APA’s South Australian branch at Kidman Park were keen to know how they could deliver more energy efficient internal operations, and so engaged the services of Tandem Energy to provide a level 2 Energy Audit in mid-2017.
The facility plays host to both a workshop, for repairing and maintaining the pipe-lines, and a two-level office building in which the monitoring of assets takes place.
APA E&I Engineer, Peter Pirgousis explains, “One of our key objectives in undertaking an energy audit was to understand how were using our energy so that we make educated decisions for future investment.”
The focus of the business has shifted towards monitoring, with the majority of energy being consumed by the office building. While lighting and IT consume a large portion of the total energy consumption, mechanical services, (heating, cooling and ventilation (HVAC)), is the biggest consumer. With numerous HVAC units located across the site, good control over this area is vital, and was the main focus of the energy audit undertaken by Tandem.
The old adage, “you can’t manage what you can’t measure” is most certainly the case when it comes to energy auditing, and one of the best tools to measure energy use is a data logger. Though not stipulated as part of a type 2 energy audit, data logging gives the clearest picture as to what is really going on behind those walls (and ceilings). In total, 7 data loggers were installed across the workshop and office area, with notable results.
