In the last decades, the rehabilitation market has become increasingly significant in France. In particular, the renovation of university sites and hospitals from the 1970s, which is a fast growing segment of the French construction market. In parallel, the office and residential buildings construction sector is becoming a lot more environmentally friendly, with more efficient buildings and more advanced sustainable systems such as better design and implementation of renewable energy sources. This Master thesis, carried out in France with the company Elioth, focuses exclusively on the renovation market. The goal of this thesis is to determine a model that delivers forecast consumption for an existing building. The efforts during this Master Thesis project have been put to one typology of building in situation of an energetic performance commitment at Elioth. Rehabilitation projects on university campuses are the most ongoing and urgent demand from the company. So university as a based building has been chosen to support the thesis. The result of this Master thesis is a practical supporting protocol along with an operative tool named “Estim’ELIOTH”. It enables environmental engineers to define the data in their possession in order to use the tool to determine the energy consumption of the building studied. This feature aims to provide information for energy performance commitment management in the early stages of the design. Nowadays, this is essential for renovation projects in France.

Building energy efficiency is progressively becoming a crucial topic in the architecture, engineering, and construction (AEC) sector. Energy management tools have been developed to promise appropriate energy savings. Building energy simulation (BES) is a tool mainly used to analyze and compare the energy consumption of various design/operation scenarios, while building automation systems (BAS) works as another energy management tool to monitor, measure and collect operational data, all in an effort to optimize energy consumption. By integrating the energy simulated data and actual operational data, the accuracy of a building energy model can be increased while the calibrated energy model can be applied as a benchmark for guiding the operational strategies. This research predicted that building information modeling (BIM) would link BES and BAS by acting as a visual model and a database throughout the lifecycle of a building. The intent of the research was to use BIM to document energy-related information and to allow its exchange between BES and BAS. Thus, the energy-related data exchange process would be simplified, and the productive efficiency of facility management processes would increase. A systematic literature review has been conducted in investigating the most popular used data formats and data exchange methods for the integration of BIM/BES and BAS, the results showed the industry foundation classes (IFC) was the most common choice for BIM tools mainly and database is a key solution for managing huge actual operational datasets, which was a reference for the next step in research. Then a BIM-based framework was proposed to supporting the data exchange process among BIM/BES/BAS. 4 modules including BIM Module, Operational Data Module, Energy Simulation Module and Analysis and Visualization Module with an interface were designed in the framework to document energy-related information and to allow its exchange between BES and BAS. A prototype of the framework was developed as a platform and a case study of an entire office suite was conducted using the platform to validate this framework. The results showed that the proposed framework enables automated or semi-automated multiple-model development and data analytics processes. In addition, the research explored how BIM can enhance the application of energy modeling during building operation processes as a means to improve overall energy performance and facility management productivity. / Doctor of Philosophy / Building energy efficiency is progressively becoming a crucial topic in the architecture, engineering, and construction (AEC) sector, promising appropriate energy savings can be achieved over the life cycle of buildings through proper design, construction, and operation. Energy management tools have been developed towards this end. Building energy simulation (BES) is a tool mainly used to analyze and compare the energy consumption of various design/operation scenarios. These instances include the selection of both new and retrofit designs and for building codes, building commissioning, and real-time optimal control, among others. The main challenge surrounding BES is the discrepancy between quantitative results and actual performance data. Building automation systems (BAS), or a part of BAS which is often referred to as building energy management systems (BEMS), works as another energy management tool to monitor, measure and collect operational data, all in an effort to optimize energy consumption. The key disadvantage to the more general tool of BAS in energy management is that the data sets collected by BAS are typically too large to be analyzed effectively. One potential solution to the lack of effective energy management analysis may lie in the integration of BES and BAS. Actual operational data can be compared with simulation results in assessing the accuracy of an energy model while the energy model can be applied as a benchmark for evaluating the actual energy consumption and optimizing control strategies. The presented research predicted that building information modeling (BIM) would link BES and BAS by acting as a visual model and a database throughout the lifecycle of a building. The intent of the research was to use BIM to document energy-related information and to allow its exchange between BES and BAS. Thus, the energy-related data exchange process would be simplified, and the productive efficiency of facility management processes would increase. More specifically, this research posits the framework of integrating BIM, BES, and BAS to produce a seamless and real-time energy-related information exchange system. The proposed framework enables automated or semi-automated multiple-model development and data analytics processes. In addition, the research explored how BIM can enhance the application of energy modeling during building operation processes as a means to improve overall energy performance and facility management productivity.

Through the exploration of designing a small residential building along side a three-story mixed-use center for individuals and families newly diagnosed with diabetes, I studied a variety of ways to architecturally embrace the essence of balance. Throughout this thesis the quests of understanding "balance" accelerated and complicated most of the decision making. Architecturally, this thesis explored the balance between the public city and private residence, between historical architecture and the proposal of new construction, and the balance between solid voids and the path of circulation. The pursuit of balance was even examines at the detail level; how do you find a balance at the integration of two of more materials. Objects and visual situations are most stimulating when they achieve an appropriate balance. / Master of Architecture

In this thesis, I explored approaches to convert an office building to a residential building considering social activities and new normal. Focused, productive work is likely carried out a home, at times which best suit individual lifestyles, while collaborative and socially interactive activities bring people together in a variety of spaces. We saw this leading to the need for resilient homes, homes with the adaptability to support a range of activities throughout people's days. Homes need to provide spaces for exercise, entertainment, digital collaboration, connection, and focus (without becoming isolated), alongside the traditional activities of eating, sleeping, and washing. / Master of Architecture / Architecture finds new meaning or loses the old ones, depending on what is happening in the world and how human lives changing. Since pandemic hit in 2020, life has been abnormal in most aspects. Quarantine, remote working, and online activities are some of the new normal that inevitably became a part of human lifestyle. Even after the quarantine, the Internet-based communications is continued, and many office buildings left vacant while the need of more spaces for different activities felt in the residential buildings. Converting office buildings into housing is new 'normal' in this post pandemic era.

Problemet vid ROT-arbete är att många delar av upprustningen kan orsaka tidsfördröjning, vilket är extra känsligt för projekt under stor tidspress. Om det handlar om att återställa en byggnad som inhyser en verksamhet, så arbetas det mot en mycket större tidspress än vid återställande av bostadshus. Förseningar är något som man varken har tid eller råd med. Det gäller att få igång verksamheten så fort som möjligt, dels för att inte ägarna ska förlora inkomst och dels för att försäkringsbolaget vill betala ut rätt försäkringspengar. Examensarbetet visar de viktigaste momenten i både teori och praktik. Det har gjorts en litteraturstudie inom ämnet för att få en bred kunskapsbas. En intervju har också genomförts med en i dag erfaren projektledare, som pekat på de viktigaste arbetsuppgifterna för en projektledare i ett ROT-projekt. Syftet är att finna de faktorer som kan försena ett ROT-projekt och precisera dessa i en checklista för att projektledaren ska kunna upprätta en säkrare tidsplanering. Det är viktigt att projektledaren, trots det pressade tidsschemat, genomför riskhanteringsmetoden vid ROT-arbeten. En planerare som för första gången ska analysera risker med ett ROT-arbete bör gå efter riskhanteringsmallen för att undvika att förbise viktiga riskmoment och hanteringsmetoder. Vissa av projektledarens viktiga åtaganden beskrivs inte i teorin, vilket gör det svårt för en projektledare utan tidigare erfarenhet från yrket. Därför är denna studie användbar, då den belyser både teori och praktik.
