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.
Efficiency ratings established per test standard ANSI/ASHRAE 103-1993. ** Based on sound pressure levels during steady-state, high-fire operation of Lennox SL280UHV070V36A and leading competitive units at mid-point temperature rise and minimum external static pressure when set up per Section 4.5.3 of AHRI 260-2001.
