Types of Fire Pumps. A fire pump is a specialized water pump that provides constant, high pressure for a water system used to extinguish fires. The fire pump intake can be connected to an underground water pipe or a static source, such as a water tank or reservoir. Fire pumps may be powered by an electric or diesel motor.
ASHRAE 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings) is a US standard that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings. The original standard, ASHRAE 90, was published in 1975.
Nor does the Joint Commission state what the air exchange rates should be, but would expect that you follow your state licensing requirements or an industry standard, such as the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE), which has many recommendations for air exchange rates.
