The Importance of Thermal Conductivity in Bio-Based Building Materials

Presented by Arya Hakimian

As the construction industry moves towards more sustainable alternatives, such as hempcrete pictured above, it’s important that the thermal conductivity of green building materials is accurately characterized to understand thermal performance.

Bio-based materials are those that are made from renewable biomass sources such as plants and forestry materials. Reduction of synthetic material usage from non-renewable resources or repurposing of otherwise to be disposed of waste can be of great value from a material cost and environmental standpoint. While these benefits can be significant, how do these bio-based materials compare performance wise? An area that has seen a lot of application of bio-based alternatives are building materials such as insulations, cements, and concretes. In these applications, thermal conductivity plays a critical role when evaluating performance and it is important to have a way to accurately quantify this.

It is important when measuring thermal conductivity to measure under representative conditions. In particular, humidity levels play an important role in concrete properties, yet depending on the method used to test thermal conductivity, this property can go uncontrolled. 

In this webinar we will discuss important considerations for thermal conductivity measurements on these material types including method selection and testing conditions. We will also highlight recent research published by C-Therm’s clients in the field across a range of bio-based materials.

This webinar is recommended for any green materials scientists or engineers working with or interested in novel bio-based building materials.
