Um estudo comparativo entre Domus, EnergyPlus e o plug-in\u00a0<\/span>Shading n<\/span>o SketchUp foi realizado, simulando tr\u00eas cen\u00e1rios distintos:<\/span><\/p>

  1. Sem sombreamento ao redor da casa.<\/span><\/p><\/li>

  2. Sombreamento parcial ao redor da casa e dos pr\u00e9dios vizinhos.<\/span><\/p><\/li>

  3. Sombreamento completo, incluindo \u00e1rvores.<\/span><\/p><\/li><\/ol>

    As simula\u00e7\u00f5es foram conduzidas ao longo de um ano, com intervalos de 15 minutos, em Curitiba, Brasil.\u00a0<\/span><\/p>

    Tanto Domus quanto Shading conclu\u00edram com sucesso todas as simula\u00e7\u00f5es, enquanto o EnergyPlus enfrentou dificuldades com o terceiro cen\u00e1rio devido a limita\u00e7\u00f5es no modelo de \u00e1rvore.<\/span><\/p>

    Os resultados de custo computacional revelam que o tempo de execu\u00e7\u00e3o aumenta com a complexidade do modelo de sombreamento. Domus se destacou, completando a simula\u00e7\u00e3o mais complexa em menos de uma hora, enquanto o algoritmo PgC do EnergyPlus demandou quase 18 horas para o segundo caso, sem a presen\u00e7a de \u00e1rvores.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    A abordagem\u00a0<\/span>de design multicrit\u00e9rio para dispositivos de sombreamento complexos\u00a0<\/span>se baseia em duas etapas principais: um processo de busca para identificar solu\u00e7\u00f5es n\u00e3o dominadas e um m\u00e9todo de t\u00e9cnica de programa\u00e7\u00e3o f\u00edsica (physical programming),\u00a0 para classificar essas solu\u00e7\u00f5es de acordo com as prefer\u00eancias dos tomadores de decis\u00e3o.\u00a0<\/span><\/p>

    Uma novidade \u00e9 o c\u00e1lculo da fra\u00e7\u00e3o de superf\u00edcie interna ensolarada, feito por contagem de pixels, que se mostrou um algoritmo poderoso e de baixo custo computacional para simular qualquer forma geom\u00e9trica com precis\u00e3o.\u00a0<\/span><\/p>

    Os resultados demonstraram que o m\u00e9todo proposto \u00e9 eficaz na concep\u00e7\u00e3o de dispositivos de sombreamento complexos, reduzindo o consumo de energia e protegendo as superf\u00edcies internas contra o desbotamento.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
