Abstract: In this project, we aim to identify a small set of newly constructed buildings with mass timber floors and/or walls, and test their acoustical performance following ASTM field testing protocols, while also collecting subject feedback from building occupants. We will add frequency resolved acoustical testing data to a public repository that will include both new field tests and previously collected laboratory testing data for comparisons to be made where applicable.

Abstract: In order to address the need for more acoustic data on mass timber assemblies, TDI awarded funding, including part of an EDA grant, to the ESBL in 2018 to conduct acoustic field testing on existing mass timber buildings and ASTM-certified laboratory testing of both dry and wet (concrete-composite) assemblies using CLT and MPP.

Abstract: This project aims to solve one of the biggest barriers to increased market adoption of mass-timber buildings - energy consumption. The project team will explore how to replace the concrete typically needed for night flush cooling of thermal mass. The goal is to provide results that will help mass-timber buildings achieve net-zero energy priorities for a larger range of use types and climate zones while also providing new insight into human perception of thermal comfort in mass-timber buildings.

Abstract: New research is showing that wood buildings are more likely to harbor environmental microbes with beneficial health effects. This pilot project will study various surface materials in both the lab setting and occupied mass timber buildings to assess effects on occupants’ health and comfort as well as indoor air quality.
