A cidade sem barreiras é para todos?: avaliação das condições de deslocamento no bairro da Cidade Alta, Natal/RN

In this present work, the conditions of displacements and the behaviors of the users are evaluated, face to the physical adequacies in accessibility in the inserted area in the central quadrilateral of the Quarter of Cidade Alta, in the City of Natal/RN, space clipping established by its great meaning historical and cultural. For this reason such area was a target of an integrated actions plan during the years of 1993 and 1998, with the implantation of part of the Project CIDADE SEM BARREIRAS (City without Barriers) and, later, the implementation of the Project CIDADE PARA TODOS's proposals (City for All), having as supports the constant Brazilian norms inserted into the NB9050/1994 and in the Municipal law number 4.090/92, effective ones in the period of the interventions. Considering that the carried through actions at the time were directed to the elimination of the architectural barriers to guarantee the right to go and to come, the research received a human universe formed by all the people in situation of displacement in the central area of the interventions in the quarter of the Cidade Alta, independently of their locomotive or sensorial conditions, emphasizing the aspects most excellent how much to the accessibility of the sidewalk, as promotional of mobility, integration and urban organization, as well as of the public squares of that one quadrilateral, conceived, originally, as spaces of aggregation and social inclusion. The work appealed to the direct comment and the gotten results had been collated with the ex port facto law and technique norms, of the year of 2004, and with the legal devices contained in the Federal Decree number 5.296/2004, as way to certify the levels of efficiency of these adaptations in that it says respect to the current conditions of demanded accessibility and urban mobility

Avaliação da política pública de acessibilidade no período de 1992 a 2002 na Cidade do Natal

Este estudio tiene como objetivo evaluar los avances y límites de las políticas de accesibilidad en la ciudad de Natal. Se investigan las políticas publicas municipales de accesibilidad implantadas en los diez años subsecuentes, a partir de la sanción de la Ley Municipal de Accesibilidad Nº 4.090 del 03 de junio de 1992, que torna obligatorio la eliminación de las barreras arquitectónicas para personas con discapacidades en los lugares de circulación de peatones y edificios de uso público de la ciudad. Accesibilidad, en los proyectos de arquitectura y urbanismo es la condición esencial para asegurar a cualquier ciudadano su derecho a ir y venir con seguridad, dignidad y autonomía. Esta investigación se concentra en los barrios de: ciudad alta, Petrópolis y Ribeira, ya que esta área, en el período ya mencionado, fue la que tuvo una mayor concentración del presupuesto de inversiones públicas municipales de la ciudad de Natal, en la eliminación de barreras arquitectónicas en vías urbanas. El método adoptado fue el hipotético deductivo, a partir de la formulación de dos hipótesis de trabajo: la primera, una divergencia entre los objetivos propuestos por la Ley Nº 4.090 y sus aplicaciones prácticas y, la segunda, de las diferencias que existen en el grado de entendimiento del concepto de accesibilidad, para eso, se realizó una colecta y análisis de datos tanto empíricos como teóricos. Este estudio también retrata en el año de 2004, con el uso de la técnica de la fotografía, la realidad actual de la ciudad sirviendo como un parámetro comparativo con los proyectos asociados a la Coordinación para integración de las personas con discapacidades. Se utiliza la técnica de entrevista con especialistas en accesibilidad envueltos a lo largo del proceso de implantación de las políticas públicas en la ciudad de Natal, durante los años mencionados, obteniendo así un testimonio sobre las directrices adoptadas en ese período, con base en la legislación vigente. En la investigación documental y fotográfica se realiza una evaluación de la dimensión real de lo propuesto y ejecutado en un periodo de diez años, y se concluye sobre todos los avances y retrocesos de las políticas de gestiones públicas adoptadas con relación a la accesibilidad en la ciudad de Natal

A influência de decisões arquitetônicas na eficiência energética do Campus vol. 1/UFRN

Building design is an effective way to achieve HVAC energy consumption reduction. However, this potentiality is often neglected by architects due to the lack of references to support design decisions. This works intends to propose architectural design guidelines for energy efficiency and thermal performance of Campus/UFRN buildings. These guidelines are based on computer simulations results using the software DesignBuilder. The definition of simulation models has begun with envelope variables, partially done after a field study of thirteen buildings at UFRN/Campus. This field study indicated some basic envelope patterns that were applied in simulation models. Occupation variables were identified with temperature and energy consumption monitoring procedures and a verification of illumination and equipment power, both developed at the Campus/UFRN administration building. Three simulation models were proposed according to different design phases and decisions. The first model represents early design decisions, simulating the combination of different types of geometry with three levels of envelope thermal performance. The second model, still as a part of early design phase, analyses thermal changes between circulation halls lateral and central and office rooms, as well as the heat fluxes and monthly temperatures in each circulation hall. The third model analyses the influence of middle-design and detail design decisions on energy consumption and thermal performance. In this model, different solutions of roofs, shading devices, walls and external colors were simulated. The results of all simulation models suggest a high influence of thermal loads due to the incidence of solar radiation on windows and surfaces, which highlights the importance of window shading devices, office room orientation and absorptance of roof and walls surfaces

Influência de variáveis arquitetônicas no desempenho energético de hotéis no clima quente e úmido da cidade de Natal/RN

This master thesis aims to assess the influence of the design decisions on the energy building performance of hotels. The research is based on the integration of field study and computer simulation. Firstly, a detailed field study is carried out to identify the characteristics of hotels in Natal, Rio Grande do Norte. The items assessed are occupancies, light and equipment densities, types of air conditioning, total and monthly energy consumption, among others. A second and more comprehensive field study is carried out to identify the range of occurrence of architectural variables, with a larger number of buildings. A base case is modelled in VisualDOE, based on the first field study. Then, a first set of simulations are run to explore the sensitivity of the variables on the energy consumption. The results analyses were the base of a second set of simulations, which combined the most influential variables. The results of 384 models were assessed, and the impacts of design decisions were quantified. The study discusses tendencies and recommendations, as well as the methods advantages and disadvantages
