Project Objective

This project will make available to the designer community key material properties of bio-based materials that would be used in building envelope applications. A bio-based material is a material comprising substance(s) derived from living matter (biomass). Bio-based materials can be substituted for some products traditionally used in the buildings sector. The development of this database will allow designers to evaluate the impact of these material substitutions from an energy efficiency, comfort, and durability perspective.

The project will produce a database of hygrothermal and transport properties on bio-based building materials that can be readily added to and used by energy and durability simulation tools. The database will also be made available to reference databases.

Project Impact

This project seeks to address how quickly the design community develops confidence in utilizing these new bio-based products. The availability of quality data developed using consensus methods by a trusted source that can be used by simulation tools to evaluate the energy, comfort, and durability of these new materials that are deployed in opaque building envelope components will eliminate the barrier of being able to use existing design tools to evaluate these materials. By allowing designers to evaluate the energy efficiency and comfort impacts of using bio-based envelope materials, this database will accelerate the adoption of these materials across the energy sector.
