Case studies

Southern Lakes Laundries has installed a high-efficiency heat exchange unit for their main industrial washing machine that is delivery savings of up to $45,000 a year.

Southern Lakes Laundries retrofited the heat exchanger into their existing equipment without any disruption to their 364 day a year operation.

The project payback period is approximately 2 years.

During the design phase of Waitakere Hospital a design audit was undertaken to ensure that the new facilities were low-energy environments. Adjustments were made to the design so that the buildings made the most of natural ventilation, insulation and natural lighting levels were increased as well as the use of other energy efficient technologies.

An energy efficient all-in-one system that integrates air
conditioning, freezer and coolroom control and water heating in a compact rooftop shed evolved from a partnership between a fast food chain, an air conditioning company and an energy efficiency company.

An energy audit across its 27 dairy farms gave Landcorp Farming an insight into technologies to save energy and money. The resulting changes have reduced energy use by 9% and saved more than $50,000 in energy costs per year.
