As part of its work on massive wood construction, FPInnovationsrecently published the Design Guide for Timber-Concrete Composite Floors in Canada. This complete document, which is a complementary tool to the Canadian CLT Handbook, addresses different aspects related the design of wood floors covered with a composite concrete slab, a massive wood building approach that is little known in Canada but which could be better exploited. Timber-concrete systems consist of two distinct layers, a timber layer and a concrete layer (on top), joined together by shear connectors. The properties of both materials are then better exploited since tension forces from bending are mainly resisted by the timber, while compression forces from bending are resisted by the concrete. …You are interested in learning more on this subject?

The Province is encouraging the use of mass timber in the construction industry with the hope of breathing life back into our beleaguered forest sector. Parliamentary Secretary for Forestry, Ravi Kahlon has been given task of overseeing the expansion of use of mass timber in BC buildings. On the NL Morning News, he was asked if it can help communities that have seen mass closures like Chasm and Vavenby. “Well I certainly hope so. I mean, I’m not going to say that next week we’re going to have CLT facilities or mass timber facilities pop up,” he said. …Kahlon admits there’s many factors at play. …“We have to look at the supply and demand. How do we encourage more supply to come on line of mass timber? And, how do we also create that demand by building public buildings with mass timber?”

In the history of architecture and construction, there has never been a building material that has had as rough a ride as wood. …It has a limited record of use from ancient history simply because of its inability to withstand the ravages of time. Furthermore, its combustibility has out and out vilified it. …For this reason alone, building codes around the globe have not seen significant change in regards to the use of wood for some time. This is reflected in Canada where, since the 1950’s (and up until just recently), wood buildings have not been permitted to be built above four storeys. …As such, this new book provides an updated introduction and conclusion to the original 2017 edition, to discuss more recent achievements and breakthroughs in tall wood building science, including five new case studies added to the original book’s thirteen.

In May, Alphabet’s Sidewalk Labs announced that it would cancel its high-profile Quayside project because of “unprecedented economic uncertainty.” The statement marked the end of a three-year initiative to create a living, urban “testbed for emerging technologies, materials, and processes.”  …But the project’s cancellation changes little regarding mass timber’s future. Indeed, the true legacy of the Sidewalk Labs Toronto project lies not in its smart-city applications for human interaction, monitoring, and algorithmic anticipation, but with that much older human activity—wood construction. Mass timber represents a massive step forward for design, carbon-capture goals, and green efficiencies. CLT is as strong as steel and offers the same—or better—fire-retardation properties. It also allows for faster builds (35 percent quicker than typical timelines), which avoids tying up city streets with cement mixers.

…From the outset of the coronavirus pandemic, one message has been repeated loud and clear…: wash your hands with soap thoroughly and frequently to help protect yourself and others. But while proper handwashing has been widely discussed and accepted, proper hand drying has not—even though improper hand drying can undo the many benefits of handwashing. According to research from the Mayo Clinic, bacteria are more likely to be transmitted from wet skin than dry skin, making proper hand drying a critical component of the hand-hygiene process. …The Mayo Clinic …concluded that, from a hygiene viewpoint, paper towels are superior to electric air dryers. The review also noted that paper towels can dry hands efficiently, remove bacteria effectively, and cause less contamination in the restroom environment.

Composite binders are important materials used in furniture, flooring and other consumer products, but they can pose health hazards. Now, Purdue University researchers have developed a lower-cost, sustainable and greener method for producing composite boards…. Fabrication of many composite boards requires the use of formaldehyde-based resin binders that are released into the home environment over time, posing significant health hazards since formaldehyde is a known carcinogen. “The uniqueness of our method is that we take non-food-based biomass such as wood chips, sawdust or rice straw, and put it through a process to extract lignin-like material that can then be used as the main component in a non-formaldehyde binder system for composite boards,” said James Caruthers, Purdue’s Gerald and Sarah Skidmore Professor of Chemical Engineering. “Our method is sustainable and green because lignin is a waste byproduct and one of the most abundant biopolymers on Earth.”

But how true is the positive sustainability line?  We often have to take the experts word for it, and relying on the word of others can at times be very unprofessional.  People who push a concept may have ulterior motives or stand to benefit from the push, and we know that data and statistics can be presented to favor a point of view. Without authenticating the scientific data on timber’s sustainability, from a superficial lay-persons view, there are concerns.  Of course, timber can be regrown, which is its big sustainability selling point, but is the whole concept debatable?

In 2019, a masterpiece of engineering opened its doors in Steinberg am See, Germany. The worldwide largest walkable wooden sphere (capacity for 950 visitors at a time) by inMotion Park Seenland GmbH is superlative in many ways. With a weight of over 500 tons, a height of 40 metres and a diameter of almost 50 metres, this project can already be seen from afar. 627 m³ of glued laminated timber, 190 tons of steel parts, 40,000 screws, 18,000 bolts/building screws/dowels, 3,300 m² cladding panels, and 2,200 meters of railing – these are just a few of the key features of this enormous project. The twenty external structural glulam elements have an arch engraving of around 15 metres and a total length of 55 metres. …This made it possible to provide the glued laminated timber elements at the factory in Kleinheubach with two joints and to prefabricate them completely.

Envisioned by multidisciplinary studio AEMSEN, Barbizon is a modular residential complex that proposes a new urban living concept for barbizonlaan in capelle aan den ijssel, the netherlands. based of the principle of creating future-proof, sustainable and affordable housing, the project focuses on the use of a prefabricated timber structure that can be stacked to establish social interaction and a balance between the city and green spaces.  Barbizon has been designed as part of the redevelopment of the sites on the barbizonlaan, however, AEMSEN also proposes that the concept could be adapted to other locations and briefs. this specific scheme contains 112 apartments in 16 different housing types, varying in size from 45 m2 to 120 m2. the factory-built CLT modules are stackable and switchable without additional auxiliary construction. this dry construction method with biobased materials and gas-free apartments provides an attractive ecological residential complex.

ENGLAND — The Government’s recent consultation on extending the ban on combustible materials to more building types and lowering the height restriction in England. Andrew Carpenter, Chief Executive of the Structural Timber Association discusses how this ruling if adopted will severely inhibit our ability to decarbonise the UK construction industry. …Roger Harrabin, the BBC’s Energy and Environment Analyst ….rightly pointed out that this action would contradict other advice to increase timber construction because trees lock up climate-heating carbon emissions. But this also flies in the face of the support that the government itself has shown for offsite manufacturing to deliver much needed housing –  the most efficient of which are timber-based systems. …Furthermore, it is clear that the UK is out of step with the approach being taken by leading economies in Europe.

Swedish engineering company Modvion has been granted €6.5m in EU funding to support manufacturing of its wooden turbine towers. …Funding will be used to build a development factory in the Gothenburg area, which will make a 100-meter unit for Varberg Energi. The company, which installed a first 30-metre unit on the island of Bjorko in April, has also signed declarations of intent with Rabbalshede Kraft for 10 towers, each at least 150 metres high. “This support from the EU is clear proof of the enormous potential of wooden wind turbine towers… We are now one step closer to being able to offer commercial, climate-neutral wind turbine towers,” said chief executive Otto Lundman. “We are seeing an enormous demand for our wooden wind turbine towers. Laminated wood is stronger than steel at the same weight and by building modularly, wind turbines can be made both higher and cheaper.”

Latvijas Finieris has together with Stora Enso taken the next steps towards replacing phenol – in resins used in plywood – with lignin. This new lignin-based glue significantly reduces the carbon footprint of plywood products all the way from production to final end-use applications without compromising on technical performance. Months of co-development, trials, industrial tests and commitment from both companies eventually led to the development of a lignin-based resin ideal for plywood products. …“Results of industrial production trials show that all technical properties of RIGA Plywood remain unchanged when the environmentally friendly glue RIGA ECOlogical is applied, containing Stora Enso’s kraft lignin Lineo™. Of course, it’s only the beginning. Our aim is to develop completely fossil-free plywood glue in the future, although there is still a lot of research work ahead to achieve that,” Būmanis concludes.
