Introduktion (och mål) - I dagens samhälle är klimatet en viktig fråga och bygg- och anläggningssektorn står för stora mängder koldioxidutsläpp. Denna forskning syftar till att studera hur klimatavtrycket från VA-entreprenader kan minskas. Metod – För att genomföra studien har en VA-entreprenad, utförd av Skanska, studerats genom en fallstudie. I studien har data samlats in genom interna dokument och intervjuer. Resultat – Dokumenten visar att lokal masshantering och användning av HVO som bränsle i stället för diesel ger minskade koldioxidutsläpp i projektet och intervjuerna bekräftar detta. I intervjuerna nämns också att grön asfalt används för att minska koldioxidutsläppen. Möjligheterna för att minska klimatavtrycket i framtiden som tas upp är bland annat eldrivna grävmaskiner och transporter samt biobindemedel i asfalten. De hinder som intervjupersonerna nämner för att minska klimatavtrycket är bland annat brist på miljövänligt VA-material i plast, laddning av eldrivna maskiner och den extra kostnaden det blir för att arbeta miljövänligt. Analys – De klimatanpassningar som redan görs ses som relativt enkla tekniker medan möjligheterna för att i framtiden minska utsläppen just nu hindras av kostanden och att vissa tekniker inte är tillräckligt utvecklade. Diskussion – I studien framgår att användning av HVO och grön asfalt är åtgärder för att minska koldioxidutsläppen och att dessa stärks av tidigare forskning. Lokalmasshantering är också en åtgärd för att minska koldioxidutsläppen men konstateras vara svår att koppla till tidigare studier. Möjligheterna med att minska utsläppen genom eldrivna grävmaskiner och transporter bekräftas genom tidigare forskning vilket också användningen av biobindemedel i stället för bitumen i asfalten gör. Bristen på miljövänliga VA-material i plast bekräftas i tidigare studier vilket också merkostnaden för HVO i jämförelse med diesel gör. / Introduction (and aim) – In today's society, the climate is an important issue and the building and construction sector accounts for large amounts of carbon dioxide emissions. This research aims to study how the climate footprint from water and sewer contracts can be reduced. Method – To accomplish the study, a water and sewer contract carried out by Skanska has been studied through a case study. In the study data has been collected through internal documents and interviews. Results – The documents show that “local mass handling” and the use of HVO as fuel instead of diesel, generates reduced carbon dioxide emissions in the project and the interviews confirm the information. Also mentioned in the interviews is that green asphalt is used to reduce carbon dioxide emissions. Possibilities for reducing the climate footprint in the future that are brought up include electric-powered excavators and transport as well as bio-binders in the asphalt. The obstacles that are mentioned in the interviews to reduce the climate footprint are, among other things, lack of environmentally friendly plastic materials for water and sewer enterprisers, charging of electric machines and the extra cost of working in an environmentally friendly way. Analysis – The climate adaptations that are used today is seen as relatively simple technologies, while the possibilities for reducing emissions in the future are currently stopped by the increased cost and that certain technologies are not developed sufficiently. Discussion – The study shows that the use of HVO and green asphalt are ways to reduce carbon dioxide emissions and that these are supported by previous research. Local mass handling is also a way to reduce carbon dioxide emissions but has been difficult to confirm by previous studies. The possibilities of reducing emissions through electric excavators and transports are confirmed by previous research, and the use of bio-binders instead of bitumen in the asphalt is also confirmed. The lack of environmentally friendly plastic material for water and sewer enterprisers is confirmed in previous studies, also the additional cost of HVO compared to diesel is confirmed.

<p>  </p> <p>Traditional manual code compliance checking process is a time-consuming, costly, and error-prone process that has many shortcomings (Zhang & El-Gohary, 2015). Therefore, automated code compliance checking systems have emerged as an alternative to traditional code compliance checking. However, computer software cannot directly process regulatory information in unstructured building code texts. To support automated code compliance checking, building codes need to be transformed to a computer-processable, structured format. In particular, the problem that most automated code compliance checking systems can only check a limited number of building code requirements stands out.</p> <p>The transformation of building code requirements into a computer-processable, structured format is a natural language processing (NLP) task that requires highly accurate part-of-speech (POS) tagging results on building codes beyond the state of the art. To address this need, this dissertation research was conducted to provide a method to improve the performance of POS taggers by error-driven transformational rules that revise machine-tagged POS results. The proposed error-driven transformational rules fix errors in POS tagging results in two steps. First, error-driven transformational rules locate errors in POS tagging by their context. Second, error-driven transformational rules replace the erroneous POS tag with the correct POS tag that is stored in the rule. A dataset of POS tagged building codes, namely the Part-of-Speech Tagged Building Codes (PTBC) dataset (Xue & Zhang, 2019), was published in the Purdue University Research Repository (PURR). Testing on the dataset illustrated that the method corrected 71.00% of errors in POS tagging results for building codes. As a result, the POS tagging accuracy on building codes was increased from 89.13% to 96.85%.</p> <p>This dissertation research was conducted to provide a new POS tagger that is tailored to building codes. The proposed POS tagger utilized neural network models and error-driven transformational rules. The neural network model contained a pre-trained model and one or more trainable neural layers. The neural network model was trained and fine-tuned on the PTBC (Xue & Zhang, 2019) dataset, which was published in the Purdue University Research Repository (PURR). In this dissertation research, a high-performance POS tagger for building codes using one bidirectional Long-short Term Memory (LSTM) Recurrent Neural Network (RNN) trainable layer, a BERT-Cased-Base pre-trained model, and 50 epochs of training was discovered. This model achieved 91.89% precision without error-driven transformational rules and 95.11% precision with error-driven transformational rules, outperforming the otherwise most advanced POS tagger’s 89.82% precision on building codes in the state of the art.</p> <p>Other automated information extraction methods were also developed in this dissertation. Some automated code compliance checking systems represented building codes in logic clauses and used pattern matching-based rules to convert building codes from natural language text to logic clauses (Zhang & El-Gohary 2017). A ruleset expansion method that can expand the range of checkable building codes of such automated code compliance checking systems by expanding their pattern matching-based ruleset was developed in this dissertation research. The ruleset expansion method can guarantee: (1) the ruleset’s backward compatibility with the building codes that the ruleset was already able to process, and (2) forward compatibility with building codes that the ruleset may need to process in the future. The ruleset expansion method was validated on Chapters 5 and 10 of the International Building Code 2015 (IBC 2015). The Chapter 10 of IBC 2015 was used as the training dataset and the Chapter 5 of the IBC 2015 was used as the testing dataset. A gold standard of logic clauses was published in the Logic Clause Representation of Building Codes (LCRBC) dataset (Xue & Zhang, 2021). Expanded pattern matching-based rules were published in the dissertation (Appendix A). The expanded ruleset increased the precision, recall, and f1-score of the logic clause generation at the predicate-level by 10.44%, 25.72%, and 18.02%, to 95.17%, 96.60%, and 95.88%, comparing to the baseline ruleset, respectively. </p> <p>Most of the existing automated code compliance checking research focused on checking regulatory information that was stored in textual format in building code in text. However, a comprehensive automated code compliance checking process should be able to check regulatory information stored in other parts, such as, tables. Therefore, this dissertation research was conducted to provide a semi-automated information extraction and transformation method for tabular information processing in building codes. The proposed method can semi-automatically detect the layouts of tables and store the extracted information of a table in a database. Automated code compliance checking systems can then query the database for regulatory information in the corresponding table. The algorithm’s initial implementation accurately processed 91.67 % of the tables in the testing dataset composed of tables in Chapter 10 of IBC  2015. After iterative upgrades, the updated method correctly processed all tables in the testing dataset. </p>

<p dir="ltr">Building Information Modeling (BIM) supports engineering and performance analysis for buildings and civil infrastructure from the initial design stage. BIM offers engineers access to building and infrastructure objects, along with their associated data, which can be utilized across various platforms to develop analytical models. However, the interoperability between BIM and analytical models is still limited and challenging. One such limitation and challenge is in the interoperability between BIM and Building Energy Modeling (BEM). Despite the fact that interoperability of geometry and material information between BIM and BEM has been extensively investigated, the interoperability of heating, ventilation, and air conditioning (HVAC) information, which is a crucial part in BEM, was underinvestigated. Another limitation is that the shared objects frequently lose their identification across different models during the processes of their creation, design iterations, and model transformation. In addition, current building and civil infrastructure projects mainly rely on Portable Document Format (PDF) plans as the official deliverables and documents to be stored, communicated, and transferred among different stakeholders. The transition from 2D PDF plans to 3D BIM remains challenging because manually creating a BIM instance model from 2D drawings can be laborious, time-intensive, and susceptible to errors.</p><p dir="ltr">To address these gaps, this dissertational research introduces new Industry Foundation Classes (IFC)-based algorithmic methods that utilize the state-of-the-art Data-driven Reverse Engineering Algorithm Development (D-READ) method and the invariant signatures of architecture, engineering, and construction (AEC) objects to (1) develop algorithms that can extract the information from 2D PDF drawings and reconstruct the 3D semantically segmented and enriched BIM instance models, (2) develop object mapping algorithms for interfacing BIM and analytical models (e.g., BEM, structural analysis models, etc.) by automatically mapping building objects, and (3) iteratively develop the HVAC information transformation algorithm between BIM and BEM. Following the proposed methods, algorithms were developed to (1) semi-automate the creation of semantically segmented and enriched 3D IFC-based bridge BIM instance models using 2D PDF bridge plans, (2) map space objects between BIM instance models and BEM (OpenStudio model) based on their invariant signatures, and (3) transform HVAC objects from IFC-based BIM instance models to BEM with all the necessary information for energy simulation, using (1) PDF drawings for 12 bridges located in various parts of Indiana, (2) a 2-story duplex apartment building, and (3) a 2-story office building model and a 2-story residential building model, respectively.</p><p dir="ltr">The developed algorithms were tested on three cases: (1) the PDF information extraction algorithm was tested on six bridges, which achieved 97.7% precision and 94.4% recall. In addition, it decreased the time required to create bridge BIM instance models by 94.9% compared to the manual approach; (2) the object mapping algorithm was evaluated using a 4-story office building model containing 82 spaces. The results demonstrated that the algorithm attained 90% precision and 90% recall in mapping space objects. Additionally, a 4.88% improvement in the accuracy of energy simulation results was observed when compared to simulations without space mapping; (3) the HVAC transformation algorithm was tested on two models with distinct HVAC systems: a 4-story office building model featuring a boiler radiator system and a 2-story clinic building featuring a VAV system. The algorithm achieved transformation accuracies of 97.5% and 98.7%, respectively, compared to manually created evaluation models in OpenStudio. Additionally, the algorithm-generated models demonstrated satisfactory performance with regard to precision, with less than 9.6% error in total annual energy consumption compared to the evaluation models.</p><p dir="ltr">This dissertational research introduces a new IFC-based approach to fill the forementioned research gaps in BIM interoperability for buildings and civil infrastructures. It facilitates improved accessibility compared to a proprietary workflow and will contribute to filling informational gaps (1) between 3D BIM and 2D PDF drawings, and (2) between BIM and analytical models. It builds a solid foundation for achieving (1) automated BIM reconstruction using 2D plans, and (2) smooth, accurate, and fully-automated HVAC objects transformation between BIM and BEM, for complete BIM-BEM interoperability. The proposed approach can also be leveraged to further expand BIM interoperability support by providing a novel data-driven approach for building and civil infrastructure projects.</p>

To reach the net-zero carbon goal by 2045, the Swedish government want to push the building and construction sector to lower their greenhouse gas emissions. This push is performed by implementing a law requiring building developers to perform a climate declaration over greenhouse gas emissions, to receive a building’s final clearance. The climate declaration is limited to only include emissions from material extraction until completed building. However, there is a varying knowledge level in the industry regarding how to perform a climate declaration as well as how different materials impact the result. Therefore, this study aims to bring clarity concerning the topic, by investigating where the major and minor climate impacts occur in a building process. Additionally, the impact of different insulations materials and how they influence the result of a climate declaration is studied. To answer the research questions, a climate declaration is performed on a Swedish preschool. The insulation material in the building is altered between glass wool, stone wool, cellulose fibre, foam glass, and polystyrene insulation in different scenarios to see how it impacts the result. The stone wool scenarios use both carbon neutral and non-carbon neutral insulation. Cellulose fibre uses both loose wool with data from an EPD and board insulation with data from Boverket’s climate database in the scenarios. The major climate impact derives from the product stage (A1–A3), meaning material selection have a significant impact on the climate declaration result. The building element with the highest climate impact is the inner walls followed by the foundation, while the floor construction, roof and outer walls have the lowest climate impact. On a material level, plaster board, building plywood and concrete have the highest climate impact in the reference building. The cedar panel have the lowest climate impact and is the only carbon negative material in the reference building. However, this is due to different assumptions made in the climate impact data concerning the binding of carbon in organic materials. The results showed that the insulation material with the highest climate impact is non-carbon neutral stone wool that is 16 % higher than the original construction with glass wool, while loose cellulose wool has the lowest climate impact. The climate impact from the scenario with non-carbon neutral stone wool in the wall and roof construction is 33 % higher compared to the corresponding loose cellulose wool scenario. The scenario with the lowest climate impact, with loose cellulose wool, is approximately 13 % lower than the corresponding glass wool scenario. The carbon neutral stone wool scenario has a similar result to glass wool. Foam glass has a 9.5 % higher climate impact compared to polystyrene insulation in the foundation. Regarding the selection of insulation material, it influences the climate declaration by changing the climate impact. The influence derives from a combination of climate impact per unit and material quantity used in the building. The material quantity is partly dependant on the thermal conductivity (λ-value) of the insulation material. The climate declaration shows a limited view of a building’s environmental impact for a limited part of its lifecycle. Therefore, we would recommend additional lifecycle stages and environmental impacts to be part of the climate declaration in the future, as a means to avoid suboptimization and unintentional problem shifting. / För att nå klimatneutralitetsmålet 2045 vill den svenska regeringen driva bygg- och fastighetssektorn till att sänka sina växthusgasutsläpp. Denna insats utförs genom att införa en lag som kräver att byggherrar utför en klimatdeklaration över växthusgasutsläpp för att få ett slutbesked för byggnaden. Klimatdeklarationen är begränsad till att endast omfatta utsläpp från materialutvinning fram till färdig byggnad. Det finns dock en varierande kunskapsnivå i branschen om hur en klimatdeklaration utförs samt hur olika material påverkar resultatet. Därför syftar denna studie till att ge klarhet angående ämnet genom att undersöka var de större och mindre inflytandena på klimatpåverkan förekommer i en byggprocess. Dessutom studeras effekterna av olika isoleringsmaterial och hur de påverkar resultatet av en klimatdeklaration. För att besvara frågeställningarna utförs en klimatdeklaration på en svensk förskola. Isoleringsmaterialet i byggnaden ändras mellan glasull, stenull, cellulosafiber, skumglas och cellplast i olika scenarier för att se hur det påverkar resultatet. I stenullscenarierna används både koldioxidneutral och icke-koldioxidneutral isolering. Cellulosafibrer använder både lösull med data från en EPD och skivisolering med data från Boverkets klimatdatabas i scenarierna. Den största klimatpåverkan kommer från produktstadiet (A1–A3), vilket innebär att materialvalet har en betydande inverkan på klimatdeklarationsresultatet. Byggnadselementet med störst klimatpåverkan är innerväggarna följt av grunden, medan bjälklaget, taket och ytterväggarna har lägst klimatpåverkan. På materialnivå har gipsskivor, plywood och betong den högsta klimatpåverkan i referensbyggnaden. Cederpanelen har lägst klimatpåverkan och är det enda koldioxidnegativa materialet i referensbyggnaden. Detta beror dock på olika antaganden i klimatpåverkan angående bindningen av kol i organiska material. Resultaten visade att isoleringsmaterialet med den högsta klimatpåverkan är icke-koldioxidneutral stenull, som är 16 % högre än originalkonstruktionen med glasull, medan lös cellulosaull har lägst klimatpåverkan. Klimatpåverkan från scenariot med icke koldioxidneutral stenull i vägg- och takkonstruktion är 33 % högre jämfört med motsvarande scenario med lös cellulosaull. Scenariot med lägst klimatpåverkan, med lös cellulosaull, är cirka 13 % lägre än motsvarande glasullscenario. Det koldioxidneutrala stenullscenariot har ett liknande resultat som glasull. Skumglas har 9,5 % högre klimatpåverkan jämfört med cellplasten i grunden. När det gäller valet av isoleringsmaterial påverkar det klimatdeklarationen genom att förändra klimatpåverkan. Påverkan härstammar från en kombination av klimatpåverkan per enhet och mängden material som används i byggnaden. Mängden material beror delvis på isoleringsmaterialets värmekonduktivitet (λ-värde). Klimatdeklarationen visar en begränsad bild av en byggnads miljöpåverkan under en begränsad del av dess livscykel. Därför rekommenderar vi att ytterligare livscykelstadier och miljöindikatorer ingår i klimatdeklarationen i framtiden, för att undvika suboptimeringar och oavsiktliga problembyten.

Das 1929 fertiggestellte Jugenderholungsheim Ottendorf (Sebnitz) ist eines der interessantesten Gebäude der Weimarer Republik in Sachsen. Es wurde auf Initiative von Jugendverbänden und Gewerkschaften als erstes seiner Art speziell für erwerbstätige Jugendliche errichtet und hat somit eine hohe sozialgeschichtliche Bedeutung. Der Architekt Kurt Bärbig gilt als typischer Vertreter einer gemäßigten Moderne Dresdner Prägung und bewegte sich vielfältig im Umfeld der Sozialdemokratie und der Gewerkschaften. Sein Leben und Wirken wird in dieser Arbeit kurz vorgestellt. Im Werk Kurt Bärbigs nimmt das Heim einen bedeutenden Platz ein, da es eines seiner größten Projekte ist und die Entwurfsprinzipien des Architekten deutlich widerspiegelt. Das sind vor allem die Zweckorientierung, Naturverbundenheit und Reduktion auf das Wesentliche unter Rückbezug auf traditionelle Bauformen. Auch der sozialdemokratische Hintergrund ist hier gegeben. Während des Dritten Reiches war im Gebäude eine Schule des Bundes Deutscher Mädel (BDM) untergebracht und noch im September 1945 zog eine Parteischule der Kommunistischen Partei Deutschlands (KPD), später der Sozialistischen Einheitspartei Deutschlands (SED) ein. Das Gebäude wurde bis 1989 kontinuierlich genutzt und dabei kaum baulich verändert. Die größten Verluste sind erst nach 1989 durch den langen Leerstand zu beklagen. Aufgrund der abgeschiedenen Lage, des funktionsspezifischen Grundrisses und der Größe des Gebäudes ist es schwierig eine neue Nutzung zu finden. In der Arbeit werden die Bau­geschichte und das historische Umfeld einerseits und der heutige Bestand andererseits untersucht. Zur geschichtlichen Einordnung des Gebäudes werden historische Pläne und Fotografien ausgewertet und zeitgenössische Veröffentlichungen analysiert. Im Vergleich mit anderen Gebäuden Bärbigs werden Erkenntnisse gewonnen, welche Gestaltungsprinzipien typisch für Bärbig sind. Untersuchungen vor Ort dienen der genauen Dokumentation des heutigen Zustandes sowie der Rekonstruktion des Urzustandes. Das erfolgt in Form der detaillierten Darstellung repräsentativer Teile des Gebäudes in Aufmaß, Foto und Text. Diese Diplomarbeit bestätigt den künstlerischen und historischen Wert des Gebäudes und kann als Grundlage für künftige Planungen dienen.:1. Einleitung 2. Der Architekt Kurt Bärbig 2.1. Leben 2.2.

This thesis deals with the construction process of the apartment house Ponavia Park located in Brno. The thesis solves the individual realization phases of the main building phase. Building site equipment is designed for the projected construction process in three different variations. A technical report is also included in the building site. Critical points within the transport of materials and machines are also verified. A financial plan for the whole building is made as an summarizing time schedule for the apartment building. The sources for the financial plan are the figures taken from the Czech building objects classifications (JKSO). The summarizing time schedule is made in MS Projekt software and it’s designed as a Gantt diagram. A design of the main building machines and mechanisms was also made for the projected construction process. All of the machines were assessed for their respective required function on the building site. Also included in this thesis is a construction method for the reinforced concrete structures. The construction method deals with the realization process of waterproof concrete, reinforcement binding, formwork of the vertical and horizontal structures and also the process of concrete curing. The construction method is followed up by quality control and test plans for reinforced concrete structures, and a construction site safety plan that is made in the form of predicted main safety risks at the building site. For the noise load on the surrounding buildings a noise study is made. The study examines the intensity of noise in the protected outdoor space. This study was made in the Hluk+ software. The thesis also includes an item budget for the apartment house that was made in Build Power S software.
