The built environment plays a crucial role in global sustainability efforts. Buildings, infrastructure, and cities consume large amounts of energy and materials that shape social behavior, and lock in environmental impacts. Over the past two decades, research has produced a wide range of technical solutions to reduce these impacts. Renewable energy systems, energy-efficient buildings, alternative construction materials, and new construction methods are no longer experimental concepts. Many have proven technical and economic potential. Yet, real-world transformation remains slow and uneven. This gap suggests that sustainability challenges in the built environment are no longer driven by a lack of technology. Instead, …

CSID Journal of Infrastructure Development
Locust Bean Pod Ash (LBPA) is produced from the calcination of Locust Bean Pod (LBP), an agricultural waste of the African locust bean tree (Parkia biglobosa). This study evaluated the use of LBPA obtained through controlled calcination and open burning as a supplementary cementitious material (SCM) in high-strength concrete (HSC). Cement was replaced by LBPA at 5%, 10%, 15%, and 20% by weight using both ashes—LC for ash produced through calcination at 600 °C, and LO for ash obtained through open burning. Slump and strength were assessed, including compressive strength (100 × 100 × 100 mm cubes) and splitting tensile …

CSID Journal of Infrastructure Development
Shading devices are essential for reducing solar radiation and cooling loads in buildings located in tropical climates. In the Jakarta region, the highest solar factor is observed on west- and east-facing facades, followed by north- and south-facing orientations. National building policy in Indonesia encourages facades to face north–south to reduce solar heat gain. This study explores horizontal static and dynamic shading devices on north-facing facades and evaluates their impact on cooling load reduction and daylight performance. The methodology includes calculating and simulating energy use intensity (EUI) using EnergyPlus and conducting illuminance analysis using Radiance and Grasshopper. Key parameters considered in …

Smart buildings have become a key part of the Fourth Industrial Revolution, driven by the need for efficient, sustainable, and adaptive built environments. Their importance is growing alongside Indonesia’s effort to develop smart cities. This study compares Indonesia’s national smart building certification system, established under Ministerial Regulation No. 10 of 2023, with two international systems: the European Union’s Smart Readiness Indicator (SRI) and the SmartScore certification. The analysis uses a literature review and comparative method to examine each system’s assessment criteria, scoring method, and certification tier. The findings show that Indonesia’s regulation includes six parameters, such as cybersecurity and operational …
