Standard
Temperature and Pressure[LINK]
Several objects specify inputs at “standard temperature and
pressure”. Standard Temperature is dry air at 20oC
drybulb. The program uses local barometric pressure to account
for altitude using the equation for “standard atmospheric”
pressure on p 6.1 of the ASHRAE 1997 HOF (SI edition) to
initialize the air systems being simulated.
\[Stdpressure = 101325{\left(
{1.0 - Z{{2.25577}^{ - 5}}} \right)^{5.2559}}\]
where
\(StdPressure\) = pressure
{Pa}
\(Z\) = altitude/elevation
{m}
