Summary
The Task Group on Combustible Construction is in the process of evaluating a proposed code change request related to buildings of encapsulated mass timber construction (EMTC). As part of the analysis of the code change request, an impact analysis is required that includes a cost-benefit analysis. Hanscomb was hired to provide a cost-benefit analysis and to compare the estimated value of the following: 1. The cost of constructing a building of mass timber (unprotected) versus a building constructed of encapsulated mass timber (e.g. mass timber protected with a double layer of Type X gypsum board) versus a traditional concrete and steel building. 2. The time to build a building of mass timber construction (unprotected) versus a building of encapsulated mass timber construction versus a traditional concrete and steel building. 3. The annual maintenance costs of building of mass timber construction versus a building of encapsulated mass timber construction versus a traditional concrete and steel building. For the purposes of this study two sets of conceptual floor plans and elevations have been created: 1. A 12 storey building with a Group C major occupancy (residential) where each storey is 6,000 m2 in floor area. 2. A 12 storey building with a Group D major occupancy (office) where each storey is 7,200 m2 in floor area.

Summary
Consuming over 40% of total primary energy, the built environment is in the centre of worldwide strategies and measures towards a more sustainable future. To provide resilient solutions, a simple optimisation of individual technologies will not be sufficient. In contrast, whole system thinking reveals and exploits connections between parts. Each system interacts with others on different scales (materials, components, buildings, cities) and domains (ecology, economy and social). Whole-system designers optimize the performance of such systems by understanding interconnections and identifying synergies. The more complete the design integration, the better the result. In this book, the reader will find the proceedings of the 2016 Sustainable Built Environment (SBE) Regional Conference in Zurich. Papers have been written by academics and practitioners from all continents to bring forth the latest understanding on systems thinking in the built environment.

Summary
This project aims to develop a new prefabricated wood / concrete floor system that is innovative and competitive in multi-storey wood buildings. The design of the floor will be carried out through a multidisciplinary approach that considers the composite action of the precast floor, the integration of sound insulation, vibrations, the weight of the structure, construction time and environmental impact. Among other things, the construction method and the use of ultra high performance green composite concretes with CLT slabs or GLULAM beams will be considered. The methodology includes digital analysis tools and a new method for the design of mixed structures as well as the life cycle tool. The laboratory proof of concept will assess the performance of the optimized floor system and compare it to existing floors.

Summary
On tall wood buildings, mass timber elements including CLT, NLT, glulam, and other engineered components absolutely need to be protected from excessive wetting during construction. This requirement precludes the use of many conventional cladding systems unless the building is fully hoarded during construction. The building enclosure and façade of UBC Tallwood House consists of an innovative prefabricated steel stud rainscreen curtain-wall assembly that is pre-insulated, pre-clad, and has factory installed windows. Design of connections and air and water sealing of panel joints and interfaces was carefully considered given the tall wood structure they were designed to protect. While steel studs were utilized in the panelized structure, feasible curtain-wall designs were also developed and prototyped for wood-framing, CLT, and precast concrete as part of the project. Looking ahead, there will continue to be innovation in design and construction of fast and durable facades for taller wood buildings. New prefabricated panel designs incorporating CLT panels and connection technologies from unitized curtainwall systems are already being developed for the “next tallest” wood buildings in North America.
