Tigers (Panthera tigris tigris) can be viewed as a proxy for intact and healthy ecosystems. Their wild populations have plummeted to fewer than 3,200 individuals in the last four decades and threats to these apex predators are mounting rather than diminishing. Global conservation bodies (Global Tiger Initiative, World Wildlife Fund, Wildlife Conservation Society, Panthera etc.) have recently called for solidarity and scaling up of conservation efforts to save tigers from extinction. In South Asia, tiger habitat ranges from tropical evergreen forests, dry arid regions and sub-tropical alluvial floodplains, to temperate mixed deciduous forest. The churia habitat is relatively unstudied and is considered a young and geologically fragile mountain range in Nepal. The contribution of the churia habitat to tiger conservation has not been considered, since modern conservation started in 1970's. This study focuses on the ecology of the tiger with respect to population density, habitat use, and prey occupancy and density, in the churia habitat of Chitwan National Park. This study also includes the first assessment of genetic diversity, genetic structure, and gene flow of tigers across the Terai Arc Landscape- Nepal. The Terai Arc Landscape harbors the only remaining tiger population found across the foothills of the Himalayas in Nepal and northwest India. I used a combination of camera-trapping techniques, which have been a popular and robust method for monitoring tiger populations across the landscape, combined with a noninvasive genetic approach to gain information on tigers, thus adding new information relevant to global tiger conservation. I investigated tiger, leopard (Panthera pardus fusca), and prey densities, and predicted the tiger density across the Churia habitat in Chitwan National Park. I used a camera-trap grid with 161 locations accumulating 2,097 trap-nights in a 60 day survey period during the winter season of 2010-2011. Additionally, I used distance sampling techniques for estimating prey density in the churia habitat by walking 136 km over 81 different line transects. The team photographed 31 individual tigers and 28 individual leopards along with 25 mammalian species from a sampling area of 536 km² comprising Churia and surrounding areas. Density estimates of tigers and leopards were 2.2 (SE 0.42) tigers and 4.0 (SE 1.00) leopards per 100 km². Prey density was estimated at 62.7 prey animals per 100 km² with contributions from forest ungulates to be 47% (sambar Rusa unicolor, chital Axis axis, barking deer Muntiacus muntjak, and wild pigs Sus scrofa). Churia habitat within Chitwan National Park is capable of supporting 5.86 tigers per 100 km² based on applying models developed to predict tiger density from prey density. My density estimates from camera-traps are lower than that predicted based on prey availability, which indicates that the tiger population may be below the carrying capacity. Nonetheless, the churia habitat supports 9 to 36 tigers, increasing estimates of current population size in Chitwan National Park. Based on my finding, the Churia habitat should no longer remain ignored because it has great potential to harbor tigers. Conservation efforts should focus on reducing human disturbance to boost prey populations to potentially support higher predator numbers in Churia. I used sign surveys within a rigorous occupancy framework to estimate probability of occupancy for 5 focal prey species of the tiger (gaur Bos gaurus, sambar, chital, wild pig, and barking deer); as well as probability of tiger habitat use within 537 km² of churia habitat in Chitwan National Park. Multi-season, auto-correlation models allowed me to make seasonal (winter versus summer) inferences regarding changes in occupancy or habitat use based on covariates influencing occupancy and detection. Sambar had the greatest spatial distribution across both seasons, occupying 431-437 km² of the churia habitat, while chital had the lowest distribution, occupying only 100-158 km². The gaur population showed the most seasonal variation from 318- 413 km² of area occupied, with changes in occupancy suggesting their migration out of the lowland areas in the summer and into the churia in the winter. Wild pigs showed the opposite, moving into the churia in the summer (444 km² area occupied) and having lower occupancy in the winter (383 km²). Barking deer were widespread in both seasons (329 - 349 km²). Tiger probability of habitat use Ψ SE(Ψ) was only slightly higher in winter 0.63 (SE 0.11) than in summer 0.54 (SE 0.21), but confidence intervals overlapped and area used was very similar across seasons, from 337 - 291 km². Fine-scale variation in tiger habitat use showed that tigers intensively use certain areas more often than others across the seasons. The proportion of available habitat positively influenced occupancy for the majority of prey species and tigers. Human disturbance had a strong negative influence on the distribution of the majority of prey species but was positively related to tiger habitat use. Tigers appear to live in areas with high disturbance, thus increasing the risk of human-tiger conflict in the churia habitat. Thus, efforts to reduce human disturbance would be beneficial to reducing human wildlife conflict, enriching prey populations, and would potentially support more tigers in churia habitat of Nepal. Overall, I found high prey occupancy and tiger habitat use, suggesting that the churia is highly valuable habitat for tigers and should no longer be neglected or forgotten in tiger conservation planning. Thirdly, I assessed genetic variation, genetic structure, and gene flow of the tigers in the Terai Arc Landscape, Nepal. I opportunistically collected 770 scat samples from 4 protected areas and 5 hypothesized corridors across the Terai Arc Landscape. Historical landuse change in the Terai Arc was extracted from Anthrome data sets to relate landuse change to potential barriers and subsequent hypothesized bottleneck events in the landscape. I used standard genetic metrics (allelic diversity and heterozygosity) to estimate genetic variation in the tiger population. Using program Structure (non-spatial) and TESS (spatial), I defined the putative genetic clusters present in the landscape. Migrant analysis was carried out in Geneclass and Bayesass for estimating contemporary gene flow. I tested for a recent population bottleneck with the heterozygosity test using program Bottleneck. Of the 700 samples, 396 were positive for tiger (57% success). Using an 8 multilocus microsatellite assay, I identified 78 individual tigers. I found large scale landuse changes across the Terai Arc Landscape due to conversion of forest into agriculture in last two centuries and I identified areas of suspected barriers. I found low levels of genetic variation (expected heterozygosity = 0.61) and moderate genetic differentiation (F_ST = 0.14) across the landscape, indicative of sub-population structure and potential isolation of sub-populations. I detected three genetic clusters across the landscape consistent with three demographic tiger sub-populations occurring in Chitwan-Parsa, Bardia, and Suklaphanta protected areas. I detected 10 migrants across all study sites confirming there is still some dispersal mediated gene flow across the landscape. I found evidence of a bottleneck signature, especially around the lowland forests in the Terai, likely caused by large scale landuse change in last two centuries, which could explain the low levels of genetic variation detected at the sub-population level. These findings are highly relevant to tiger conservation indicating that efforts to protect source sites and to improve connectivity are needed to augment gene flow and genetic diversity across the landscape. Finally, I compared the abundance and density of tigers obtained using two non-invasive sampling techniques: camera-trapping and fecal DNA sampling. For cameras: I pooled the 2009 camera-trap data from the core tiger population across the lowland areas of Chitwan National Park. I sampled 359 km² of the core area with 187 camera-trap locations spending 2,821 trap-nights of effort. I obtained 264 identifiable photographs and identified a total of 41 individual tigers. For genetics, I sampled 325 km² of the core area along three spatial routes, walking a total of 1,173 km, collecting a total of 420 tiger fecal samples in 2011. I identified 36 tigers using the assay of 8 multilocus genotypes and captured them 42 times. I analyzed both data types separately for estimating density and jointly in an integrated model using both traditional, and spatial, capture-recapture frameworks. Using Program MARK and the model averaged results, my abundance estimates were 46 (SE 1.86) and 44 (SE 9.83) individuals from camera and genetic data, respectively. Density estimates (tigers per 100 km²) via traditional buffer strip methods using half of the Mean Maximum Distance Moved (½ MMDM) as the buffer surrounding survey grids, were 4.01 (SE 0.64) for camera data and 3.49 (SE 1.04) for genetic data. Spatially explicit capture recapture models resulted in lower density estimates both in the likelihood based program DENSITY at 2.55 (SE 0.59) for camera-trap data and 2.57 (SE 0.88) for genetic data, while the Bayesian based program SPACECAP estimates were 2.44 (SE 0.30) for camera-trap data and 2.23 (SE 0.46) for genetic data. Using a spatially explicit, integrated model that combines data from both cameras and genetics, density estimates were 1.47 (SD 0.20) tigers per 100 km² for camera-trap data and 1.89 (SD 0.36) tigers per 100 km² for genetic data. I found that the addition of camera-trap data improved precision in genetic capture-recapture estimates, but not visa-versa, likely due to low numbers of recaptures in the genetic data. While a non-invasive genetic approach can be used as a stand-alone capture-recapture method, it may be necessary to increase sample size to obtain more recaptures. Camera-trap data may provide a more precise estimates, but genetic data returns more information on other aspect of genetic health and connectivity. Combining data sets in an integrated modeling framework, aiding in pinpointing strengths and weaknesses in data sets, thus ultimately improving modeling inference. / Ph. D.

The central business district (C.B.D.) of Pittsburgh, Pennsylvania, "the Golden Triangle", has been for nearly sixty years with very little provision for housing. The area is topographically compact, approximately one half square mile, bounded by rivers on two of the sides and a bluff on the third side. It is the hub of the public transportation system, the convergence of the area watershed and the perceived focal point oft the region. In recent years the cultural center has also spread to the C.B.D., and there have been major rehabilitation, building and capital improvement projects. These conditions make for an environment enticing for both living and conducting business. Living Downtown: a Multiuse Complex for the Pittsburgh C.B.D. is a project that combines housing, offices, shops, parking, services and public and private open spaces. This is accomplished by considering factors such as zoning guidelines, demands for density, site conditions, egress, daylighting and sightlines. The design is inspired by Pittsburgh's vernacular hillside dwellings and the dynamics of the natural and built fabric of the site. Where a lone man may be overcome, two together can resist. A three-ply cord is not easily broken. - Eccelsiates 4:12 / Master of Architecture

Carnivore are undoubtedly among the most threatened of the mammal species in Africa because of the low density at which they occur and their large home range requirements that do not match with human propensity to develop and alter wildlife habitat. However, the degree of threat is unevenly distributed within the continent, with western and central African carnivores being the most threatened and the least studied. I estimated population size, density, and proportion of area occupied in relation to environmental factors of one medium-size (serval – Leptailurus serval) and two large carnivores (lion – Panthera leo and leopard – P. pardus) in the Niokolo Koba National Park, Senegal, West Africa, using remote camera surveys and both traditional (CR), spatially explicit capture-recapture (SECR) techniques for servals and leopards, and non-spatial (MR) and spatial mark resight (SMR) methods for lions. Lions selected optimal sites with both high tree density and prey activity; leopards occupied areas with high tree density but with less prey activity; and servals selected habitats with more dense canopy cover where leopards were absent. The presence of lions was favorable to serval presence, as we presume leopards avoid lions, although we did not have strong evidence to support it. Moreover, the half mean maximum distance moved (½ MMDM) method under CR methods appeared to overestimate leopard and serval density while full MMDM estimates were close to SECR methods density estimates. For lions, both ½ MMDM and full MMDM methods in MR framework overestimated density whereas the SMR method resulted in more reasonable estimates, especially in light of previous assessments of lion densities in West Africa.. These results are of high importance for conservation and management purposes of the imperiled Niokolo Koba carnivore community. / Master of Science

The project, a bookstore for a vacant site within the Pinch Historic District in downtown Memphis, Tennessee, develops an architectural concept of design compatibility that maintains the continuity of the existing architectural vocabulary rather than creating a literal historic replication. By using this philosophy, the design of an urban infill project that respects the history as well as the existing character of the district is developed. At the same time, the Bookstore meets the needs of the residents and visitors of the area through the provision of residential, commercial and entertainment space, thus contributing to the comprehensive revitalization of Downtown Memphis. / Master of Architecture

Architecture frames life. By framing I mean that it gives individual awareness perimeters which shape the habits of the mind while the material frame supports the life of the body. We live in the center of our awareness. Some of Wallace Stevens’ poetry explores the habits and the shape of consciousness. Consider these lines: I measure myself / Against a tall tree / I find that I am much taller / For I reach right up to the sun / With my eye / And I reach to the shore of the sea / With my ear. (1) A building is a physical entity which gives us rooms and spaces. A dualism lies in thing and void because it necessarily constricts movement as well as shaping the consciousness as one moves to and fro and as one gazes into the distance. One’s desire to do these things may be frustrated by a poor building, while a well-formed building might encourage a choreography of consciousness, a mental dance. More than any other art, architecture presses upon daily life. It reminds us of the duality of mind and body. When we can enjoy the dual nature of architecture, we become more aware of our wonderful creatureness. A pleasant opposition forms between a sensed object-building and a sensing, willing, walking, inquiring creature. Tactility and other physical qualities which are sensed contribute to vital awareness. I define architecture as the art of building that serves vital feeling over time. Exterior conditions also frame life. Literal enclosure is not required. For example, a field may form a realm, that is, an ordered place under the sky. We know where we are in a realm. In a city, the parts belong together when most of them are ordered by common elements such as a street or a market square. In the United States, most familiar cities and towns are formed by the street. Often the buildings and the street make a canyon-like room for movement and activity. The life that flows through the street creates a city and nourishes it. Commerce, symbolic activities like parades and social activities like teen-age cruising maintain street life in even the smallest and most ordinary towns. The thesis project proposes a multiuse building to pull people into a downtown center. Pulaski, Virginia is the chosen town which I will describe in the next section. I begin the design with mass conceptually carved out to frame experience. The building I designed gives Pulaski a stronger downtown edge. This makes a boundary and a turning point to reinforce its identity as a place people feel proud to call home, and to renew the firm pattern of density to guide future builders and planners. This is necessary to forestall the common disintegration of the urban edge into a straggly commercial strip with disconcerting gaps and irregularity. Consider now the specific details of one small town. / Master of Architecture

The urgent need to combat climate change is increasingly being recognized. The Paris Agreement, which aims to limit global warming, requires carbon neutrality to be achieved by the mid-21st century. Further, the energy crisis in Europe that started in 2021 highlights the importance of energy security. Universities play a crucial role in promoting the transition to neutrality. This study aims to increase universities' electricity independence to further facilitate their transition to carbon neutrality. To this end, a multi-criteria decision analysis (MCDA) method was adopted to select scenarios for increasing a campus building complex's electricity independence, considering various stakeholders' interests together with the scenarios' performances on technical, environmental, economic, and social criteria. The findings show that photovoltaic technology, despite its perceived environmental benefits, performs poorly in reducing carbon emissions when considering lifecycle emissions, particularly in countries with low-carbon electricity like Sweden. Conversely, energy conservation through behavioral changes emerges as the optimal scenario for Campus Gotland due to its economic and environmental advantages. These results challenge the common reliance on energy production technology for carbon neutrality, highlighting the greater effectiveness of demand-side measures. This work suggests that universities need a more human-centric approach to transitioning to carbon neutrality. In a broader context, this study provides universities with insights to make informed decisions to achieve carbon neutrality, emphasizing the need to consider all stakeholders. By offering a comprehensive assessment and analysis of various scenarios, this work enhances the understanding of best practices for universities aiming to lead in the global effort against climate change.

<p dir="ltr">Using historic acoustic bat data collected by the Indiana Department of Natural Resources, we constructed Bayesian occupancy models to gain insights into bat communities and populations across Indiana. Through use of informative prior distributions, we addressed two important considerations for bat conservation with our occupancy models: 1) exploring a compensatory community dynamic causing the expansion of evening bat (<i>Nycticeius humeralis</i>) populations in Indiana following the establishment of white-nose syndrome (WNS), and 2) estimating a percent decline of summertime hoary bat (<i>Lasiurus cinereus</i>) populations in Indiana due to wind energy development. We found evidence for a potential compensatory community dynamic in the evening bat system, in which losses of the Indiana bat (<i>Myotis sodalis</i>) and the little brown bat (<i>Myotis lucifugus</i>) due to WNS may be resulting in new realized niche space for evening bats, thereby contributing to a compensatory community dynamic. In our hoary bat system, we found evidence of a regional summertime decline of 8.9% annually since 2012. These findings have important conservation implications considering imperiled nature and conservation priorities for bats in North America. </p>

With declines in abundance and changing distribution of White-nose Syndrome (WNS)-affected bat species, increased reliance on acoustic monitoring is now the new "normal". As such, the ability to accurately identify individual bat species with acoustic identification programs has become increasingly important. Additionally, how bat distribution and habitat associations have changed at the local to sub-landscape scale in the post WNS environment is important to understand. The significance of these changes, relative to bat activity, may be based on the species-specific susceptibility to WNS. We used data collected from Fort Drum Military Installation, New York from the summers of 2003-2017 to analyze the accuracy of acoustic software programs, and assess the changes in relative bat activity, occupancy, and distribution induced by WNS. Our results indicate that continued acoustic monitoring of bat species, such as the little brown bat (Myotis lucifugus) in the Northeast, to assess ongoing temporal and spatial changes, habitat associations, and as a guide to direct future mist-netting should rely more on relative activity as the metric of choice. Furthermore, the continuous spread of WNS across North America will have strong negative effects on bat populations and communities, this study points to how individual species (both impacted and non-impacted) will respond to WNS. We believe that our results can help users choose automated software and MLE thresholds more appropriate for their needs to accurately address potential changes in communities of bat species due to impacts of WNS or other factors. / MS / White-nose Syndrome (WNS), was first documented in the United States in 2006. The fungus that causes WNS grows on the exposed tissues of hibernating bats and causes abnormal frequent arousal and activity through winter that consequently leads to premature loss of critical fat reserves and disruption of water balance. To date millions of cave-hibernating bats have been killed by White-nose Syndrome. With declines in abundance and changing distribution of WNS-affected bat species, the ability to accurately identify individual bat species with acoustic identification programs has become increasingly important. Additionally, how bat distribution and habitat associations have changed at the local to sub-landscape scale in the post WNS environment is important to understand. We used data collected from Fort Drum Military Installation, New York from the summers of 2003-2017 to analyze the accuracy of acoustic software programs, and assess the changes in relative bat activity, occupancy, and distribution induced by WNS. Looking at this disease through time is important because it allows us to predict how bat communities in areas where the disease has not yet reached may change if there is an outbreak. Our results indicate that continued acoustic monitoring of bat species in the Northeast, to assess ongoing temporal and spatial changes, habitat associations, and as a guide to direct future mist-netting should rely more on relative activity as the metric of choice. This information can be directly applied with on the ground management for bats, which can buffer against the additional consequences this disease has on bat populations.

台灣已於1993年邁入高齡化社會，因社會結構及傳統觀念的改變，高齡者逐漸重視自己退休後的個人生活，而選擇獨自或與配偶一起入住專為高齡者規劃設計之老人住宅的比例也逐年攀升；為有效促進高齡者從事對身心有益的休閒及社交活動，老人住宅應該配合提供安全、適當的日常活動公共空間及設施來支持。因此，老人住宅的公共空間規劃與設計就顯得相當重要。究竟老人住宅之公共空間是否可以真正滿足高齡者的使用需求？是否可促使高齡者積極使用？正是目前規劃、興建或改善老人住宅的重要課題之一，亦為本研究所欲探討之主要動機。 本研究運用資料調查、實地觀察、深入訪談及問卷調查等多元調查與評估方法，並選擇擁有多樣室內、室外之公共設施及共用空間的「長庚養生文化村」作為研究案例，分別針對「公共服務設施」、「室內休閒設施」、「戶外活動空間」及「共用服務空間」等4類公共空間進行使用及規劃等議題之探討，即藉由老人住宅用後評估，深入探討高齡者對於所居住的老人住宅現有公共空間規劃的滿意程度，探究高齡者對於老人住宅公共空間規劃設計之真實反應與感受；並依據評估分析成果，提出老人住宅公共空間之規劃原則建議，以供未來興建高齡者安居住宅之公共空間規劃參考。本研究結果及建議如下： 一、高齡者對公共空間需求滿意度以戶外森林步道及健康中心最高，以健康為主軸的休閒性設施仍為未來規劃重點。 二、老人住宅公共空間滿意度與「教育程度」、「身體狀況」、「子女探訪情形」等三項因素有關。 三、目前老人住宅公共空間議題，關心度低，容易被忽視及犧牲。 四、老人住宅公共空間規劃設計之主要議題包括： （一）餐廳為入住老人住宅之高齡者社交活動的重要空間，也是假日與探訪家人聚餐的重要場所，而餐廳的寬敞、舒適程度，及社交機會之提供，是高齡者關心的議題之一。 （二）設置報紙的交誼廳使用率較高，而設有書報的交誼廳，其照明及管理等議題必須加強考慮。 （三）中央式的走廊，因為通風及採光較不佳，降低了高齡者的社交機會。 （四）活動量大的活動休閒空間（如籃球場、桌球室等）僅能供探訪家人使用，效用不大，未符合高齡者需求。 五、規劃適合每一位高齡者的居住空間，建議朝向「通用設計原則」來進行規劃設計。 六、老人住宅基本生活之公共空間（如交誼室、洗衣室等），應配合生活單元作可及性高的簇群式配置，以增加高齡者使用機會；至於提供全部高齡者共同使用之休閒空間（如學習教室、娛樂室、會議室等），建議集中配置，以方便管理。 / Taiwanese society has become an aging society since 1993. Due to changes in societal structure and traditional concepts, phenomenon such as aging people started to emphasize more on their personal life after retirement and increasing ratio of aging population, either single or with domestic partner, move into specially designed retirement apartment have brought up to attention. In order to effectively encourage aging resident to exercise beneficial recreation and socialization activities, safe and proper common activity areas in retirement apartments are necessary and thus, the design and planning of the common recreation areas has become an essential issue. Questions regarding whether the retirement apartments will fully satisfy the needs of their aging resident and whether the aging residents actively utilizing those facilities are two of the most essential regards for planning, building, and improving retirement apartments; this is also the motivation for conducting this research. Our research focuses four main issues regarding as utilization and planning of public area such as “public service facility”, “in-door recreation facility”, “out-door activity space”, and “shared service space” in Chang Gung Health and Culture Village which possesses varieties of in-door and out-door public facilities and public areas; the research itself is conducted by data investigation, on-site observation, detailed interview, and paper-based survey to insightfully investigate the degree of satisfaction of aging residents toward existing planning of shared area and real feeling and reaction toward existing planning of public area. Suggestions for planning of shared areas, as results from analysis of conducted surveys, are provided for the reference of future planning of shared areas in aging resident village. The suggestions are as followed: 1.Out-door forest trails and healthcare centers are the two types of facilities that are listed among the highest degree of satisfaction by aging people. Health-oriented recreation facilities are still regarded as the most essential element in future planning of retirement apartment construction. 2.The degree of satisfaction in retirement apartment is directly associated to three factors which include “degree of education received”, “physical condition of the aging person”, and “the frequency of family visits.” 3.The current issues for public area in retirement apartments are low degree of attention and easily neglected or sacrificed. 4.Issues regarding the planning of public areas in retirement apartments includes: A.Cafeteria is one of the most important socializing space for aging residents in retirement apartment and an important space for family visits. Degree of comfortableness and spaciousness of cafeteria and whether the cafeteria offers socializing opportunities to aging residents are the two main concerns of aging residents. B.Utilization degrees in lobbies that provide newspaper are higher than lobbies that do not provide newspaper. The lighting and management of such lobbies are needed to be emphasized. C.Socialization opportunities decrease due to the facts that lighting and aeration in central hallway are not quite satisfactory. D.Recreation areas that involve physical activities such as basketball and table tennis are only for family members that visit the aging resident and are not satisfactory to the demand of aging residents. 5.Plan the resident area for each aging resident by utilizing principles of universal design is suggested. 6.The public space of retirement apartment for daily live, such as social room or laundering room, shall be disposed fitting Cluster of Living Style for accessibility to increase the using of the elderly; As for the common space of leisure for all elderly, Such as learning room, recreation room, conference room, it is suggested be allocated together for the convenience of management.

Habitar ambientes dimensionados a partir de estudos antropométricos e Avaliações Pós-Ocupação (APOs) dos aspectos funcionais é conseqüência de processos de projeto arquitetônico a serem consolidados. A tecnologia tem permitido obter um maior controle sobre todas as fases da produção de edificações, sendo a fase de pré-projeto decisiva para o efetivo sucesso de um empreendimento. A presente pesquisa objetiva o desenvolvimento de um roteiro para a elaboração de um programa computacional de Projeto e Desenho Arquitetônico Auxiliado por Computador (CAADD - Computer Aided Architectural Design and Drafting) que contribua para o trabalho do arquiteto nas análises geométricas de dimensionamento funcional de edificações habitacionais sociais multi-familiares, no momento do pré-projeto, considerando as especificidades do conjunto de variáveis envolvidas em cada situação de projeto. Ao escolher as alternativas de composição de Programa de Necessidades no sistema, este geraria maquetes eletrônicas (modelo digital) a partir dos parâmetros definidos no próprio programa. Os volumes abstraídos em meio digital são tratados genericamente no sistema como objetos volumétricos (mobiliário, eletrodomésticos, peças sanitárias, esquadrias, estrutura, vedação). A tecnologia de representação gráfica digital escolhida foi o padrão aberto para a distribuição de conteúdo tridimensional denominado X3D. A montagem do roteiro contempla conceitos de Computação Gráfica e de Geometria Computacional, aplicando critérios para arranjo físico de ambientes da habitação, relação entre ambientes, distribuição de unidades habitacionais (apartamentos) e análises de locação da edificação no sítio urbano. Utilizam-se como referências dimensionais resultados de APOs (classificadas como dados dinâmicos, os quais se alteram com maior freqüência no tempo) e legislação e normas vigentes (classificados como dados estáveis, os quais se alteram com menor freqüência no tempo), visando melhorias espaciais e manutenção contínua da abordagem do projeto e desenho arquitetônico funcional nos novos projetos habitacionais. / The possibility of living in environments that have been sized on the basis of anthropometric studies and post-occupancy evaluations (POEs) of the functionality of buildings is the consequence of architectural design processes yet to be consolidated. This technology has enabled greater control over all stages in the construction of buildings, the pre-design stage being decisive for the success of an enterprise. The objective of the present study is to develop guidelines for designing a computer program for architectural designing and drafting (CAADD-Computer Aided Architectural Design and Drafting) that will serve as an aid to architects in terms of geometrical analyses of the functional dimensions of low-income housing during the pre-design stage, considering the specific aspects of the variables involved in each design. By choosing alternatives for programming the software, the system is set up to enable designers to generate digital models based on standards defined in the program itself. The digitally extracted volumes are treated generically in the system as volumetric objects (furniture, appliances, plumbing fixtures, door and window frames, structures, waterproofing and others). The open standard for distributing tridimensional contents, known as X3D, was chosen as the technology for digital graphic representation. The guidelines take into account concepts for graphic computing and computational geometry and apply criteria for the physical arrangement of living environments, relationships among environments, distribution of the apartments and analyses of the location of the buildings in their urban context. Dimensional references are used to establish these guidelines, including the results of POEs (classifying the data that changes most often over time as \"dynamic\"). Other factors that must be taken into consideration are the local laws, norms and regulations (classified as \"stable\" data, which change less often over time). The objective is to develop spatial improvements and continuous feedback of the approach of the design and functional architectural drafting in new housing designs.
