Studied area is located in a quiet street in Palm Brno. Land is mostly wooded park, dominated the land, the villa of 30 years. The idea was to create a concept that keeps dominating the villa and does not interfere with surrounding buildings. New building fills a gap in the street and is stretched to the rear of the property. Loosely on her property for recreation and leisure. The building is partially embedded in the slope, the existing facilities are tennis court. Below ground there are located ground parking.

The newly built office building in an exclusive residential suburb of Brno is a worthy partner to the villa from the thirties of the last century. The layout is based on the contrast of the surrounding built-up area. Its sharp and clean lines are dissimilar from the round forms of the neighbouring villa. The minimalist concept frees of the classical façade articulation. However it most respects other neighbouring buildings with its dimension arrangement.

This thesis delves into the transformative potential of office buildings, which have traditionally functioned as private, employee-centric spaces. It confronts the challenge of reviving inactive urban areas by advocating for the reconfiguration of certain segments of these buildings into accessible public spaces. The research proposes an in-between typology, redefining office buildings into the community fabric while preserving essential privacy and security for business operations. By employing architectural strategies that enhance welcoming atmospheres, and helps bring in the street energy into the building. It advocates for the creation of vibrant, interactive zones where individuals can gather, socialize, and celebrate cultural and day-to-day events, facilitating access to the interesting parts of the building. This approach not only promises to elevate public engagement but also aid potential economic benefits for businesses by transforming underutilized spaces into active community hubs. / Master of Architecture / This thesis investigates how we can transform office buildings from private, employee-only areas into active parts of the city that welcome everyone. How parts of these buildings could be opened up to the public to help breathe new life into areas of the city that are otherwise quiet and underused. Redesigning of office buildings so that they not only serve their traditional business purposes but also become integrated parts of the urban community. This doesn't mean compromising the privacy and security necessary for business operations, instead, it's about finding a balance where both can coexist. The thesis suggests architectural designs that make these buildings feel open and inviting. For instance, incorporating elements that draw in the lively vibe from the street outside can make entering the building a more appealing experience. The goal is to create spaces within these office buildings where people can come together not just for work but also to socialize, participate in cultural events, or simply enjoy their day. This could mean designing certain floors or areas that are open to the public, with cafes, exhibition spaces, or areas for performances that attract both office workers and the general public. Making these changes could significantly enhance public interaction in these spaces, turning them into vibrant community hubs rather than just workplaces. This can increase foot traffic, which not only adds to the building's vibrancy but can also provide economic benefits. Shops, cafes, and cultural venues within these buildings could see higher customer volumes, and the businesses housed there may enjoy greater visibility and engagement from the community.

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.

O crescimento industrial, comercial e de serviços traz para as sociedades mais evoluídas uma série de benefícios, como o desenvolvimento econômico e o crescimento populacional, aliados a maiores oportunidades de emprego e renda. Entretanto, pela falta de uma consciência mais apurada sobre os possíveis impactos negativos de ritmo acelerado de crescimento, acaba-se verificando uma série de problemas sociais e, sobretudo, ambientais. Em razão disso, nos últimos anos, constata-se a preocupação de alguns setores da sociedade na busca do desenvolvimento fundamentado em práticas mais sustentáveis. Isso não tem sido diferente no setor da construção civil. A preocupação com a sustentabilidade nos empreendimentos é tema e foco de diversos eventos, tanto no meio acadêmico, como no profissional e governamental. Particularmente, o segmento de mercado de EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS tem sido alvo de pressão para o uso de práticas mais sustentáveis em todo o seu ciclo de vida, desde sua concepção, projeto, implantação e operação até a sua revitalização. Para aferir a sustentabilidade dos EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS, muitas empresas do setor buscam certificações de origem estrangeira, que possuem certas limitações em sua aplicabilidade no Brasil, as quais são discutidas neste trabalho. Neste contexto, esta tese visa à construção da CERTIFICAÇÃO DA SUSTENTABILIDADE DE EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS no Brasil, que é oportuna e necessária para tratar das condições de contorno e de realidade nacional. Para isso, foram realizados: [i] levantamento do estado da arte deste tema; [ii] construção da MATRIZ DE ATRIBUTOS para a avaliação da sustentabilidade dos EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS; [iii] entrevistas com formadores de opinião deste segmento do mercado imobiliário; [iv] visitas em EDIFÍCIOS DE ESCRITÓRIOS CORPORATIVOS relevantes para as arbitragens iniciais; [v] a construção dos procedimentos, regras e rotina, com testes de validação e calibragem do SISTEMA PARA CLASSIFICAÇÃO. / The industrial, commercial and service growth provided the developed societies with many benefits, such as the economic development and the population increase, along with greater work and income opportunities. However, due to the lack of a better understanding about any possible negative impacts the fast growth pace created many social and environmental issues. Because of that, in the last years, there has been a greater concern of a few society groups aiming at using more sustainable practices. The civil construction segment has been no different. The concern with sustainability is a primary topic of several corporate events, either academically, professionally and governmentally. Especially the Office Buildings market has been a target for the use of more sustainable practices, both in its design, project, implementation, operation and revitalization. In order to measure the sustainability of Office Buildings, many companies seek for foreign certificates, with specific limitations as for their use in Brazil, which will be detailed in this paper. In this context, this Thesis aims at designing a system for the SUSTAINABILITY CERTIFICATE OF OFFICES BUILDINGS in Brazil, convenient and needed to treat the national conditions. That required: [i] a bibliographical research on the topic; [ii] building the ATTRIBUTE MATRIX to evaluate the sustainability of OFFICES BUILDINGS; [iii] interviews with influent people in the real estate segment; [iv] visits to relevant OFFICES BUILDINGS for the initial arbitrations; [v] setting the procedures, rules and routine, with validation tests.

Most scientists agree that the earth's temperature continues to rise. The heat gain is more pronounced in urban areas due to a phenomenon known as the urban heat island effect. The urban heat island effect is a seemingly inevitable result of urban development, which has far reaching consequences. With energy costs skyrocketing and the destruction of the environment at risk, urban structures and buildings must do more to make our urban settings more environmentally friendly. So far, there are two well known ways to combat these effects. First, the heat island can be slightly be negated by adding well-watered vegetation to a site. Second, is to use building materials and systems that reflect the light, thus increasing the overall albedo of an urban area. Albedo is the ratio of the light energy is reflected compared that of which is absorbed. The combinations of these two practices are some of the components in green architecture. To Date, the United States has been slow to adopt policies that reduce the urban heat gain. Likewise, developers have been hesitant to construct these buildings due to implied cost and lack of knowledge. The intent of this project is to show that there are many strategies and design features that can be implemented to combat the urban heat island effect, even in the most challenging locations. The project will also employ green architecture methods in a commercial sector that has yet to fully grasp the potential to reduce heat gain and lower the urban heat island effects. To aid in the research, this project will detail buildings that are already addressing the urban heat island. The document will identify the most effective and inexpensive ways to solve this problem. It will also describe what can be done to reduce heat waste generated by lighting and cooling. In doing so, the information garnered should lead to design strategies that new buildings can utilize to reduce the urban heat island effect.

This research seeks to find a design solution for reducing the energy usage in high-rise office buildings in Singapore. There are numerous methods and techniques that could be employed to achieve the purpose of designing energy efficient buildings. The Thesis explores the viability of double-skin fa??ades (DSF) to provide natural ventilation as an energy efficient solution for office buildings in hot and humid environment by using computational fluid dynamic (CFD) simulations and case study methodologies. CFD simulations were used to examine various types of DSF used in office buildings and the behaviour of airflow and thermal transfer through the DSF; the internal thermal comfort levels of each office spaces were analyzed and compared; and an optimization methodology was developed to explore the best DSF configuration to be used in high-rise office buildings in the tropics. The correlation between the fa??ade configurations, the thermal comfort parameters, and the internal office space energy consumption through the DSF is studied and presented. The research outcome of the Thesis has found that significant energy saving is possible if natural ventilation strategies could be exploited with the use of DSF. A prototype DSF configuration which will be best suited for the tropical environment in terms of its energy efficiency through cross ventilation strategy is proposed in this Thesis. A series of comprehensive and user-friendly nomograms for design optimization in selecting the most appropriate double-skin fa??ade configurations with considerations of various orientations for the use in high-rise office buildings in the tropics were also presented.

The modern society uses more and more electronic devices needed to being able to function together. This put higher demands on the electrical grid together with that the typical load have changed from the past. Therefore utility companies are obliged to keep the voltage within certain limits for this to function. What exact these limits have been have not always been clear since they have not been gathered in one single document.  This thesis is a cooperation with Kraftringen who also has been the initiator. Kraftringen would like to become more proactive in their work regarding electric power quality. For becoming more proactive continuously measurements have to be done but the locations have to be carefully selected in the beginning to get a wider perspective of the grid. Energy markets inspectorate (EI) is supervisory of the electric power quality in Sweden and since 2011 they have published a code of statutes (EIFS 2011:2 later 2013:1) intended to summarize limits on voltage. Some of the electrical power quality aspects are not mentioned in EIFS 2013:1 and standards have to be used to find limited values. Flicker and interharmonics are not mentioned in EIFS 2013:1 and for values on flicker the standard SS-EN 50160 has to be used and for interharmonics the standard SS-EN 61000-2-2 state limit values. Besides all this there are standards with stricter limits than EIFS 2013:1 e.g. for total harmonic distortion on voltage were SS-EN 61000-2-2 suggest 6 % instead of 8 %. Three different field studies have been conducted in order to get some perception of the present situation regarding electric power quality. Two measurements were conducted on a typical office building because they represents a large part of the typical load in Lund. The third measurement was conducted on a substation in a rural area to get a perception of the situation outside urban areas.  These measurements shown that the overall electric power quality was within given limits according to EIFS 2013:1 and different standards. However, conducted measurements shown some interesting results. Both the typical office buildings have a slightly capacitive power factor which results in that the voltage inside the building is going to be slightly higher than at the substation. Since the voltage level at the measured urban substation was above nominal voltage level with about 2-5 % this could be problematic. Another eventual problem with a load with a capacitive power factor is resonance with the inductive parts of the grid like transformers leading to magnified harmonic levels. It is suggested that Kraftringen expand their number of permanent electric power quality measurement locations to get a better overview of the present situation. The best suited locations to start with are such that have received complaints earlier, preferably measured on the low voltage side of the transformer for also register the amount of zero sequence harmonics. Next step in the measurement expansion would be substations known to be under higher load than others or substations with a PEN-conductor in a smaller area than the phase conductors, supplying a typical office load with high amounts of third harmonics and unbalance. From this it would be appropriate to spread out the measurement locations geographically to better get to know the grids behaviour.

In this study, the energy conservation potential of selected retrofitting interventions on an office building were investigated, on the basis of which some rational strategies for the improvement of building envelopes in terms of energy, environment and comfort design were proposed. Examined were various measures on envelope constructions that can be retrofitted to existing buildings. By using simulation techniques, the effectiveness of such measures in reducing energy consumption and environmental threat were also assessed. Effects of glazing types, effect of insulation and thermal mass were analyzed as energy efficient retrofit measures to the Engineering Building (MM building) situated on Middle East Technical University Campus, Ankara. The Energy-10 computer program was used for the modeling and simulation of the energy flows through the envelope to examine measures for reducing thermal load. Within this framework, the energy conservation potential of single and combined retrofitting actions was investigated. Based on results from the evaluation model, it was found that a saving of 161.20 MWh in the annual heating load could result, depending on the glazing type. The evaluation showed that thermal insulation is the most effective factor in thermal performance when placed as an exterior layer on walls. The study showed thermal mass has significant impact on increasing the duration, where highest temperatures were achieved, under passive mode. The study also revealed that applying a combination of retrofitting measures which responded to the challenges and opportunities presented by different fa&ccedil / ade orientations, a saving of 52.41% can be achieved in annual heating energy use in case study building.
