Cross-Laminated Timber (CLT) is an innovative structural system based on the use of large-format, multilayered panels made from solid wood boards glued together, and layers at 90 degrees. This cross-laminated configuration translates into panels that are monolithic, stable, and experience minor shrinkage, which allows them to be used for the...
This pilot project in the metropolitan Boston area will seek to mobilize a combination of public incentives and private financing to monetize – or bring value to – the carbon benefits of mass timber. The goal is to both encourage early adopters concerned about mass timber’s costs and to bring mass timber construction to the city at a scale and in an ongoing manner that will provide a long-term market for local timber while developing an urban “carbon sink” to attract ongoing private investment for voluntary carbon offsets markets. The project will serve as market development to encourage planned mass timber manufacturing plants to open in New England, as incentive for improved forest management for carbon plans being encouraged by public and private groups in Massachusetts and throughout New England, and as a blueprint for other U.S. cities and states seeking to reduce greenhouse gas emissions, increase development, and bring value and new forest product manufacturing to surrounding rural, forested areas.
The primary outcome of this work is to provide integrated analysis of the environmental, financial, and social benefits and costs of using CLT in tall wood buildings. Secondary outcomes will be (1) information, including a design team checkoff that can be used to inform the building community as they make decisions on specific, new building projects, and (2) an informational foundation for these stakeholders and others to begin to evaluate the complex tradeoffs between, and optimization of, environmental, financial, and social benefits and costs.
Recent changes to the National Building Code of Canada (NBC), and a trend towards more diversified housing options, have meant that many Canadian jurisdictions are acting quickly to capture the environmental, economic and social benefits of higher wood buildings. The 2015 NBC now permits wood frame construction to be 6 storeys high. Today, already 75% of Canadians live in jurisdictions that allow 6 storey wood frame construction. With the overall benefits of using wood as a building material well documented, Atlantic WoodWORKS!
studied the opportunities for 6 storey wood construction in Atlantic Canadian Centres. The research included a comprehensive market study and projections for mid-rise demand in
four major centres in Atlantic Canada, a review of recent and upcoming planning changes in major Atlantic Canadian cities and a full cost analysis, comparing wood construction to three
other construction methods in use in the Atlantic market using a real-life wood mid-rise structure built by an experienced builder.
