How A Building's Design Can Waste Energy

Room Not Using Electricity Efficiently None of the outside rooms in this building take advantage of natural light. Although the building is configured with a large number of rooms on outside walls, each of the rooms is sealed. This is indicative of the period in which the building was constructed, but consumes a large amount of electricity for no practical reason given current construction options.
