| Outline of Final Research Achievements |
Firstly, this study tried a detailed evaluation about the effect of energy conservation retrofitting for a grocery store upon energy consumption and consumers’ purchase behavior. Concerning the energy consumption, the retrofitting could reduce 45% a year. In addition, consumers had an affirmative impression for the retrofitting that would give a bad influence to consumers.
Secondly, we focused on the cold refrigerating showcase (refrigeration equipment), we attempted to quantitative evaluation of energy conservation measures related to the cold refrigerating showcase. Consequently, by adopting closed reach-in type showcase instead of open multi-stage type as a cold leakage countermeasure, energy consumption of refrigerating machine was reduced 69% in July average. For the annual savings of the entire store considering the air conditioning load was 27%, while the consumption of the air conditioner was greatly increased, since the refrigerating machine and defrosting heater was reduced.
