Decision making on indoor climate control in historic buildings : knowledge, uncertainty and the science-practice gap
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Balancing use, preservation and energy use is a fundamental challenge for the whole heritage field. This is put to the point in designing and operating systems for indoor climate control in historic buildings, where competing objectives such as preservation, comfort, accessibility, energy use and cost have to be negotiated in the individual case. The overarching aim of this thesis is to explore the gap between research and practice regarding energy efficient indoor climate control in historic buildings. The thesis deals with historic buildings where both the building fabric and the movable collection are vulnerable and where the management of the building is more or less professionalized. Examples of such buildings are palaces, churches and historic house museums, ranging from the large and complex to the small and simple. A key to a more sustainable management of these buildings is to understand how scientific knowledge related to indoor climate control can become usable for the professional practitioner. The thesis comprises six published papers introduced by a thesis essay. The papers reflect a progression both in terms of the research questions and the methodology. The first three papers outline the background needed for a technical understanding of the involved matters through an identification of key knowledge gaps. The three remaining papers use qualitative case studies to understand the nature of the gap between science and practice by paying more attention to the social aspects of decisions related to indoor climate control. Generally, the results of the thesis contribute to an expanded problem definition and to a better understanding of the gap between research and practice regarding energy efficient indoor climate control in historic buildings. It is shown how the specific social and material context is crucial for enabling or limiting a transition toward more sustainable ways of controlling the indoor climate. Furthermore it is discussed how uncertainty can be managed and communicated to support decisions, and suggestions are given for how decision processes regarding indoor climate control can be supported with improved standards to facilitate a more sustainable management. A conclusion for further research is that scientific knowledge alone will not be able to guide the transition to a sustainable, low carbon future; technical esearch has to be complemented with reflexive research approaches that explore the actual practices of heritage management.

Conservation of the wood of the Swedish warship Vasa of A.D. 1628. Evaluation of polyethylene glycol conservation programmes
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The principal aim of this dissertation is to investigate whether or not polyethylene glycol (PEG) has acted as a dimension stabilizing agent of the Vasa wooden material, i.e. whether or not the PEG molecules have penetrated into the secondary cell wall, and in this have been enabled to preserve the capillary system through the drying and continuing maintenance periods. This dissertation deals with the experimental work made at the Vasa conservation laboratory parallel to the conservation performance, with the aim to gain reasonable knowledge about the conservation parameters to proceed with the treatment, and to adjust the methods to needs observed. The experimental work was mainly performed as immersion treatments and with oak wood material removed from the Vasa hull as test material. The results were used at the surface application on the Vasa hull as well as at the immersion treatment of large loose timbers and wooden objects from the Vasa. The achievement of an equilibrium between the PEG-concentration of the conservation solution and the PEG absorbed by the wood involved was agreed upon as a basis for the conservation procedure, but it soon became obvious that the equilibrium criteria were difficult to define. The main conclusion of this dissertation is that the PEG’s 4000, 1500 and 600 have acted as dimension stabilizing agents of the Vasa oak wood by an anti-shrink-efficiency (ASE) factor of 60% and higher, with amounts of 30% PEG and higher in the dry matter of the Vasa oak wood-PEG 4000, 1500 and 600 composites respectively.

Byggnaden som kunskapskälla : The building as a source of knowledge
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Buildings are indeed mute, yet many historians and architects claim that they can nevertheless speak. The challenge is to understand their language. This thesis examines the building as a source of knowledge. Setting out from a repertoire of historical investigation methods used by professional actors within the field of architectural conservation, the thesis deals with the question of what standard buildings can teach us about the past. What can buildings say, and to whom? The thesis is based on a case study of the national cultural reserve of Örnanäs in the region of Skåne in the south of Sweden. Örnanäs serves as a laboratory for action-based research and involves both conservationists and craftsmen. The unit of analysis is not the site in itself but the context and process of investigation. The process is examined from three perspectives, which correspond to the layout of the thesis: the forensic perspective on material culture, the source pluralism perspective, which refers to the possibility of combining information from multiple sources, and the actor perspective, which sheds light on how the actors involved influence the investigation. A theoretical platform is given by Carlo Ginzburg’s perspectives on diagnosis through clues and Martin Weaver’s approach in ‘forensic conservation’. The results constitute a set of reflections and judgements on a range of different survey methods and sources. In focus are working methods that facilitate an increased exchange between practice-based research and research-based practice. The forensic perspective activates the building as a source of knowledge, and by combining different approaches it is possible to shed light on the history of the building from many different angles. Inquiry of historic construction, material use and signs of toolmarks, tested through processual reconstruction, is a method that has been systematically examined. The conclusion is that this method requires craft skills, yet it also opens up for cross-disciplinary work and thinking. The results articulate the importance of a heuristic approach. As conservationists and architectural historians we need to oscillate back and forth between the details and the whole, between observations and logical reasoning and between a physio-technical and socio-cultural perspective in order to uncover the layers and traces of the history of a building. Keywords: Architectural conservation, historic buildings, building survey, survey methods, historical sources, building documentation, mapping, architectural drawing, architectural analysis, forensic conservation, reconstruction, historical work process, traditional building craft.

Craft Sciences
- 2022
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- The field of ‘Craft Sciences’ refers to research conducted across and within different craft subjects and academic contexts. This anthology aims to expose the breadth of topics, source material, methods, perspectives, and results that reside in this field, and to explore what unites the research in such diverse contexts as, for example, the arts, conserva-tion, or vocational craft education. The common thread between each of the chapters in the present book is the augmented attention given to methods—the craft research methods—and to the relationship between the field of inquiry and the field of practice. A common feature is that practice plays an instrumental role in the research found within the chapters, and that the researchers in this publication are also practitioners. The aut-hors are researchers but they are also potters, waiters, carpenters, gardeners, textile artists, boat builders, smiths, building conservators, painting restorers, furniture designers, il-lustrators, and media designers. The researchers contribute from different research fields, like craft education, meal sciences, and conservation crafts, and from particular craft subjects, like boat-building and weaving. The main contribution of this book is that it collects together a number of related case studies and presents a reflection on concepts, perspectives, and methods in the general fields of craft research from the point of view of craft practitioners. It adds to the existing academic discussion of crafts through its wider acknowledgement of craftsmanship and extends its borders and its discourse outside the arts and crafts context. This book provides a platform from which to develop context-appropriate research strategies and to associate with the Craft Sciences beyond the bor-ders of faculties and disciplines.

Leaving dry land: Water, heritage and imaginary agency
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This doctoral dissertation explores the interplay between water, heritage and the agency of the imagination. Instead of seeking how to map subjects or heritage, the research focuses on the ways in which mapping and the cartographic gaze have produced subjects in specific categories. It seeks to create moments of orientation and reorientation to experience the effects, affects and possibilities to imagine ways beyond these fixed geocodes and the taken for granted. As such, this dissertation contributes to broader discussions regarding critical design practices alongside critical heritage studies, while channelling design’s ability to shape the world and to explore potential approaches that foster collective imagination and planetary care. Two iterations of a fluid methodology were conducted in Mexico City and Gothenburg, foregrounding precarious issues in heritagisation processes and exploring aquatic agency. The methodology provides a tool for bridging different epistemologies, disciplines and perspectives, fostering transdisciplinary collaboration and knowledge permeation. By engaging with water as a subject and employing imaginative techniques, the research aims to actively (re)imagine the past, present and future of urban environments, enabling diverse infrastructures, ecologies and cosmologies to emerge. Heritage is reconceptualised as a navigational system that traces diverse relations in the world. In this sense, the research challenges modern heritage paradigms by acknowledging the ephemerality of water.

Kalkbruk-krympsprickor och historisk utveckling av material, metoder och förhållningsätt
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- I denna avhandling undersöks uppkomst av krympsprickor i puts. I undersökningen används våtsläckt sub- hydrauliska kalk. Den aktuella kalksorten har används i Sverige under 1800- och 1900-talet men också under 2000-talet i samband med putsrestaureringar. Observationer i samband med framställning och användning av denna typ av kalk pekade på att om kalken bearbetas för att den skall vara lättare att sila och förpacka samt därefter lagras uppstod en högre frekvens krympsprickor i putsen än om kalken inte lagrades eller upparbetades. En undersökning gjordes för att undersöka det empiriskt observerade sambandet. Resultaten från undersökningen visade att upparbetning och lagring av våtsläckt sub-hydraulisk kalk bidrog till att frekvensen krympsprickor i puts ökade. Resultaten pekade på att bindemedelrika bruk kunde var möjliga att framställa och använda i praktiken. En förutsättning för framställning av bindemedelrika bruk var att bruket blandades på nysläckt kalk. Detta sätt att tillverka bruk på ökar risken för att skador av osläckt kalk uppstår. För att minska denna risk rekommenderas under 1900-talets mitt att våtsläckt kalk skall lagras från 1-4 veckor innan den används. I motsats rekommenderas under 1800-talet att bruk framställs på nysläckt kalk med motiveringen att det ger bruket bättre beständighet. För att undersöka användbarheten av nysläckt kalk i praktiken implementerades resultat i en putsrestaurering av en medeltida kyrka. Syftet med implementeringen var att undersöka om bindemedelrika bruk gick att framställa på nysläckt kalk utan att oacceptabla krympsprickor eller kalkskott uppstår. Resultat från den implementerade studien visade att bindemedelrika bruk var möjliga att framställa och använda utan att oacceptabla krympsprikor eller kalkskott uppstod.

Balancing Building Conservation with Energy Conservation - Towards differentiated energy renovation strategies in historic building stocks
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Balancing building conservation with energy conservation is challenging. The overall aim of this thesis is to bridge the perceived conflict of reaching climate and energy goals on the one hand and the goals of a sustainable management of historic building stocks on the other hand. Historic buildings constitute an important representation of the built heritage, and make up a large part of the total building stock. Within the historic building stock, there are opportunities for energy efficiency improvements that can, and should, be undertaken in order to contribute to climate and energy goals. However, changes due to energy improvement measures need to be made without damaging or destroying the heritage values that are embodied in, and represented by, historic buildings. For this to happen, heritage values need to be identified, acknowledged and articulated in a systematic and transparent manner in order to be balanced with other interests when assessing energy saving potential in relation to building conservation requirements. Three areas are of importance to move the issue of balancing building conservation with energy conservation from building level to building stock level. These are 1) adapted decision support processes for historic building stocks, 2) methods to integrate aspects of heritage values for decision support processes, and 3) building stock analysis aiming at developing differentiated energy renovation strategies for historic building stocks. Decision-support processes have been developed and tested for buildings and building stocks. On building level, the proposed process allows for interaction between a quantitative assessment of the techno-economic optimisation and a qualitative assessment of vulnerability and risks. On building stock level, categorisation to produce archetype buildings, restrictions with regard to heritage values and extrapolation of results from the optimisation are added to the process. The building stock analysis visualises the relationship between different segments of a selected historic building stock and thereby shows the need for differentiated energy renovation goals and strategies that reflect the diversity of the building stocks. The results provide not only a method to develop differentiated energy renovation strategies, but also argue for the need for coherent and coordinated information about the historic building stock. As a conclusion, my thesis has shown how to support informed decisions that balance energy conservation with building conservation for both individual buildings and building stocks. Further development is needed towards standardised decision support processes for historic building stocks that include the trade-off between preservation of heritage values and energy efficiency.
