MacroFlo is a program for analysing infiltration and natural ventilation in buildings. It uses a zonal airflow model to calculate bulk air movement in and through the building, driven by wind and buoyancy induced pressures. Details of the methods used in MacroFlo may be found in the MacroFlo Calculation Methods manual. MacroFlo is invoked as an adjunct to Apache Simulation, as described in the Apache User Guide.
The preparation of MacroFlo input data in the MacroFlo view consists of setting the air flow characteristics of openings in the building (windows, doors and holes). Once these MacroFlo types have been assigned to openings, they can be included in the simulation.
A full user guide on MacroFlo is available from the Help -> User Guides.
