Architectural design should prioritize improving building energy efficiency. The potential of generative design can automatically generate building design alternatives, thereby saving time and increasing opportunities to discover design solutions that enhance building energy performance. In this context, the building envelope is considered one of the key factors affecting building energy consumption and is addressed during the early stages of design, making it directly relevant to architects. However, studies linking generative design with building design based on energy standards in the Thai context remain limited. Therefore, this study aims to develop a building envelope design support tool using a Generative Design process based on Thailand’s Building Energy Code (BEC), implemented as an add-in for software commonly used by architects in building design. The tool is designed to generate building design alternatives based on the Window-to-Wall Ratio (WWR), while automatically visualizing three-dimensional building models and calculating the Overall Thermal Transfer Value (OTTV). The results of this research provide architects and designers with a tool that can reduce design time, improve accuracy throughout the design process, and promote environmentally responsible building design in accordance with Thailand’s energy efficiency standards.
Asphalt pavements in Thailand frequently deteriorate due to moisture damage and rutting under tropical climate and heavy traffic, leading to high maintenance costs. Conventional rehabilitation by milling and replacing damaged layers generates large amounts of Reclaimed Asphalt Pavement (RAP). Although RAP is reused to enhance sustainability, its aged binder suffers from oxidative hardening and reduced performance, requiring rejuvenation. Most conventional rejuvenators are petroleum-based and contribute to environmental pollution. Therefore, this study proposes environmentally friendly alternatives using bio-oil and biochar derived from sugarcane bagasse, along with Fatty Acid Methyl Ester (FAME), to restore RAP performance while promoting sustainable waste utilization. The objective of this research is to evaluate the effects of different proportions of these natural rejuvenating agents on recycled asphalt mixtures containing 80% RAP and 20% virgin aggregates. The mixtures were tested using the Marshall Stability and Tensile Strength Ratio (TSR) tests under dry and wet conditions to assess strength and moisture susceptibility. The results aim to determine whether these natural materials can effectively restore RAP properties to meet standard performance requirements.
