conditioning and lighting."

What happens after the audit?

"Once the audit's done, we compile the information and assess the best way to reduce energy use in the building. We then present our findings to the customer in a way that is easy to understand."

Why is this sort of work important?

"Energy consumption is becoming more of a concern and people are becoming more aware of how much energy they use and the environmental issues that surround it.

"New Zealand can be completely sustainable if it wants to. Obviously New Zealand has advantages, like having hydro and geothermal capabilities, and enough generation ability to cover the population, but to become the first country to be totally sustainable would really put New Zealand on the map."
