RESUMO: O presente trabalho apresenta uma componente dos resultados obtidos pelo Projeto NZEB_LAB, do Laboratório Nacional de Energia e Geologia, para o design de novos sistemas solares integrados a edifícios. O trabalho reporta o design e a simulação numérica via computação dinâmica de fluídos de um protótipo de sistema fotovoltaico térmico integrado a edifício (BIPVT – Building Integrated Photovoltaic Thermal system), desenvolvido e futuramente instalado na fachada do edifício Solar XXI, Lisboa, Portugal. O objetivo é detalhar o design do protótipo e caracterizar ocomportamento térmico do sistema em suas partes fluida e sólida dada uma condição de fronteira, através da análisedo perfil de temperatura, velocidade do ar e turbulência, levando em consideração a secção transversal do elemento em uma análise bidimensional. Foi possível visualizar um gradiante de temperatura no interior da caidade de ar na ordem de 17,5ºC.
ABSTRACT: This work presents a component of the results obtained by the NZEB_LAB Project, from the National Energy and Geology Laboratory, for the design of new solar systems integrated into buildings. The work reports the design and numerical simulation via dynamic fluid computation of a prototype of a building integrated photovoltaic thermal system (BIPVT - Building Integrated Photovoltaic Thermal system), developed and future installed on the facade of the Solar XXI building, Lisbon, Portugal. The objective is to detail the design of the prototype and characterize the thermal behavior of the system in its fluid and solid parts given a boundary condition, through the analysis of the temperature profile, air speed and turbulence, taking into account the cross section of the element in a two-dimensional analysis. It was possible to visualize a temperature gradient inside the air cavity in the order of 17.5ºC.
