Successful business model renewal requires the companies to understand the changes that the new business model causes with respect to their activities, value drivers and value appropriation logic. The study employs a comparative case study strategy. Conceptualizing business models as activities, the changes that adopting an integrated solution business model to implement a real estate development causes to the business models of companies in the project delivery network, compared to their business models applied in conventional project delivery networks following a disintegrated approach, is analyzed. The findings suggest that the shift towards more integrated project delivery models causes significant changes in the alignment of value drivers and value appropriation mechanisms across the network of firms. Simultaneously, companies adhere to their existing activity content and governance. The results contradict previous studies on the organizational impact of shift towards integrated solutions. Existing research on integrated solutions and alliances has primarily focused on developing practices from the perspective of a customer-producer relationship. This study gives valuable insights related the importance of the internal logic of the service providers in achieving successful project coalition.

Global warming has brought new challenges to urban development worldwide. Built environment and cities are estimated to cause some 40-70% of the environmental impacts. This questions our current urban development practises and challenges us to find new solutions to manage the issues. The purpose of this study is to identify feasible eco-efficient concepts that can be implemented in the urban development process. These concepts are identified with a constructive research method, where potential concepts are originally identified from literature and further enhanced with thematic expert interviews, and finally, the suggested concepts are tested with a questionnaire and presented in an integrated framework for the eco-efficient concepts to better understand the requirements and opportunities in public urban development. The results showed that the urban development concepts that were most appealing to public stake holders were; an integrated design process, eco-efficient traffic and transportation solutions, and eco-efficient complementary development. Local energy procurement and management was also perceived as relatively lucrative services when developing eco-efficient urban areas. This study provides an extensive information platform (different ideas, themes, and concepts) to promote eco-efficiency in urban development in order to maintain and improve the sustainable quality of life and welfare in our urban society. Santrauka Pasaulinis atšilimas miestų plėtrai visame pasaulyje atnešė naujų iššūkių. Skaičiuojama, kad statiniai, jų aplinka ir miestai atsako už maždaug 40–70 proc. poveikio aplinkai. Tai verčia abejoti esama miestų plėtros praktika ir ragina ieškoti naujų sprendimų, kaip spręsti šias problemas. Tyrimo tikslas – nustatyti įmanomas ekologiškai veiksmingas koncepcijas, kurias galima įdiegti vykstant miestų plėtros procesui. Koncepcijos nustatomos taikant konstruktyvaus tyrimo metodą, kurio metu potencialios koncepcijos randamos literatūroje, vėliau patobulinamos atliekant teminius pokalbius su ekspertais, o paskui pasiūlytos koncepcijos patikrinamos pagal anketą ir įtraukiamos į integruotą ekologiškai efektyvių koncepcijų sistemą, kuri leidžia geriau suprasti visuomeninės miestų plėtros reikalavimus ir galimybes. Rezultatai parodė, kad suinteresuotoms visuomenės grupėms patraukliausios buvo šios miestų plėtros koncepcijos: integruotas projektavimo procesas, ekologiškai efektyvūs eismo ir transporto sprendimai, ekologiškai veiksmingas papildomų erdvių ir patalpų vystymas. Vystant ekologiškai efektyvias miesto zonas, vietinis energijos pirkimas ir valdymas taip pat laikomi gana pelningomis paslaugomis. Šiame tyrime pateikiama išsami informacijos platforma (įvairios idėjos, temos ir koncepcijos), skatinanti ekologiškai efektyvią miestų plėtrą, idant urbanizuota visuomenė palaikytų ir gerintų darnią gyvenimo kokybę bei gerovę.

Urban development bestows a great opportunity to increase sustainability in the built environment as cities are responsible for the majority of environmental impacts. However, the urban development process is fragmented and sub-optimization leads to unsustainable life cycle outcomes. The purpose of this study is to examine the urban development process from a life cycle perspective and identify how different actors understand life cycle management. By utilizing an inductive qualitative research design, 38 in-depth thematic interviews were conducted within the Finnish urban development industry including a case study and independent interviews from different phases of the urban development life cycle. The theoretical perspective is a combination of the ecosystem construct and life cycle management. Results show that there is no clear responsible actor for life cycle management in urban development. All actors claim that there is value to be added, mostly in economic, but also environmental and social terms. This study reveals that investors should be the responsible actor in the urban development process. By claiming responsibility and focusing on life cycle leadership we can improve sustainability in urban development, and respond to the urban sustainability challenge, thus improving the quality of life and welfare in our urban society.
