Summary
The purpose of this research is to investigate what differences, if any, exist between the modeled energy consumption and building envelope performance of the Wood Innovation Research Laboratory (WIRL) building following eight months of in-situ data collection. The WIRL building was completed in July of 2018 by the University of Northern British Columbia (UNBC) and is located in Prince George, British Columbia. Built in partnership with the Province of British Columbia, the building was designed to meet Passive House standards, a building certification system that requires the building to have low energy input requirements due to high levels of thermal insulation and minimal air leakage. To ensure the building achieves the established energy use targets set forth under the Passive House certification system, a computer model of the proposed building design must be completed prior to the start of construction using the Passive House Planning Package (PHPP) software. Inputs to the model include envelope design, mechanical energy use, building location and airtightness value. Key outputs included the predicted annual heating demand (kWh/m2a), total primary energy demand (kWh/m2a), and air tightness of the building envelope (ACH@50Pa). Based on the final building design model and test results achieved following completion, the WIRL building was deemed to have met all Passive House requirements and certification was achieved. To complete on-going data collection of the in-situ performance of the WIRL building, temperature and humidity sensors were installed in two of the exterior wall assemblies and the building’s floor. In addition, gas and electrical energy use meters were installed to monitor the building’s energy consumption. The installation of all equipment was made possible by Forest Innovation Investment through their 2018/2019 Wood First Program.

Summary
Wood structures such as the Wood Innovation and Design Center in Prince George and the UBC Tallwood House, an 18 storey, 53-meter-tall mass timber hybrid building are examples of new and innovative wood structures that encompass new construction techniques, unique materials and novel building practices. Empirical data on the condition of critical components and access to the real-time status of the structure during construction gives Architects, Engineers and Contractors critical information to make informed decisions to either validate or improve the construction plan. Data recorded during the life of the building helps validate the design decisions and proves the viability and feasibility of the design. Methods and practices used to monitor both the moisture performance of prefabricated cross laminate timber (CLT) as well as the vertical movement sensing of the building during and after construction are explored in this paper. Moisture content of the CLT panels has been recorded from manufacturing and prefabrication to storage, through transport and during installation and will continue throughout the service life of the building. The calculated and expected displacement of the wood columns is scheduled to take several years as the structure settles, however a first-year analysis and extrapolation of the data was conducted. Monitoring during transport, storage, and construction proved that CLT panels were resilient to moisture issues while in the manufacturers storage, but prone to direct exposure to moisture-related problems regardless of the precautions taken on site. Despite construction during typical Pacific Northwest rain, informed decisions were made to ensure the panel moisture content could decrease to acceptable ranges before continuing to secondary construction phases. The moisture trends observed in the building were proportional to the control samples as both were subjected to similar environmental conditions.
