TK Pahoa Kindergarten, with around 900 students from middle-to-high income families, stands out as a modern green educational institution that has achieved Greenship Netzero Ready certification. The design of the kindergarten emphasizes sustainability and comfort. Every classroom, hallway, and communal area is equipped with natural ventilation. Additionally, the classrooms feature a simple mechanical ventilation system and stack effect to ensure adaptive thermal comfort under any condition. The green roofs provide natural cooling and insulation, contributing to the building's overall energy efficiency. Impressively, the kindergarten maintains a very low Energy Use Intensity (EUI), averaging 19.31 kWh/m², with 20% of its energy needs met by rooftop solar panels. The building's rectangular masses are slender, with the longest sides facing south and north. This orientation effectively avoids direct sunlight radiation on the west and east sides while allowing wind to penetrate the long spaces in between, which serve as wind tunnels. This design provides sufficient air velocity, enabling a cross-ventilation effect throughout the indoor spaces of the classrooms.
