Breaking Barriers in Sustainable Building with WUFI!

The Canadian building code isn't exactly welcoming to change—especially when it comes to alternative, low-carbon materials like hempcrete. The path to approval is complex, and without the right data to provide to professionals asked to consider these materials, the materials struggle to gain traction. Luckily, that is starting to change. And, that’s where WUFI Plus comes in.

By funding this purchase, you're helping me bring cutting-edge moisture and energy modeling to alternative construction, providing the critical data needed to prove performance, refine applications, and push for real change in building codes. With your support, I can bridge the gap between innovation and regulation, ensuring that sustainable materials get the validation they deserve. Let’s make vapor-open, high-performance building materials the future of Canadian construction!

How exactly would WUFI help?

Provide a comparison performance analysis of assembly elements or whole building systems.
WUFI accommodates vapour-open moisture variable materials, so we can capture actual performance of these materials in assemblies.
WUFI combined with my long experience in the moisture physics and real-world application (including testing and research), can provide realistic comparisons.
Provide analysis for funding applications to catalyze approval and applications.
Provide groundwork and a body of research/documentation to building professionals and clients across Canada for northern construction applications.

WUFI is a German software that has been in use for over 25 years. It is complex and comprehensive if you understand the physics and materials science embedded within. Because we can bring our experience and understanding of materials to WUFI, we are able to use it effectively as a major tool to address barriers to adoption of alternative materials.

It is also expensive.

So we are asking for your support in exchange for a WUFI analysis, or other benefit, like one of our design packages (we just released a FREE backyard greenhouse design , no obligation, to help anyone with food security and introduce them to growing and hempcrete).

If you are interested in a WUFI analysis, please consider donating to help us get access to the WUFI Plus software (details below).

Thank you!

Note that any extra funds raised will be used towards training and learning.

ALL FUNDS will go to WUFI software (perhaps getting the 5 year license, even)

WUFI Plus capabilities and details:

https://wufi.de/en/software/wufi-plus/

WUFI® Plus is the most complete heat and moisture simulation tool in the WUFI® software family. In addition to simulating hygrothermal conditions in building components, WUFI® Plus simulates the indoor environment and is therefore suitable for addressing comfort and energy consumption in buildings. Since simulations are based on user-specified climate and on user-defined ventilation, HVAC, and internal loads, the simulations can accurately represent the situation at hand.

Simulation of the interaction between building usage and system technology allows for integral assessment of indoor climate, hygienic conditions, thermal comfort, indoor air quality, and damage to components as a function of heating and cooling loads and the necessary effort to humidify/dehumidify.

Integrated modules for dynamic analysis of 3-D bodies (e.g., thermal bridges) and for air exchange between conditioned zones and the outside further expand the capabilities of WUFI® Plus.

Besides the dynamic hygrothermal building simulation WUFI Plus can also be used for Passive House design and certification and to verify the summer heat insulation according to German DIN 4108-2 Standard.
