Hotels, motels, and dormitories may be single-room or multiroom, long- or short-term dwelling (or residence) units; they may be stacked sideways and/or vertically. Information in the first three sections of the chapter applies generally; the last three sections are devoted to the individual types of facilities. High energy costs and consequent environmental damage require that these type of facilities be energy efficient and sustainable. Occupants need assurance that they can afford the fuel bills and that their lifestyle is not damaging to the planet. This chapter provides advice on sustainable practices to achieve these aims.
