Build chimneys on your desktop - Fluesim

This amazing software was developed by the Research Division of Canada Mortgage and Housing Corporation in the 1980's. It simulates a whole house system, including envelope, chimneys, furnaces, exhaust appliances, etc. It can simulate a wide variety of conditions, and was developed originally to gain a better theoretical understanding on indoor air quality problems related to such things as carbon monoxide spillage during the startup phase of oil and gas furnaces.

A full scale research house was built by CMHC and NRC and used to generate field data for validating the software. A number of different furnace and chimney setups were built and instrumented. This data was then used to calibrate and fine tune Fluesim. The program was later extended to include woodburning fireplaces and stoves and called Woodsim. To use it, download the file Fluesim.zip. Unzip the files into a new directory, and read the readme.txt file for instructions. The program runs in DOS. Have fun!
