- This article presents and discusses the challenges of refurbishing historic apartment buildings by correlating findings from research projects LEAF and CulClim. Our aim is to shed light on how residents can partake in and optimise the refurbishment process after energy performance certificates (EPC) have been conducted. The background is that historic apartment buildings are generally more complex than single family buildings with respect to the energy efficiency process as they often have multiple owners with different priorities. The case studies from Norway and Sweden have conceptually contrasting energy performance certificate (EPC) systems. Identified advantages and shortcomings concerning both systems are discussed. In Sweden, the restrained recommendation of measures can lead to national mitigation targets not being realised. In Norway, excessive and unqualified recommendations risk reducing the cultural heritage values of the existing building stock as well as having a negative environmental impact on greenhouse gas emissions. A bottom-up approach incorporating the resident's objectives is presented and discussed. Results suggest that improved EPC-systems and a broadened procedural approach to decision making will ease the process and improve the outcome of the refurbishment with respect to both energy and heritage aspects.

- Tor Broström is a Professor in Conservation at Uppsala University, Campus Gotland, Sweden. With a background in engineering, his research focuses on indoor climate and energy conservation in historic buildings. He is coordinator of the Swedish national research programme on energy efficiency in historic buildings. Petra Eriksson, is a lecturer and PhD candidate in conservation at Uppsala University, Campus Gotland, Sweden. Petra has a background in the applied field of conservation and her research is in the field of heritage conservation in relation to energy efficiency. Linn Liu is a PhD candidate in the Division of Energy Systems, Department of Management and Engineering at Linköping University, Sweden. Her research area is within energy efficiency and cost efficiency of multifamily buildings and historic buildings. Patrik Rohdin is Associate Professor in the Division of Energy Systems, Department of Management and Engineering at Linköping University, Sweden. Patrik is conducting research related to energy efficiency in the built environment and building simulation and is active within the national interdisciplinary research programme, program energy systems. Bahram Moshfegh is a Professor and Head of the Division of Energy Systems, Department of Management and Engineering at Linköping University, Sweden. Professor Moshfegh has been active in the following research areas: mathematical modelling and measuring techniques for air and energy flow in buildings, energy-efficient HVAC systems and local and regional energy systems. Fredrik Ståhl is Senior Researcher in the Department of Energy Technology at SP Swedish Technical Research Institute. Currently, his research is focused on energy efficiency in historic buildings. The Swedish research project 'Potential and Policies for Energy Efficiency in Swedish Historic Buildings' aims to investigate the interdependency between political energy targets and effects on the built heritage. The fi rst part of this paper presents an iterative and interactive method to assess the potential for and consequences of improving the energy performance in a stock of historic buildings. Key elements in the method are: categorisation of the building stock, identifying targets, assessment of measures, and life-cycle cost optimisation. In the second part of the paper, the method is applied to a typical Swedish building. The selected case study shows how the method allows for an interaction between the quantitative assessment of the technoeconomic optimisation and the qualitative assessment of vulnerability and other risks. Through a multidisciplinary dialogue and iteration it is possible to arrive at a solution that best balances energy conservation and building conservation in a given decision context.

EFFESUS Methodology for Assessing the Impacts of Energy-Related Retrofit Measures on Heritage Significance
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Improving the energy performance of historic districts and their buildings is a balancing act between retaining their heritage significance and allowing the installation of retrofit measures. This paper describes a heritage impact assessment methodology to enable such a balancing process in a well-structured and systematic way. The methodology, developed for the Energy Efficiency for EU Historic Districts' Sustainability (EFFESUS) research project, is one of six impact assessment modules for a decision-support system, a software tool under development as part of EFFESUS. In this paper, the three parts of the methodology - the heritage significance evaluation, heritage impact definitions and heritage balancing process - are discussed and their use illustrated in a case study.

Tidskriftsartikel (refereegranskat)abstract
- The paper analyses the ‘energy savings plan for existing buildings’ (EBB) introduced in Sweden after the first oil crisis of 1973, and how effects of policies on the built heritage were perceived and communicated to a wider public. A conflict between conservation aims and energy efficiency was constructed for the first time in Sweden. The programme was a huge investment made by the government to reduce the import of oil. At first, little consideration was taken to the fact that heritage values might be at risk when giving property owners financial incentives to retrofit their houses. Soon increasing knowledge about the existing building stock showed that older houses were not necessarily energy inefficient. An information campaign launched by protagonists of building conservation encouraged property owners to direct measures to the interiors of buildings, thus saving the exterior character of not just single buildings but also complete neighbourhoods. Towards the end of EBB, the field of conservation had become a more articulated voice when it came to influencing measures aiming at increased energy efficiency. Finally, the paper discusses how values constituted in the 1970s affect policy and practice today.

Tidskriftsartikel (refereegranskat)abstract
- This paper investigates the dynamic between protection of the historic environment and the application of solar energy technology on 1- or 2-family houses in Sweden. More specifically, the building code relating to the installation of photovoltaic (PV) panels on house roofs and how existing policies are implemented in Stockholm City is investigated in order to better understand the challenges in reconciling renewables and the conservation of built heritage. Especially when applied in urban areas PV panels may have a large impact on socio-cultural values, making them difficult to insta where the historic environment is to be protected from large changes. By using a mix of methods (policy analysis, case studies, and interviews) we come to the conclusion that municipalities should develop routines and guidelines that offer homeowners precise information on the potential of solar energy and requirements motivated by concern for the historic environment. Guidelines that are well-known, clear and also require homeowners to dismount exhausted panels could work both to protect built heritage and to promote more use of solar energy in some small house areas.

Tidskriftsartikel (refereegranskat)abstract
- Following a period of unprecedented building in the 1960s and 1970s, the national government of Sweden decided on a programme to promote renovations, refurbishments and extension of older buildings. The programme (abbreviated R.O.T.) was introduced in 1984 and consisted of loans and subsidies for the modernisation of houses older than 30 years, as well as information to home owners and builders on the benefits of home improvement. The target was to modernise 425,000 homes during the period 1984–1993. The programme stated that ‘the energy-saving measures must be intensified’ and ‘all out-dated and the main part of all inadequate apartments should be rebuilt to mod- ern apartments, or be demolished’. By relating the processes that formed R.O.T. to theories of decision-making, this study contributes to a better understanding of how housing policies may affect historical values in the built environment. The study reveals a conflict of interest between stakeholders. R.O.T. developed ad hoc as discourses shifted between interests. Initially, it was presented as a solution for unemployment in the building sector and a social improvement for the poor and elderly. It was not until the late 1980s that a discussion turned to the consequences for historical values.
