Mechanical room (see: mechanical floor). Mechanical rooms typically house the following equipment: Equipment in mechanical rooms is often operated and maintained by a stationary engineer or a maintenance technician. Modern buildings use control systems to manage HVAC cycles, lighting, communications, and life safety equipment. Often, the control system hardware is located in the mechanical room and monitored or accessed remotely. Rooms with only electrical or electronic equipment are not considered mechanical rooms but are instead called electrical rooms. Mechanical room A mechanical room or a boiler room is a room or space in a building dedicated to the mechanical equipment and its
Mechanical computer terrestrial globe, plus latitude and longitude indicators. Mechanical computers continued to be used into the 1960s, but were quickly replaced by electronic calculators, which—with cathode-ray tube output—emerged in the mid-1960s. The evolution culminated in the 1970s with the introduction of inexpensive handheld electronic calculators. Mechanical computers were ailing in the 1970s and dead by the 1980s. In 2016, NASA announced that its Automaton Rover for Extreme Environments program would use a mechanical computer to operate in the harsh environmental conditions found on Venus. Early electrically powered computers constructed from switches and relay logic rather than vacuum tubes (thermionic valves) or
