Over 15% energy savings for landmark CBD building

Angas Securities House, 26 Flinders St, Adelaide



EfficientSee was involved in the first South Australian Building Upgrade Finance (BUF) project for 26 Flinders Street (a 16-storey commercial building in the CBD of Adelaide).

A detailed Level 2 energy audit was undertaken by experienced auditors and engineers at EfficientSee® who also prepared specifications and gathered quotes from contractors to feed directly into the financial feasibility analysis.

It resulted in several key projects including Power Factor Correction, Lighting upgrades and a Solar installation elevating the building’s NABERS star rating. It resulted in energy savings of over 15%.
