    Building Maintenance Strategies: Planning under Uncertainty
    (Property Management., 2012) Lind, Hans; Muyingo, Henry
    The purpose of this article is to critically evaluate maintenance strategies and determine to what extent models from other sectors can be applied to building maintenance. The paper is a theoretical paper based on a number of Swedish studies, both case studies and questionnaires. From these a number of stylized facts have been identified and the purpose is to explain and draw conclusions from these. The main finding is that there are a number of specific uncertainties that affect building maintenance planning making more detailed long‐term plans less meaningful. A new structure for maintenance is proposed focusing on long‐term strategies goals for various buildings/components and then short run adjustments when new information comes up. The case for the new model needs to be strengthened by further studies, including studies from other countries. Maintenance activities will be more important as the large building stock from the 1950s and 1960s needs to be renovated or demolished. A rational structure and realistic expectations concerning maintenance planning is then important. The most important contribution of the article is to underline the importance of different types of uncertainty for the structure of maintenance planning for building.

    Challenges in Property Management within the Swedish Cooperative Housing Sector
    (Royal Institute of Technology, 2016) Muyingo, Henry
    The paper investigates the challenges to property management in the tenant-owner cooperative (TOC) housing sector in Sweden which accounts for 22% of the housing stock in the country as compared to an average of 10% in the rest of Europe. A qualitative descriptive approach is used in the paper in which semi-structured interviews of governing committee members in 12 TOCs; a questionnaire on operation and management strategies sent to chairpersons in 725 TOCs as well as a questionnaire on issues related to energy efficiency sent to chairpersons in 91 TOCs provide the empirical data. This is complemented by an analysis of financial reports.

    Critical Reflections on the Concept of Maintenance
    (International Journal of Strategic Property Management, 2012) Lind, Hans; Muyingo, Henry
    The purpose of the paper is to critically evaluate the conceptual distinction between investment and maintenance. The study starts from a number of definitions in the literature and discusses these from the perspective of standard investment theory. The article argues that the standard concept of investment covers all relevant decisions and also puts the focus on the future consequences of decision and not whether it restores an earlier standard or not. The research implications are that investment and maintenance planning need to be analysed together and that the distinction between investment and maintenance is uninteresting from a decision theoretic and resource allocation perspective. The practical implications of the article are that what usually is called investment planning and maintenance planning need to be integrated. The originality in the paper lies primarily in the questioning of the usefulness of the concept of maintenance in a dynamic age where the relation to earlier characteristics and functions becomes less and less interesting. The role of the maintenance concept is now primarily related to various administrative systems (accounting, taxation) but is not so relevant from a forward looking resource allocation perspective.

    Lessons in Community Owned PV from Swedish Multi-Family Housing Cooperatives
    (Hamburg, 2015) Sommerfeldt, Nelson; Muyingo, Henry
    With increasing population shifts to urban areas and demands for post-war energy efficient renovationsacross Europe, solar photovoltaic (PV) deployment in multi-family housing will play an increasingly important roletowards meeting renewable energy, climate, and sustainability goals. This paper describes the stories of threeSwedish residential cooperatives who have installed large-scale PV systems across multiple buildings on their estates.In all cases, reduced operating costs were the original primary motivator; however unforeseen cost increases, changesin policy, and excess supply in the electricity market have made economic success less likely than originallyexpected. Regardless, the owners consider their projects a success due in part to short term social and long-termenvironmental benefits, which were originally less important and difficult to quantify. We can conclude thatcommunity owned PV offers more than just economic benefits, and Sweden’s unique ownership and managementstructure of residential cooperatives can offer insights towards increased deployment in other nations in Europe.

    Organizational Challenges in the Adoption of Building Applied Photovoltaics in the Swedish Tenant-Owner Housing Sector
    (Sustainability, 2015) Muyingo, Henry
    Sweden has committed itself to comply with EU-directive 2009/28/EC on energy from renewable sources and 2012/27/EU on improvement in the efficiency of energy. Measures in the existing housing stock, such as installing photovoltaics (PV), provide a means of contributing to the goals above. The purpose of this paper is to study how the organization of property management and the decision-making structure in tenant-owner cooperatives (TOCs) in Sweden facilitates or hampers the adoption of large-scale residential building applied photovoltaics (BAPV) in this housing sector. Data collected through seven semi-structured interviews of executive board members in seven housing cooperatives were descriptively analyzed and the results indicate that the decision to adopt BAPV in TOCs does not follow the common frameworks of adoption of innovations. The choice by TOCs to adopt BAPV depends more on the wish to lower operating costs than on efforts to promote a sustainable environment and various principal-agency problems during the decision-making process, as well as during the implementation phase create challenges to the adoption of BAPV. There is a need to strengthen the quality and management of knowledge, as well as procurement proficiency in the TOCs in order to harness the potential for BAPV in the sector.

    Photovoltaic Systems for Swedish Prosumers A technical and economic analysis focused on cooperative multi-family housing
    (KTH Royal Institute of Technology, 2016) Sommerfeldt, Nelson; Muyingo, Henry; Klintberg, Tord af
    This report is designed to be a comprehensive information resource for Swedish prosumers considering an investment in solar PV systems. The target audience are multi-family cooperative houses, however much of the information is applicable to other building owners and solar energy more broadly. The primary question to be answered; is a rooftop PV investment profitable in Sweden? Naturally there are many variables that can affect the answer; therefore a Monte Carlo methodology is used to convert the uncertainties into risks, where the results can be presented as probabilities rather than a vast collection of sensitivity analyses. Several policy scenarios are tested, where the relative impact of each current program on profitability can be seen.
