Annex 31: advanced modelling and tools for analysis of energy use in supermarket systems.

Author(s) : ARIAS J., LUNDQVIST P., SAWALHA S., et al.

Summary

Supermarkets are the most energy intensive buildings in the commercial sector. It has been estimated that 3-5% of the total use of electricity stems from supermarkets in industrialized countries. In addition, it is estimated that the annual refrigerant losses are as high as 15-30% of the total charge thus making supermarkets the second largest emission source after mobile air conditioning. The supermarket sector has therefore a significant role to play not only from the point of view of the energy consumed but also from the point of view of the impact of refrigerant leakage. The main goal of Annex 31 is to provide new knowledge, methods and reasonable accurate simulation tools to assist in the analysis of the energy performance and in the development of energy efficient strategies for supermarkets. This has the aims of reducing global energy consumption, environmental impact and life cycle costs of a supermarket within constraints such as the required quality of products and maximized comfort of the occupants. Annex 31 is an IEA Heat Pump Program project.
