Acoustic Field Testing of Mass Timber Buildings

2019 - 2020
Project Lead: Kevin Van Den Wymelemburg
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.

Net-Zero Energy TallWood Design

2017 - 2019

Project Lead: Kevin Van Den Wymelenberg

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.

Acoustic Lab Testing of Typical Multi-Family Residential CLT and MPP Dry and Concrete-Composite Wall and Floor Assemblies

2018 - 2020
Project Team: Kevin Van Den Wymelenburg (PI), Mark Fretz, Dale Northcutt
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.
