Conservation and maintenance of modern buildings. The need of long-term maintenance of building fa\ue7ades in metropolitan housing areas. A model-proposal for documentation, analysis and intervention.

ABSTRACTMany European towns, as well as conurbations world wide include a significant amount of residential prefabricated buildings from the late 1950s, 60s and 70s. Housing often is concentrated to suburbs as a result of societal planning and development during this period. However, examples of prefabricated residential structures from these years in districts close to town centres are also occurring. In G\uf6teborg the huge amount of multi-apartment blocks from the 1950s through mid-70s today are moving into focus of the responsible property managers partly due to an increase of major needs of maintenance and partly due to the substantial economic assets that these structures represent. National and international preservation bodies, non governmental organisations, and academia concerned recently have started processes to address and observe technical, material and structural aspects of industrialised suburban housing, as well as values and fundamental perspectives related to this kind of buildings and their built environment.In order to enhance knowledge about the material and technical aspects, as basis for identification of appropriate long-term techniques for maintenance, it is crucial to work out problem-driven methods for monitoring, documentation and analysis of occurring building-materials and related issues of their deterioration. Hence, this complex situation strongly indicates a need of holistic perspective for the design of a relevant instrumental approach for documentation purposes and the subsequent need for analysis.This thesis presents a tentative model for documentation and analysis based on photogrammetry and in-situ light microscopy, in combination with methods for laboratory analysis such as scanning electron microscopy and X-ray diffraction. This approach is argued to enable a needed overview of fa\ue7ades of multi-apartment buildings, their constituting materials, and related deterioration phenomena

Documentation and Maintenance Planning Model – DoMaP A response to the need for conservation and long-term maintenance of fa\ue7ades of modern multi-apartment buildings Based on case studies in G\uf6teborg in Sweden

Sustainable maintenance and renovation of fa\ue7ades on generic multi-apartment buildings from late 1950s through 70s constitute vital challenges for the housing companies owned by City of G\uf6teborg. These challenges comprise a wide array of issues, such as deterioration and damages in occurring fa\ue7ade materials, status assessments, technical improvements, reduction of energy consumption, and up-keeping of housing qualities and tenants attraction. Thus, new approaches to data-acquisition are called for. The presented Documentation and Maintenance Planning model (DoMaP) is a proposal for a new approach to acquisition of various types of data from fa\ue7ades of modern generic multi-apartment buildings. The DoMaP model aims at substantial contribution to stringent status assessment of fa\ue7ades, and thus, to enable long-term maintenance planning, providing adequate conditions for integrated sustainable conservation. The DoMaP model is based mainly on optical techniques (i.e. metric as well as non-metric). Techniques for air pollution monitoring, and for material analysis are included in the DoMaP configuration. The benefits of this new comprehensive approach to data-acquisition may be summarised in provisions for increase both of efficiency (i.e. resource utilisation) and effectiveness (i.e. productivity and quality) of fa\ue7ade-maintenance operations, thus also contributing to sustain technical service-life and functions of residential structures. Finally, it is important to stress that information provided by the DoMaP-approach would be of relevance to identify characteristics of built environments, and thus contributing to any process of valorisation of built environments

Effektiv visualisering av byggnadsdata - ett st\uf6d f\uf6r h\ue5llbar renovering av byggd milj\uf6

Vi kan konstatera att ett n\ue4tverk har etablerats (se bilaga 1 – N\ue4tverkets deltagare). Deltagarnas reflektioner och gruppernas projektid\ue9er pekar dessutom p\ue5 ett genuint intresse att g\ue5 vidare i processen mot konkret samverkan. Reflektioner och projektid\ue9er speglar materialet fr\ue5n workshopen (gruppredovisningar, individuella redovisningar i arbetsboken, och bl\ue4dderblocksanteckningar).Grupp 1 betonar bland annat vikten av \uf6ppna dataformat och tydliga krav fr\ue5n fastighetsf\uf6rvaltare som ett viktigt st\uf6d i utveckling av relevanta modeller som kan generera bra visualiseringar.Grupp 2 har en delvis liknande ansats n\ue4r man po\ue4ngterar att den enskilde f\uf6rvaltaren och byggnaden utg\uf6r viktiga resurser n\ue4r m\ue5let \ue4r anv\ue4ndarv\ue4nliga metoder och tekniker f\uf6r dokumentation, visualisering, och simulering av olika scenarier.Grupp 3 har kanske det mest konkreta f\uf6rslaget. H\ue4r betonas hur viktigt det \ue4r att kunna f\uf6lja och visualisera energifl\uf6den f\uf6r att genom justerande \ue5tg\ue4rder kunna bidra till minskade kostnader.I grupp 4 s\ue4tter man in visualisering i ett st\uf6rre sammanhang. Visualisering relateras till stadsutveckling, demokrati, och beslutsprocesser.F\uf6r att kunna identifiera n\ue4sta steg i processen, som f\uf6rhoppningsvis leder till ett konkret projekt, kan det vara bra att ta st\ue4llning till om fokus skall vara p\ue5 en enstaka projektid\ue9, eller om olika id\ue9er kan integreras framg\ue5ngsrikt i ett st\uf6rre \uf6vergripande projekt.Projektid\ue9n ”Visualisering – vart tar energin v\ue4gen?” \ue4r en bra utg\ue5ngspunkt som kan relateras till reflektioner och id\ue9er som identifierats i de \uf6vriga projekten. Ett n\ue4sta steg kan vara ett mindre samverkansprojekt som resulterar i en skiss till en ”pilot” eller ”demonstrator”.M\ue5let med en s\ue5dan ”pilot” eller ”demonstrator” \ue4r att visa p\ue5 n\ue5gra konkreta applikationer som har potential att fungera i ett framtida skarpt l\ue4ge. Om denna ”pilot” faller v\ue4l ut \ue4r det rimligt att t\ue4nka sig ett st\uf6rre gemensamt samverkansprojekt som l\uf6per \uf6ver en l\ue4ngre period. Den \uf6vergripande m\ue5ls\ue4ttningen \ue4r d\ue5 att bidra till \uf6kad nytta f\uf6r involverade f\uf6retag genom samverkan mellan forskare och praktiker

Conservation and sustainable maintenance of modern urban architecture: the need for problem-driven methods for documentation and analysis of deterioration phenomena in building envelopes

European cities include a significant amount residential prefabricated buildings from the post-WW2 period. In G\uf6teborg, Sweden, the huge amount of recent multi-dwelling blocks are today moving into focus of property managers due to immense needs of technical maintenance and the social and economic asset these housing areas represent. Referring to the perspectives of Integrated Conservation and Sustainable Urban development, as well as to the preliminary results from a current case study in G\uf6teborg, and related research, this paper presents a model in progress aiming at holistic maintenance planning and development of long-term intervention techniques. It is argued that problem driven innovative methods for technical documentation and analysis of building envelopes, and related issues of material deterioration are fundamental for long-term maintenance

Strategies for an Integrated Sustainable Renovation Process: Focus on the Swedish Housing stock ‘People’s Home’

This study focuses on elaboration of scenario parameters to support strategies for an integrated renovation process of culturally valuable pre-boom housing stock from the People’s Home(Folkhemmet) period i.e. 1945-1960 in Sweden. This stock, now in focus for renovations, combinesolder craftsmanship with thorough planning on a neighborhood level. Their qualities refer to aesthetics, material use, living qualities and efficient use of space. Present renovation strategies often reduce the complexity of the problem to technological and energy saving measures in a short-term perspective. Integrated and differentiated strategies are needed in order to improve energy efficiency and environmental performance, whilst respecting and safeguarding potential loss of invaluable cultural, architectural and social values (immaterial values). This paper presents a model to identify and describe both material and immaterial parameters which need to be known,valued and balanced in integrated sustainable renovation of the People’s Home housing stock. The model covers ten areas: (a) general description, (b) architectural quality, (c) social quality, (d)cultural quality, (e) technical description, (f) technical performance, (g) functional performance, (h)environmental performance, (i) economic performance, and (j) renovation process quality. A specialattention is given to our exploration to define and describe immaterial values such as architectural, cultural and social qualities
