Classification of typical layout design for Indonesian apartment buildings

Along with rapid urbanization, housing development increased in major cities worldwide. Public and private apartments have been constructed rapidly in Indonesia to accelerate housing provision, particularly in urbanized areas of major cities. From the early era of apartment construction to the present, many design prototypes have been implemented for various specific purposes such as energy-saving. Nevertheless, no comprehensive study has determined a typical layout of apartment buildings in Indonesia. The typical layout design is useful as the base model for building simulations. This study sought to classify the typical layout design of public and private apartments in Indonesia, using the selected building drawing data ranging from 1986 to 2021. We obtained primary data consisting of 268 public apartments from 22 cities and 268 private apartments from 9 major cities in Indonesia. To determine the typical layouts, both qualitative and quantitative analyses were conducted. As a result of this study, a pair of typical public and private apartment buildings which include the 1-bedroom unit and 2-bedroom unit types have been selected as the typical layout of the Indonesian apartment building. The results of the typical layout classification could be utilized as a standard testing model for designing future apartment building prototypes

Embodied energy and carbon assessment of existing affordable apartments in Indonesia

The Indonesian government is making a tremendous effort in the provision of affordable public apartments (Rusunawa) across the country. Rusunawa buildings were designed and built considering urban planning, environmental impact, architecture, strength, safety, health, comfort, and accessibility requirements. However, in terms of climate change mitigation, there is little analysis of the building type’s embodied energy and carbon emissions. In this study, we investigated the Rusunawa buildings built by the central government, local government, and state-owned housing company considering the typical layout of the existing Rusunawa to identify the building’s embodied energy and carbon emissions using the cradle to end of use boundary. Rusunawa documents were collected and selected based on the required bill of quantity and drawings to quantify the building materials. The impacts of typical building materials on the embodied energy and carbon emissions of the roof, exterior wall, and partition wall were identified. The results showed that the building’s structural systems influenced the resultant embodied energy and carbon footprints the most, followed by walls, roof, painting, ceiling, doors and windows, and flooring. Among these structural systems, the precast concrete had a lower impact than the conventional reinforced concrete on these footprints. Overall, the Rusunawa buildings had an average embodied energy of 3950 to 8766 MJ/m2 and an average embodied carbon emissions of 328 to 871 kgCO2/m2. In particular, Rusunawa clusters, 1BR2 and 2BR1 had the smallest embodied energy and carbon emissions for the one- and two-bedroom apartment types. A high-rise Rusunawa had the smallest embodied energy and carbon emissions per floor area compared to those of low- and mid-rise. Several embodied energy and carbon values were proposed to be the baselines for the future lower-carbon Rusunawa design. These results could be adopted and developed for the central government’s regulations and guidelines to determine the current energy intensity and carbon emission of the existing Rusunawa and also to verify the future Rusunawa design

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
