Energy assessment and equipment upgrades reduces energy use - Majors SUPA IGA


Australian Government



Central Victorian Greenhouse Alliance Incorporated (CVGA)


Major’s SUPA IGA has served its community for more than 100 years.  The owners have implemented numerous energy efficiency measures including airlocking the store entrance - creating a thermal barrier, by installing a second door, reduces air exchange between external and internal areas of the store, and cuts the heating, cooling and refrigeration load. Upgrading the heating and cooling system - installing variable speed drives to the heat pump and upgrading the cooling tower to a compressed condenser with high efficiency fans to reduce energy input to energy output requirements and increase energy performance of the whole system. Upgrading to light emitting diodes (LEDs). Powering down point of sale and other equipment when the store is closed reduces energy consumption. Adjusting thermostat settings to reduce heating, cooling and refrigeration loads.
