Case Studies
Energy Solutions has worked with a large number of different organisations. Here are just a few of their stories:
Massey University
Energy Solutions has been working with Massey University for a number of years. At the end of 2004 Massey contracted Energy Solutions to provide an energy audit of the East Precinct of their Albany campus.

Seven buildings were audited (a total of 26,000 sq.m). During the audit we worked with facilities management staff and contractors to identify energy cost savings of 35%. There was potential for an additional 18% savings, which would require more work to confirm.

We identified 28 different energy saving measures ranging from using occupancy and motion sensors to changing drive belts on air handlers to removing excess lamps to adjusting temperature set-points.
"We are very impressed with the way Energy Solutions performed the Energy Audit and the subsequent comprehensive reports produced. The saving opportunities and recommendations identified in the reports are now being put into practice. I have no hesitation in recommending Energy Solutions Ltd in performing Energy Audits."

Ports of Auckland
In mid-2005 Energy Solutions conducted an energy audit of the Ports of Auckland.

The major energy consumption was from the refrigerated containers stored on site while in transit. The floodlighting was also a significant energy user. A major project where the floodlights were replaced meant the number of lamps, and resulting energy use, could be cut in half. Of the buildings on site we were able to find energy cost savings of 15%.

Perhaps the most useful outcome of the audit was the analysis of where the energy was used on site. It revealed some interesting performance statistics about the operation of the 8 large cranes and uncovered just how much energy the refrigerated containers really used.
Te Papa
Energy Solutions has been an integral part of the Energy Management team at Museum of New Zealand Te Papa Tongarewa for many years. Following an extensive energy audit and on-going consultation, Te Papa has now contracted Energy Solutions to optimise the performance of its heating, ventilation and air-conditioning (HVAC) system.

The project is due for completion in early 2006. After detailed monitoring of the operation of the HVAC System, several control strategies have been identified as potential energy saving measures.

The next phase of the project is to execute the energy efficiency improvements.
Victoria University of Wellington
During 2003/04 Energy Solutions completed energy audits on 17 of Victoria University's largest buildings.

Following on from those audits, Energy Solutions was then contracted to manage the implementation of the most cost effective energy savings measures. Over a few months 30 individual projects were organised on behalf of the University.

Some of the projects were very quick and simple solutions, while others took more time and co-ordination. Over $60,000/yr of energy cost savings were captured from the project all at under a one-year "payback". The energy savings included installing time clocks, changing control settings, daylight switching, removing excess lamps and much more.
"The energy audits were useful from many perspectives. The benefits extended beyond the direct savings through energy reductions by identifying efficiencies in maintenance and general 'housekeeping' that would otherwise have been overlooked. The energy projects themselves were executed extremely well by Energy Solutions with a significant amount of work being done outside normal working hours to minimise disruption to students."

Tauranga Art Gallery
In 2004 Energy Solutions provided Design Assistance for the proposed Tauranga Art Gallery - a building intended to be very energy-efficient, while maintaining valuable artworks under archival conditions.

The specifications of the building were checked by Energy Solutions to ensure that specified building controls were well documented, energy efficiency of specifications were maximised and efficient practices for monitoring energy use and building conditions were maintained.

We also used building energy simulation software (EnergyPlus) to determine the savings potential of variations to the specified lighting design, building fabric, HVAC plant and building controls.

The improved design strategy generated energy savings of over 30% compared to a simulated model of the building originally specified.
"It was good to have a second opinion on the design and performance of the proposed HVAC system for the building. Energy Solutions overall evaluation of the energy efficiency of the building was important as high energy costs will eat into our exhibition budget."
