The debate about the financial feasibility of adaptive reuse is high among investors, planners, policy makers and heritage advocates. The old argument that it is more profitable to demolish the old brick box and replace it with a new structure have left the streets of many cities across North America and Europe with abandoned and neglected sites. Traditionally, investors and owners of such properties have shown minimal interest in investing in the rehabilitation and reuse of these buildings. Still, a growing number of successful projects featuring innovative building renovation and reuse are emerging across the province. Governments at all levels have in fact started implementing a wide range of programs and policies to stimulate private investment in old, abandoned and underutilized buildings. Such policies have led to several innovative and successful stories across the province. However, few jurisdictions have taken full advantage of the potential economic, social, and environmental opportunities that these types of investments entail. This study examines, from a private sector perspective, the economic costs and benefits of adaptive reuse in Ontario, and compares it with other types of new construction development scenarios with an aim to determine the characteristics of success. It investigates the potential effectiveness of various government policies and programs designed to stimulate investment in adaptive reuse in Ontario by conducting financial comparisons and analyses with other types of hypothetical new construction development options.

Desde as últimas décadas do século XX o tema da reabilitação de edifícios antigos para o uso habitacional passa a ser corrente em algumas cidades brasileiras. Em São Paulo, por exemplo, o tema se insere no contexto da reabilitação do centro da cidade como maneira de reintrodução do uso habitacional no local, sendo que ações públicas e privadas estão sendo desenvolvidas. Porém edifícios antigos foram construídos segundo tecnologias e regulamentos conhecidos e aplicados e os modos de vida à época de sua construção. Sempre as questões legais e normativas atuais devem ser verificadas no seu atendimento, ou as possibilidades de atualização dos sistemas e equipamentos dos edifícios a serem reabilitados. Esta Tese propõe um roteiro para análise de edifícios de apartamentos antigos, diagnosticando suas potencialidades e limitações nas adaptações às novas exigências normativas brasileiras e demandas domésticas contemporâneas. Foram selecionados itens da edificação e propostos requisitos, critérios e métodos de análise, adotando-se procedimentos para desenvolvimento, ajustes e aplicação do roteiro, como a análise física de edifícios de apartamentos antigos ainda em uso no centro de São Paulo e consulta aos seus síndicos e usuários, assim como a busca pela opinião de especialistas dos itens abordados. Igualmente o roteiro foi aplicado em edifícios de apartamentos antigos ainda em uso no centro da capital paulista e verificadas suas limitações e virtudes, a partir do diagnóstico oriundo destas aplicações. Deste modo concluiu-se que o roteiro proposto poderá se constituir em importante instrumento de apoio à fase de estudo de viabilidade dos processos de reabilitação, orientando e balizando decisões projetuais e construtivas para profissionais envolvidos nesses processos. / Since the last decades of the 20th century, the rehabilitation of old buildings for housing purposes has become a current theme in some Brazilian cities. In São Paulo, for example, the topic is part of the context of rehabilitation of the city center as a means of reintroducing housing in the area, where governmental and private actions are being developed. However, old buildings were built according to the way of life and the technologies and regulations known and applied at the time of their construction. Current legal and normative issues or the update potential of the systems and facilities of the buildings to be rehabilitated should always be verified in these conditions. This thesis proposes a script for the analysis of old apartment buildings to diagnose their potentials and limitations in the adaptation to new Brazilian normative requirements and contemporary housing demands. Construction items were selected and analysis requirements, criteria and methods were proposed. Procedures adopted for the development, adjustment and application of the script included the physical analysis of old apartment buildings still in use in the city center of São Paulo and point of view of their managers and users, as well as the consultation with experts in the topics under analysis. The script was also applied in old apartment buildings still in use in the city center of São Paulo and their limitations and virtues were verified based on the resulting diagnosis. It was concluded that the proposed script may become an important support tool in the feasibility study phase of rehabilitation processes, by guiding and mapping out design and construction decisions for professionals involved in these processes.

En ombyggnation av Sundsvalls centralstation påbörjades i augusti 2019 och ska pågå fram till augusti 2021. Ombyggnationen ska resultera i ett samlat resecentrum där en nedsänkt bussterminal ska byggas vid det befintliga stationshuset på Sundsvalls Centralstation. Projektet innefattar en stor del schaktning vid stationshusets norra långsida där den nedsänkta bussterminalen ska placeras. Schaktningen påbörjades under hösten 2019 och i mitten av december uppstod sättningsskador på stationshuset. Eftersom byggnaden är utsedd till byggnadsminne innebar sättningsskadorna ett stopp i projektet då en särskild utredning av skadorna krävdes och över projektets fortskridande. I detta examensarbete har en skadeutredning av stationsbyggnaden på Sundsvalls centralstation utförts, med målet att identifiera faktorer som vid ombyggnadsprojekt av äldre byggnader kan innebära en risk för sättningsskador samt belysa åtgärder som kan vidtas för att undvika och hantera sättningsskador. Studien består främst av en kombination av befintliga teorier och egen empiri i form av kvalitativa intervjuer. Undersökningen visar att schaktningen i kombination med rådande väder- och markförhållanden, spontmetod samt byggnadens konstruktion och grundläggning är bidragande faktorer till sättningsskadorna på stationshuset. Vid ombyggnation av äldre byggnader måste hänsyn tas till byggnadens konstruktion vilket kan vara en utmaning då kompletta ritningar ofta saknas och de ritningar som finns att tillgå överensstämmer inte alltid med verkligheten. Hänsyn måste även tas till rådande markförhållanden samt väder och klimat när arbetsmetoder för markarbeten ska väljas så att markens bärighet inte försämras. För att minimera risken för uppkomst av sättningsskador kan ett arbetsprogram tas fram där arbetsmomenten utförs i olika steg. Det finns även metoder för att förstärka grunden både i förebyggande och åtgärdande syfte.

The Long-term changes in the climate conditions have increased the need foradequate thermal comfort systems. These alternations influence extremeevents, which their intensity and frequency have increased over the past years.Moreover, this study focuses on space cooling and parameters that the systemshould have to be considered as resilient. Literature study was done to presentthe concept of resilience as well as the different methods used to provide spacecooling. In addition, the cooling systems suggested in this study, which aredistrict cooling and absorption cooling, were presented and explained.Furthermore, the study focuses on cooling demand in a group of residentialbuildings based on different thermal characteristics, which were implementedbased on building regulations from late 1960s to early 1980s. The buildingthermal properties were used as input to obtain their cooling demand by usingbuilding energy simulation tool. Based on the acquired results, an evaluationhas been made for the cooling demand of those buildings. Further analysispresented a correlation between the cooling demand and thermal properties ofthe buildings and aided in the determination of the required cooling capacity.The selection of the capacities was based on the resilience criterion as the systemhas to be able to provide adequate performance and safety for the occupantsduring extreme events. Furthermore, an assessment was done to compare thesuggested system based on their capacities and the primary energy use.
