Energy efficiency in sustainable buildings: implementation of green design and technology in Karawang Regency

Energy efficiency in sustainable buildings is a strategic approach to support environmentally friendly development and contribute to climate change mitigation. This study examines the implementation of green design and technology to enhance energy efficiency in buildings located in Karawang Regency, Indonesia. The research focuses on technologies such as energy-efficient lighting systems, thermal insulation materials, and optimized natural ventilation in building construction. A mixed-methods approach was employed, combining qualitative and quantitative analyses. Data were collected through field surveys, interviews with developers, and document reviews on the application of green technologies. The findings indicate that the integration of green design and technology can reduce energy consumption by up to 25% compared to conventional buildings. Additionally, public awareness and local government policy support play critical roles in the success of these initiatives. However, the study also identifies challenges, including the high initial cost of green technologies and limited public understanding of energy efficiency’s importance. Recommendations include strengthening stakeholder collaboration, providing incentives for adopting green technologies, and raising public awareness about the significance of sustainable development. This research provides valuable insights for policymakers, urban planners, and civil engineers in designing buildings that are both energy-efficient and sustainable. The findings contribute to the broader discourse on integrating green technology into sustainable infrastructure development globally.
