(Building) Materials from renewable resources –
great future or just a modern trend?
Are they really sustainable?

Bohumil Kasal – Fraunhofer WKI

During the last decade our environmental awareness has increased significantly and sustainability has become a frequently used term. Materials from renewable resources have become synonyms for sustainable solutions. The only truly renewable resources are plants that use photosynthesis to produce biomass. The capacity of the planet to produce biomass is not unlimited and is severely compromised by human activity. Using renewable resources to produce various materials, including building materials, does not automatically mean that these processes are sustainable or the products recyclable. This presentation will focus on global challenges with respect to the sustainability of using lignocellulosic natural resources in the production and use of materials with focus on building materials.

HOTEL MONDEGO A WOODEN BUILDING IN A MASONRY SHELL

Luís Jorge – TISEM

Luís Jorge is a structural engineer whose primary practice focuses on CLT and timber structures. He received his PhD from Coimbra University in 2008 in the field of TCC structures. He is the managing partner for the TISEM design office, where he is responsible for coordinating timber building design. He is also a Professor in the Civil Engineering Department at the Polytechnical Institute of Castelo Branco. His technical and scientific interests include timber structures and buildings and sustainability in construction. Hotel Mondego is a project developed from the renovation and amplification of an old three-story building dated to the beginning of the nineteenth century. Hotel Mondego is located in downtown Coimbra, Portugal, and has an art deco façade. The intervention consisted of complete interior demolition, preserving only the exterior masonry walls. The architectural design conceived 29 rooms, with a vertical building extension of one floor (for a total of four floors). The structure consists of a CLT solution for all the walls, floors and roof, which resulted in 280 cubic meters of wood used for the project.

TRIKÅFABRIKEN PROJECT INDUSTRIAL
CULTURAL HERITAGE RENOVATION

Matthew Eastwood – Tengbom

Matthew Eastwood holds a Masters Degree in Architecture from the University of Oregon with a focus on sustainable design, has 13 years of practice in California with sustainable architecture in light wood frame construction, and 8 years in Sweden with large-scale effi cient mass timber construction. He led the team behind the Trikåfabrikenproject. Located in Stockholm’s old industrial neighborhood Hammarby Sjöstad, the 1920s textile factory Trikåfabriken is the oldest preserved industrial property in the area. The original 1928 brick building now serves as the ground fl oor for the new edifi ce. Its subsequent add-ons (some also made during the 40’s, 60’s and the 80’s) have now been transformed into a modern and sustainable, 25,000 sqm offi ce complex. With its fi ve-story wooden frame extension, clad in Corten, it exemplifi es how contemporary architecture can link the past to the present while adding a new layer to the city. The 45-degree-angle roof has been treated as a fi fth facade and is an essential element of the experience of the building from the street and from a distance.

REFURBISHMENT AND REDENSIFICATION WOODEN SOLUTIONS

Stefan Winter – TUM

TUM façade solutions combined with additional structures (e.g., vertical extensions): This talk will look into specific rules for fire safety when adding stories to existing buildings, like those agreed to in the City of Frankfurt. These additions often lead to a building’s change of allocation to regulation-based classes and a formal increase in fire safety requirements.

15 YEARS OF WOODEN RENOVATION EXPERIENCES IN FRANCE:
TECHNICAL STUDIES, NUMERIC TOOLS AND BUILDING SITES

Frédéric Staat – FCBA Technological Institute

Frédéric Staat is a chemical engineer from Compiègne Technology University (1985) and holder of a Specialized Diploma in Business Strategies, CNAM Paris (1991). As an innovation expert, he has 35-years of leadership experience in B2B services in the cosmetics, agro and wood industries. Since 2009, he has been the FCBA Timber Industry and Construction Department Director and is currently the WoodRise Alliance Coordinator. Since 2009, numerous studies to develop wood’s use in construction, supported by French authorities and professionals, have been conducted within the framework of the so-called Wood Plans, with FCBA as the primary technological operator. Some studies were devoted to renovation with wood, such as the Rehabilitation Guide for Individual House or Developing and Renovating with Wood Project, with results integrated into numeric tools for designers, engineers and building owners. As a result, the wood market share in renovation, extension and elevation has significantly grown in the last 15 years, as shown in various illustrated implementations.

GARE MARITIME AND BRUNFAUT TOWER, TWO LARGE-SCALE
RENOVATION PROJECTS USING TIMBER IN THE HEART OF BRUSSELS

Charline Lefevre – Project engineer at NEY & Partners WOW

The “Gare Maritime”, located on the site of Tour & Taxi in Brussels, is a former railway terminal, built in the early 20th century that covers an area of 40,000 m² and reaches a maximum height of 23 m. In this magnificent historical hall that has been renovated and reinforced, the Neutelings-Riedijk Architecten’s office has inserted twelve four levels pavilions in a timber structure with a total of 45,000 m².  

Built in 1964 for social housing, the steel-framed Brunfaut Tower in Brussels will now have 1,500m³ of CLT floors and 4650m² of timber-framed facades. The renovation of Brunfaut tower demonstrates that timber is particularly adapted to meet the requirements of such rehabilitation thanks to the precision brought by 3D modelling, the prefabrication and the lightness of the timber material.

SARA KULTURHUS CENTER –
20 STORIES IN ONLY TIMBER

Robert Schmitz – White arkitekter AB

Robert Schmitz was the project architect, together with Oskar Norelius, for the Sara kulturhus, an almost 80 meters high 20-story wooden building. It houses six theater stages, the city library, two art galleries, a conference center, restaurants, and a hotel with 205 rooms in the Swedish city of Skellefteå. Sara kulturhus has been constructed from 12,200 cubic meters of wood from trees harvested from within a 60km radius of Skellefteå. The amount of carbon dioxide stored is equal to approximately 13,500 fl ights from Stockholm to New York. All of the trees used in Sara kulturhus have been replaced in the forest by young trees. In 2022 the in Sara kulturhus won the International Award for Wood Architecture, was an honoree in Global Vision Awards and won the bronze in the International Design Award for 2021.

80 M STREET SE

Jason Wright – Hickok Cole Architects

Jason Wright has over 15 years experience designing, renovating and constructing commercial and institutional buildings. His specialty is focusing on detailing and how buildings are assembled to reinforce the design concept. When not working on project design, Jason participates in the new code development process for The District of Columbia and is a member of DCBIA and AIA.
The 100,000 ft2 addition, designed by Hickok Cole and Arup, added two full floors to the existing 7-story concrete building, as well as a penthouse level with additional office and amenity spaces, including a rooftop terrace. To gain approval for 80 M’s exposed mass timber overbuild an integrated team of mass timber experts worked closely with the D.C. code authority to demonstrate that the proposed solutions fulfilled current fire and life safety code requirements and aligned with the standards of the 2021 IBC, which will allow mass timber buildings of up to 12 storeys. The project is now the first high-rise overbuild timber structure in North America.
