As with almost all of these programs to date, this program does not allow for the impact of local air leaks on both surface temperature and condensation along the leaks. In many troubled houses the program would not predict the presence of mold at or near leaks, but they would still be there.

Some programs in development will look at these effects, but the simultaneous movement of water and energy with moving air, in parallel with diffusion and wicking, makes modeling along complex paths very difficult indeed.

Good points !

As with all programs trying to simulate real world situations

they are far from perfect.

I did not imply that you could stay at your office to decide that

there is mold growing in a specific house / construction.  

(that would be really boring wouldn`t you say… :-)

But as a tool it can give you some ideas of where to look.   

Of course you would have to back it up by experience, a visual building

inspection, moisture measurements/logging, maybe opening of the construction

and sampling for mold etc….

Buildings

WUFI is a great program that has helped even a simple mycologist to better

explore/explain the potential for or occurance of mold growth in different

parts of a building construction during a year.

Gives a good visual presentation in a mold reeport also !

It is worth while a look !

By the way.... Would be interesting to run some of our 'simulations' based on

the climate in Norway on data from Florida.... Just to see how bad it can get

:-)

WUFI Pro and WUFI Plus in Miami Beach in September Greetings!

We are offering back-to-back WUFI workshops: WUFI Pro, the standard or

introductory workshop for modeling walls and roofs; and WUFI Plus, the whole

building modeling software. You can sign up for either workshop or both. WUFI

Pro is the prerequisite for WUFI Plus, as you need to learn how the basic

software works before you have the more complex inputs for modeling an entire

building.

WUFI Pro will be Thursday through Friday, September 25-26.

WUFI Plus will be Tuesday through Thursday, September 30 - October 1.

Both workshops will be at the Sheraton Four Points, Miami Beach, where they are

in the process of setting up a discounted block of sleeping rooms. Registrants

will be notified when the room block is set up.

ASTM is meeting just down the street at the Fontainebleau Hotel, so you may be

able to attend those meetings and a workshop in one trip.

About WUFI ®

WUFI series software allows the realistic simulation of the transient

WUFI Plus, Sept. 30 - Oct. 1

The hygrothermal behaviour of a building component that is exposed to weather

is an important aspect of the overall performance of a building. Today the

hygric transport phenomena through a building envelope are well understood and

a realistic assessment of all relevant effects can be carried out by one of the

numerous models and computer programs that have been developed in different

countries over the last years.

The calculation of the hygrothermal performance of a part of the envelope is

state-of-the-art, but until now the total behaviour of the actual whole

building is not accounted for. Its importance is increasing as modern dwellings

become more airtight and show elevated indoor humidity levels.

In this workshop new holistic models, that take into account the main

hygrothermal effects like moisture sources and sinks inside a room, moisture

input from the envelope due to capillary action, diffusion and vapour

ab-/desorption as a response to the exterior and interior climate conditions,

heat source and sinks inside the room, heat input from the envelope, the solar

energy input through walls and windows and hygrothermal sources and sinks due

to natural or mechanical ventilation will be presented. Beside the theoretical

background several practical applications will be shown.
