Bioclimatic Analysis in Pre‐Design Stage of Passive  House in Indonesia

Abstract

Abstract:The objective of this study is to investigate the climate characteristics of Indonesian regions using an Olgyay Bioclimatic chart, a Givoni-Milne Bioclimatic chart and a Mahoney Table as the pre-design stage in the development of a passive house design standard for residential house construction in Indonesia. Jakarta was the city chosen for deep analysis, because it represents most of the Indonesian regions in terms of temperature and relative humidity. The Olgyay Bioclimatic chart showed that the climate needs a high wind velocity to counteract the vapor pressure and shading in order to reduce solar gain entering the building. The Givoni-Milne Bioclimatic chart proposed natural ventilation and shading devices, while the Mahoney Table recommends open spaces for protection against hot wind, rooms single-banked and permanent provision for air movement. The composite size of the opening at body height is better to allow the wind to counter the high levels of humidity and temperature. Heavy walls and roofs are suggested, as well as the provision of protection devices for the high amount of rainfall. Energy simulation was also done to investigate the effectiveness of the passive strategy proposed by the bioclimatic analysis. These results give a contribution as the indispensable basis for the development of a passive house standard in Indonesia.

An overview of motivators and challenges of passive design strategies

“…There are no uniform PDS standards and guidelines regarding the implementation of PDS [34,36]. Also, the present studies indicate that there is a potential for adopting PDS in India [37]. Moreover, private sectors have just started to evaluate the value and cost of adopting PDS [38].…”

“…Furthermore, PDS is not mandated across all the states yet, although energy efficiency was prioritized over all other concerns, and it is expected to grow significantly [36]. In India, the support for the adoption of PDS from governmental bodies is still poor [37]. There are no uniform PDS standards and guidelines regarding the implementation of PDS [34,36].…”

The impact of climate change on the thermal-energy performance of the SCIP and ICF wall systems for social housing in Brazil

“…55 The results indicated an annual cooling energy demand 95% lower than the traditional building. Santy et al 56 investigated the Passive House in Jakarta, Indonesia, and the EnergyPlus results indicated only 30% of discomfort hours in a year when a light wall was combined with night ventilation. Sigalingging et al 57 investigated the potential benefits of the Passive House in Jakarta, Indonesia as well.…”

Bioclimatic Design Strategies Recommendations for Thermal Comfort Using Mahoney Tables in Hot Desert Bioclimatic Region.

“…Finally, with the right drainage scheme, windows can be covered by projections and roofs. Santy et al 2017, investigated the Indonesian climate characteristics using the Olgyay Bioclimatic Map, the Mahoney tables, and the Givoni -Milne Bioclimatic Map as the predesign step for the growth of a residential inactive home design benchmark. Jakarta was the city selected for research, in terms of relative humidity, and temperature.…”
