AIDA - an air infiltration development algorithm.

AIDA is a basic infiltration calculation procedure intended for the calculation of air change rates in single zone enclosures. It also determines flow rates for up to 10 user defined openings and calculates wind and stack pressures. This program is very easy to use but, nevertheless, provides an accurate solution to the air infiltration flow balance equation. As its name suggests this is a development algorithm which may be readily adapted to include additional flow paths, mechanical ventilation and many other features. In less than 60 lines of computer code, AIDA is capable of solving almost any single zone problem on almost any level of computer.
