Analysis of the Energy Optimization Method of Apartment Buildings by Using Generative Design in Terms of Integrated Design

Year: 2025

Type: article

Abstract: Improving building energy efficiency has become essential for reducing global greenhouse gas emissions. (1) Background: We aim to strengthen early-stage collaboration among stakeholders based on integrated design principles, rather than relying solely on individual designers’ subjective decisions. The goal is to propose an objective method for optimizing apartment building layouts. (2) Methods: Accordingly, key design elements for energy optimization were identified, and corresponding energy usage prediction data were collected to build a database. Generative Design (GD) techniques were applied to generate and evaluate alternative layout configurations. (3) Results: The conventional apartment block layout process, which heavily depends on the expertise and intuition of experienced designers, was automated using Revit-Dynamo. An energy optimization method from the integrated design perspective was subsequently proposed. (4) Conclusions: GD enabled the identification of comprehensively optimized layout alternatives. We demonstrate the applicability of Revit-Dynamo-GBS in apartment complex design from an integrated design perspective and suggest improvements to existing certification systems and procedures in light of domestic policy considerations.
