1 From timber to wooden houses in Sweden - status, potential and obstacles Bror Sundqvist Seminar on restorative building Pudasjärvi, Finland August 2018

2 Wood Center North Programme Director Bror Sundqvist TräCentrum Norr (TCN) Luleå University of Technology Skellefteå Campus Private Public

3 Skellefteå: Regional cooperation Triple helix for wood buildings and wood industry

4 National Board of Housing, Building and Planning Prognosis: new apartments/year until 2025

5 New production of ordinary apartment buildings with timberframe Number Percentage N.o. appartments Ratio of wooden ap. related to total production Directive for wood building Goverment offices,

6 The Government believes that increased industrial wood construction of sustainable produced forest raw materials should be promoted to increase climate benefits, housing, export and jobs across the country. (Peter Eriksson, Minister for Housing and Digital Development") Directive for wood building Goverment offices,

7 How are these future goals to be accomplished? - Some of the answers 1. Efficient and sustainable supply chain of timber and wood products 2. Capacity and succes of wooden house builders and wood element producers 3. Competence and knowledge to build in wood

8 1. Efficient and sustainable supply chain of timber and wood products Sawmill revolution X-ray scanning: Complete interior view of the log within milliseconds Marcus Wallenberg Price m/min today Kempe foundation and LTU aims to invest in latest X-ray scanner Research and innovation: Cutting parameters: Surface coatings Thinner cutting Curve sawing ok not ok customer limit Research and innovation: Automatic board scanning customised specification Multivariate control Increase timber volume yield 4% (vol) reported Increase value yield to be evaluated

9 1. Efficient and sustainable supply chain of timber and wood products Coherent wood supply chain Today ~90% traceability intake - adjustment Business driven Traceability Volume yield Value yield Digitisation Sustainability Future scenario: This wooden facade comes from my forest

10 1. Efficient and sustainable supply chain of timber and wood products LCA analysis of Swedish sawn lumber Swedish Wood(Client). Tyréns (LCA investigator) and WoodCenter North(Support) Release Sep Oct sawmills data collection 80% of CO2 footprint comes from transportation (Diesel mainly) Carbon storage within wood (negative figures CO2 footprint) Carbon release after usage (still low figures - CO2 footprint) Long lasting wood buildings (> 100 years?) mitigates global warming effects

11 2. Capacity and succes of wooden house builders and wood element producers Two market segments expanding Wood building elements Prefab volume modules C1 Cross-laminated timber (CLT), Martinson s new production line, Bygdsiljum Sweden. The new concrete Elements Company own building systems Delivery to Large contractors and builders(clt) PEAB, Skanska, NCC, JM, Veidekke etc C2 Lindbäck s wooden house module-factory, Haraholmen, Piteå Production á la car industry Modules Turnkey solutions Public and private property owners Teach us and show us how to build in wood Faster & cheaper production Flow-optimisation, digitisation Too low capacity today More knowledge: Acoustics, fire, mechanical prop., moist. Build trust and confidence Development building elements Glulam, hybrids, joints etc Innovation for better solutions Standards & regulations Renew and improve

12 2. Capacity and succes of wooden house builders and wood element producers Health and well-being Pre-study on-going (VLL Innovation): Hypothesis has wood positive effect on healing and health (hospital study), Västerbotten County Initiative by Swedish Wood and Support by WoodCenter North/Luleå Univ. Of Techn. Based on Do elements of nature have healing effect? (Nyrud et al 2017). Trondheim Hospital. Shorther nursing time? New advanced research investigation 2019? - performed and led by medical and psychiatric professors - publications in medical scientific journals During autumn 2018: Application for projects and partners What if wood reallyhas medical effect on human health??

13 3. Competence and knowledge to build in wood Equality, diversity and integration Increase attractivness of working place Find the best competence Cruical for low dense populated areas New cross-cutting knowledge needed - system wood engineers - industrial wood economists - wood architects - etc etc. A better working place for women and men at the same time

14 3. Competence and knowledge to build in wood Base knowledge of material and construction Base facts about wood rule out misconceptions - fire safety, moisture, durability Spread the news light material/elements - strong, climate smart, shorter building time, recycling benefits etc Better software construction tools with wood material/elements modules/data Better standards and regulations expert groups and R&I influences T2 College Skellefteå Campus 2017 Companies and municipalities Wood and Metal operators Laboration & Showcase 18 students starts Aug 2018 Complete acceptance for industrial wood building in 10 year?

15 3. Competence and knowledge to build in wood Public climate awarness and wood benefits Carbon dioxide slimmer Inreasing interest from private persons to mitigate climate change Example - Luleå Muncipality: Project BeChange - The beef, the car, the house ( Biffen, bilen, bostaden ) - What s my personal carbon footprint? Question: How should I build/live climate smart? Available and objective facts from wood building industry needed Strong potential for a growing wood industry Citizen Andreas Wåhlström and his climate smart family Driver for climate smart wood and building industry

16 Wood is great + Sustainable and healthy living and life style - Transport of goods and people Industry, innovation and infrastructure Sustainable cities and communities Climate action - Thank you for listening
