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.
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.
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.
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!
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.
Bayleys – Harbour Grounds
Challenge
The team at Bayleys manage the large property portfolio in Wynyard Quarter now named 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.
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.
