KAJIAN KONSEP STACK EFFECT PADA BANGUNAN MULTIFUNGSI RUNGKUT ASRI UTARA DI SURABAYA

STUDY OF STACK EFFECT CONCEPT IN MULTIFUNCTION BUILDING AT RUNGKUT ASRI UTARA SURABAYA

Rahayu, Paulina Maria Setya 




ABSTRAK

Bangunan multifungsi merupakan salah satu model hunian di perkotaan untuk memenuhi kebutuhan fungsi tempat tinggal sekaligus fungsi lainnya sehubungan dengan lahan yang terbatasnilai tanah yang tinggi. Sistem penghawaan pada bangunan multifungsi Rungkut Asri Utara tidak dirancang menggunakan ventilasi silang.karena hanya mempunyai mempunyai bukaansatu sisi yaitu sisi depan saja. Penelitian kasus ini bertujuan untuk mengkaji elemen-elemen bukaan yang ada termasuk bukaan diatas ruang tangga melalui konsep penghawaan stack effect yaitu konsep ventilasi dengan aliran vertikal. Metode penelitian ini adalah penelitian lapangan melelui pendekatan studi kasus pada 4 empat kasus obyek sebagai sebagai sample dengan mengambil data fisik dan non fisik serta data-data yang berkaitan dengan elemen variable dari konsep penghawaan stack effect. Pengambilan data dilakukan dengan mengukur suhu kecepatan angina pengamatan arah angin serta pengukuran luas dan tinggi bukaan. Hasil penelitian pada kasusu obyek diatas menunjukkan bahwa obyek yang mempunyai bukaan di bagian depan dan semping dengan bukaan atas dalam posisi tertutup tidak terjadi ventilasi vertical. Pada obyek yang mempunyai bukaan depan dan bukaan samping pada lantai tiga hanya terjadi pergantian udaraair change kecepatan anginan rata-rata dalam bangunankurang dari 02 mdetik. Pada obyekyang mempunyai elemen bukaan satu sisi sisi depan dengan kondisi bukaan atas yang terbuka sebagai penangkap anginperan bukaan atas berpengaruh pada peluang gejala stack effect. Pada obyek yang bukan sisi depan menggunakan ventilasi mekanis kipas angin pergantian udara hanya dapat terjadi apabila bukaan atas diatas ruang tangga dalam posisi terbuka arah angin dominan adalah kebawah. Hasil penelitian pada kasus dengan posisi bukaan atas terbuka mengindikasikan terjadi ventilasi secara vertikal.ditandai dengan kecepatan udara dalam bangunan cukup signifikan yaitu antara 0.25 mdetik hingga 1.73 mdetik. Besaran dan arah kecepatan angina dalam bangunan sangat dipengaruhi oleh besaran kecepatan angin luar terhadap posisi bukaan.


ABSTRACT

Multifunction building is one of the settlement models in cities as a solution regarding the land area which getting more limited and the land value which getting higher everyday. The ventilation system of multifunction building in Rungkut Asri Utara is not design to use natural ventilation by cross ventilation concept because it only has single side opening that is only in the front side. The purpose of this research is to study the existing opening element through natural ventilation by stack effect concept ventilation concept by vertical air flow. The method of this research is field research through case approach. This research is stared by selecting 4 four case object as research samples as gathering data such as physical data non physical data and also data that are related with variable element of stack effect ventilation concept. The data was taken by measuring the temperature wind velocity wind direction and measuring the size and height of opening. The result of the observation shown that the building which had two side openings element front and leftright side with upper opening above the staircase was closed the vertical ventilation will not occurred. The object building which had single opening in front and side opening in third floor the air change occurred inside the building the wind velocity was less than 0.2 ms But the object building which only has single opening in front side and the upper opening was opened ten there is a chance where the stack effect phenomenon may occur. In the case where the object building uses electric fan in the front opening the air change will only happen when the upper opening above the staircase was opened and the wind direction will flow dominantly from above to below. In both cases when the upper opening is opened the result of research indicated that vertical ventilation occurred significantly with wind velocity values around 0.24 ms to 173 ms The velocity values and wind direction inside the building depend on the wind velocity values and wind direction outside the building.
