Client engagements
Don’t just take our word for it.
Here are some real world examples of what retail property clients have achieved with our help. If they sound like the results you want, let’s talk.
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.
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.
CBRE
Challenge
CBRE have teams throughout the country, managing buildings on behalf of landlords. CBRE works to improve the value of the buildings managed however staying on top of large and distributed portfolios means the team need to be as productive as possible.
Solution
CBRE and ESP have worked closely for a number of years, continually auditing and monitoring an increasing range of buildings to ensure they are energy efficient. As landlords start to see the advantages a program of NABERSNZ ratings have started, meaning the CBRE portfolio can compete for high quality, including government, tenants.
Outcome
Having worked together for a while means the CBRE portfolio are achieving above average NABERSNZ results. The CBRE team are able to be more productive and can communicate the results to landlords, backed by proof, including the use of View, a set of live sustainability dashboards that provide instant and in-situ updates on the business’ sustainability journey so far.
NABERSNZ – Bayleys House
The list of sustainable credentials for Bayleys House continues to grow with not one but two NABERSNZ ratings.
Background
Managed by a partnership of Australasian asset managers; 151 Property, and Bayleys Property Services, optimising building performance and offering healthy, comfortable workspaces for tenants is top of the agenda.
NABERSNZ assessments were sought for a variety of buildings as a means to ensure consistent, accurate and verifiable results across a broad range of criteria and to enhance sustainability.
Solution
ESP engaged with the building management partnership, utilising cutting-edge technology and monitoring software to quickly and efficiently secure strong NABERSNZ ratings for the properties. The ratings were a mixed of tenancy and basebuild.
Results
A collaborative sustainable approach between landlord, property managers and tenants has delivered a high 4.5 star NABERSNZ base building rating for Bayleys House in Auckland waterfront’s dynamic commercial VXV Precinct.
Realty group Bayleys, who leases its head office in the building, has also earned a 4 star NABERSNZ rating for its tenancy – reflecting its strong commitment to the environment.
NABERSNZ assessor Hong Lee says high quality mechanical services including a fresh air system with a connected heat pump, have been instrumental in the achievement of a 4.5 star NABERSNZ rating for Bayleys House. The integrated heat pump provides consistent heat efficiency and reduces the need for electrical heating to kick in when the building cools down in winter.
Bayleys House has 70 energy monitoring meters spread across the building.“We can monitor down to 15 minute segments of energy use and you can even see the impact on air conditioning services if a staff member comes to work at 3am,” says Hong.
He says well-designed tenancy office services including LED lighting and occupancy sensors which switch off after 30 minutes, have driven the 4 star NABERSNZ tenancy score for Bayleys head office. A regime of normal daytime working hours has also propelled the Bayleys head office’s optimum energy performance.
Bayleys House also features the use of View, allowing stakeholders and staff to instantly understand how far they’ve come – and how far there is to go – on their journey towards meaningful sustainability.
University of Auckland

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.
Bank of New Zealand
ESP accurately diagnoses one of the biggest pain points in sustainability, reporting and provides a viable, innovative, solution.
Background
Bank of New Zealand (BNZ) is one of New Zealand’s largest banks. It employs over 5,000 people and operates a nationwide network of 180 retail stores and business centres. BNZ must report its carbon footprint, energy use and water consumption twice yearly to its parent company.
Challenges
BNZ’s carbon capture and reporting process was heavily reliant on spreadsheets. There was immense time pressure at reporting time with only 6 weeks to gather all data from suppliers; collate, analyse and comment on trends; and submit individual spreadsheets on 15 different types of data.
Each spreadsheet had to contain all source data, emission factors, commentary and approval, and ensure the correct version of the file was being passed around.
Reviewing and approving the data was extremely time-consuming, unreliable, open to human error and in some cases wasn’t possible at all.
Management and board didn’t have confidence in the accuracy and reliability of the emissions report and figures presented to them
Outcomes
The bank has now visibility of the entire emissions profile, all of the emission sources, all of the base data, all of the emissions factors, and carbon dioxide equivalents.
BNZ is now able to perform analytical and historical comparisons at any level of detail the bank wants, to review it.
Utilizing a smart approval process and automated notifications ensures activity data from internal and external suppliers is received, reviewed and approved on time.
ESP, formerly BraveGen, completely transformed the process and provides BNZ with the level of governance and oversight to feel confident that the data is absolutely right.
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.
IAG
