Improving Thermal Efficiency in Lightweight Construction: mass timber as thermal mass

Improving Thermal Efficiency in Lightweight Construction: mass timber as thermal mass

The research aimed  to obtain new data to inform opportunities to further improve the thermal efficiency of light-weight, timber framed, small to medium scaled buildings. The principle task of this project was to complete an empirical study assessing the measured thermal performance of mass-timber. 

This empirical study, within real buildings, could then be used to corroborate previous published building heating and cooling energy simulations, which had shown significant thermal performance benefit when mass-timber was substituted with standard framed systems, and concrete and clay brick thermal mass systems. 

In the evolving world of increased building regulation and an increasing market expectation for low energy homes there is a need to clearly and simply show how the renewable Australian timber resource can be used to provide thermally comfortable housing, whether they be located in the hot and humid climates of the North or the cooler Southern temperate climates.

This report, Improving Thermal Efficiency in Lightweight Construction: mass timber as thermal mass, is derived from the recently published FWPA funded project (PNA289-1213). g

FWPA Newsletters

FWPA regularly distributes industry updates and information through e-newsletters including ForWood, R&DWorks, Statistics Count and The Ultimate RenewableTM Partner Update. ForestLearning, our education program for teachers, educators and school children, also publishes a quarterly e-newsletter and ensures school communities and the public are informed on Australian forests and forest-based products.

Additionally, WoodSolutions publishes a newsletter that addresses design and build professionals – architects, building designers, engineers and others involved in specifying the choice of building materials.
