DESIGNER’S CHOICE

Tools to help you test and trial different timber design options

Mass timber products, combined with a growing number of hybrid structural solutions, are opening up new possibilities for design teams. As the choices increase, so too does the need to narrow down to the one best suited for your project. To help you, check out some of our latest tools, released April 2023, that can assist in the conceptual testing, analysis and trialling of different options.

1. Mass Timber Navigator: understanding energy and code considerations

Launched February 2023.

Test design variables and pre-calculated energy consumption results for eight typical mass timber building types. 

Quantify and evaluate construction costs, code compliance and energy performance on your next mass timber project with the Mass Timber Navigator tool. It includes comparisons of eight typical mass timber buildings ranging from 3- to 12-storey residential, office, civic and industrial project types situated in four B.C. regions: Vancouver, Kamloops, Prince George and Fort St John. 

You can change various design specifications on each building type and compare performance metrics. It can also help inform order of magnitude (or class D) proforma estimates.

2. timberX: a comparative tool for steel, concrete and timber

Launched February 2023.

Evaluate the benefits of mass timber compared to steel and concrete early in the design process.  

Created for developers, architects and engineers in the early stages of a building project, timberX, evaluates four key considerations: weight, depth,  approximate cost and embodied energy of different building systems. Its easy-to-use interface includes comparative data at a glance along with visual aids to illustrate the pros and cons of each option.

3. Building Information Modelling (BIM) for Wood Buildings: An Introductory Guide & REVIT Details

Gain a solid grasp of BIM fundamentals and how BIM can help streamline wood design construction. 

BIM for Wood Buildings: An Introductory Guide, developed by Scius Advisory and BIMOne, is a good starting point for design teams interested in using advanced technologies like BIM to realize the benefits of digital fabrication and off-site construction, specific to timber construction.  

The guide includes an overview of how to set up a BIM project to support the design of advanced wood buildings. Along with practical advice, it includes four case studies complete with 3D Revit details to demonstrate how parametric information modelling can inform design analysis, cost estimating, schedule planning and construction sequencing.

Carbon Crunch

Calculating the environmental impact of timber buildings

Curbing the impacts of carbon emissions is an important benefit of building with wood. And in some cases, you may want to quantify that positive contribution with these carbon tools. Check out these tools to help you crunch the numbers when it comes to the carbon savings mass timber can provide.

4. National guidelines for whole-building life cycle assessment

Understand whole building life cycle assessment (wbLCA) industry standards and best practices and how they can inform construction planning, policy and/or software.

wbLCA is widely considered the best method for examining the embodied carbon of buildings because it considers the life-cycle greenhouse gas emissions associated with material production, transportation, construction, use, and eventual disposal. To improve the quality and consistency of wbLCA as applied to buildings and assist in interpreting relevant international standards, Natural Research Council Canada, in collaboration with the Athena Sustainable Materials Institute, has produced the National Guidelines for Whole-building Life Cycle Assessment. It’s a great place to start if you want to understand the calculation of reliable life-cycle benchmarks better, establish policies based on wbLCA or develop software focused on automating wbLCA analysis.

5. Carbon Calculator by Canadian Wood Council

A quick way to calculate the carbon benefit of your next wood project. 

If you’re looking for a relatively simple way to estimate the impact of wood products used in a particular building—along with the associated carbon benefits—look no further than the Carbon Calculator by Canadian Wood Council. After inputting wood volumes, the tool estimates how much time it takes Canadian and U.S. forests to grow that volume of wood along with the associated carbon benefits.

The Canadian Wood Council Carbon Calculator includes easy-to-follow instructions on each input tab of the tool. After completing each section, the tool calculates the estimated carbon benefits of your building project.

6. Athena Impact Estimator for Buildings

An in-depth software application that can calculate the environmental impact of over 1,200 structural and envelope assembly combinations. 

The Athena Impact Estimator for Buildings has been helping building professionals simplify the complex life-cycle assessment (LCA) methodology that goes into crunching the real numbers on embodied carbon and other environmental impacts for two decades. Results are instantly displayed for embodied fossil energy use, as well as global warming, acidification, eutrophication and smog potential.

The Athena Impact Estimator for Buildings can make multiple comparisons at once. Design teams can change and substitute materials for helpful side-by-side comparisons. The software can quickly generate reports, graphs, tables, summary measures and bills of materials with just a few clicks.

7. Embodied Carbon PathFinder

Understand the impacts of embodied carbon and make better-informed decisions when tackling multi-family projects. 

If you’re looking to learn more about the impacts your residential design choices can have on embodied carbon, check out the Embodied Carbon PathFinder. The tool provides a visual graphic along with table data to illustrate the global warming potential (GWP) of various design options for stacked townhouses, mid-rise and high-rise wood construction. It is a companion tool to the Operational Energy PathFinder which analyzes the design variables that affect energy use and greenhouse gas emissions due to building operations.

MUST-HAVE RESOURCES

Go-to guides for building with mass timber

Over the past few years, the use of cross-laminated timber (CLT) and nail-laminated timber (NLT) has quickly grown and been used in a wide variety of building types, here in B.C. and around the world. At the same time, mass timber buildings are getting ever taller and design teams are looking to use more sophisticated modelling in the planning of such buildings. With mass timber’s rise in popularity, there are a growing number of comprehensive best-practice handbooks developed by a consortium of experts. 

8. NLT Design + Construction Guide (2017)

Everything you need to know about NLT construction and design. 

The NLT Design + Construction Guide is one of the only comprehensive NLT resources available that combines design, construction and fabrication best practices illustrated using real-world case studies. Consistent with current Canadian codes and standards, the guide focuses on considerations for NLT floor and roof systems. While NLT has been used for more than a century, it is once again growing in popularity—and modernized through prefabrication techniques—for its cost-effective aesthetically pleasing benefits.

There’s also a U.S. version for design teams working in the United States and a second Canadian edition is slated for publication in 2024.
