Join Illinois Green and Woodworks for a workshop diving into Mass Timber Construction & Mid-Rise Design on September 25 - Day 2 of the Drawdown Illinois Summit! 

Workshop attendees will participate in a two-part workshop exploring the technical details and best practices of building with wood through mass timber construction products and performance as well as mid-rise design opportunities. Earn 3.0 AIA LU/HSW and self-reported LEED continuing education credits.

Part 1: Mass Timber Construction - Products, Performance and Design

Due to their high strength, dimensional stability and positive environmental performance, mass timber building products are quickly becoming materials of choice for sustainably-minded designers. This presentation will provide a detailed look at the variety of mass timber products available, including glue-laminated timber (glulam), cross laminated timber (CLT), nail laminated timber (NLT), heavy timber decking, and other engineered and composite systems. Applications for the use of these products under modern building codes will be discussed, and examples of their use in U.S. projects reviewed. Mass timber’s ability to act as both structure and exposed finish will also be highlighted, as will its performance as part of an assembly, considering design objectives related to structural performance, fire resistance, acoustics, and energy efficiency. Other topics will include detailing and construction best practices, lessons learned from completed projects and trends for the increased use of mass timber products in the future.

Learning Objectives:

  1. Identify mass timber products available in North America and consider how they can be used under current building codes and standards.
  2. Review completed mass timber projects that demonstrate a range of applications and system configurations.
  3. Discuss benefits of using mass timber products, including structural versatility, prefabrication, lighter carbon footprint, and reduced labor costs.
  4. Highlight possibilities for the expanded use and application of mass timber in larger and taller buildings.

Part 2: Mid-Rise Design - Opportunity and Implementation

As increases in urban density become necessary to address growing populations, many building designers and developers are leveraging wood’s ability to achieve multiple, simultaneous objectives. Wood is a code-compliant solution to the challenge of how to cost-effectively increase density while creating vibrant and sustainable communities. Yet many familiar with the design of two- to four-story wood structures are not aware that the International Building Code allows five stories and more of wood-frame construction for residential uses such as student, senior and affordable housing, and for business, mercantile and military occupancies. Through an overview of design, detailing, and construction considerations, this presentation is intended to give architects and engineers the confidence to break into this growing market segment. Heights and areas will be discussed, including allowable increases, as will fire-resistive design, detailing for performance, shrinkage, structural framing, acoustics, and fire-rated assemblies.

  1. In the context of a shift toward greater urban density, discuss how mid-rise, wood-frame construction meets housing needs while creating vibrant sustainable communities.
  2. Discuss allowable construction types, occupancies, and building heights/stories/areas for wood-frame mid-rise buildings per the current International Building Code.
  3. Identify fire resistance and protection requirements for wood-frame wall assemblies in Type III and Type V buildings.
  4. Examine detailing best practices to achieve performance requirements for acoustics, lateral bracing, shrinkage effects, and floor-to-wall interfaces.
