Item Acesso aberto (Open Access) Análise do desempenho energético de edificações: aplicação analítica do RTQ-C no Edifício do Ceamazon(Universidade Federal do Pará, 2013-03-27) OLIVEIRA, Bruno Gabriel Freitas; FRANCO, Irving Montanar; TOSTES, Maria Emília de Lima; http://lattes.cnpq.br/4197618044519148; http://lattes.cnpq.br/4254203203850909One major barrier to economic development is the growing global demand for energy and the consequent increase in the use of natural resources to provide it. Developing countries such as Brazil, showed progressive energy consumption per capita in recent years. Although the majority is from hydroelectric plants (non-polluting sources) its construction causes great environmental impact. Percentage of all energy generated, buildings are responsible for the consumption of approximately 40 % and this percentage is likely to increase by the growth of the construction industry in the country. Regarding the problem, the fight against waste, streamlining and sustainable use of energy consumed by buildings are directly linked to the reduction of environmental impact, delaying the need for increased national energy matrix. In this context is created the Technical Regulation of Quality Level Energy Efficiency Commercial Buildings, and Public Service (RTQ - C). This work consists of a critical application of the RTQ - C using a prescriptive methodology, with the focus aspects of their applicability and evaluation of thermal comfort and luminal, with the premise that the high energy performance of the building is fully achieved only when conditions are guaranteed satisfactory environmental comfort to users. Therefore it was necessary to step thorough data collection and measurements "in situ" of air temperature, radiant temperature, illuminance and relative humidity in two rooms (laboratory of comfort and classroom 2) building the Center of Excellence in Efficiency energy from Amazon - CEAMAZON subsidizing the use of the methodology proposed by Fanger (PMV and PPD), and verification of illuminance levels proposed by NBR 5413. As a result the building showed good performance, but the lack of compliance prerequisites rated with "C" level. A comfort evaluation indicated that approximately 23% of users have had on thermal comfort and the natural ventilation can be used as a strategy to climatic adaptation. Illuminance measurements indicated that only the classroom 2 possessed potential use of natural lighting during the measurement. It was concluded that, despite its importance, the RTQ - C must still pass through a process of adaptation by society and professionals involved in the energy certification of buildings and that during this period changes may be incorporated contributing to make it a effectively valid instrument for ensuring the energy efficiency of buildings in the country.Item Acesso aberto (Open Access) Avaliação através do desempenho térmico de edificação verticalizada em Belém-PA(Universidade Federal do Pará, 2013-04-01) VINAGRE, Natália Daniele de Lima; PERDIGÃO, Ana Kláudia de Almeida Viana; TOSTES, Maria Emília de Lima; http://lattes.cnpq.br/4197618044519148; http://lattes.cnpq.br/9009878908080486This dissertation studies the thermal performance of materials in a vertical facade building in the city of Belém - PA, Brazil. This work aims to contribute to the study of the thermal performance and efficiency of materials used in residential buildings of the vertical envelopment, between opaque elements, two types of materials currently very used in construction were selected, painting and ceramic coating. It also studies the influence of the height of the building on its thermal performance and energy efficiency. The study was conducted with the use of computational modeling in EnergyPlus code that evaluates the thermal performance of the building, the influence of the height at the same energy efficiency. Compares the thermal performance of the two selected materials, it was found that the ceramic coating presented building with the average internal temperature of 0.42 ° C above the temperature at the building painted, hence less thermal performance. The influence of the height of the floor did not produce a significant variation in internal temperature, because its increase, small decrease occurred in the internal temperature with thermal gradient of about -0.07 º C / m due to the wind speed is greater when more higher the pavement. It is also considered for this study as passive natural ventilation strategy for the building under study, according to the analysis of Bioclimatic chart Givoni contribute positively to the condition of the internal temperature and humidity, and consequently the user.Item Acesso aberto (Open Access) Desempenho termoenergético da utilização de telhado vegetal em edificação no clima amazônico(Universidade Federal do Pará, 2013-03-19) MARINHO, Dircirene Tavares; FRANCO, Irving Montanar; http://lattes.cnpq.br/4254203203850909; TOSTES, Maria Emília de Lima; http://lattes.cnpq.br/4197618044519148The thermoenergetic performance of all construction work stems from the decisionmaking of the initial phase, and the thermo-physical characteristics of the materials used must be considered. The thermo-physical phenomenon of inertia in the roof vegetable offers resistance to the transport of thermic charge to inside the edification, reducing the demand of the electric energy needed to its climatic conditioning. At the same time, the low albedo of the roof vegetable contributes to mitigate the effects of the heat islands in urban environments. The bioclimatic and microclimatic study needed will determine the choice of the suitable construction materials, especially regarding the protection of surfaces exposed to solar heat load. This work deals with the experimental verification of the thermoenergetic performance of a room covered with grass in a place where the vegetation is predominant, in the Guamá Science and Technology Park, Federal University of Pará Campus. The key objective was to examine the thermal response of the slab by proving mitigation of heat spikes by physical phenomenon of thermal inertia, implying favorable results of energy performance by reducing the use of active cooling. It was performed preliminary characterization of the indoor and outdoor microclimate through the obtained values of temperature and relative humidity of air, and observed the evolution of internal environmental conditions in two phases, with the slab discovered and after application of vegetation. The quantitative results showed favorable performance of the roof vegetation in the moderation of heat flow through the slab, contributing to the reduction of the temperature of indoor air and consequent energy efficiency in buildings in Amazonian climate.
