The Brazilian Building Performance Standard NBR 15575-4:2021 establishes criteria for the thermal performance of external vertical envelope systems (SVVE). In Bioclimatic Zone 3 (e.g., São Paulo and Curitiba plateau areas), which envelope property combination most effectively satisfies the summer and winter minimum thermal criteria without excessive reliance on active HVAC systems?

Lightweight single-skin curtain walls with high solar heat gain coefficients (SHGC > 0.80) to maximize solar heating throughout the entire winter and summer seasons. High thermal transmittance (U > 4.5 W/(m²·K)) walls coupled with dark exterior absorptance (α > 0.85) to store nighttime radiant temperatures in peripheral partitions. Adequate thermal transmittance (U ≤ 2.5 W/(m²·K)) and envelope thermal capacity, combined with operable solar shading and summer cross-ventilation. Completely airtight non-operable fenestration with single-pane clear float glazing to maintain static internal humidity and prevent interior air convection currents.

Correct Answer:

Adequate thermal transmittance (U ≤ 2.5 W/(m²·K)) and envelope thermal capacity, combined with operable solar shading and summer cross-ventilation.
