Tests

Blower door test

  • Change wall_ext, wall_int, wall_inter-apt, floor, and roof to 10 cm2/m2

  • Close all openings

  • Run blower door test at PA = 4

  • Copy into spreadsheet and change calculated surface area to match that of current building

  • You should get back 9.999 cm2/m2

  • If not, likely errors are:

  • The wall area or height isn’t correct for wall_ext

  • Gable is open, window is open, door is open

  • Missing a floor or roof leak

  • One element isn’t 10 cm2/m2

Steady state airflow

  • Provides a general view of interzone airflows including SAHS supply and return

  • Stack effect test:

  • Set ambient to 0 degC (indoor = 20 C)

  • Turn all AHS schedules to Off

  • Run SS simulation and check envelope flows exhibit stack flow pattern

  • Should be no flows through closed windows or doors

Transient

  • Run at least 2 weeks

  • Allows the use of RESTART file in coupled simulations

  • Runs a building check to test definition of PRJ

  • Provides other checks

Reset prior to running

  • Transient

  • Contaminants to transient

  • Reset flow elements to correct leakage

  • Adjust the start and end dates

  • Turn ahs back on

  • Adjust the output and calculation timesteps (every 5 min)

  • Use the RESTART file
