The directors of the Spotlight Retail Group have homewares in their blood. Three Generations have spent their working lives around haberdashery and homewares, leaving the current custodians of the business, Zac Fried and Morry Fraid, with a proud tradition they want to protect. The Spotlight Retail Group, is a family owned and operated Australian business with stores throughout Australia, New Zealand and Asia. SRG employs more than 6,700 team members who are dedicated to providing the best quality, service, price and expertise in fabrics, craft and homewares to millions of customers each year.
When Grant Wheaton, Spotlight Retail Group General Manager, Property and Store Development, made the decision to advance SRG’s energy efficiency efforts, he contacted SEDAC Energy Management (SEM) to provide a turnkey solution to reduce the electricity consumption across the Spotlight Retail Group portfolio and mitigate against rising energy prices. Grant knew he was on the right energy efficiency path with SEDAC Energy Management, having successfully implemented a similar SEM Building Energy Management System (BEMS) strategy at another large format retailer. Grant presented the BEMS concept to the SRG directors knowing the fundamental value the BEMS solution had to offer.
Spotlight Frankston, which is owned by the Spotlight Property Group, was chosen as the initial trial site. The store was a high-energy consumer within The Spotlight Group portfolio, resulting in a large financial burden to the business. “This site is one of our poorest performing in regards to energy consumption and we need to improve this now” stated Grant.
SEM immediately actioned the request and completed the design of a proprietary BEMS for the Spotlight Frankston store. The project target was to lower electricity use at the site by 15% and to change the culture within the store’s staff around energy use and behaviour.
SEM’s methodology 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, assuring energy wastage is eliminated.
The ensuing installation and commissioning of the Building Energy Management System at Spotlight Frankston was extremely successful. The BEMS optimised the operation of the HVAC and lighting systems, which reduced operational inefficiencies and mitigated various maintenance issues. The site’s electricity consumption was reduced by a staggering 46.8% or $57,284 per annum. Additionally, the store’s staff are now much more energy conscious and aware of the importance of certain processes that maintain reduced energy use at the site. The overall BEMS installation and subsequent energy reduction exceeded all expectations.
Following the impressive trial results at Spotlight Frankston, Grant Wheaton approved a further 12 sites, comprising of both Spotlight and Anaconda stores, for a BEMS Installation. Independent measurement and verification of the energy reductions under International Performance Measurement and Verification Protocols (IPMVP) corroborated and recognised significant energy savings across the 12 sites which formed Stage 1 of the BEMS rollout, totaling $239,328.
This was an average energy saving of 21.1% or $19,944 respectively with a tremendously attractive return on investment or payback of 0.83 years.
To date, SEDAC Energy Management have completed over 65 positive BEMS installations across both Spotlight and Anaconda stores with another 35+ earmarked in 2017.
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.
