Episode 14 :: Low cost ways to save energy
EECA’s experience working with companies that have energy audits, show that typically 10% of energy can be saved through no- and low-cost changes – i.e. actions that will pay for themselves within a year.
The Novotel hotel in Ellerslie was the first in the chain to undergo an energy audit. It found several low-cost ways to save energy, including motion sensors for lighting and devices to manage hot water use. All the measures implemented paid for themselves within a year. All Novotel hotels in New Zealand now have energy-saving programmes as well as silver certification under the Green Globe environmental certification scheme.

Many of the most common areas of energy consumption can be controlled and reduced with little or no up-front cost. There are low-cost ways to cut the energy used by lighting, equipment, heating and air conditioning, hot water and transport.

For many companies, an energy audit is the best way to kick-start an energy management programme because it delivers comprehensive, independent advice on where the energy savings are. While a lot of energy can be saved through a common-sense approach and behaviour change, it often takes an energy expert to locate the worst areas of energy waste and recommend the most cost-effective way to tackle it.
EECA’s analysis shows that for every $1 invested in an energy audit, typically $7.50 worth of savings are identified. Most companies can save on average, 20% of energy costs:
- 10% through no and low-cost changes (payback of 12 months or less)
- 10% with some investment (payback of 1 – 5 years).
Energy saving in tourism
Tourism-related companies often have a lot to gain from energy efficiency and / or renewable energy, as overseas consumers are increasingly aware of their environmental impact. As a result, the sector has been in the advance guard of New Zealand businesses tackling energy efficiency.
The Tourism Energy Efficiency Programme is a joint initiative between EECA and the Tourism Industry Association. It involved mentoring a number of businesses through an energy audit and saved participating companies an average of 15% in energy costs.
