Analysis of Thermal and Aerodynamics Performance of Batak Toba Traditional House by Implementing Digital Simulation and Field Measurement

Abstract

Traditional house is believed to have a better thermal performance compared to the modern house. Utilization of passive design in buildings can refer to the passive system used in a traditional house through natural ventilation and local materials application. Digital simulation was used to evaluate the thermal performance of the Batak Toba Traditional House by comparing field measurement data; and as a validation tool. This study aims to determine the thermal performance and aerodynamic of Batak Toba Traditional House by using digital simulation and field measurements. The used method was by comparing the results of digital simulation analysis with indoor and outdoor direct temperature measurements of the Batak Toba Traditional House. The softwares used for simulation were Meteonorm, Ecotect and CFD-ACE+. The measurements were conducted for 24 hours in May 4 th-5 th and April 26 th-27 th 2013 within one hour time interval. The results of the analysis of digital simulation show the same phenomenon compared with the result of field measurement that is 80% in range thermal comfort within one year. Field measurement results showed that the thermal conditions resulted from all day field measurement was under the upper limit temperature reference of thermal comfort with natural ventilation, that is 29 °C.

“…Hingga saat ini, terdapat beberapa stategi yang telah diterapkan pada bangunan ataupun rumah ibadah untuk mendapatkan kenyamanan dalam bangunan. Pada penelitian yang dilakukan oleh Prasetyo (2016) di Sumatra, Mohammad (2016) di Jawa, Alahudin (2012) di Sulawesi, Bua'Toding dan Kindangen (2014) di Kalimantan, Karyono dkk. (2012) di Nusa Tenggara Barat menunjukkan bahwa atap memberikan pengaruh terhadap kenyamanan penghuni didalamnya.…”

The Impact of Tropical Vernacular Courtyard on Air Temperature Reduction The Case Study of Djaduk Ferianto's House

“…Several researchers have studied passive design strategies, which are summarized in design criteria, such as building orientation that stretches east-west (Beccali et al, 2018;Prasetyo, 2016;Sardjono, 2011), wind direction (Manzano-Agugliaro et al, 2015;Nguyen et al, 2011), slim building massing and the presence of a veranda (Nguyen et al, 2011;Nugroho, 2012), roof with a large slope, lightweight materials, roof openings, wide eaves (Beccali et al, 2018;Hildegardis et al, 2019;Nguyen et al, 2011;Victoria et al, 2017), thin walls made of lightweight materials (Hildegardis et al, 2019;Manzano-Agugliaro et al, 2015), porous walls (Nugroho, 2012;Prasetyo et al, 2017), proper placement and size of openings (Beccali et al, 2018;Victoria et al, 2017), platform floor with a certain height and floor gap (Prasetyo et al, 2017;Sardjono, 2011;Victoria et al, 2017), landscaping with shade plants and placement on the west side (Nugroho, 2018;Prasetyo, 2016). These criteria are increasingly complete with the latest research on passive design in contemporary buildings in the tropics.…”
