What’s World Wood Day?




World Wood Day (WWD) is known to be a cultural event that is celebrated every year on March 21 highlighting wood as an Eco-friendly and renewable bio material. WWD’s main objective is to raise awareness and understanding of the key role wood plays in a sustainable world in the future through forest biodiversity conservation and the importance and true value of its responsible use.

The International Wood Culture Society (IWCS) first proposed about the World Wood Day in 2010 along with their operational partners and in March 21, 2013, the first World Wood Day was celebrated in Tanzania in a joint effort with international organizations and Tanzania Governmental bodies. WWD is currently observed  on the same day as the International Day of Forest to extend the idea of applying a cultural approach to disseminate the concept of “Wood is Good” and incorporate it into people’s lives.


World Wood Day Foundation is a  non-profit organization established in California after the first celebration of World Wood Day 2013 in Tanzania when a need for fund raising became an imperative and the need of a managing body was given priority. This is the response to the outcome of the WWD 2013 celebration in 2013 to manage funds and grants to carry out the foundation’s mission.

World Wood Day Foundation Mission:

  • To raise public awareness of wood as an Eco-friendly material and encouraging academic research and responsible wood usage for a sustainable future.
  • To advocate and annually celebrate WWD on March 21
  • To manage funds and grants for WWD and global research, educational and promotion of wood culture.

Do-It-Yourself Jewelry Board

All my necklaces, bracelets and other jewelry have been lying all around the house for far to long: in the bathroom, in the wardrobe, in the kitchen… And that’s a bit sad since most jewelry is beautiful and deserves to be displayed.


I made my jewelry board from a piece of driftwood and some pretty sticks I found in the Hurst behind our house. 


I painted the sticks with water colours. At first I had an idea about just using a limited number of colors but of course I couldn’t stick to that plan. Instead the whole rainbow got represented but I saved a lot of the raw natural wood too, and it makes a beautiful contrast to all the colors.


I drilled holes in the driftwood and carved the sticks so they would fit in the holes. Then I used wood glue to make them stick.

Three years ago I wrote about Waugh Thistleton’s Timber Tower, what was to be the tallest wood residential building in the world. It’s up now, and Craig Liddell, commercial director for KLH UK, the builder, spoke at the Green Building Festival in Toronto. The building is a remarkable mix of design and wood technology, all completely invisible to the people inside.

The building is made from prefabricated cross-laminated timber (CLT) panels, made in Austria from sustainably harvested lumber. They are strong; Craig says they can go up to fifteen stories. They are fire resistant; unlike steel, it doesn’t lose its strength when it gets hot. In a fire, the char that forms on it is actually an insulator.

The panels are connected with angles, and proprietary connectors; here you can see a balcony detail, with waterproofing applied on site after the panels are connected. The amount of waste from the entire construction process could fit in a wastebasket.

I think it unfortunate that they covered up all of that warm wood; it was gorgeous and now the same view just shows ordinary drywall. But that was evidently the point, to show that a building made of wood was in the end, looked no different than conventional construction.

Except there is one big difference: the manufacture of concrete is a huge producer of carbon dioxide, aggregate mining scars our countryside and it takes four times as long to build. Wood is renewable and building with it sequesters carbon dioxide for the life of the building, in this case a difference of 306 tonnes of CO2.

In my post of a few years ago asking, Concrete: Can it be Green?, a commenter responded:


Concrete isn’t a benign substance, but then I don’t know what human-made material IS, and our urbanized & urbanizing reality dictates that we use it. I love wood, but there are just some structures you just can’t build out of sticks!

KLH and Thistleton Waugh demonstrate that you can do a lot more than we thought. With so much wood going to waste because of pine beetle infestation, it is a shame that they don’t do this in North America.



Tall Wood: Architect Gives Away Technology To Build Wood Buildings Thirty Storeys High

By: Lloyd Alter

Wood is perhaps the greenest building material; it is a renewable resource that absorbs carbon dioxide as it grows, which is sequestered in the wood when it is cut into building materials. But until recently its use was limited to low rise structures due to concern about the fire hazard.

But it has been known for centuries that heavy timber actually performs better in fire than structural steel; a layer of insulating and fireproof char forms on the outside of it when it burns, protecting the structural integrity of the wood. (It is designed bigger than it needs to be to allow for this char layer.) The recent development of cross-laminated timber creates a building material with all of the virtues of heavy timber without the need for the big trees. We’ve previously shown Waugh Thistleton’s CLT building in London, 9 storeys of wood.


Now a new Canadian study demonstrates a hybrid system that has been engineered for buildings up to thirty stories. In Tall Wood (PDF Here), Author and architect Michael Green makes THE CASE FOR Tall Wood BUILDINGS: How Mass Timber Offers a Safe, Economical, and Environmentally Friendly Alternative for Tall Building Structures.

He starts off on the wrong foot with (I think) a dreadful name, FFTT, standing for “Finding the Forest Through the Trees”.

The acronym speaks to the idea that much of the sustainable building conversation is focusing on minutia. While even the minutia contributes and is important, the big systemic change ideas are what we believe will be necessary for the built environment to tackle the scale of the climate change and housing demand challenges facing the world. FFTT is a contribution to hopefully many significant shifts in the way we approach buildings in the next decades. The goal is simply to focus on the forest but never forget the trees.

But after that he reaches for the sky.


The structural details of FFTT as a “strong column – weak beam” balloon-frame approach using large format Mass Timber Panels as vertical structure, lateral shear walls and floor slabs. The “weak beam” component is made of steel beams bolted to the Mass Timber panels to provide ductility in the system.

The system differs from pure CLT plays in that it also uses Laminated Strand Lumber (LSL, trade name Parallam) and Laminated Veneer Lumber (LVL). But the reasons for using wood in whatever form remain the same:

Wood is typically the best principal material available for building structures with respect to embodied energy use, carbon emissions and water usage. Sustainable forest management and forest certification are a necessary precursor to the increased use of wood. The ability of the public to embrace an increase in wood buildings comes with a strong understanding of the overall impact on BC, Canada and the world’s forests. Deforestation is a critical contributor to anthropogenic climate change. The concept of using more wood will only be fully embraced when the harvesting of wood is understood to be truly sustainable and responsive to the environment.


Sustainably harvested wood is the resource that lasts forever, employs local trades and minimizes shipping. Thanks to the Mountain Pine Beetle, we have more of it than we could possibly use.

Architect Michael Green and Engineer J. Eric Karsh have produced a remarkable 240 page document. Furthermore, they could have patented or licenced it but are giving away all of their research under a Creative Commons licence, writing:


The scale of the opportunity contained in these solutions is enormous, and there will be meaningful opportunities for some organizations, companies and individuals to profit from pursuing these ideas. The decision of the authors and originator of these ideas is to encourage an Attribution Non Commercial Share Alike approach (see below for definition) that encourages adoption of FFTT CC into mainstream building practices. This decision underscores our belief that these ideas are stepping stone concepts to the types of systemic change necessary to address climate change issues in the building industry with the increased use of sustainably harvested wood in building structures.

Michael Green is known to TreeHuggers as the author of The Case for Tall Wood Buildings. However when he spoke at the Wood Solutions Fair in Toronto it became clear that he is perhaps the material’s greatest proselytizer , both in his speaking and in his body of work. He makes an audacious claim:

Wood is the most technologically advanced material that we can build with.

I asked Green to speak about this in a little more detail in a brief, noisy interview. He notes that architects are stuck in a glass and steel mindset, and that man-made materials are nowhere near as good as what Mother Nature has made. He wonders why sticking solar panels on the roof of a concrete or steel building is considered green when the actual building is made of materials that are not. Green says that the culture of concrete peaked with Le Corbusier in 1929 and steel with Mies Van Der Rohe in 1950; now is the time for wood.

The Earth grows our food; The earth can grow our homes. It’s an ethical change that we have to go through.

He is right; there are millions of hectares of wood in North America dying right now from the onslaught of the Mountain Pine Beetle; it is almost unethical to use anything else. But innovation in architecture is incredibly slow; the building codes are not performance based, so change takes years, and we have to “change society’s perception of what is possible.”

Michael Green’s work certainly is a testament to wood; this atrium in the North Vancouver City Hall is a clever use of large panels of laminated strand lumber that is normally cut up for lintels and beams. Green tells Wood Solutions:

Engineered structural timber materials with many applications have emerged from the realisation that we can chop wood up and glue it back together; that we can use the fibre, which is the basis of wood, to its best advantage. For example, we used jumbo sheets of LSL (laminated strand lumber), which is made from compressed timber waste, to construct a large building very quickly. This was the North Vancouver City Hall project, where we cross laminated three sheets measuring 12 by four metres to create a beautiful wood structure that is also exposed as its ceiling.

Also dear to my heart is Green’s attitude about learning from the past.

More broadly in our architectural practice, we started to look around at existing timber structures and ask, “How can we learn from the past?” For example, at the turn of the 20th Century the timber barn on the Vanderbilt family farm in Vermont was the single largest volume space in the United States. The 37-metre high wooden Church of Transfiguration in Russia that was built in the 17th Century is still standing. When we started renovating a 100-year old building in Vancouver’s Chinatown we discovered that all the walls were made with ‘mass timber’, which was common practice at that time. We saw that we could learn from other cultures about their building practices and traditions to improve our own work. We also discovered that we build with wood now pretty much the same way as we did 500 years ago.

As for Green’s 30 storey wood towers, he says that he picked that number for its impact; had he said ten storeys, people might not have paid attention. Many thought he was nuts, but now major American architectural firms are in serious discussions with him about building wood towers for offices and residential projects. We are going to be hearing a lot more about tall wood, and a lot more about Michael Green.

Wooden Pavilion – University of Stuttgart

By: Arch Daily

Source: http://www.archdaily.com/200685/icditke-research-pavilion-icd-itke-university-of-stuttgart/

In summer 2011 the Institute for Computational Design (ICD) and the Institute of Building Structures and Structural Design (ITKE), together with students at the University of Stuttgart have realized a temporary, bionic research pavilion made of wood at the intersection of teaching and research. The project explores the architectural transfer of biological principles of the sea urchin’s plate skeleton morphology by means of novel computer-based design and simulation methods, along with computer-controlled manufacturing methods for its building implementation. A particular innovation consists in the possibility of effectively extending the recognized bionic principles and related performance to a range of different geometries through computational processes, which is demonstrated by the fact that the complex morphology of the pavilion could be built exclusively with extremely thin sheets of plywood (6.5 mm).

BIOLOGICAL SYSTEM The project aims at integrating the performative capacity of biological structures into architectural design and at testing the resulting spatial and structural material-systems in full scale. The focus was set on the development of a modular system which allows a high degree of adaptability and performance due to the geometric differentiation of its plate components and robotically fabricated finger joints. During the analysis of different biological structures, the plate skeleton morphology of the sand dollar, a sub-species of the sea urchin (Echinoidea), became of particular interest and subsequently provided the basic principles of the bionic structure that was realized. The skeletal shell of the sand dollar is a modular system of polygonal plates, which are linked together at the edges by finger-like calcite protrusions. High load bearing capacity is achieved by the particular geometric arrangement of the plates and their joining system. Therefore, the sand dollar serves as a most fitting model for shells made of prefabricated elements. Similarly, the traditional finger-joints typically used in carpentry as connection elements, can be seen as the technical equivalent of the sand dollar’s calcite protrusions.

MORPHOLOGY TRANSFER Following the analysis of the sand dollar, the morphology of its plate structure was integrated in the design of a pavilion. Three plate edges always meet together at just one point, a principle which enables the transmission of normal and shear forces but no bending moments between the joints, thus resulting in a bending bearing but yet deformable structure. Unlike traditional lightweight construction, which can only be applied to load optimized shapes, this new design principle can be applied to a wide range of custom geometry. The high lightweight potential of this approach is evident as the pavilion that could be built out of 6.5 mm thin sheets of plywood only, despite its considerable size. Therefore it even needed anchoring to the ground to resist wind suction loads.

Besides these constructional and organizational principles, other fundamental properties of biological structures are applied in the computational design process of the project: – Heterogeneity: The cell sizes are not constant, but adapt to local curvature and discontinuities. In the areas of small curvature the central cells are more than two meters tall, while at the edge they only reach half a meter. – Anisotropy: The pavilion is a directional structure. The cells stretch and orient themselves according to mechanical stresses.

Hierarchy: The pavilion is organized as a two-level hierarchical structure. On the first level, the finger joints of the plywood sheets are glued together to form a cell. On the second hierarchical level, a simple screw connection joins the cells together, allowing the assembling and disassembling of the pavilion. Within each hierarchical level only three plates – respectively three edges – meet exclusively at one point, therefore assuring bendable edges for both levels.

The research pavilion offered the opportunity to investigate methods of modular bionic construction using free form surfaces representing different geometric characteristics while developing two distinct spatial entities: one large interior space with a porous inner layer and a big opening, facing the public square between the University’s buildings, and a smaller interstitial space enveloped between the two layers that exhibits the constructive logic of the double layer shell.

Green Architecture

What is Green Architecture?

Environmental awareness and green architecture are the catch that suddenly seems to have flooded the media. It has become fashionable to be “green.” Through green architecture it would help us in taking good care of our planet.

Green architecture is designing with nature. It is essential component of sustainable design, applying the techniques of sustainable design to architecture that are concerned with the ecological and aesthetic harmony between structure and its surrounding’s natural and built environment. It is a practice of creating a structure that is environmentally responsible and resource-efficient throughout its life-cycle. The buildings or houses are designed to reduce the overall impact of the built environment on human health and the natural environment through efficiently using energy, water and other resources. It protects people’s health by reducing waste, pollution and environment degradation. It focuses on sustainable site development, improvement of indoor air quality, water management, energy management, solid waste management, green materials and preservation of cultural contexts.

Green architecture involves a whole-building approach to sustainability by recognizing performance in human and environmental health. This involve sustainable site selection and development, energy efficiency, water conservation, clean air, use of low-impact materials, renewable resource, and preserving indoor air quality.

Why Support Green Architecture?

Because of the urbanizations in Asia, Asian countries are increasingly looking towards Green Architecture in local conditions to preserve their resources and environments. Among these countries include Singapore, Hong Kong, China and India are practicing sustainable structures. Example of LEED approved structure in Asia is Eaton in China. Because of 31%  of furniture is reused, 34% reduction in water use, 70% percent of wood is forest stewardship council certified, 76% regional material used, 88% demolition debris recycled, 90% of seats have daylight and views and 100% carpet is recyclable, it gained LEED gold certification.

Green Architecture is not new. In Philippine setting, people has been using it through bahay kubo andbahay na bato. Phase V building in Baguio was the first LEED-certified building in the country. It earned silver certification because of its several features that enables it to operate more efficiently and with less environmental impact when compared to similar manufacturing facilities. It is oriented with respect to the sun path to minimize unwanted heat gain and maximize natural day lighting. The building is well insulated with a reflective roof to further reduce heat gain. The efficiency measures resulted in a 24 percent reduction in energy use. Extensive water reuse and recycling resulted in a 70 percent reduction in water consumption. More than 85 percent of the employees at the site ride in local or TI provided mass transportation to the facility. Another LEED approved is Clark Freeport. It earned gold certification for more than 20% of the materials in the building were made from recycled content, 40% of all construction materials were locally produced, 96% of the construction waste was diverted from landfill through reuse or recycling. More than 70 percent of the site has been preserved or restored with native plantings to minimize runoff and reduce landscape maintenance.

We need to change the way we build  because buildings are 47% responsible for the CO2 emission across the 25 nations of European union and climate change is 90% certain due to human activity, mainly through burning of fossil fuel (for energy).  Green architecture is a simplified lifestyle. Changing the actions of the people is one way of saving the planet and that includes the structures that people use. Building green structures is one way of protecting the environment. Sustainable design is meeting the needs of the present generation without impairing the ability of future generations to meet their needs. It is a way of saving the future.

Timber construction offers the possibility of minimal cost and no carbon footprint combined. Cross-wall high-rise structures, particularly residential buildings, have low stresses in their structural components. Walls and floors that are dimensioned to provide adequate acoustic separation and thermal performance have plenty of substance to resist the levels of applied loading encountered. This paper describes the design and construction of a nine storey cross-laminated timber apartment building in east central London and explores the factors limiting the height of future projects in solid timber construction. A preliminary design for a 30 storey tower is presented.

Image 03

The Stadthaus apartment building in Murray Grove was made with solid timber walls and floors using the proprietary system of KLH UK Ltd. The architects are Waugh Thistleton and the engineers are Techniker Ltd. The typical product is a panel of solid spruce formed of strips stacked in perpendicular layers and then glued under a pressure of 60 tonnes/m2. As building components these units have reduced moisture movement and increased strength compared to unmodified timbers. Manufacturing plant is arranged to provide the maximum size of panel that can be readily transported, 2.95 metres x 16.5 metres in thicknesses of up to 32 centimetres. The biggest panels therefore weigh 15 tonnes, well within the range of standard mobile craneage. The panels are usually arranged to be mutually supporting (like a card house) or in folded plate assemblies. The joints are made as simple as possible using light metal fixings to disperse forces.
