The built environment puts the greatest pressure on the natural environment out of all human activities, so it has a fundamental obligation to be environmentally sustainable. Carbon dioxide (CO2) or carbon emissions is a significant greenhouse gas that is inevitably associated with energy use when energy is produced via the combustion of fuels. Total life cycle energy, embodied and operational energy over a building's lifetime, creates significant environmental impacts through the production of CO2. By keeping and reusing existing and historic buildings rather than discarding them and building new, the embodied energy, or the energy that is locked up, can help to mitigate future damage. These buildings already exist, which indicates that the energy consumed to build them has been applied and the carbon associated with their construction has been released. The greenest buildings are ones that are already built. They are inherently more sustainable than any new buildings even with green and zero net energy systems and can be retrofitted to become more energy efficient. To demonstrate this thesis specifically, a design project engages with an abandoned late nineteenth-century bank building in Philadelphia and transforms it into a high-performance building that is prepared for long-term use. For the immediate next use, the project creates a work environment and a new vertical expansion of residential units. The preservation field always confronts the challenge of bridging the gap between embodied energy and operational energy. In the abandoned bank, there are some aspects of this building that are near permanent and define its character, such as brick walls with masonry ornament, two bank vaults, Wissahickon Schist foundation wall, and ceiling trusses. This thesis explores new approaches to leverage the embodied energy of the permanent parts of the abandoned bank and transform it into a high-performance building. A lot of energy of the abandoned bank, the building's material, and thermal mass is still actively performing. The building's envelope, the thick masonry wall, provides a moderately good insulating effect that will temper the indoor air that also preserves its historical character both inside and outside. The embodied energy of the building's envelope is leveraged by pairing it with localized heating and cooling using a radiation and conduction system. Other approaches that increase energy performance in the existing building, include the use of phase-change material for cooling the process water, solar hot water, creating drinking water via a solar still in the skylight, and distilled water from radiant cooling surfaces. In the new construction, a thermal switch facade and double-skin facade for the residential units are proposed, along with providing flexible space with thick mobile interior wall units. / Master of Architecture / Global warming as a problem of the twenty-first-century increase concentrations of greenhouse gases in the atmosphere due to human actions like burning fossil fuels. The built environment puts the greatest pressure on the natural environment of all industrial parts, and it has a fundamental role to manage the environment sustainably. Total life cycle energy, embodied and operational energy over the lifetime of the buildings, creates significant environmental impacts through the production of CO2. Embodied energy is the whole amount of energy applied to extract the raw materials, manufacture, transport, install, and use the product across its life cycle. Assessments of the embodied energy of historic and existing buildings are helping to mitigate future damage to resources.

This thesis uses a case study of the Community Home Energy Retrofit Project (CHERP) and it analyzes the larger statewide effort in California to increase energy efficiency in existing residential buildings to reduce greenhouse gas emissions. CHERP’s primary strategy is to embed itself into a community, educate residents on the multiple benefits of energy efficiency, and inspire them to take energy-saving actions in their own homes. It then builds its own community by connecting like-minded individuals together and provides an opportunity for them to exercise their political agency. This thesis analyzes CHERP’s effort in the context of the political, social, and economic climate of California. It identifies three obstacles for widespread energy efficiency adoption: one, CHERP’s lack of funding to support permanent staff and pay for collateral materials; two, low access to energy efficiency measures for low-income households and renters; and three, a lack of high quality home performance contractors that perform energy efficiency upgrades utilizing a whole-house energy systems approach. The thesis concludes with five recommendations to overcome these issues.

Les applications des mesures dynamiques sur les bâtiments existants sont nombreuses : vérification de la vulnérabilité sismique des structures qui ont été construites avant l’apparition des règles parasismiques ; auscultation de la capacité des structures en situation post-sismique ou après des modifications au voisinage (creusement d’un tunnel à côté ou démolition des immeubles voisins par exemple). A l’heure actuelle, ce type de mesure permet le diagnostic d’une structure à l’échelle globale (toute la structure) alors que l’identification et la localisation des endommagements à l’échelle locale (chaque élément de la structure) restent encore à approfondir. Dans le cadre de cette thèse, le diagnostic à l’échelle locale des structures sera étudié. Cette thèse s’insère dans un contexte national de réévaluation des structures existantes du fait du nombre important de bâtiments à réhabiliter. Au sein du LOCIE, nous pensons que le comportement global des bâtiments est certes influencé par l’interaction sol-structure mais au moins autant par la qualité des connexions des éléments de structures entre eux. Il existe un besoin de qualification de ces connexions dont la variabilité du comportement peut provenir aussi bien de défauts de mise en œuvre (positionnement des armatures,…) que du vieillissement des structures. L’objectif principal de cette thèse est de proposer une méthode pouvant caractériser les liaisons entre les éléments de structure afin de pouvoir caler un modèle numérique. Ces caractérisations devaient être possibles à partir de mesures de sollicitations dynamiques. Une première étape de ce travail consistera à caractériser sur une partie de structure une liaison. Cela sera fait sur un portique en béton armé. Par la suite, cette méthode sera adaptée à une caractérisation au sein d’une structure de bâtiment. Pour cela nous ferons appel à la notion de sous-modèle. Un modèle numérique sera associé à cette méthode aussi bien sur la connexion simple que sur l’ensemble du bâtiment. Le travail de thèse s’appuiera sur l’utilisation et le développement de techniques concernant le traitement des données dynamiques ; la réduction de modèles ; l’expérimentation en laboratoire (échelle locale et échelle d’un élément de structure) et la modélisation numérique par éléments finis à plusieurs échelles / There are many of the examples of dynamics measurements applications in the existing building: verification of structural seismic vulnerability, which was constructed before the earthquake building code; auscultation of structural capacity in post-earthquake situation or after modification in surround environment (Excavation of tunnel or demolition the neighbour buildings for example). Currently, this measurement type enables the diagnosis a structure in global scale (a whole structure) while identification and localization of damage in local scale (each elements of the structure) remains to be explored. In this dissertation, diagnosis in locale scale will be studied. This study is significant for its contribution to the national reassessment of existing structures where there is the large number of buildings to be rehabilitated

À Paris environ 44% des bâtiments ont été construits avant 1914 avec des murs épais non isolés et des matériaux poreux, caractérisés par une forte inertie thermique et des propriétés hygroscopiques. Les propriétés hygrothermiques des matériaux utilisés dans les constructions anciennes ont des effets qui : (i) confèrent (aux bâtiments) de bonnes qualités thermiques en période estivale et (ii) contribuent à réguler la température et l’humidité relative intérieure. En France les politiques d’économie d’énergie et la régulation thermique ont abouti à la mise en place de l’isolation thermique afin de réduire les consommations d'énergie pendant l'hiver. L'installation de l'isolation thermique dans la rénovation des bâtiments existants pose cependant des difficultés. D’autre part, il est prévu que des conditions extrêmes de chaleur deviennent plus fréquentes dans des scénarios du climat futur. Ainsi, les évolutions possibles du climat futur doivent être intégrées dans l'évaluation des stratégies de rénovation dans le bâtiment ancien. Ce travail de thèse porte sur l'évaluation du comportement hygrothermique de constructions anciennes rénovées à Paris, dans des conditions météorologiques actuelles et de vague de chaleur. A l’échelle des logements un modèle a été construit sur un outil de simulation thermique dynamique, calé et validé à travers des données enregistrées dans une campagne de mesure lancée en 2014 dans les logements étudiés. À l’échelle de la paroi un modèle macroscopique en 2D est proposé afin d'étudier les transferts de chaleur et de masse dans un mur poreux constitué de plusieurs couches avec de l’isolation thermique par intérieur et par l’extérieur. / In Paris 44% of the dwellings were built before 1914 with uninsulated thick walls made of porous materials, characterized by high thermal inertia and hygroscopic properties. The hygrothermal properties of existing buildings materials have effects that: (i) give (to these buildings) good thermal qualities in summer and (ii) help to regulate indoor temperature and relative humidity. In France the energy saving policies and thermal regulation have resulted in the implementation of thermal regulation to reduce energy consumption during winter. Though the installation of thermal insulation in existing buildings poses a number of difficulties. Moreover, it is expected that extreme heat conditions become more frequent in future climate scenarios. Thus, the possible evolutions of future climate must be integrated into the evaluation of renovation strategies in old buildings. This thesis focuses on the assessment of the hygrothermal behavior of old renovated Parisian buildings, in current and heat wave weather. At the building scale (housing), a model was built in dynamic thermal simulation tool. The model was calibrated and validated through recorded data from a measurement campaign launched in 2014 on the studied housings. At the wall scale, a macroscopic model in 2D is proposed to study the heat and mass transfer through a multilayered porous wall, renovated with internal thermal insulation and external thermal insulation.

Sous nos latitudes, l’usage des bâtiments existants et les consommations énergétiques associées (chauffage, climatisation, ventilation, eau chaude sanitaire, éclairage et autres usages) sont responsables d’impacts considérables sur l’Environnement. De plus, le renouvellement du parc existant étant inférieur à 1% par an, dans la plupart des pays développés, la réhabilitation des bâtiments constitue un levier majeur de réduction des consommations d’énergie et des émissions de gaz à effet de serre. Cependant, l’identification de stratégies optimales de réhabilitation énergétique, incluant la planification des actions dans le temps, demeure une problématique complexe pour les acteurs de la Construction. Ces travaux de thèse visent à produire des connaissances afin de contribuer à l’aide à la décision pour l’identification de programmes efficaces de réhabilitation énergétique, à partir de méthodes d’optimisation multicritères. Les solutions (programmes séquentiels de réhabilitation énergétique) sont optimisées en termes de composition et de phasage. La composition est définie par la combinaison de mesures de réhabilitation mise en oeuvre. Celles-ci concernent l’enveloppe des bâtiments (isolation thermique, remplacement des fenêtres, surfaces de fenêtres) et le remplacement des équipements de chauffage, ventilation et production d’ECS. Pour chacune des mesures, plusieurs alternatives sont envisagées. Le phasage correspond à la permutation de ces mesures, définissant la séquence de mise en oeuvre. Les solutions sont évaluées sur une base multicritère et sur le cycle de vie. Les fonctions objectifs ciblent les impacts environnementaux de l’ACV (Analyse de Cycle de Vie), des indicateurs économiques, le bien-être des occupants par le confort thermique adaptatif en été. Des modèles d’ACV et d’analyse du coût du cycle de vie, utilisant la simulation thermique dynamique pour le calcul des besoins de chauffage et des températures intérieures, ont été développés pour l’évaluation des performances des solutions. Etant donnée la nature mathématique du problème (multicritère, combinatoire, à variables discrètes et à fonctions objectifs implicites non-linéaires), deux méthodes d’optimisation multicritères sont étudiées : les algorithmes génétiques (NSGA II) et la programmation dynamique. Dans l’approche génétique, la modélisation des solutions, sous la forme d’un couple de chromosomes, permet d’identifier des programmes séquentiels efficaces de réhabilitation énergétique et d’analyser les surfaces de compromis, en termes de définition et performances des solutions, de compromis entre les critères de décision. A partir de la représentation du problème par un graphe séquentiel, la programmation dynamique permet alors de comparer les solutions approchées issues de l’algorithme génétique, ou d’approches court-termistes, au front de Pareto exact. L’optimisation exacte a également été exploitée pour analyser la sensibilité des solutions à différents paramètres de modélisation dont le comportement des occupants, l’évolution des prix de l’énergie, la durée de vie des composants de réhabilitation. Les contraintes budgétaires s’appliquant au projet de réhabilitation ont été ensuite intégrées dans un algorithme génétique multicritère sous contraintes, adapté à l’étude des stratégies de réhabilitation sous la contrainte d’un plan de financement. Enfin, l’approche génétique a été étendue depuis l’échelle du bâtiment à celle du par cet l’optimisation exacte a été utilisée pour caractériser les typologies de bâtiment en réhabilitation. L’intérêt des différentes méthodes est illustré sur une étude de cas (…) / Under our latitudes, existing buildings energy consumptions, related to heating, cooling, ventilation, domestic hot water (DHW), lighting and other uses, are responsible for significant environmental burdens. Moreover, existing buildings annual replacement rate being lower than 1%, in most developed countries, existing stock retrofit represents a major lever to reach commitments on climate change and non-renewable energy consumption mitigation. However, the identification of optimal sustainable retrofit programs, including actions planning over a time period, is still a difficult task for professionals.This thesis aims at producing knowledge in order to contribute to decision support for efficient energy retrofit programs identification, through the application of different multi-criteria optimization techniques. The solutions (sequential building energy retrofit programs) are optimized both on their content and planning. The content refers to the combination of retrofit measures considered. These address holistically building envelopes (thermal insulation, windows replacement, window to wall ratios), and the replacement of equipment for ventilation, heating and DHW production. For each of these measures, various options are considered. The planning corresponds to the permutation of these measures, defining a time sequence for implementation. The solutions are evaluated on a multi-criteria and life cycle basis. The objective functions considered target environmental impacts evaluated using LCA (Life Cycle Assessment), some financial indicators and occupants' well-being through thermal comfort in summer. Life cycle assessment and life cycle cost models, using building dynamic thermal simulation for heating load and thermal comfort evaluation, are implemented to assess solutions performances.Considering the problem mathematical nature (multi-criteria, combinatorial, discrete variables, implicit non-linear objective functions), two suitable multi-criteria optimization techniques have been studied: multi-criteria genetic algorithm (NSGA-II) and dynamic programming. In the genetic approach, the modelling of each solution by a pair of chromosomes allowed to identify efficient sequential energy retrofit programs and analyse Pareto compromise surfaces, in terms of solutions features, performances and relationships in between criteria. Then, the representation of the problem on a sequential graph enabled us to apply dynamic programming, to compare both the genetic approximate solutions, and the results of some short- term approaches to the exact Pareto frontier. The search for exact solutions also been exploited to perform sensitivity analysis on different modelling parameters such as heating temperature setting, energy prices evolution or materials lifespan. Real life budget constraints have been incorporated to build a constrained multi-criteria genetic optimisation method, suitable to study retrofit strategies under financing plans. At the end, the genetic approach has been extended from building scale to stock scale and exact optimization has been used to characterize building types in terms of energy retrofit.The benefits of these methods have been illustrated on case studies. Knowledge has been produced in terms of multi criteria optimization methodology, applied to sequential energy retrofit, and understanding of building stocks evolution. These developments contribute to decision aiding; providing decision makers with efficient energy retrofit strategies and a description of the comprise surface, at the building or building stock scale, on a multi- criteria basis, over life cycle

Numerous reinforced concrete buildings vulnerable to earthquake induced collapse have been constructed in seismic zones prior to the 1970s. A major contributor to building collapse is the loss of axial load carrying capacity in non-seismically detailed columns. Experimental investigations have shown that non-seismically detailed columns will only experience axial failure after shear failure and subsequent lateral shear strength degradation have occurred. Therefore, column shear failure and degrading behavior must be modeled accurately before axial collapse algorithms can be properly implemented. Furthermore, accurate modeling of the degrading lateral-load behavior of columns is needed if lateral load sharing between structural elements is to be assessed with reasonable accuracy during seismic analyses. A calibrated analytical model was developed that is capable of estimating the lateral strength degrading behavior of RC columns prone to shear failure. Existing analytical models poorly approximate nonlinear column behavior and require several nonphysical damage parameters to be defined. In contrast, the proposed calibrated model provides the engineering community with a valuable tool that only requires the input of column material and geometric properties to simulate column behavior up to loss of lateral strength. In developing the model, a database of RC columns was compiled. Parameters extracted from database column-tests were scrutinized for trends and regression models relating damage parameters to column physical properties and boundary conditions were produced. The regression models were implemented in the degrading analytical framework that was developed in this project. Two reinforced concrete columns exhibiting significant inelastic deformations prior to failing in shear were tested in support of the analytical work. A newly developed Vision System was used to track a grid of targets on the column face with a resolution of three-thousands of an inch. Surface column deformations were measured to further the understanding of the fundamental changes in column behavior that accompany shear and axial failure and validate the proposed analytical model. This research provides the engineering community with an analytical tool that can be used to perform nonlinear dynamic analysis of buildings that are at risk of collapse and help engineers improve retrofit techniques. Further insight into shear behavior attained through this project is an important step toward the development of better shear and axial degradation models for reinforced concrete columns. / text

I Sverige har det funnits en utbredd bostadsbrist under de senaste decennierna och utvecklingen har skett mot större förtätning, målsättningen är att skapa städer med ekonomisk- och socialhållbarhet. Det bortses dock från att tätt planerade städer riskerar att inskränka på dagsljustillgången för de boende. Nordiska klimat med mörka vintermånader och solen som står lågt på himlen skapar en stor utmaning. Forskning visar att god tillgång till dagsljus är viktig för människors hälsa och välbefinnande och det är därför viktigt att skydda dagsljustillgången för boende i svenska städer. Trots detta så är den svenska lagstiftningen för skydd av dagsljus för befintliga bostäder svårtolkad med vaga riktlinjer på vad som kan anses som en rimlig minskning av dagsljustillgång.Denna studie undersöker den aktuella lagstiftningen i Sverige för skydd av dagsljusåtkomst i befintliga byggnader. Med fokus på befintliga bostadshus används resultatet från fördjupade fallstudier över två områden för att undersöka möjligheter för hur en framtida kravställning kan se ut. Förslaget på kravställningen diskuteras med hänsyn till nuvarande praxis.Studiens resultat påvisar att en förtätning av staden i många fall leder till otillräcklig dagsljustillgång i befintliga bostäder och att dagens kravställning för dagsljushantering är bristfällig. Att säkerställa tillräcklig dagsljustillgång i bostäder är nödvändigt redan vid planläggning. Studien visar på ett varierande resultat vid användning av nuvarande föreskrifter och allmänna råd givna av Boverket och den europeiska standarden SS-EN 17037:2018. SS-EN 17037:2018 påvisar ett resultat som är känsligare för förändringar i omgivningen. I kombination med att standarden beskriver den faktiska upplevelsen av ljuset i rummet gör det den till ett lämpligare mätetal för dagsljushantering. Om visionen för framtidens städer ska vara samma som idag bör kravställningen på dagsljus utvecklas. / Over the past couple of decades Sweden has suffered from a housing shortage and the trend towards densification due to ambition of creating cities with economic and social sustainability. It is often missed however that tightly planned cities run the risk of restricting daylight access for occupants. Nordic climates, with their relatively low solar angles and dark winter months pose a particular challenge. An increasing body of research however shows that good access to daylight is crucial to human health and well-being. As such, it stands to follow that protecting daylight access for those living in the city is of great societal benefit. Yet the current Swedish national regulatory structure for protection of daylight access in existing properties gives only vague guidance as to what constitutes an unreasonable reduction of daylight access and/or remedy when an unreasonable reduction in daylight access exists. The resulting uncertainty presents a degree of unwelcome risk to building projects.This study reviews the current state of Swedish legislation for protection of daylight access in existing buildings. With focus on residential buildings it uses results from in-depth case studies to examine possible structures for what a future regulatory framework might look like and discusses the proposal in the context of current Swedish praxis.The study found that in many cases, densification of the city leads to insufficient daylight in existing housing and that today's requirements for natural daylight are inadequate. Ensuring adequate daylight is possible already when planning and should be considered to create a society where human health is secured. The study shows varying results when using current Swedish regulations and the European standard SS-EN 17037:2018. SS-EN 17037:2018 demonstrates a result that is more sensitive to changes in the environment, combined with the standard describing the actual experience of the light in the room making it a more suitable measurement for assessing changes in daylight access for existing properties.

I dagsläget består Stockholm city mestadels av kontor och handel vilket innebär att det blir folktomt kvällstid. För att göra innerstaden mer levande behövs en stadsdel med blandade funktioner där människor rör sig samt både bor och arbetar. Den grundfunktion som i dagsläget saknas i denna del av Stockholm är bostäder. Ett problem med att förse City med fler bostäder är dock tillgång till markyta då området redan är så pass exploaterat. I arbetet undersöks det om City kan göras till en funktionsblandad och mer levande stadsdel genom att förse området med fler bostäder. Med anledning av den begränsade tillgången till markyta i stadsdelen undersöks alternativet att bygga bostäder på befintliga byggnader. Arbetet visar ett förslag för påbyggnad av bostäder på tak i City samt undersöker förutsättningarna för detta. Påbyggnaden görs på en befintlig byggnad och ska genom sin utformning spegla en god boendemiljö samt samspela med den omgivande bebyggelsen. Förslaget omfattar ett taklandskap med bostäder i form av parhus och utevistelseytor. Att föra in fler bostäder genom påbyggnation av befintlig bebyggelse i City är en lämplig och generellt tillämpbar lösning med anledning av stadsdelens och bebyggelsens förutsättningar. / Stockholm City is currently well composed in the aspect of commercial and public service. A consequence to this is a desolated City during the late night. A requirement to accomplish a more living inner city is a satisfying combination of functions whereas people are in motion between the home, work and other social activities. The main function missing today in City is habitats. A problem with supplying more accommodations in City is however the limited asset of ground area due to exploitation. In this thesis research is made whether it is possible to transform City into a mixed-function and thereby urban living area. With reference to the limited asset of ground area aswell as the opportunity to preserve the existing qualities that occupy these areas, a research is conducted for the purpose of more residential buildings with the method of expansion of existing buildings. The result of this thesis is a proposition for residential buildings on roof tops in City and the requirements for such project are being analyzed. The additional building is added to a specific building and by its shaping reflects a good residential environment and a design appropriate to the surrounding built-up area. The proposal consists of a rooftop landscape with eight pairs of houses. To insert accommodations throughout expansion of existing buildings generally is applicable in City and therefore an adequate solution to the problem considering the problems in the area.

Para la adaptación de los edificios a este cambio de paradigma es necesario reducir el impacto energético de su utilización de una forma controlada. El alcance de este objetivo precisa de bases metodológicas contrastadas y herramientas útiles y eficaces. La tesis de investigación desarrolla y analiza tres metodologías de caracterización del comportamiento térmico de los edificios existentes. Estas metodologías consideran el empleo de técnicas de monitorización térmica y simulación energética, diferentes escenarios futuros de cambio climático y el empleo de tecnologías de escaneado térmico tridimensional, para la creación y el ensayo predictivo de modelos térmicos de edificios. Cada una de estas metodologías ha sido aplicada a un caso de estudio diferente. Los ensayos de simulación que se han realizado, junto a los análisis y las discusiones de los resultados que se han obtenido, han permitido conocer los resultados de cada una de estas metodologías. Los dos primeros casos del estudio caracterizan el comportamiento térmico de edificios tradicionales en un clima mediterráneo, así como comportamientos futuros bajo diferentes escenarios de cambio climático. El tercer caso ensaya una metodología de monitorización que incluye la utilización de modelos termográficos tridimensionales que proporciona un mayor rendimiento operacional en los procesos de modelado energético y nuevas opciones de calibración de los modelos térmicos de edificios. / [CA] El canvi climàtic i d'escassetat de recursos energètics fòssils exigeixen un canvi urgent dels models d'habitar.

To adapt buildings to this paradigm shift, it is necessary to reduce the energy impact of their use in a controlled manner. The achievement of this objective requires tested methodological bases and useful and effective tools. The research thesis develops and analyzes three methodologies for characterizing the thermal behavior of existing buildings. These methodologies consider the use of thermal monitoring and energy simulation techniques, different future climate change scenarios and the use of three-dimensional thermal scanning technologies, for the creation and predictive testing of thermal models of buildings. Each of these methodologies has been applied to a different case study. The simulation tests that have been carried out, together with the analyzes and discussions of the results obtained, have allowed us to know the scope of each of these methodologies. The first two cases of the study characterize the thermal behavior of traditional buildings in a Mediterranean climate, as well as future behavior under different climate change scenarios. The third case tests a monitoring methodology that includes the use of three-dimensional thermographic models that provide greater operational performance in energy modelling processes and greater possibilities for calibrating the thermal models of buildings. / Pérez Andreu, V.
