Abstract

The Indonesian National Standard (SNI) 6572:2001 on natural ventilation in buildings has not been updated in the last 20 years, while similar standards in other countries have been periodically improved. The development of science and technology, environmental conditions, coupled with the COVID-19 pandemic that affects the entire world are the basis for consideration of the adjustment of related standards. The purpose of this study is to look at the standards for natural ventilation in several countries, namely the United States, Singapore, Malaysia, and Australia, as well as identify criteria that can be applied according to conditions in Indonesia. The results showed that the need for natural ventilation in buildings in Indonesia by 5% has met the existing conditions. However, further studies regarding the need for natural ventilation that are adjusted based on the function of the room as determined by ASHRAE 62.1 need to be carried out.

Abstract

As population growth continues, so does consumption and the need for basic human necessities, necessitating ongoing development. This development process often relies on non-renewable resources, generates waste, and emits harmful gases, usually neglecting sustainability. The Circular Economy (CE) concept can be applied to support sustainability in the construction industry. This regenerative system replaces the linear economy, focusing on optimizing material utilization and value throughout the product lifecycle and reducing waste generation. Through a Systematic Literature Review based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, this research provides an overview of CE practice trends that the construction industry in Indonesia can adopt based on lessons learned from other countries. The results indicate that CE implementation in Indonesia is highly relevant and important for supporting sustainability from economic, environmental, and social perspectives. To achieve these benefits, Indonesia must overcome various barriers, including less supportive policies, low consumer demand, limitations in the supply chain, and technological and infrastructure constraints. The CE principles commonly applied by the Indonesian construction industry in waste are reduction, reuse, and recovery. To ensure the successful implementation of CE in the construction sector, the Indonesian construction industry can learn from the best CE practices implemented in other countries and adopt effective and efficient strategies to achieve sustainability. However, successful implementation requires commitment and collaboration from various stakeholders, including the government, industry, and academia.
