This amazing piece of 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 research house owned by CMHC and NRC was used to provide field
data for validating the software. A number of different furnace and chimney
setups were built and instrumented. This field 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!
SIMULATE A WOODBURNING FIREPLACE
This program is built on Fluesim, above. It can simulate the interaction
of a house and a woodburning fireplace or stove. You can see the effect
on house pressure, for example, when you switch from an open masonry fireplace
with an 8x12 flue to one with a 12x12 or larger flue. A unique program,
nothing else like it has ever been written.

SIMULATE A WHOLE HOUSE AND LOCAL
Written at UCLA, this sophisticated program allows you to model the energy
performance of a house and its interaction with the local climate. Designed
for architecture students, it is easy to use and comes with good documentation.
You can add varying amounts of windows or thermal mass, for example, and
see the result output as a stunning graphical "data landscape"
that shows you how these factors will influence indoor temperature and
energy consumption. An extremely valuable "what-if" tool for
anyone designing a house and wondering about passive solar and thermal
mass. Don't speculate - simulate!
CALCULATE A STANDARDIZED FUEL CRIB
The screenshot below is a fuel crib calculator developed
(Windows XP instructions:)
Copy the entire folder named "Masonry_Heater_Shapes" onto
your C: drive
Right click on your start button and "Explore"
Click on your C: drive and find the folder marked "Masonry Heater
and click on it.
Click on the Masonry3Installer folder and click on the "install"
The Masonry Heater program will be in your program list.
As part of the ASTM standards process, the masonry heater
subcommittee is proposing a standardized fueling protocol that can be
for emissions, efficiency and safety testing.
A first step is to qualitatively compare a firing using
the current draft fuel crib with a firing using a typical fuel load, for
sizes of heater.
The first tests were
done by Lopez Labs on a 22" Heatkit heater located near the Lopez
facility in Shawville, Quebec.
