NEW: Study: The future of Timber Construction – CLT (Cross Laminated Timber)

This study serves to identify present and future trends relevant to the future of timber construction. If the terms naturalness, comfort and ecology are considered in the context of using materials for building future-oriented architecture, then it becomes apparent relatively quickly that this must concern the raw material wood. Wood is trending: it is renewable, can be used in many ways and makes a contribution to climate protection as part of our responsibility to the generations after us. It seeks to widen the perspective of issues already known to the industry and raise awareness of social and technological developments and trends. This study develops an exciting perspective, highlights prospective opportunities and potential. A “Must read” for everyone who wishes to be actively involved in shaping the future of the timber construction industry.

Puukuokka awarded with the Finlandia Prize for Architecture – constructed with Stora Enso CLT

The Finnish Association of Architects (SAFA) has awarded Puukuokka with the Finlandia Prize for Architecture in 2015. This eight-storey wooden building located in the city of Jyväskylä has been jointly realized by Stora Enso and Lakea. The architectural design is made by OOPEAA Architects. The award-winner was selected by the Finnish composer Kaija Saariaho.
”Puukuokka unites the aspects that I value in architecture as well as in life. Puukuokka is a bold and ambitious work including new construction technology, but it is also humane and aims toward ecological choices and improvement of quality of life,” comments Kaija Saariaho on her motivation for the selection.
”The Finlandia Prize for Architecture is a great honor for wooden construction. We are extremely proud to participate in the realization of Puukuokka and at the same time promoting modern wooden construction,” Jari Suominen, Head of Stora Enso Wood Products says.

Wooden housing is pleasant for all senses
Kaija Saariaho was pleased by the comprehensiveness of Puukuokka: ”I chose a building that pleased me intuitively and corresponds to my aims and values. Visiting the home of one resident, its coziness and outstanding acoustics confirmed this for me. Puukuokka is a building where I enjoyed myself with all my senses.” The 8-storey Puukuokka is constructed with modular CLT (Cross Laminated Timber) elements produced by Stora Enso Wood Products Hartola unit. The building includes 58 apartments that provide a pleasant living environment utilizing renewable building materials.
“Wood is the building material of the future for sustainable living,” Jari Suominen concludes.
The Finlandia Prize for Architecture was established in 2011 by SAFA, the Finnish Association of Architects. The Finlandia Prize for Architecture is awarded to a design or renovation design for an outstanding new building or building complex that has been completed within the past three years. The Prize promotes the appreciation of high-quality architecture and highlights the importance of architecture in producing cultural value and increasing well-being.

Five CLT multi-storeys rising in Trondheim, Norway

Five buildings, each nine storey high are soon to be raised with CLT in Trondheim, Norway. “Moholt 50/50 is already the third location where we are building wooden multi-storey houses for students in Norway,” says Bernd Troppmann responsible for the Norwegian market at Stora Enso Building Solutions. The first deliveries arrived Trondheim beginning July and in total 75 truckloads full of wall elements and 50 train wagons of floors and roofs resulting in 6,500 m³ of Stora Enso CLT. These five nine storey student houses will be accompanied by a library building and a kindergarten. According to the plan, it will take only three quarters of a year to finalize. Trondheim is the third Norwegian University city after Haugesund and Remmen where Stora Enso Building Solutions is providing CLT for student houses. Norway has a long tradition of building with wood.

Statement on Sustainability – CLT at Expo in Milan

“Feeding the Planet, Energy for Life” – that’s the theme of this year’s World Expo in Milan. Some 20 million visitors are expected. From 1 May to 31 October 2015, 145 nations and five international organisations will be presenting new technologies and pioneering ideas in their pavilions, each covering an area between 500 and 4,500 m² in size.

Slovenian pavilion built with Stora Enso’s CLT
Particularly eye-catching is the Slovenian pavilion with its theme “I feel sLOVEnia, Green. Active. Healthy,” which has been constructed primarily from wood and glass. The architects have combined a wood frame construction with load-bearing CLT elements produced by Stora Enso. It is no coincidence that CLT (Cross Laminated Timber) was chosen: The building material is considered a true all-rounder in the timber industry. And with its wooden pavilion Slovenia is consciously positioning itself as a country with a rich “wooden heritage.” On the one hand, Slovenia is one of the most densely wooded countries in Europe. On the other hand, wood as a material looks back on an ancient tradition here.
The world’s oldest wooden wheel, for example, was made around 5,200 years ago in Slovenia. CLT as a product, however, represents the most innovative technology in wood construction.

CLT inspires audiences at Expo 2015
The wooden pavilion, which covers an area of 800 m² was constructed by the Slovenian architectural practice “Sono Architects”. Sono Architects unites a new generation of young architects, who are committed to the construction of modern, high-quality buildings. The basis of these buildings is a mix of architectural theory, including research studies, the search for suitable locations as well as constant testing of modern materials and new construction methods. The pavilion’s pyramidal design with its geometric shapes evokes the landscape of Slovenia, where alpine mountains, Pannonian plains and Mediterranean hills combine to create fertile farmlands. This rich cultural landscape is represented by five prismatic gables.
Stora Enso’s CLT was chosen because: “It is a building material that is perfect for quick and clean constructions. The high degree of prefabrication shortens the construction period, reduces dust and noise pollution while also saving on costs,” says Herbert Jöbstl, SVP of Stora Enso Wood Products GmbH in Central Europe. Furthermore, the Expo’s theme is almost an obligation to adopt ecological values and sustainability. The country pavilions should create harmony between nature and progress as well as innovation and tradition. Slovenia’s contribution represents an intact ecosystem, in which natural resources are key for sustainable nutrition and quality of life.
In addition to the generous amount of space created inside the pavilion, there is another crucial advantage: The healthy climate in wooden buildings has been shown to have positive affects on human well-being. CLT creates a good ecological balance because wood is a renewable resource, which stores CO2 long-term. The timber used by Stora Enso in the production of CLT comes from certified sources. The pavilion’s building safety was also an important consideration and one that is fully addressed by the use of CLT elements in the construction.

The Finnish Nature Centre Haltia, constructed with Stora Enso CLT awarded in the European Museum of the Year Award 2015 ceremony

Finnish Nature Centre Haltia, built using Stora Enso’s cross-laminated timber (CLT) boards was one of the six winners in European Museum of the Year Award 2015 ceremony. It is also the first meseum awarded with Special Commendation for Sustainability. The first prize, European Museum of the Year Award 2015 went to Rijksmuseum, Amsterdam, The Netherlands. The Finnish Nature Centre Haltia was praised on the role not only of educating young people about nature, but also addressing the question of man’s capability to cope on this planet, and carries a message for the future about the possibility of long term sustainability. From its building materials to its energy-saving green technology, Haltia has been planned as an exemplar for the relationship between man and nature. The construction method and material choice are important aspects of the eco-friendliness of the nature centre. Thanks to Stora Enso’s CLT, the building is air-tight and protected against moisture, and it has good thermal and acoustic properties. Heating, cooling and lightning are also implemented with minimal energy usage. The round shape of the building, for example, diminished the heating waste in winter and the positioning of the terrace reduced cooling in the summer.

More business in Varkaus mill site

For 33 years, the hall was equipped with Paper Machine 4 (PM4) producing newsprint. Today, it is a quiet and dusty place. The echo fades away before reaching the other end of the 300 metre long building. But that will change. The premises will soon be brought back to life when Stora Enso invests in a new LVL production line creating new job opportunities for the region. Varkaus is a location where transformation is clearly visible for Stora Enso and the forestry industry. In the former PM4 building, Stora Enso Wood Product’s will start a production line for wooden building elements during the second quarter 2016. The line will produce LVL panels based on peeling technology. ”LVL is a mature and well-known technique, but Stora Enso’s innovation enables cost-efficient wooden building elements as a complement to CLT in non-visual applications. LVL will expand our product portfolio and strengthen our market position in building elements,” explains Jari Suominen, Head of Stora Enso Wood Products.

 

Beneficial location

Varkaus has been at the heart of the Finnish forest industry for decades, and was chosen for the new production line for numerous reasons. “Varkaus is an ideal location for this kind of production.  Besides utilising the available premises and the industrial infrastructure and efficient logistics, we see a clear benefit in terms of raw material availability and wood sourcing optimisation. The panel production will be using spruce and birch, partly also in sizes that we have not been able to utilise to the fullest before,” describes Mill Director Jarkko Tehomaa from Varkaus. In terms of logistics, on top of good road and rail connections the in-site harbour at Varkaus will enable efficient exports. The estimated total employment impact for the region is 150 full-time jobs, out of which approximately 80 will be directly employed by Stora Enso. “I’m very pleased to announce this investment which opens up new opportunities to Varkaus region and our employees,” says Tehomaa.

 

Building the future

In about a year from now, the empty premises of the old PM4 as well as the nearby storage and thermo-mechanical pulp plant premises will be filled with new equipment. It will not be quiet anymore. After a three-year ramp-up phase, the production line will have a yearly capacity of 100 000 m³. “The panel production line, together with the newly invested container board machine will bring Varkaus production close to the high peak years back in the ‘old days’. We will use mainly the same raw material, but the big difference is that we are producing something else. The end product is different,” Jarkko Tehomaa says. The total investment to the new wooden building element production line will be EUR 43 million. With this, Stora Enso strengthens its position as a global provider of high quality engineered wooden elements. “We believe in wood as the building material of the future. Wood is energy efficient, renewable and carbon-neutral. Engineered wood products are key in tomorrow’s wood products offering. As the population continues to grow and non-renewable raw material resources decrease, wood offers a sustainable solution to fulfil the needs of construction industry,” concludes Suominen.

 

New Varkaus integrate in figures:

Saw Mill white wood timber 260 000 m³
Pulp Mill unbleached kraft pulp 310 000 t/a *)

Australia Timber Design Awards 2014

Store Enso Wood Products received at the “Australia Timber Design Awards 2014″ for the project “Library at the Dock” two awards in the categories “Public or Commercial Building” and “Sustainability”.

Estructura hermética al aire con solo tres capas

Los elementos de madera maciza CLT de Stora Enso vuelven a convencer en términos de hermeticidad. La universidad politécnica de Graz lo ha constatado en un ensayo realizado recientemente.

Ya en el año 2008 se sometió a una prueba de hermeticidad un elemento de madera maciza CLT de Stora Enso: “Las juntas examinadas y el elemento en sí presentan una elevada estanqueidad. Debido a la elevada hermeticidad, no se encontraron flujos volumétricos mensurables a través de las dos variantes de juntas y por la superficie no interrumpida”. Actualmente la universidad politécnica de Graz ha aclarado los efectos que ejercen en la hermeticidad las grietas que pueden producirse al secarse la madera y el trabajo mecánico profundo de los elementos de CLT. De hecho, en la prueba pudo demostrarse conforme a las normas europeas en un elemento de tan solo tres capas que no se producen corrientes de aire mensurables a pesar de las grietas y procesamientos.
Todo ello confirma la enorme ventaja de los elementos de madera maciza CLT de Stora Enso, que no solo son herméticos con una estructura de 5 o más capas, sino que ya presentan esta propiedad con 3 estratos. CLT demuestra aquí claramente su primacía.

Con CLT de Stora Enso se puede construir todo el año

El uso de CLT amplía la temporada de obras y abre nuevas perspectivas en el sector de la construcción.
Es un hecho conocido que el sector de la construcción en Austria está sometido a grandes fluctuaciones estacionales, ya que el índice de empleo y el valor generado dependen directamente de la climatología. Una mano de obra en torno a 70.000 personas pasa a engrosar las cifras del paro estacional durante los meses del invierno porque los pedidos en cartera descienden en picado cuando la temporada estival toca a su fin. En los pasados años, un comienzo temprano de los rigores invernales y periodos prolongados de frío han hecho mella en la construcción, acortando aún más la época de obras.
Una forma muy valorada en la práctica de aprovechar el semestre invernal para proyectos de edificación es construir con elementos de madera maciza CLT. Stora Enso lidera este sector y suministra madera CLT proveniente de sus propias factorías también para diversos proyectos de gran prestigio internacional. CLT permite un alto grado de prefabricación y ofrece unas posibilidades casi ilimitadas en términos de filosofía constructiva, estilo y arquitectura. El tiempo de edificación en la obra se puede abreviar hasta un 40% gracias a la preproducción en las fábricas. Además, estos elementos prefabricados se pueden montar fuera de la temporada de obras tradicional. CLT es el material de construcción más prometedor porque representa para las empresas y trabajadores del sector de construcción una alternativa de futuro cuando se trata de adaptarse a los cambios de la climatología.
El potencial existente es enorme. Un sondeo realizado en el 2012 por el organismo de estudios de mercado market muestra un crecimiento continuo de la preferencia por la madera como material de construcción. El 80% de los encuestados ya tiene, de por sí, un buen concepto de este material. En el apartado de los constructores particulares se ha registrado un aumento del 10% en casas de madera desde el año 2009. También en las edificaciones municipales se observa una tendencia en pro de la madera. Especialmente en los proyectos de obras de mediana envergadura, también en zonas urbanas, el CLT despliega todas sus ventajas. Ya sea en la rehabilitación de buhardillas o para edificaciones de varias alturas en zonas urbanas: la decisión final recae cada vez con mayor frecuencia en favor del CLT. Esta buena disposición es una gran noticia para el sector de la construcción. Porque una mayor frecuencia de uso del CLT — un material para todas las estaciones — ejerce una repercusión positiva directa sobre las fluctuaciones estacionales en las cifras de paro y de negocio.

Simulación sísmica

Un edificio de tres plantas construido de CLT fue sometido a distintas simulaciones de seísmos utilizando una mesa de vibraciones. Este objeto de ensayo ha pasado sin problemas las 32 pruebas.

En febrero del 2013, en una prueba sin igual en Lisboa, se sometió a prueba la «resistencia» de una casa de edificación de muros portantes a partir de madera contralaminada, conocida por su abreviatura CLT. Una mesa de vibraciones puso a prueba en varios seísmos simulados una casa de madera maciza de tres pisos y casi ocho metros de altura. Se dedicó especial atención en las uniones de los elementos de madera, porque en un terremoto son las que más sufren. El edificio objeto del ensayo alcanzaba casi ocho metros y tenía una superficie de unos 90 metros cuadrados repartidos en tres habitaciones de tres plantas. En total se provocaron 32°seísmos. 15 de ellos superaron 0,2 g y en uno de ellos, incluso, pudo alcanzarse una aceleración puntual de 0,8 g. Después de todas las pruebas realizadas no se pudo constatar ningún daño significativo en el edificio, lo que demuestra que CLT es el material ideal especialmente en las zonas con riesgo sísmico.

Proyecto de CLT en Graz, Austria

En el mismo centro de la ciudad de Graz se están erigiendo 12 edificios de CLT con una estructura de madera y adobe y forjados vistos de CLT. Estas edificaciones de tres, cuatro y cinco alturas requieren un total de 4 400 m³ de CLT, de los que 2 000 m³ tienen calidad industrial vista. La promoción prevé 143 apartamentos, muchos de ellos con jardín o terraza. El proyecto ha obtenido la distinción de ORO del programa klima:aktiv y su concepto energético alternativo incluye el intercambio térmico con un supermercado anejo. También se ha realizado un estudio sobre movilidad con energía eléctrica.

Library at the Dock en Melbourne, Australia

El primer edificio público de CLT, la Library at the Dock, se está construyendo en Melbourne, Australia. Esta biblioteca en el barrio de Victoria Harbour destaca por su excelente valor arquitectónico y cumple todos los criterios exigibles en términos de sostenibilidad. Por todo ello se ha hecho merecedora del codiciado galardón «Five Star Green Rating» del Green Building Council of Australia. La conclusión de las obras está prevista para diciembre del 2013 y la biblioteca abrirá al público a comienzos del 2014. Esta biblioteca forma parte de un amplio proyecto de infraestructuras.
