Summary
This study provides a comparative life cycle assessment (LCA) of a 4060 m2, 4-storey cross laminated timber (CLT) apartment building located in Quebec City, Canada and an equivalently designed building consisting of reinforced concrete slabs and columns with light gauge steel studded walls (CSSW). The emergence of CLT as a structural material that can be used in mid-rise building structures combined with limited work investigating the environmental performance of CLT in building applications provides the motivation for this comparative study.

Summary
This short report summarizes a life cycle assessment (LCA) study comparing a cross-laminated timber mid-rise building to the same building in concrete1. For more detail, refer to the original report which was the product of a rigorous, comparative LCA research project that complied with the international LCA standard ISO 14040:2006. In that study an apartment building in Quebec City, Canada was analyzed using two different building systems in order to understand the environmental footprint of each relative to the other. A LCA model was developed for a real, 4060 m2, 4-storey, cross-laminated timber (CLT) apartment building. The same building was then designed using reinforced concrete slabs and columns with light gauge steel stud walls. That design was intended as a building system that CLT would likely be compared with in the midrise construction market where CLT is likely to compete.

Summary
This document provides supporting information for LEED accreditation of the Wood Innovation and Design Centre (WIDC) in Prince George British Columbia. In particular, this document supports materials and resources pilot credit 63 - whole building life cycle assessment - in LEED BC+C: Core and shell v2009. The baseline building design for comparison is a reinforced concrete structure with light gauge steel envelope walls. The WIDC building is a mass timber building with cross-laminated timber used for the floors and stairwell/elevator core and structural insulated panels for the envelope walls. This work shows multi-storey office buildings in BC with mass timber structural systems and laminated veneer lumber curtain wall structures can have environmental performance improvements for non-renewable energy consumption, global warming potential, particulate matter formation and smog potential when compared to reinforced concrete buildings with aluminum-framed curtain walls. Reducing global warming potential requires future emphasis on reduced operational energy consumption.
