Automated device, method, and recording medium for building life cycle assessment

Automated Life Cycle Assessment Device for Selecting Key Building Materials Based on Environmental Impact Factors

This technology is an automated life cycle assessment device that receives building material codes, stores environmental impact factors by material and energy source, calculates environmental scores for each material, and selects key building materials based on their contribution ratio.

Evaluating the life cycle environmental impact of a building requires calculating the impact of numerous materials, which has historically made it difficult to efficiently automate the selection of key materials for assessment.

By calculating environmental scores for each material and automatically selecting those with the highest contribution, this technology can be integrated into building life cycle assessment systems to automate and streamline the evaluation process.

Key Features:

• An input unit that receives codes for multiple building materials, including their types and quantities.
• A database unit that stores primary environmental impact factors per unit of material input and secondary environmental impact factors per unit of energy consumption for each code.
• A calculation unit that computes the input volume for each material using its code and derives multiple environmental scores.
• A material selection unit that identifies key building materials by ranking them according to their contribution ratio to the total environmental score.
