Supermarket Energy Retrofit
Supermarkets use nationally significant quantities of energy with an average store exceeding 600 kWh/m2 pa. The reason is simple. The design of these stores is to maximise sales and minimise initial costs. Energy costs are insignificant compared to the huge turnover generated, often less than 0.4%. If any energy conservation measure (ECM) has even a slight negative impact on sales, the savings for the storeowner will be wiped out. Can an existing supermarket be retrofitted to substantially reduce energy consumption and maintain or increase sales? This is the challenge that confronted us with our first supermarket energy retrofit and yes it can be done. We have achieved 36% energy savings and total sales for the store have increased 6% over the same period.
