Strategy transformations of the Swedish sawmilling sector 1990-2005
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Prescriptive strategy theories have previously led to conclusions that sawmill firms lack strategy. However, by using Ansoff’s(1979) explorative capability approach, we contribute the finding that the Swedish sawmilling sector underwent threeunobserved strategy transformations between 1990 and 2005. These transformations, their triggers and outcomes were:Market channel strategy transformation. The shock of poor financial results in the “unexpected” downturn of the early 1990striggered a break with traditional agents, who had been the sector’s sole market channel. Instead, firms established their ownmarket channels, and built direct relationships with customers. Product value adding strategy transformation. Informationabout customers’ needs triggered a transformation in the sector’s offerings - from wet commodities to specified goods, whichwere of higher value to customers. This involved firms enhancing their production capabilities in the mid 1990s. Service valueadding strategy transformation. Triggered by perceived new SCM opportunities, firms enhanced their distribution logisticscapabilities around 2000 so that they could offer customers specific logistics and distribution services.These three strategy transformations occurred in all sampled firms. Each firm had strategy nuances, regarding its choice ofcustomers and its offerings. The findings also reveal that establishing customer relationships was a key development: product andservice value adding strategy transformations were often facilitated by cooperating with customers. Moreover, customerinteractions provided a basis for managers to increasingly see the unique value of their firm’s particular resources and capabilities;and, focus their business activities on customers who specifically value those attributes. This new interpretation of sawmill firmstrategy illustrates the need for applied researchers to assess contemporary theoretical debates, and select analytical frameworksthat can give new insights into actual practices.

Tidskriftsartikel (refereegranskat)abstract
- Energy efficiency investments have become strategically important for the European Union. In particular, energy efficient renovation and investment in the existing building stock have become major challenges. Renovation of a building should involve a holistic and integrated design process, which considers all aspects of sustainability. The aim of this work is to suggest a mathematical model that weighs economic, social and ecological aspects into a measure that supports housing owners/decision makers to find the optimal renovation alternative from their perspective, taking factors such as budget, energy consumption, etc. into consideration. Multi-criteria decision-making (MCDM) concerns structuring and solving multiple-criteria decision problems. MCDM has become popular in energy planning as it enables the decision maker to pay attention to all the criteria available and make the appropriate decision as per the priority of the criteria. In this study, the concept is introduced based on economic, social and ecological aspects assessed during a renovation project. A pedagogical example illustrates the suggested numerical system for comparing different renovation alternatives. The suggested method will facilitate decision-making processes in renovation projects and will allow decision makers to choose the best renovation alternatives that are in line with their business ideas and principles.

Forskningsöversikt (refereegranskat)abstract
- The EU has adopted several policies to improve energy efficiency. One of these policies aims to achieve energy efficient renovations in at least 3% annually of buildings in EU. The aim of this study was to provide an accurate economic comparison between three similar multi-family buildings that have undergone the same energy efficiency measures, with essential differences regarding the installed ventilation systems. The selected ventilation systems were: 1) balanced mechanical ventilation with heat recovery; 2) exhaust ventilation with air pressure control; and 3) exhaust ventilation with an exhaust air heat pump. In the latter two cases, radiators pre-heat supply air. Life cycle cost analysis were conducted using real investment and operational costs for the three buildings. Sensitivity analysis was also made for different discount rates and energy price escalation patterns. It was found that the building with exhaust ventilation has the lowest life cycle cost. At 2% inflation rate, 3% real discount rate and 1% real energy price escalation, the building with exhaust air heat pump and the building with mechanical ventilation with heat recovery has 13% and 29% higher life cycle cost than the building with exhaust ventilation, respectively. The sensitivity analysis further showed that a lower discount rate gives higher future costs and gives more profitability of systems with heat recovery with lower future costs. Energy price assumptions have a crucial impact on the results and change the profitability of studied renovation packages.

Tidskriftsartikel (refereegranskat)abstract
- Improving the energy performance of existing buildings is crucial for reaching both EU and national climate and energy targets. The main objective of this study was to map challenges that Swedish housing owners perceive when making energy-efficiency refurbishments. A secondary objective was to compare how well these challenges relate to national strategies. The study applied a combined methods approach with audience response meters and in-depth qualitative semi-structured interviews. The housing owners express the view that they have sufficient knowledge of national ambitions to improve the energy performance of buildings and welcome the new building regulations. Despite this supposed knowledge and the current economic situation with beneficial loans, the refurbishment rate still remains low. The housing owners explain that they are concerned about the ‘performance gap’ and request more accurate energy performance predictions. They are also waiting for proof that all sustainability goals can be reached in reality. Probably, too few projects fulfilling ambitions in all categories: economically, socially and energy-wise have been followed up and demonstrated nationally. The new national information centre on refurbishment of buildings may help to spread information about such projects, raise awareness and thus increase the refurbishment rate.

Beslutsstöd för upphandling av gröna byggprojekt
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Projektet ”Beslutsstöd för upphandling av gröna byggprojekt” ingår som ett delprojekt i det strategiska forskningsprogrammet Bioinnovations ”Framtidens biobaserade byggande och boende (FBBB). Delprojektet tar sin utgångspunkt i de marknadsmässiga svårigheter som trä i byggande haft i att uppfattas som ett likvärdigt alternativ till övriga stommaterial. Ett antal kommuner i landet har därför utarbetat träbyggnadsstrategier för att synliggöra trä som lämpligt stommaterial och ett material som har höga miljömässiga prestanda.Syftet med projektet har varit att belysa hur kommunala strategiska handlingsmönster kan påverka utvecklingen till att trä i byggande kommer in som ett likvärdigt byggnadsmaterial. Målet med denna rapport är att utifrån av ett antal strategier, och byggprojekt visa hur framtida upphandlingar kan se ut.Tio stycken träbyggnadsprojekt i tre kommuner med träbyggnadsstrategi har valts ut och beskrivits, via insamlad sekundärdata och intervjuer med berörda personer. Urvalet av byggprojekt grundades på att få en bredd av byggnadstyper och upphandlingsformer snarare än skillnader i kommuners handlingar och överväganden i de enskilda projekten.Sammanställningen av de tio byggprojektens genomförande visar att förekomsten av kommunala träbyggnadsstrategier har haft en positiv påverkan på introduktion och utveckling av träbyggandet. Detta tillsammans med dynamiken i den regionala/ lokala byggmarknaden. Genom att det finns en målsatt strategi skapar det en tydlighet från kommunalt håll om kommunens ambition och vilja att bygga med trä, vilket är en viktig grund för förändringen som visar sig i sammanställningen. Entreprenörerna har därmed fått incitament att lära sig träbyggande eftersom det skapar en konkurrensfördel. Den kommunala beställaren har en viktig roll i att tolka och förmedla den av politiker antagna träbyggnadsstrategin och skapa en intern förståelse och kompetens om träbyggande. Slutligen visar de enskilda projektprocesserna på vikten av ett systematiskt lärande och intern spridning av kunskap för lyckade resultat.Slutsats: Kommunerna bör beskriv och definiera långsiktiga mål med byggandet i kommunen där trä ska ingå som ett konkurrenskraftigt alternativ i beskrivningen av möjliga lösningar.

Bokkapitel (refereegranskat)abstract
- The market share of timber frame construction has increased in many European countries after the revision of national building regulations, implementation of national development programs as well as marketing efforts of the forest industry. Our research within COST E51 has looked at the timber construction industry and assessed the innovation process in eight European countries,the role and position of this industry in the construction process, and the influence of policies as drivers of knowledge creation.Results indicate that innovative timber construction firms have acted on the changed regulations overcoming the lock-in effects of construction industry standards and culture and have in some countries been in the forefront to adjust the traditional construction process. These firms have in most cases come from the forest industry sector as they have had the most to gain. The innovation type and progress differ indicating that construction is a local activity influenced by national traditions,both in industry behaviour and policy aim. It is recommended that policy makers support the establishment of local and regional timber based competence centres. Also,public construction clients ought to have bigger leeway to support innovative construction products and processes, as a mean to generating new innovations, knowledge creation and transfer necessary to create a sustainable future society.

Role of policies on innovations in timber frame construction : Cases from sub-group Timber construction vertical value chain in COST Action E51 Integrating Innovation and Development Policies for the Forest Sector
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The enlargement of EU coupled with harmonization of regulations and standards have opened new market segments and geographical areas resulting in grown market shares and innovative behaviour of timber construction firms. The role of policies aiming at increased competitiveness and innovativeness of the European forest sector through integrating innovation has been studied within a COST Action running from 2006 to 2010. COST Action E51 "Integrating Innovation and Development Policies for the Forest Sector" aimed at increasing our understanding of the role of policies and development programs to improve competitiveness and specifically innovations in the forest sector. One of the sub-groups studied the timber construction value chain and the type and diffusion of innovations. This report presents empirical data of timber construction industries from eight European countries. The data include the general construction environment and the policy superstructure of each country and one characteristic example of innovation and innovation process within the timber construction industry of each country respectively. The description of the construction industry follows the concept that construction is a complex product system (CoPS, Hobday, 1998) relating actors in an innovation system approach manner. The timber construction industry is gradually moving from supplier to system integrators thus modifying the overall system.The results indicate a large difference between studied industries in terms of type of innovation, supportive actions from society and industry organizations, and the effect of the innovation on the overall building process and infrastructure.
