BIM-based modeling system for building life cycle assessment

BIM Modeling System for Building Life Cycle Assessment Incorporating Key Greenhouse Gas Materials

This technology is a system that supports the evaluation of a building's environmental performance using BIM authoring software. It identifies construction materials that exceed a specific greenhouse gas emission threshold as "key materials," sets them in a BIM library, and generates family data mapped to standard item codes and environmental impact data.

Existing building environmental performance assessments have been limited by the difficulty of efficiently conducting life cycle assessments, as it is challenging to manually incorporate vast amounts of material information.

By selecting key materials and building them as families within a BIM library, this technology can be applied to building life cycle assessments, enabling efficient environmental performance evaluation.

Key Features:

• Key material selection module that identifies construction materials with total greenhouse gas emissions exceeding a certain threshold as key materials.
• Key material management module that registers and manages selected key materials as individual items within a BIM library.
• Key material family generation module that creates family data by mapping key materials to Public Procurement Service standard item codes and environmental impact data.
• Key material family generation module that configures generated family data into a BIM library for use in environmental performance assessments.
