Auckland Council
Challenge
Managing 3,500 properties with a wide range of uses, distributed around Auckland with a small team is a huge challenge for Auckland Council. However with energy efficiency targets to meet the Council team needed to focus on achieving and sustaining gains through partnership.
Solution
The ESP energy and water monitoring solution was implemented at nearly 100 of the Councils largest, or most used buildings. The team is able to remotely identify and target improvements in the portfolio and be alerted when anomalous usage occurs. The system is now a core component of delivering to the corporate property portfolios emission reduction targets of 50% reduction by 2030 and net zero by 2050 from the Councils FY2018 baseline.
Outcome
The council have achieved energy savings of 11.73GWh (the amount ~1,035 households use each year), avoided 1,231 tonnes of CO2-e and are on track to save $1.5m per year in operating costs. Throughout Covid-19 the team was able to monitor key sites remotely, ensuring they were efficiently shutdown whilst still ensuring appropriate ventilation for their use.
Auckland Council has also invested in the use of View, providing up-to-date and digestible data on the business’s progress so far in sustainability.
Webstar
Challenge
The print industry is known for its tight margins. Webstar has utilised ISO as a framework to continuously measure, plan and improve for some time now. Energy, as one of manufacturings largest costs became a target for applying this process to ensure the business could measurable improve and sustain energy efficiency gains.
Solution
Webstar found ESP from the EECA website and soon identified the data-driven approach fitted well with their desired approach. ESP identified a range of quick wins and then looked to detailed monitoring of key plant to sustain those gains, and identify more.
Outcome
Results have beaten expectations, with 5.7% reduction within the first year and now cumulative savings of over $250,000 resulting. On top of this, production costs have reduced by an estimated $500,000.
ASB
Challenge
ASB has branches of various sizes located all around New Zealand. Traditional energy efficiency approaches werent working – the team just couldnt be everywhere at once. Despite a range of efficiency improvements being taken, energy use and costs kept rising.
Solution
Initial analysis identified significant opportunities for improvement – right from Dargaville in the North to Christchurch in the South. In 2012, as a market first, energy monitoring was installed at every ASB branch and Energy Management Plan implemented to target a 20% reduction initially.
Outcome
ASB’s early leadership in energy efficiency and carbon reduction has seen energy use across the entire portfolio decrease by a staggering 46%. ASB has utilised the data analytics of the ESP platform and the ESP engineering team to embed energy and sustainability into their every day business.
Bayleys – Harbour Grounds

The portfolio comprises 7 premium Auckland waterfront offices with 7,000 tenants occupying 88,000 sqm. With a change of ownership, Bayleys needed to rapidly get up to speed with the buildings performance and continue improving its value as required by the new overseas owners.
Solution
Bayleys access ESP’s suite of services including monitoring, continuous commissioning and audits to deliver a data driven energy management plan for the portfolio.
Outcome
Over the portfolio there has been an average improvement in energy efficiency of 32%, saving tenants over $3million in costs and avoiding 2,700 t CO2-e. Multiple buildings now have 4 star plus NABERSNZ ratings with further improvements underway.
University of Auckland
Challenge
Auckland University has a very large property footprint, with a large and dynamic population using the facilities for a wide range of uses. Managing the portfolio with a small team to deliver financial and decarbonisation results is a big challenge.
Solution
ESP was selected to monitor energy use across the entire portolio. Our software provides a consolidated view of all energy meter data with easy to navigation right from total portfolio down to the individual loads.
Outcome
As the team work through the massive change projects and daily challenges of managing such a diverse range of buildings, our software enables the team to quickly identify the results of the improvement, and maintenance work carried out every day – no matter how large or small.
Chorus
Challenge
Chorus operate telecommunication sites right across New Zealand and had a goal of reducing costs and improving visibility
Solution
In 2015, ESP installed electrical sub-metering at 7 of Chorus’s core sites followed by Type 2 Energy Audit. This resulted in better energy use visibility and energy efficiency recommendations. In 2016, following the success of the initial work, ESP extended the retail metering rollout which allowed data from each of the 93 sites to be ingested into ESP’s advance data analytics platform. ESP have since then provided peak demand analysis, power use effectiveness tracking, energy alerts, regular steering group meetings to enable the asset managers to have complete visibility of their assets.
Outcome
The continuous energy efficiency engagement has resulted in a 16% reduction in energy usage since the start of the programme. ESP continues to work with Chorus to optimise energy and related costs at their sites.
Vulcan Steel
Challenge
Vulcan steel had little visibility into energy usage at their site in Auckland. The site wanted assistance in sustained reductions in consumption and better data to make informed future investment decisions.
Solution
ESP installed sub-metering system followed by a Type 1 energy audit at the Auckland site identifying opportunities to improve machine utilisation, reduce compressed air usage, and upgrade lighting.
Outcome
This engagement has resulted in 25% savings in the first year alone. This was achieved with better shift management to double production levels from baseline year. The factory has also upgraded their lighting to LED. Vulcan Steel continues to engage ESP in tariff negotiation at other sites.
Wilson Hellaby
Challenge
Wilson Hellaby at their Auckland Site wanted to better understand their energy use in different areas of the plant. Additionally, they were keen to improve energy efficiency and reduce costs at their site.
Solution
ESP installed electrical submetering followed by ongoing consultancy services to engage with the site. ESP consultants regularly engage with site for after-hours review, steering group meetings, building business cases, and carry out detailed analysis of sub systems.
Outcome
In the last 4 years, the engagement has managed to achieve energy reductions of 11 million kWh equating to over $1 million. The site has not only reduced utility costs but also reduce maintenance costs.
Mobil Oil
Challenge
Mobil were looking for a way to reduce energy usage at 118 fuel stations across New Zealand. ESP benchmarked the sites according to type and provided a cost-effective solution for a monitoring and targeting programme.
Solution
A combination of retail and sub-load metering was installed at 20 fuel stations across the country. These sites were the most energy intensive. ESP carried out site reviews and set up frequent steering group meetings to review, track, and implement the actions that were recommended.
Outcome
The project has resulted in energy reduction of $440,000 since September 2017. ESP continue to monitor the sites as well as discuss new recommendations with Mobil to continue their energy efficiency journey.
Counties Manukau Super Clinic
Background
The Counties Manukau Superclinic is a modern dynamic building. Staff and patients need high levels of comfort and control over the internal environment. Unfortunately the building was performing poorly, with very high energy use per square meter.
Solution
An energy management plan laid out the solution which included detailed sub-metering on all utilities, along with the establishment of a continuous commissioning programme. Even small inefficiencies in an HVAC system can mean huge energy wastage over time.
“Because we use sub-metering to identify day-to-day fluctuations in our energy use, we can combine this with detailed interrogation of the BMS to pinpoint a problem when it pops up, fix it, and stop the energy wastage as it occurs.” Mark Davies, Energy Manager
Outcomes
The programme of monitoring and optimising the HVAC system at Counties Manukau SuperClinic saves hundreds of thousands of dollars in operational costs per year.
WineWorks
Challenge
WineWorks have set a goal of improving sustainability, however to improve operational performance and reduce scope 2 emissions the team need to gain timely visibility of electricity, LPG and water consumption at their Malborough plant.
Solution
ESP completed a Type 2 energy audit and installed targeted electricity metering supported by EECA funding. The analysis identified a range of efficiency opportunities including lighting, compresed air, nitrogen and after hours usage. Detailed monitoring identified how production usage and other factors impacted energy use, allowing accurate businesses cases to be developed.
Outcome
A clear plan of improvement was established to deliver initial savings. In the first 12 months lighting was replaced and a preventative maintenance plan to regularly check and fix air leaks was put in place. Monitoring has also provided the information needed to demonstrate to staff the benefits of improved shutdown procedures and the ability to continuously monitor impact. In the first year savings of 5% were achieved with a further 15% to 20% planned in the near future with upgrades to the nitrogen system and air compressors. The site is also looking forward to the new dashboard, with energy efficiency featuring more strongly in manager and team leader objectives…sustainability integrated into business performance!
