Interest in taller wood buildings utilizing cross laminated timber (CLT), nail laminated timber (NLT), and structural glued laminated timber (glulam) is growing rapidly in Canada and the United States. On the west coast, recently completed projects including the 97 foot tall, 6-story Wood Innovation and Design Center (WIDC) in Prince George, BC, the 180 foot tall, 18-story UBC Brock Commons Tallwood House in Vancouver, BC, and the upcoming 12-story Framework project in Portland, OR, have captured the attention of the international construction industry. Several other taller wood buildings are on the horizon and feasibility studies are currently being performed for mass timber buildings over 30 stories in height. Tall wood buildings have been a reality in Europe longer than North America, and there is much to learn from the European experience. However, conditions unique to the North American construction industry create many challenges for the design team in demonstrating the safety, durability, and economics of these buildings, all while forming public perception of wood at taller heights.

Guideline for the Two-Dimensional Simulation of Spandrel Panel Thermal Perfor...RDH Building Science
While the approach to thermal simulation of vision glazing areas is well documented by groups such as the National Fenestration Rating Council (NFRC), the approach to simulate opaque spandrel panels is not similarly documented. Furthermore, spandrel assemblies are substantially different from conventional
opaque wall assemblies (i.e., concrete, steel stud, wood stud, etc.). To address this industry need, RDH in partnership with the Fenestration Association of BC (FENBC) and funding from BC Housing has developed a procedure to determine spandrel panel U-factors using common industry tools and familiar methods. The methodology includes consideration of various spandrel panel arrangements and builds off the existing NFRC 100 simulation methodology. The objective of this procedure is to document a reasonably accurate and practical approach to determine opaque spandrel area U-values with higher precision and uniformity. This allows for both the accurate representation of these systems with regards to code compliance and
energy modelling, as well as the fair comparison of competing products.

2nd Generation Lead Free Alloys: Is SAC the Best We Can Do?Cheryl Tulkoff
oWhy did SAC305 become the standard LF alloy? SAC was never considered an ideal replacement for eutectic SnPb, it was simply the best choice at the time. It was readily available, had a reasonable melting temperature and had the least reliability issues compared to other options.
oHowever, SAC305 has weaknesses that can be overcome with newer alloys. SAC is a precipitation hardened alloy which means the microstructure and mechanical properties are significantly impacted by reflow temperature and time, cooling rate, and aging (dwell times). It is undesirable for the properties of the solder to be so dependent on the assembly conditions and the customer use environment.
oThis presentation addresses the latest research and reliability results for 2nd generation lead free (LF) alloys.

Daniel Skog, Communications Officer, Malmö, Sweden
Closing the loops – sustainable systems for energy, waste and water and in the Western Harbour, Malmö, Sweden” Historically, Kockums shipyard was located in the Western Harbour which today hosts thousands of apartments and offices. The first development, Bo01, was designed to use and produce 100% locally renewable energy over the course of a year. Buildings receive energy from solar, wind and a heat pump that extracts heat from an aquifer that facilitates seasonal storage of heat and cold water in the limestone ground. The different stages in the Western Harbour have piloted different waste separation systems. Food waste is gathered in storage tanks and transported for biogas production. All areas in the Western Harbour have good access to walking paths, bike lanes, buses and car pools.
Re-Energizing Our Cities: From District to Specific - Integral GroupToronto 2030 District
Dave Ramslie and Gerry Faubert, Principals, Integral Group
Reenergizing our Cities! – Integrated District Scale Energy Planning
Investment in our buildings and infrastructure has never been more timely. Energy solutions that work for both new development and for the retention and re-imagining of our existing buildings are possible today. The scale and application of these solutions from grass roots community engagement programs, to retro-commissioning, big data and the development of large sale renewable energy solutions can work together to lower emissions and improve our collective quality of life. Using case studies such as the development of new district ambient loop in downtown Vancouver using existing fire protection infrastructure and the promotion of deep green retrofits in multi-unit residential buildings through the Condo Retrofit Assistance Financing Trial (CRAFT) Dave Ramslie and Gerry Faubert will examine how a variety of solutions deployed at the neighborhood level can be aligned to achieve significant community wide energy savings and economic revitalization.

If necessity is the mother of invention then uncertainty is the seed for innovation. We live in uncertain times. Our trusted climate models and long-cherished engineering tools and formulas are being severely tested and are often incapable of coping with inherent uncertainties of our natural and human environments. Challenged by the severe climate events, economic and population pressures and aging infrastructure, cities are forced to reconsider the concepts of planning and scale. In this presentation we will explore the idea of urban infrastructure design and planning derived from a new paradigm in water management. Focusing on what we already know and presenting tools we already posses, the presentation discusses how to transition from current deterministic approach in planning to a more adaptive approach that incorporates water management using a post-normal systems approach. Technical, regulatory and design examples will be provided to highlight the transition already underway. Examples include distributed water reuse and recovering energy and other resources from wastewater.
What is "Model" Sustainability? UniverCity's Journey Toward Sustainability T...Toronto 2030 District
Dale Mikkelsen, Director of Development, SFU Community Trust
Simon Fraser University (SFU) created its Community Trust to develop a model community on about 65 hectares of land surrounding SFU’s Burnaby campus in British Columbia.
That ‘sustainable community on the mountain’ became UniverCity, the award-winning, mixed-use, transit-oriented district with a diverse range of housing choices, shops, services, and amenities. And the UniverCity Childcare Centre is expected to be the first building in Canada to meet the Living Building Challenge, the most ambitious rating system in North America for environmentally sustainable architectural design.
A model for practical and affordable sustainability, UniverCity also generates endowment wealth to support teaching and research at SFU.
As the Director of Development for SFU Community Trust, Dale Mikkelsen is charged with raising the bar of sustainable community planning to ensure UniverCity remains on the leading edge of energy efficiency, material conservation, healthy environments and community building.
Mikkelsen brings a wealth of experience to the UniverCity project having been the lead project planner for the City of Vancouver’s 2010 Athlete Village, the City of Vancouver’s Green Building Planner, and a Board Member for the International Living Future Institute.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

3. Why does it matter?
• Codes demand it
• Substantial portion of construction budget – 20% range
• Integration with HVAC requires that the building envelope
perform
• Sustainable buildings often incorporate innovative assemblies
and materials
• Envelope failure can require costly repairs to re-establish the
design intent
• Envelopes are complex systems with shared responsibilities
and are not typically commissioned
