Abstract: An electric power demand adjustment program management apparatus, comprises a server which includes: a communication unit that communicates with a plurality of customer terminals that manage customer devices through a communication network; a program unit that creates an electric power demand adjustment program showing a demand adjustment amount allocated to at least one first customer terminal selected from the plurality of customer terminals in each predetermined time segment, based on predetermined constraint conditions and predetermined information received from the plurality of customer terminals; a program executing unit that transmits the electric power demand adjustment program, and instructs the first customer terminal to execute the electric power demand adjustment program; and a providing unit that provides, when the program unit fails to create the electric power demand adjustment program, investigation result information including an investigation result for a cause of the failure.

Abstract: A showcase includes a main body a front face of which is covered by a door (6) having a glass plate (5), so that the front face is opened and closed by the door (6), in which a rod-shaped illumination module (16) is disposed in each of grooves (14) of left and right supporting column frames (12) that define an opening on the front face of the main body that is opened and closed by the door (6). Each of the illumination modules (16) has LED lamps each constituted by an LED and a lens, and arranged at regular intervals and integrated together. Thus, commodities (7) arranged along the front end of each shelf (8) are illuminated with direct light from the illumination modules (16) and reflected light from the glass plate (5). By this configuration, it is possible to reduce variation of illuminance among commodities and shading and shadows between the commodities arranged along the front end of each shelf.
