The Good Guys was founded by the Muir Family in Melbourne’s northern suburbs in 1952 and is one of Australia’s largest electrical appliance retailers, currently operating 103 stores across metropolitan and regional Australia and online. The Good Guys has won multiple customer service and retail honours; most recently winning the coveted Canstar Blue Most Satisfied Customers Award for a sixth year in a row.
The Good Guys management team approached SEDAC Energy Management (SEM) to provide a turnkey solution to reduce the electricity consumption at The Good Guys site in Wagga Wagga, New South Wales.
The Wagga Wagga site is the second highest consumer of energy within The Good Guys portfolio resulting in a large financial impact to the business. “This site is one of our worst performing in regards to energy and we need a solution now” stated Peter Dowling, CFO for The Good Guys.
SEM immediately actioned the request and completed the design and engineering of a bespoke BEMS for The Good Guys, Wagga Wagga store. The project target was to lower electricity use at The Good Guys, Wagga Wagga site by approximately 17% and to change the culture of the store’s staff around energy use and behaviour.
SEM’s methodology and approach was simple, deliver the site with efficient control of existing assets and provide visibility into ongoing energy consumption. This control and visibility ensures real time metering, monitoring and management of total energy usage, guaranteeing energy wastage is eliminated.
This well established and proven SEM approach and the subsequent installation and commissioning of the Building Energy Management System at The Good Guys, Wagga Wagga was very successful.The BEMS installation enabled the SEDAC Energy Management team to identify and analyse the sites energy wastage and decide how best to deal with it.
The BEMS optimised the operation of the HVAC and lighting systems, which reduced operational inefficiencies and mitigated various maintenance concerns. The energy savings achieved at The Good Guys, Wagga Wagga have reduced the site’s electricity consumption by 35%, resulting in electricity savings of $22,000 per annum. Additionally, The Good Guys, Wagga Wagga staff are now much more energy mindful and aware of the importance of certain processes that maintain reduced energy use at the site.
After implementing the Building Energy Management System, The Good Guys, Wagga Wagga management team not only observed a significant reduction in their energy bills but also noted the added Health and Safety benefits in terms of improved employee comfort levels. All these benefits contribute to the larger picture of a sustainable and reduced carbon footprint operation for The Good Guys, Wagga Wagga.
In today’s unstable energy market, measuring, monitoring, and controlling energy usage is more important than ever.
After the successful BEMS installation and commissioning of The Good Guys, Wagga Wagga site in November 2013, the site has preserved a 35% reduced level of energy consumption, year on year to date.
SEDAC Energy Management’s continuous review process, supported by our energy dashboard, tailored to our customer’s needs, enables SEM to see the true performance of site’s continuing operation. Various ongoing concerns such as equipment short cycling, chiller starts and loading, staging of HVAC equipment and faulty economisers all become transparent, visible, and controllable, ensuring the sites operating envelope and energy effectiveness is preserved.
Building Energy Management System (BEMS)
A bespoke cost effective BEMS utilising only high quality and reliable Resource Data Manager (RDM) equipment was designed and installed to eliminate operational and technical inefficiencies whilst optimising building performance. The BEMS provided visibility into the site’s energy consumption and additionally, provided sophisticated control of the site’s assets. Visibility into the energy consumption and asset performance ensured any specific building operational problems were detected early before they cost valuable money in repairs and downtime.
Automated lighting control was installed for internal and external lighting which included zoning areas based around time schedules, staff occupancy and daylight sensing. The SEDAC Energy Management BEMS has removed all operational inefficiencies and ensured that all lighting areas are controlled efficiently. This system will not only increase the lifespan of lighting but also allow staff to concentrate on sales rather than routine operations.
The SEDAC Energy Management BEMS has ensured that the site’s air conditioning units are efficiently controlled, at the same time as Improving and maintaining occupant and customer comfort levels. The BEMS will also assist with preventative maintenance through smarter control strategies which will prolong the lifespan of equipment. The customised logic and control of the system creates internal, external economy cycles and floating set points amongst others. Heating demand is decreased during cooler periods by recycling the heat inserted into the building from the high-powered lighting. During warmer periods the economy cycles are controlled more efficiently to reduce the cooling demand.
Incorporated within the BEMS cubicles are robust sub metering equipment. The metering, combined with the BEMS interface, enables SEM to produce a web based energy monitoring application that provides real time access to current and historical energy usage data for energy monitoring and analysis anytime, anywhere via the Internet using a web browser.
The SEM web portal automatically collects and manages valuable energy data and then translates the data into useful and actionable insights for SRG end users. The cloud-based data capture and analysis assists control over energy costs via a variety of interactive and automated energy analytics tools that are delivered via a convenient
and easy to use web browser.
Additionally, it presents current data up to the last granular interval, hourly, daily, and monthly or yearly as well as historical data both in tabular and graphical form providing greater visibility and control of energy consumption. This visibility assisted to uncover hidden saving opportunities in varying complex energy environments.
