Void Vertikal, Penghawaan, Pendinginan, Kualitas UdaraAbstrak
Void vertikal dapat meningkatkan kinerja penghawaan alami untuk pendinginan fisiologis dan kualitas udara dalam ruangan (IAQ), khususnya pada rumah kos sebagai bentuk hunian bersama. Pengaruh void terhadap penghawaan ditentukan oleh berbagai variabel desain seperti proporsi bukaan, rasio void terhadap bangunan, aspek rasio void, dan posisi void. Melalui modifikasi variabel-variabel desain tersebut, efek void vertikal terhadap penghawaan dapat ditingkatkan. Untuk menyelidiki pengaruh variabel desain terhadap kinerja penghawaan, penelitian dilakukan melalui survei lapangan dan pengukuran kondisi iklim mikro. Metode statistik deskriptif digunakan untuk menganalisis pengaruh desain yang berbeda pada dua rumah kos terhadap kinerja penghawaan. Hasil penelitian ini dapat digunakan sebagai pertimbangan desain hunian bertingkat rendah untuk meningkatkan kinerja penghawaan alami. Temuan menunjukkan bahwa kualitas udara yang ditentukan oleh konsentrasi CO2 tetap berada di sekitar 400–600 ppm. Hal ini disebabkan oleh tingkat habitasi yang rendah dan volume void yang besar, terlepas dari desain void atau kecepatan udara. Kecepatan aliran udara sebagai indikator pendinginan fisiologis bervariasi antara siang dan malam. Penghawaan pada siang hari lebih efektif untuk lantai atas karena daya apung termal dan kecepatan angin yang lebih tinggi. Penghawaan malam hari kurang memadai dengan aliran udara yang lebih lemah, terutama untuk pendinginan fisiologis di lantai atas. Penyesuaian rasio void dapat meningkatkan kinerja penghawaan alami. Void yang sempit meningkatkan aliran udara ke atas pada malam hari, sedangkan rasio aspek void yang lebih besar meningkatkan aliran udara pada siang hari.
