Ferramentas de Avaliação de Edifícios Sustentáveis (GBRTs), como LEED, BREEAM, GRIHA e WELL, avaliam a sustentabilidade, mas frequentemente não incluem um marco padronizado para estratégias de design passivo, essenciais em climas quentes e úmidos. Este estudo propõe um modelo holístico para otimizar essas estratégias, integrando análises qualitativas de especialistas e dados quantitativos entre os sistemas. Utilizando PCA, MCDA e regressão, é criado um sistema de pontuação ponderada para comparação estratégica. A análise mostra que estratégias passivas combinadas aumentam significativamente o desempenho sustentável. Home Performance Index (24,72) e ARZ (23,06) obtêm as maiores pontuações, enquanto LEED (10,91) e GRIHA (9,96) indicam necessidade de aprimoramento. O modelo AHP proposto foca em otimização da envoltória, ventilação natural, isolamento e seleção de materiais. Estudos de caso demonstram que estratégias como sombreamento e ventilação reduzem a carga térmica em 59%, diminuem a temperatura interna em 2,5–3 °C e economizam até 29% de energia, comprovando sua eficácia climática.
