Ecovillages acting as experimental community models have the potential to help move society towards sustainability by developing alternative solutions for sustainable living. Their contribution is through the power of example, demonstrating successful alternative systems that can be replicated at higher scales through the broader community. However, ecovillages often struggle with long-term planning and lack a systematic approach to integrating structure, processes and actions into strategic planning. Research was conducted to examine how ecovillages could be supported in this deficiency to make them more successful as models of sustainability. An initial document review of tools and concepts currently used in the ecovillage movement uncovered a recently developed concept called the Wheel of Sustainability (WoS). The Framework for Strategic Sustainable Development (FSSD) was applied to analyse this concept and to inform the development of a new prototype tool. The research was conducted in collaboration with experts in the ecovillage field and FSSD practitioners, through interviews and a final validation survey. The result of the research led to the co-creation of an enhanced communication and strategic planning tool, the Direction Indicator for Sustainable Communities (DISC), intended for use by ecovillage communities. Further research is recommended to field-test and further refine this tool.

Syftet med denna studie är att försöka utreda vilken roll arkitektoniska icke-människor spelar för skapandet av socialt samspel i en ekoby. För att utreda detta utgår studien från ett antal posthumanistiska teoribildningar, främst actor-network theory och begreppet materielldiskursiv. Dessa teoribildningar anser att även icke-människor, så som hus och brevlådor, ska ses som medskapare till världen men att deras agens bestäms av vilka andra aktörer de kopplar ihop sig med i nätverk. Genom observationer och intervjuer med sju boende i en ekoby har material insamlats om det sociala samspelet i ekobyn. Empirin vittnar om att många olika icke-människor spelar en roll för skapandet av det sociala samspelet som uppstår där. Det handlar bland annat om att gemensamhetshus ger plats för gemensamma aktiviteter, att öppna gräsytor möjliggör lek och att brevlådor uppmanar till rörelse. I sig själv skapar dock inte de arkitektoniska icke-människorna socialt samspel. För att de ska få den betydelsen behöver de användas och tolkas av andra aktörer. Svaret på frågeställningen blir följaktligen att de arkitektoniska icke-människorna spelar en roll för att socialt samspel uppstår i ekobyn men vilken roll de spelar är beroende av vilka andra aktörer som de kopplar ihop sig med. / The purpose of this study is to try to investigate the role that architectural non-humans play for the creation of social interaction in an eco-village. In doing this, the study uses a number of post-humanist theories. Mainly actor-network theory and the material-discursive concept. These state that even non-humans, like houses or mailboxes, are to be seen as co-creators of actions, but that their possible roles are decided by which other actors they attach to in a network. Through observations and interviews with seven residents of an eco-village, the information was gathered. The empirical data shows that many different non-humans are taking an active role in the creating of the social interactions that goes on in the eco-village. To mention a few, the community hall gives room for group activities, open lawns create a possibility for child’s play and mailboxes call for physical movement. In themselves, however, the nonhuman actors do not create social interaction. It is only when used by and interpreted by other actors that they gain their active role. The answer to the question would consequently be that the architectural non-humans in the eco-village do play an active role in the creation of social interaction but that the role is dependent on the other actors that they connect to.

This thesis presents a general description of approaches to energy efficient building development under Chinese contexts. The purpose of the work is to discuss how Chinese building development can be approved from an energy saving perspective. Building development is a complicated process that relates to many stakeholders’ interests. The developed countries have studied in this field extensively for several decades. Generally, the approaches to energy saving can be set at three levels: administration, construction industry and architectural design.

Various technical solutions for energy efficiency are developed as well. The administrative approaches are not the main objective discussed in the thesis, though the importance of them is undeniable. BEA systems are not only assessment methods, but also market-based stimulating approaches for sustainability of construction market. Technical methods have been developed for a long period. Passive House and Low Exergy (LowEx) Systems are two representative examples in European countries. All of these approaches are relatively unfamiliar to Chinese architects and developers, let alone their effect and applicability. The thesis tries to analyse this situation and their applicability within Chinese context. In China to a certain project, the importance of technical issues is relatively recognized.

Over the years, every major city turns into a knot of intractable problems: overpopulation, traffic jams, environmental degradation. Some countries make a faster conversion from an industrial development to an information growth phase, than the infrastructural changes take place. Therefore, environmental design and construction would not be short-termed, but rather will be the long-term targets for all the groups associated with the construction. The healthy living is one of the most important reasons to start a complicated long-term reconstruction of eco-cities. Successful ecological reconstitution requires a knowledge about already implemented exemplary solutions. For this purpose, the dissertation analyzes the basic ecological problems of settlements, analyzing the examples of approaches to improve the environmental performance of cities on the reference of foreign experience and creates criteria and principles for designing urban structures for healthy living in CR.
