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. ESP Hub 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, ESP Hub enables the team to quickly identify the results of the improvement, and maintenance work carried out every day – no matter how large or small. 

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 70 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. Initial targets were low, however with the solution proving itself annual reductions of 5% are now targeted.

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 whislt still ensuring appropriate ventilation for their use.

Challenge

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

Outcome

The programme of monitoring and optimising the HVAC system at Counties Manukau SuperClinic saves hundreds of thousands of dollars in operational costs per year.
