Learning Objectives
At the conclusion of this session, participants will be able to:

• Review the history of mass timber and its fast-growing use in today’s construction markets and its popular use as a panel product in building construction.
• Examine mass timber’s unique attributes related to moisture, ability as a hygric buffer, and susceptibility to damage from elevated levels of moisture.
• Appraise and discuss findings from field studies related to moisture levels in mass timber components during and post-construction.
• Discuss analyses from laboratory evaluations related to mass timber moisture exposure and drying using water vapor permeable and nonpermeable protection strategies.
• Understand which areas of mass timber construction are necessary to mitigate moisture intrusion and its effects on occupant health and safety.
• Discuss the importance of risk management best practices for designing and installing mass timber.
  

Session Description
Mass timber (MT) has been used for thousands of years. However, only in recent decades has it been used as laminated panels in building construction, and this panel’s usage is growing in popularity. We will discuss publications that have studied the impact of MT moisture exposure and the need to protect the material from elevated moisture content. Laboratory test results on mass timber wetting and drying studies have shown how drying is essential to the material’s integrity. Field observations will be reviewed to understand moisture impacts during and post-construction. With its introduction as panels, new strategies must be employed for a successful installation to protect MT from moisture damage and ensure occupants’ long-term health and safety. This session will discuss moisture protection methods from manufacturing to post-construction. A risk management plan will be suggested to create a sustainable, stable structure and preserve the beauty of the mass timber building.

Session Description
Temple Emanu-El is a historic synagogue built in 1927 with distinct cast stone facades located in Providence, Rhode Island. Over many years and through various repair campaigns the cast stone facades exhibited significant freeze-thaw damage, blistered, and peeling coatings, as well as spalled concrete. Starting in 2015, Wiss, Janney, Elstner Associates, Inc. (WJE) collaborated with the congregation to develop, design, and execute a restoration of the sanctuary facades including replacement of the original cast stone units with new cast stone units. This presentation offers an insiders-view of the investigation, design, and challenges with recladding a historic composite mass masonry facade.

Knowledge Level: Intermediate
Recommended Prerequisites: General knowledge of roof framing, general knowledge of roof system design and ventilation, and general knowledge of condensation

Learning Objectives
At the conclusion of this session, participants will be able to:

• Discuss the common causes of condensation problems in low-sloped insulated framed roof systems and why these systems operate differently than similar vented steep-sloped insulated systems.
• Analyze how the use of pressurized ductwork within roof framing and how rooftop vents and exhaust fans increase the risk of condensation.
• Explain how recent building code changes that added requirements for unvented roof systems have reduced (although have not eliminated) the risk for condensation problems in these systems.
• Develop design and repair approaches for reducing the risk of condensation problems in these systems.

Session Description
Many low-slope roof systems installed over insulated framing spaces develop condensation problems. Unlike similar steep-slope roof systems that use convection- and wind-driven ventilation to dissipate moisture, effective venting is difficult to achieve in low-slope applications. The risk of condensation problems is especially of concern in framing spaces that are fully insulated to avoid the use of sprinklers in accordance with NFPA 13 requirements, which is the focus of this session. Interior air can flow into these insulated framing spaces through ceiling penetrations, interior walls, pressurized ductwork, and other sources. Solutions often involve using unvented roof systems that consider insulation and air barrier placement. Recent code changes have reduced (although not eliminated) the risk of condensation in unvented insulated roof framing systems. This session will review the causes of condensation in low slope insulated frame roof systems and methods for preventing them.

Learning Objectives
At the conclusion of this session, participants will be able to:

• Identify when a condominium board should take on a fenestration project based on age and performance of the systems, maintenance, and impact on tenants.
• Compare the benefits and drawbacks of both fenestration replacement and existing fenestration restoration, including code implications and performance requirements.
• Describe the common financial challenges and logistical impacts of pursuing a fenestration project at a condominium.
• Explain common tensions between a condominium board, property manager, and individual unit owners.
• Discuss the design professional’s role in advising/consulting on the project and risks faced by the design professional.

Session Description
Condominium fenestration replacement and restoration projects are intricate. While fenestration replacement/restoration is common for apartment buildings, executing at a condominium complex is challenging and requires careful planning and execution. Whether a condominium board opts for fenestration replacement or restoration depends on factors including logistical challenges, financial implications, ownership responsibility, code considerations, performance requirements, and impact on residents. We will review these factors from the design professional’s perspective and will discuss the complex dynamics between the property manager, condominium board, unit owner, and design professional throughout the project. This presentation is intended for design professionals who work with condominium clients and property managers.
