Challenges for sustainable refurbishment and urban redevelopment in Europe are based on: the demand for renovation of existing building stock the demand for increased energy efficiency of all buildings the demand on limiting urban sprawl the demand for social sustainability TES Renovation GWG Münich, Germany.

Changing needs of different age groups like prosthetics for a disabled city? Senior citizens under-represented in design processes Urgent needs to meet requirements for accessibility - e.g. lifts to be retrofitted, facilities for assisted living and street furniture. Need for diversified housing types and improved standard of life. Research and local industry are developing new timber construction in a predominantly concrete and red-brick built environment.

Participation in design process: mapping social transformation Combining Geographical Information System (GIS) and Building Information Modelling (BIM) Background analysis: Neighbourhood SWOT GIS responses: positive / negative / ideas Synthesis: extend / infill / conserve / connect Visualize proposals for feedback
Public priorities change, and need to be clarified and (re)defined: Positive response to proposals for urban infill and refurbishment It is possible to infill housing and increase density by enhancing the quality of urban environment Infill proposal including mixed and small-scale housing typology in a modern village with intimate landscaped courtyards to diversify the supply of apartments Image source: Leeni Harno, KLIKK Master s thesis, Aalto University, 2013
A need for a new hierarchy in public spaces and intimate landscapes Residents wish for a clear identity for their built environment: pleasant courtyards, maintenance of green spaces. Public space and urban infrastructures in the neighbourhood are being loosely defined: Designers proposed a hierarchy and specific themes to enhance green spaces, and a new urban park adjacent to a rundown shopping centre.

Practical experience from research and pilot projects in refurbishment Lightweight, durable, life cycle facades possible Demolition work require care and occupational safety Detailed design, measurement and survey essential Airtightness critical : windows, penetrations, foundations Energy targets demand investment social motivation critical Need to monitor energy use and building service systems Cost effective competition in prefabrication is growing Contractors are interested in extensive retrofits www.e2rebuild.eu www.tesenergyfacade.com
