DESIGNING QUALITY WITH A SUSTAINABLE PROCESS
Ingrid Svetoft
Abstract: With the necessity to build a sustainable society the process and the interaction between the actors involved must also be sustainable. With a long-term perspective the ambition is to produce a building with sustainability, energy efficiency and good quality. The users’ requirements and the factors for life quality should also be translated and transferred into the building process. To solve the issue of securing life quality into the end-product, the actors involved need to work together with a joint ambition.
How can the actors involved communicate and collaborate in a better way to achieve a good product? Methods and models for planning and performing sometime seem to forget that there are people involved. Each person with different driving forces connected to different awards. The collaborative way of working can give the consultant team the right spirit and their knowledge can better be used in a safe atmosphere. The building process can be both joyful and satisfying if you can use your skills and competence. There is however both obstacles and possibilities for the architects and the other actors involved when working in this kind of process.
The architect can be an important actor who handles the complex process and transferring of the end-users needs into the building process. The Swedish Association of Architects declares in their political program in February 2008 that architecture can be more useful for the society and the sustainable development. Architectural knowledge can maintain the holistic view during the process and add both social and human values. The tools and preparations for this role must be given during the architectural education. Does the architectural education support the role of handling a sustainable process and a sustainable product? In the design process both design models and quality tools could be used to support the architects’ role and also support a better learning from experiences made in other projects. Better knowledge and understanding of building materials, technology, energy systems and economy could also be useful.
The objective of this paper is the question of how the actors involved can achieve better and results if the right orders and resources are given by the Construction Client. A short discussion about how the architectural education in Sweden supports the architects to take a leading role in the development of a sustainable society will also be a part of this paper.
The method of performance of this research contains literature reviews and a summary from performed questionnaires and interviews. The result is an overview of how different factors can support a better communication and collaboration between the actors involved in a sustainable building process. The contribution of this research is a proposal of how architectural knowledge and collaborative work can be used designing a sustainable built environment.

THE ROLE OF FACILITIES MANAGEMENT IN BUILDING PROJECTS
Per Jensen, Torben Damgaard, Kristian Kristiansen
Abstract: One of the problems in the building industry is a limited degree of learning from experiences of use and operation of existing buildings, when new building projects are planned. Can the development of professional Facilities Management (FM) be the missing link to bridge the gap between building operation and building design and what role can facilities managers play in this context?
This is one of the research themes in the new Centre for Facilities Management – Realdania Research in Denmark, which is investigated in two ongoing research projects. One project investigates the theme in relation to building projects in general based on a knowledge management approach. In a first phase a number of barriers have been identified and a range of possible ways to overcome the barriers in a short and long term perspective have been identified. The project continues with action research by following the planning process of a new university building combined with a best practice process including an expert panel, which suggests focus areas in relation to building operation for the action research in the building project and evaluates the design documents in relation to FM. The other project investigate Public-Private Partnerships (PPP) with the focus on the possible effects that the inclusion of public building projects in a PPP contract may have in relation to FM.
Based on literature overview and preliminary results from the ongoing research projects the paper will discuss the role of facilities managers and FM knowledge in relation to building projects and propose possible improvements to the learning circle from experience of use and operation of existing building to the planning of new building projects.

ARE OUR BUILDINGS “FIT” TO RESIST INCOMMENSURABLE EVOLUTION?
Peter Schwehr, Natalie Plagaro Cowee
Abstract: If 'change is the only constant' (Heraclitus of Ephesus), adaptation is a matter of survival.
Building in a sustainable way is an actual request. Flexibility is a must for any project willing to attain a long life cycle and therefore to attain sustainability. In the same way doctors care not only for a patient’s long life, but also for its high quality, a building should guarantee a high quality comfort for its users during its life period. There is a constant change of requirements due to new society patterns. In which way can a building adapt itself to the changing environment? To predict precise future needs is an exercise of speculation; the most reliable solution is to enhance flexibility in the building system which will be able to fulfil future unexpected requirements. When the world changes, buildings should change with it.
Typological exploration
The relevant factors for Flexibility remain in close interaction and are of great importance at different time periods during the planning, operation and maintenance of a building. It seems to be necessary to elaborate a basic overview about the complexity of this subject. Our project includes introductory concepts, description of different forms of flexibility, its influencing factors and their interaction.
After having made an exploration through the relevant factors which interact with Flexibility (specialisation, sustainability, metropolis, professionals), we have focused on an evaluation of Flexibility based on typologies, allowing a systematic research of the different types of Flexibility which can be generated in a building (through addition, change, use and planning). The actual demand for sustainability makes it important to integrate measures for Flexibility in early phases of design. The judgment for the appropriateness of measures to achieve Flexibility remains a great challenge during the planning process, changing classical planning models. In order to enhance Flexibility, our project includes the explanation of practical measures which can be implemented in a collaborative way, under consideration of disciplines involved in a building design (structure, façade, mechanical engineering and fire protection). To support the identification of Flexibility in a building, we have identified the key determinants which make a building flexible in a higher or lower degree (cost, time and effort) and we have sketched up diagrams which can allow investors, architects and clients to compare the degree and types of Flexibility in different buildings.

CYCLICAL SYSTEM MODEL - THE CONTEXT OF CONTRACTING AND MODULAR SYSTEMS
Jörg Lamster
Abstract: Profound ecological, economical and social changes have caused a massive refurbishment backlog of the European asset property. To face the future demands, buildings are to prove their adaptability and are to be revalued immediately. That has to take place with a minimized effort of resources and technological solutions. Therefore solutions are to be gained in line with optimized processes and organisations.
With the mentioned background, the following paper initiates the ‘Cyclical System Model’. It regards building structures, life cycles and building processes as a whole. A new hierarchy of structural elements made up of subsystems, systems, macrosystems so as the building as the total system is specified. New modular systems have simple and clear boundaries to adjoining systems. They can be mounted or dismounted easily. In this way, the level of prefabrication will increase and the level of mounting will decrease – ideal conditions for cyclical harmonized services and a competitive renovation of buildings.
It is shown that Contracting, invented by energy suppliers, is the adequate process management of the ‘Cyclical System Model’. The Contractor as the performer renders services like financial investments, constructions, mountings so as running of components and modules of the building structure. For clients Contracting is an outsourcing model. Financial investments, risks and responsibilities can be delegated. Processes of planning, building and servicing can be made more efficient and calculable. Beyond that, it is shown that Contracting implicates two further essential improvements: the functional tender to enable an immediate completion of clients’ requests (= quality) and the cyclical consideration of all processes and structures of a building.
This new alliance of partners may guarantee a minimized effort of resources (finance, raw materials, man power) for an optimized output: highly flexible building structures that match the complex life cycle demands and that can be driven and serviced efficiently and economically.
In the paper the basic idea of the ‘Cyclical System Model’ is declared with several examples of modular systems, their life cycles and implemented processes. In this way, the context of Contracting and modular construction is exemplified. Different Contracting models are introduced and compared with conventional models (organisation, life cycle costs, processes). The analogies of Contracting and Private Finance Initiative is disclosed. The future impact of the ‘Cyclical Systems Model’ is outlined.
