Case Study: ASB cuts energy use by 49% with BraveGen’s monitoring and analytics

ASB cuts energy use by 49% with BraveGen

ASB Bank, a major New Zealand retail bank, faced the challenge of meeting its ambitious energy reduction goals with limited insight from traditional monthly billing data and energy audits. This lack of real-time visibility prevented the property team from identifying inefficiencies and prioritizing upgrades across its 100+ sites. To overcome this, ASB partnered with vendor BraveGen for its comprehensive monitoring and analytics services.

BraveGen implemented a solution featuring portfolio-wide real-time energy monitoring and automated data integration from sub-meters at every site. This provided the visibility needed to launch a targeted performance improvement program. The results were significant: ASB achieved a 49% reduction in energy use, saving $2.1 million NZD annually and avoiding 11,575 tonnes of CO₂‑e. The BraveGen platform also streamlined carbon reporting and helped ASB earn a 5 Star NABERSNZ rating for its headquarters.
