Förslag till skolbyggnad, inom ramarna för Kulturskolan Stockholm. Platsen är Älvsjö, på en fastighet som idag hör till Stockholmsmässan. Centralt i projektet är vikten av kontakt mellan skolans och stadens rum samt möjligheten att, i och genom en byggnad, stärka det publika rummet i en växande del av staden. Genom sin placering och riktning upprättar skolan möjligheter för en ny publik park, på en idag dåligt utnyttjad del av fastigheten. De olika verksamheternas lokaler samlas i tre volymer kring ett inglasat atrium, vilket utgör både skolans centrala rum och koppling mellan skola och stad. / Proposal for a school building, within the framework of Kulturskolan Stockholm. The site is Älvsjö, on a property which today belongs to the Stockholm International Fairs. A central motif in the project is the importance given to the contact between the school and the space of the city as well as the possibility that, in and through a building, strengthen the public space in a growing part of the city. Through location and direction the building establishes opportunities for a new public park, on a poorly used part of the property. The rooms of different activities are spread out in three volumes around a glassed atrium, which constitutes both the central space of the building and the connection between the school and the city.

In this degree   project, an existing proposal of a new building will contain both student   apartments, but also offices to be reviewed and improved. This building will   be established on the eastern side of Mittuniversitetet in Östersund Campus. The   effort is to try to find a better solution to the existing proposal using the   atrium as a central point for the social sustainability of the building.   Using the calculation, energy calculation and architectural program, three   proposals will be made. These proposals will then be compared to each other   to determine the best design for this building. The design that proves to be the   best has a clever solution to how an airborne corridor runs through the   entire building along with the atrium. The atrium will let in a lot of light   to the residents and will give a comfortable sense of community and desire to   interact. This design also has 30 percent lower energy consumption since the   atrium reduces heat supply during the summer. The work focuses on the student   apartments to be produced and the price from calculations does not report costs   other than the body. The offices planned in the building are reported only as   an empty space. The result shows that one of the proposals proposed is about   one million Swedish kronor cheaper to produce than the other atrium buildings   and has a 30 percent lower energy consumption then a standard house. The   thesis also shows that there is potential for the proposed proposal to be   cheaper in operation and thus earn the extra production cost that an atrium   building implies. / <p>Betyg 2018-06-05</p>

In Taiwan, the fire code is prescriptive in nature and is inappropriate to be utilized in buildings with large spaces and atria, where performance-based fire safety design method is applied. It is the goal of this dissertation to develop a design guide for this application. Through literature survey and theoretical analysis, the important parameters were induced, including: plume transport time lag, ceiling jet transport time lag, smoke entrainment rate, mechanical and natural ventilation rate. To predict smoke behavior and descending rate accurately, algebraic equations and field model were both used to calculate and compare with experimental result so that its applicability can be evaluated. Furthermore, a full-scale experiment has been conducted in the USTC campus to validate that the field model can predict the smoke behavior and descending rate accurately. Finally, the calculation models developed in this study were compiled into a guideline for fire engineering performance-based designs. Design examples were also demonstrated to explain its procedure in engineering application.

In recent years Computational Fluid Dynamics (CFD) has been extensively used in the study of the indoor environment and the thermal comfort conditions for the design of modern buildings, however, there remains the need to thoroughly evaluate the accuracy of the results given by CFD methods. In the present work, numerical investigations of the indoor thermal environment in the atria of two existing buildings and in a simple three-storey atrium building design have been undertaken using CFD techniques. The initial work involved the evaluation of various turbulence models and a radiation model used in CFD simulations for the prediction of the thermal environment in atria of different geometrical configurations in two buildings for which experimental data is available. The airflow patterns and temperature distributions were determined, under both forced and hybrid ventilation conditions and thermal comfort conditions were evaluated. The numerical predictions were compared with the available experimental measurements and, in general, good agreement was obtained between the numerical and experimental results. After the evaluation of the adequacy of available turbulence models and the validation of the accuracy of the CFD model used, a simple full-scale three-storey atrium building was modeled to explore the potential of using buoyancy-driven natural ventilation. The validated CFD model was used to determine the ventilation flow rates, airflow patterns, and temperature distributions in the building. The dynamic effect of the thermal mass of the external walls on the performance of the building was also investigated using transient CFD simulations. Atria with various geometrical configurations were studied in order to investigate the effect of atrium design changes on the air flow and temperature distributions in the simple atrium building considered. A parametric study was carried out to assess the sensitivity of the ventilation performance to the change in various geometric and solar parameters. On the basis of this parametric study, a few changes were carried out in the design of the building to examine their effect on ventilation performance. Finally, the use of night ventilation in the atrium building was explored and it was found that night ventilation can be increased by using hot water circulation in the chimney walls. / Thesis (Ph.D, Mechanical and Materials Engineering) -- Queen's University, 2012-07-22 12:57:00.947

Då Mariefred är en säsongsbetonad turistort, kändes det viktigt att i en sann stadshotellsanda bidra med publika funktioner för även invånare. Det är i stadshotellet som möten mellan invånare och gäst sker, mellan bekanta och främlingar, mellan nya och gamla ansikten. Stadshotellet ska vara öppet och tillgängligt för alla, därför var det viktigt med publika funktioner i bottenplan med siktlinjer genom tomten. Ljus, möten, siktlinjer och rörelser, som kännetecknar platser, återfinns i hotellets atrium som ger det ljus och siktlinjer som söktes. Den strikta formen har ett lekfullt uttryck i fasad för att skapa ett intressant tillägg till platsen och en kontrasterande relation till det centrala ovala rummet. Runt atriet skapades loftgångar, där platsen blev en inspiration, och klostergårdar och arabisk arkitektur, där man från balkongerna får ta del av livet på gatan var referenser. Här blir lobbyn livet som man får ta del utav uppifrån. / Hotel Atrium is built in the small town Mariefred, which is a seasonal tourist resort. The hotel offers public functions for both hotel residents and residents of Mariefred. It is in the ​​hotel that meetings between residents and guest occurs, between acquaintances and strangers , between new and old faces . The hotel is to be open and accessible to all, so it was important with public functions on the ground floor. Light, meetings, sight lines and movements , that characterizes the site, are found in the hotel's atrium that gives the sought light and sight lines. The strict form has a playful expression in the facade to create an interesting addition to the site and a contrasting relationship to the central oval room. Around the atrium there are exterior corridors to which the lobby is the central room that you can overlook from the balconies and take part of the life there, inspired by Arabic and cloister architecture.
