PresentationInternational conference on Life cycle Design of Buildings, Systems and Materials

12th of June 2009Berri de Jonge, MScPlegt-Vos, New Business

Introduction

• Plegt-Vos • Case Mind Building™

– context– the system– life cycle costing– state of the art– issues

Plegt-Vos

• Developing building company operating in the north, east, west and central part of The Netherlands (6 offices in The Netherlands)

• Real-estate development & Construction• 750 employees• Turnover: 220 million Euros / year

Plegt-Vos

• Focus on our environment• Focus on our customers• Develop concepts to meet our

customers needs– Flexibility– Design for disassembly– Re-use of materials

Case Mind Building™

• Idea: Jan Wind, Jan Wind Architects• Co-development: Jan Wind – Plegt-Vos

What is Mind Building?

• Different way of building;• Building for the future;• Integrated system:

Total solution for structure and technical installations;

Context Traditional Construction

Context: Traditional Construction Properties

• Static buildings – not flexible• No answers for changing requirements during the use of

the building• Demolition is necessary when the building no longer

meets the user requirements• Waste of materials

Key Properties Mind Building

• Flexible (inside and outside)• Sustainable• Design for variety• Assembly and disassembly• Minimal waste of materials

Achieved through:• Industrial production• Standard interfaces and building components

Application possibilities

• Houses

• Apartments

• Utility– Schools– Hospitals– Care centres– Office buildings

Advantages for our customer

• Less Total Cost of Ownership– Fast building process (industrial/assembly)– Less costs for change in use– Less costs for maintenance

• Building has more value and keeps value– Easier to adapt future new needs / demands– No demolition but re-use of components

How? Key Principles of the System

Combinatorial modularity(Salvador et al., 2002a)

different façade components

real façade component(masonry)

Assembly of components1) Foundation

2) Floor components

3) Exterior wall components and/or columns

4) Floor components

1) Standardized Foundation

2) Floor components

3) Exterior Wall components

4) Floor component

Technical installations and heating

• Flexible;• Separated from the structure;• Combination of floor/air heating

and ventilation;• Low temperature heating;• Free cooling possible;• Ready for the future: alternative

energy sources easy to connect.

Life-cycle costs

• LCC Research conducted: comparison between traditional building method and Mind Building;

• Conclusion:– Mind Building has more advantages

during use of the building (re-use of components);

– Eliminate start-up costs of new development as quick as possible;

State of the art

• Prototype testing (ready)(component level and system level)

• Pilot project The Hague: 60 houses

Issue

• Focus on initial costs value of sustainability and flexibility reveals in exploitation phase.
