It can reasonably be expected that this additional heat will not be constant. Working people cannot sit at home all day using their PCs. The environmental space designs for ships are not nearly as tolerant. Planning for equipment installations to include plumbing or extra ventilation that does not increase the heat loading in a compartment is generally required. Vibration Vibration in the American household is almost always limited to small brief transients - passing trucks, sonic booms or the kid next door, with two major exceptions.
Earthquakes cause excessive vibration, but their effects are very brief and almost transient.
The second exception is achieved by coupling an aurally challenged teenager with today's audio extravaganza. Households with large, sophisticated audio systems that are operated more than intermittently at moderate to high levels of volume, can host a low frequency vibration hazard which could damage electronic equipment, especially computers. But, for the most part, vibration in the household does not affect computer equipment. Vibration on ships is not quite the same. Equally destructive, over a longer term, are the frequent, higher frequency transients that are normal to life on a metal vessel, such as hatches being closed, weapon elevators starting and stopping, heavy traffic on ladders and aircraft catapults.
