A Study on the Energy Certified and Consuming of the Supermarkets in Taiwan

Abstract

The European Union issued the "EPBD (Energy Performance of Building Directive)” in 2009, as a building energy consumption labeling standards. Taiwan's government to conform to the international trends, try to establish building energy certification especially for the retail store. The growth in the supermarket of Taiwan is very rapid, the number of the country more than 800. Because the area in the supermarket is large, illuminate, air conditioning and a large number of refrigeration equipment, therefore the supermarket is the high energy consumption type. The average annual power density “EUI (Energy Use Intensity)” is 677 [kWh/(m2.yr)], the average annual consumption of electricity is up to 1,024,276 [kWh/yr] above. Due to the indoor area and different types of supermarket, we can’t define a single EUI standard, this study through the "building dynamic partitioning EUI index " method, classify the space functions of supermarket six kinds of different energy densities, for: A zone (arcade district), B zone (warehouse and other space such as corridors, counters, stairwells, elevators, toilets, etc.), C zone (refrigerated and frozen zone such as freezers area and equipment space), D area (food processing area such as kitchen), E area (office), F zone (general goods area). When evaluating the future of the supermarket energy consume, as long as calculation the district area and EUI through the weighting calculate, we can immediately get a supermarket energy consumption standard, not only can be used to diagnose energy rationality of existing supermarkets, but also help the new supermarket energy forecast in the future.
