TUT’s research in project ReUseSchool of Architecture,
Architectural Renovation and Redevelopment• Reuse potential in the building stock
– Location and properties of demolished buildings, demolition patterns– Location and properties of vacant residential buildings, replacement patterns
• Benchmarking of good practices– Qualitative comparison of four deconstruction/reuse cases: FIN, SWE, NLD, GER
• Architectural design from reclaimed components– Design principles for architectural design from salvaged timber, case study/simulation– Applicability of old prefabricated concrete panels for new spatial design
Department of Civil Engineering,Service Life Engineering of Structures
• Physical and administrative constraints– Damage occurring in aged concrete– Moisture and mold damage in structures– Change of norms
• Life cycle analysis– Reuse of a harbour warehouse from prefabricated concrete, carbon footprint calculation

Architectural design fromreclaimed timber
components
ReUSEFinal seminar
Introduction / timber
• Timber construction has been proposed asone solution to climate change mitigation inthe construction sector
• However, disposing / recycling morecomplicated than for steel or concrete.
• Landfill Directive will end landfilling timber by 2020.• Incineration is not recycling according to the Waste
Framework Directive.

Introduction / reuse design
• The majority of demolished buildings are timberbuildings in Finland
• Architects have been attributed with the possibility toincrease demand and supply for reclaimed timber.
• Design from reclaimed components is associatedwith high cost due to:
• Difficulty of procurement• Inconsistent quantity, quality, dimensions and incompatibility of available
products• The need for redesign rounds that follow from the above

Background / properties of reclaimedtimber• Aged timber can be superior to new timber in
– Bending Young’s modulus– Bending stregth– Compressive strength– Shrinkage
• Aged timber can be inferior to new timber in– Tensile strength– Shear stregth– Absorbed energy in impact bending– Cleavage resistance
