Modular Mass Timber for Housing Construction

This research aims to understand the intricacies deploying mass timber as an element of modular construction, and their potential integration into the housing market. However, the successful implementation of Modular Mass Timber (MMT) depends on understanding the complex interplay of technical, economic, and managerial factors. This research aims to identify, evaluate, and model the Critical Success Factors (CSFs) that influence MMT adoption in housing projects in the United States. A multi-method approach was employed, combining a systematic literature review and semi-structured expert interviews to collect qualitative and contextual data. Fifteen CSFs were identified, seven from the literature and eight additional factors from expert insights. The interrelationships among these factors were analyzed using Total Interpretive Structural Modeling (TISM), supported by MICMAC analysis to classify factors based on their driving and dependence powers. The resulting hierarchical framework reveals sustainability and logistics as dominant drivers, with time, quality, and efficiency serving as foundational operational enablers. The study further develops a strategic implementation guide to assist developers, designers, manufacturers, and policymakers in prioritizing interventions, optimizing resources, and improving project outcomes. Overall, the findings advance theoretical understanding by providing a structured, system-level view of CSFs for MMT adoption and offer practical insights to facilitate scalable, cost-effective, and environmentally sustainable housing solutions.

Exploring the Impact of Knots in White Pine on Consumer Preference and Pricing

Biophilia describes the innate human connection to nature, with wood functioning as a biophilic material that supports human well-being. Although extensive research has examined the psychological and physiological impacts of wood environments, the specific effects of wood defects remain largely understudied. Incorporating wood with defects into design is essential for improving material efficiency, particularly given mass timber’s role in reducing building-related carbon emissions and the fact that approximately 30-40% of harvested wood is discarded due to defects. Mass timber floor and roof deck design primarily depends on stiffness and, therefore, is generally less affected by knots than other structural members. However, material with knots is often excluded from these visible applications due to perceived consumer preference. Therefore, a greater understanding of consumer preferences for wood with defects can potentially enhance utilization while still meeting performance requirements. A previous study (Chapagain & Crovella, 2025) examined physiological responses, creativity, concentration, and psychological reactions to wood with and without defects. Building on that work, this study investigates how knots in Eastern white pine influence consumer preferences and pricing in relation to cultural background. The findings suggest that negative perceptions of wood defects may not be universal, that consumer preferences may affect market valuation, and that cultural differences may shape how environments with wood defects are perceived and experienced.
