The purpose of this thesis is to develop a simple tool that can help designers and researchers obtain general guidelines for buildings in terms of energy usage and LCC. Another objective of this thesis is to apply this tool to residential buildings in order to understand which variables are relevant in terms of energy consumption and LCC costs. A one-story rectangular house was parameterized in terms of five variables: total glazing area; south window-to-wall ratio (WWR); east and west WWR (which are symmetrical for these two facades); insulation width; and window type (ranging from a single clear window to a double low e-clear argon filled window). A high average glazing area (30-40% of floor area) was applied in order to increase energy loads and to augment the importance of the window properties. Simulation was performed through Energy-plus (in conjunction with a code developed especially for this project) for three cities: Austin, Boston, and Seattle. A total of 1055 simulations were run for each city. The experiment showed that only the total glazing area, the E-W WWR and the window types were relevant variables. The former variable is highly correlated with total energy consumption across all cities. Another important conclusion was that each variable's effect on energy consumption worked independently of each other, as there were no considerable differences when analyzing variables individually, as opposed to analyzing them holistically. Results showed that, for Austin and Boston, it was possible to reduce energy loads by 35% and 27% respectively with a double low-e green window (as compared to a single clear window). Similarly, Seattle showed a reduction of 29% for a double low e-clear argon filled window. Nevertheless, the simplest type of window (type 1) presented the best results in terms of LCC. Therefore, we can conclude that only under a high-energy demand situation, such as with office buildings, would it be possible to obtain positive LCC results for double glazed windows. Consequently, double glazed windows will not present positive economical results in typical residential buildings. A second simulation was performed under a tighter HVAC schedule and higher internal loads. In this new scenario, the best windows were the same as with the first simulation, but maximum energy savings were higher: 50%, 34% and 35% for Austin, Boston, and Seattle, respectively. Nevertheless, when considering LCC, a double-clear window presented the best results for Austin, Boston, and Seattle, with 17%, 11%, and 5% reductions in costs respectively compared to the type 1 window. Therefore, if designers are only concerned with costs, the problem of what window to choose becomes non-trivial only for high-energy demand cases. / text

Traditional Chinese architecture is one of the major historic building types in Hong Kong. Though the documentation on traditional Chinese building structure and form is extensive, the study on the decorative components is not as abundant. The deficiency is recognized particularly in timber components due to their high vulnerability to weather and fast deterioration under natural condition. Such situation is also observed in the design of traditional Chinese timber lattices in the partition doors and windows, which are regarded as unique artistic components in the traditional Chinese architecture. The objectives of the study are set to re-discover on the design, expression and associated cultural meanings of the traditional Chinese lattices in Hong Kong and its identity in the Lingnan context. Apart from being an artistic expression with high aesthetic value, the design of the lattice patterns and features are also recognized as symbolic means for the manifestation of collective and individual aspirations and beliefs of the people. They carry the hope for fortune, peace and longevity; and the influence of traditional Chinese thinking from Confucian and Taoist can also be traced. In the traditional Lingnan architecture, Hong Kong is closely related to its context, Guangzhou style. However variations in character of the local lattice design can still be found and the identity of Hong Kong is also to be sought. A field survey on the lattice design in the graded historic Chinese architecture in Hong Kong was carried out. As there is little research reference and the sampling is limited, the objective is set to establish a procedure for the collection of data for comparative analysis. By recording the results, finding out the characters and symbolic meanings, the associated intangible cultural significance can be established. The understanding of such intangible substances will be the essence for future conservation and the conserving of authenticity will rest on the inheritance of the intangible rather than the tangible form and material. / published_or_final_version / Conservation / Master / Master of Science in Conservation

Syfte: I dagens samhälle har det blivit mer intressant att bygga med en miljö-certifiering, detta leder till att byggentreprenörer ställs inför tekniska svårigheter vid både projektering och produktion för att kraven ska uppfyllas. I denna rapport kommer svårigheterna med solvärmelast och dagsljus behandlas då de kan vara ett problem. Målet med denna rapport är att ”Belysa hur kraven på dagsljus och solvärmelast enligt miljöcertifieringssystemet Miljöbyggnad kan lösas”. Metod: Kvalitativ data samlades in via intervjuer för att få svar på frågeställningarna. Intervjuerna genomfördes i huvudsak på plats hos respektive persons företag. En hög validitet uppnåddes genom att intervjufrågorna strukturerades och hade koppling till frågeställningar och mål. Reliabiliteten stärktes genom att intervjuerna spelades in och det gick att hitta samband mellan svaren. Resultat: Kravnivåerna i Miljöbyggnad är BBR:s krav i grunden för de flesta indikatorer vilket motsvarar BRONS-nivån i Miljöbyggnad. För indikatorn dagsljus skulle SILVER vara lite bättre än BRONS och för GULD krävs datorsimuleringar samt enkätundersökning eller egendeklaration. För Indikatorn solvärmelast finns inget grundkrav i BBR då det endast står att solvärmetillskottet ska begränsas. När kravnivåerna för solvärmelast togs fram användes persienner för att ta reda på rimliga nivåer. Det kan uppstå problem med att uppfylla kraven för solvärmelast och dagsljus om arkitekten inte har tillräcklig kunskap om Miljöbyggnad. Placering av byggnader och fönster är också problematiskt eftersom byggnader inte bör ligga för nära varandra för att tillräckligt med dagsljus ska komma in i byggnaden. Mycket fönster i söderriktning kan innebära mycket solinstrålning vilket kan ge problem med att klara solvärmelasten. De lösningar som denna rapport har fått fram är att det ska finnas en dialog mellan ansvariga i projekten för att hitta pareto-optimala lösningar. Det går att sänka kravet på en indikator och höja kravet på en annan för att sammanlagt få det byggnadsbetyg som önskas. Solvärmelastens krav kan lösas med hjälp av olika sorters solskydd. Det går även att ändra fönstrets typ, storlek eller antal. Konsekvenser: Den slutsats som går att dra efter att arbetet blivit färdigställt, är att fönster påverkar indikatorerna solvärmelast och dagsljus mest. För att båda de kraven ska bli uppfyllda och få ett högt betyg, är det lämpligt att använda solskydd för att minska solvärmelasten. En rekommendation är också att beställarens arkitekt detaljberäknar indikatorerna innan förfrågningsunderlaget går ut, då det oftast är i början av byggprocessen som de större problemen kan undvikas. Begränsningar: Arbetet begränsas till att behandla indikatorerna solvärmelast och dagsljus i miljöcertifieringssystemet Miljöbyggnad. Lösningar för kravnivåerna detaljstuderas inte. Undersökningsstrategin begränsas till att bara innehålla en kvalitativ metod. Nyckelord: Dagsljus, Fönster, Miljöbyggnad, Solvärmelast / Purpose: Society has become more interested in building with an environmental certification system, which leads to that building engineers are facing technical difficulties in both planning and production to meet the requirements. This thesis addresses the technical difficulties with solar heat load and daylight in the environmental certification system Miljöbyggnad. The purpose of this thesis is to “Illustrate how the demands of daylight and solar heat load in Miljöbyggnad can be solved”. Method: Qualitative data were collected through interviews to obtain answers concering the issues. The interviews essentially took place at each person’s company. High validity was achieved by the interview questions that were structured and linked to the issues and the purpose of this thesis. To increase the reliability, interviews were recorded and it was possible to find correlations between the answers. Findings: The BRONZE level in Miljöbyggnad is basically BBR:s requirements for most of the indicators. The SILVER level for the indicator daylight were supposed to be better than BRONZE and GOLD requires simulations and pleased residents. It is not possible to find requirements for solar heat load in BBR. When the requirements for this indicator in Miljöbyggnad was set, sun-blinds were used. There may be problems in meeting the requirements for solar heat load and daylight if the architects do not have the sufficient knowledge of Miljöbyggnad. The placement of buildings and windows are also problematic because the distance between the buildings can affect daylight problems. If there are a lot of windows in the south direction, the solar gain may cause difficulty to solve the requirements for solar heat load. The solutions this thesis submits are, to have a dialogue between the involving people in the projects to find pareto-optimal solutions. It is possible to reduce the require-ments for one indicator and raise the requirements for another to get the total building-rating as required. The requirements for solar heat load can be solved by using different kinds of shading devices. It is possible to change the type of windows, size of the windows and the amounts of windows. Implications: The conclusions are that the windows affect the indicators solar heat load and daylight very much. To solve the requirements and get a high rating on both indicators, it is appropriate to use any kind of shading devices. We also recommend that the architect calculates the indicators in detail before the tender document is ready, to avoid major problems. Limitations: To limit the extensive work it was necessary to focus on the indicators solar heat load and daylight in the environmental certification system Miljöbyggnad. The solutions for the indicators levels were not studied in details. The investigation method was limited to only use qualitative interviews. Keywords: Daylight, Miljöbyggnad, Solar heat load, Windows

ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / Third generation LIDAR full-waveform (FW) based systems collect 1D FW signals of the echoes generated by laser pulses of wide bandwidth reflected at the intercepted objects to construct depth profiles along each pulse path. By emitting a series of pulses towards a scene using a predefined scanning patter, a 3D image containing spatial-depth information can be constructed. Unfortunately, acquisition of a high number of wide bandwidth pulses is necessary to achieve high depth and spatial resolutions of the scene. This implies the collection of massive amounts of data which generate problems for the storage, processing and transmission of the FW signal set. In this research, we explore the recovery of individual continuous-time FW signals at sub-Nyquist rates. The key step to achieve this is to exploit the sparsity in FW signals. Doing this allows one to sub-sample and recover FW signals at rates much lower than that implied by Shannon's theorem. Here, we describe the theoretical framework supporting recovery and present the reader with examples using real LIDAR data.

Accurate modeling of energy flows in buildings is necessary for optimization of mechanical systems, and architectural designs and components. One specific process which has been studied little is that of forced convection on the interior surfaces of window assemblies, which is present in the majority of newly constructed commercial buildings. To this end, energy flows associated with a specific Heating Ventilation and Air-Conditioning (HVAC) configuration- a floor register near a glass curtain wall with or without Venetian blinds- are analyzed experimentally and partially described with accepted theory. Natural convection at the same surface is analyzed as well, both to establish a baseline and to experimentally validate the experimental setup. A 60 cubic meter environmental chamber with precisely controlled interior conditions and electrical resistance heating panels is employed to study heat transfer at the interior surfaces of a building’s envelope. Convection heat transfer processes for various blind angles, HVAC regimes, surface temperatures, and window sizes are examined. Results show that convection at window and blind surfaces is highly dependent on blind angle, supply temperature and flow rate, moderately dependent on room-supply air temperature difference and HVAC regime, and weakly dependent on surface-supply air temperature difference. A simplified model of convection heat transfer in this particular situation is proposed for easy implementation in energy modeling software. / text

Darbe yra nagrinėjami du paplitę darbo sekų modeliai – BPMN ir Windows Workflow Foundation (WF), bei tiriama, kaip BPMN darbo sekas transformuoti į WF vykdymo modelį. BPMN ir WF yra iš esmės skirtingos kalbos ir pagrindinė transformavimo problema yra susijusi su nestruktūrizuotų ciklų eliminavimu, t.y. jų konvertavimu į proceso atžvilgiu ekvivalenčias struktūrizuotas konstrukcijas. Darbe pasirinktas žinomas algoritmas, skirtas panašioms ciklinėms konstrukcijoms transformuoti naudojant tęstinumo semantiką. Jis buvo adaptuotas BPMN modeliui. Algoritme naudojama tęstinumo semantika buvo praplėsta atsižvelgiant į BPMN ir WF modeliuose esančias konstrukcijas bei patobulinto algoritmo ypatumus. Buvo sukurti nauji algoritmai, skirti nagrinėjamai transformacijai atlikti. Transformavimo algoritmui patikrinti buvo sukurta programa, leidžianti tęstinumo semantika užrašytą BPMN darbo seką transformuoti į pavidalą, nesunkiai konvertuojamą į WF. Atliktos eksperimentinės darbo sekų transformacijos parodė, kad sukurtas algoritmas yra veiksmingas. / This paper analyzes the two most widely used workflow models – BPMN and Windows Workflow Foundation (WF). It also analyzes how a BPMN workflow can be transformed into a WF execution model. BPMN and WF represent two fundamentally different classes of languages and the basic problem is related to convertion of unstructured cycles to their structured equivalents. A known algorithm used for similar cyclic constructions transformations using continuation semantics was chosen. This algorithm was adopted for the BPMN model. The continuation semantics were extended in regards to BPMN and WF model constructions and the specifics of the improved algorithm. Finally, in order to solve the transformation, three new algorithms were created: algorithm for BPMN workflow specification with extended continuation semantics; algorithm for transforming the specification to structured model; algorithm for converting structured model specification to WF model. A specialized program, which transforms extended continuation semantics to a structured model, was written to test the transformation algorithm. Testing this program with exemplary transformations proved that the transformation algorithm was working correctly.
