Sendo assim, o trabalho a seguir trata-se do anteprojeto arquitet?nico de um novo ambulat?rio para o Hospital Universit?rio Onofre Lopes com ?nfase na aplica??o de estrat?gias passivas de ventila??o natural com objetivo de promover um maior n?mero de trocas de ar no interior dos ambientes. O pr?dio possui uma ?rea constru?da de 31.998,97m?, distribu?dos ao longo de 10 pavimentos, sendo um t?rreo e mais 06 andares superiores, al?m de tr?s subsolos, a ser edificado na ?rea 01 do Campus Biom?dico da Sa?de, localizado no Bairro de Petr?polis. A ado??o do partido arquitet?nico levou em considera??o uma s?rie de condicionantes tais como topografia do terreno, dire??o e velocidade dos ventos predominantes, sistema construtivo, al?m daquelas de ordem normativas, com destaque para NBR-15220 e C?digo de Combate a Inc?ndio. Os procedimentos metodol?gicos adotados envolveram o c?lculo do fluxo e n?mero de trocas de ar por hora nas salas de espera, consult?rios e mecanoterapia/termoterapia que foram registrados em mem?rias de c?lculo, para o qual foi necess?rio o conhecimento das velocidades dos ventos no interior dos ambientes analisados, de dados obtidos na base de dados do Laborat?rio de Conforto Ambiental da Universidade Federal do Rio Grande do Norte, al?m da utiliza??o de refer?ncias bibliogr?ficas sobre o tema do conforto t?rmico. Os resultados obtidos mostram que as estrat?gias de ventila??o cruzada aplicadas no projeto, tais como utiliza??o de sheds na cobertura para captar o vento em dire??o a po?os de ventila??o, aliados a ?trios internos e loca??o de aberturas em pontos opostos com diferentes coeficientes de press?o, dimensionadas e sombreadas adequadamente, provocam um aumento no fluxo e n?mero de trocas de ar por hora no interior dos ambientes quando comparado ? ventila??o unilateral. Dessa forma permite-se que cada um seja ocupado por uma maior quantidade de pessoas, requisito esse importante para a funcionalidade do pr?dio, j? que o hospital trata-se de uma institui??o de ensino. Dessa forma, potencializa-se o uso da ventila??o natural e cria-se as condi??es para minimizar o consumo de ar condicionado, que contribui para o planejamento de uma arquitetura com mais efici?ncia energ?tica. / Some sites in the city of Natal / RN have pleasant conditions of natural ventilation, however, the built buildings rely heavily on air conditioning systems for air renovation, often the result of inadequate planning that does not prioritize aspects of environmental comfort. Therefore, the following work deals with the architectural design of a new outpatient clinic for the University Hospital Onofre Lopes, with emphasis on the application of passive strategies of natural ventilation with the objective of promoting a greater number of air changes within the environments. The building has a built area of 31,998.97m?, distributed over 10 floors, one ground floor and a further six floors, in addition to three basements, to be built in area 01 of the Biomedical Health Campus, located in the Petropolis District. The adoption of the architectural party took into account a series of constraints such as topography of the terrain, direction and speed of prevailing winds, construction system, besides those of normative order, especially NBR-15220 and Fire Code. The methodological procedures adopted involved calculating the flow and number of air changes per hour in the waiting rooms, clinics and mechanotherapy / thermotherapy that were recorded in calculation memories, for which it was necessary to know the velocities of the winds inside the environments analyzed, from data obtained from the Laboratory of Environmental Comfort of the Federal University of Rio Grande do Norte, in addition to the use of bibliographical references on the topic of thermal comfort. The results show that the cross ventilation strategies applied in the design, such as the use of sheds in the roof to capture the wind towards ventilation wells, allied to internal atria and rent of openings in opposite points with different pressure coefficients, dimensioned and properly shaded, cause an increase in the flow and number of air changes per hour inside the environments when compared to unilateral ventilation. In this way, each one is allowed to be occupied by a larger number of people, a requirement that is important for the functionality of the building, since the hospital is a teaching institution. In this way, the use of natural ventilation is potentiated and conditions are created to minimize the consumption of air conditioning, which contributes to the planning of a more energy efficient architecture.
