Building Life Cycle Sustainability Assessment Device for Deriving Environmental, Cost, and Social Impact Indices
This technology is a sustainability assessment device that derives environmental, cost, and social impact indices by storing coefficients for building materials and energy sources, calculating life cycle assessment values, and dividing them by reference values.
Building sustainability requires consideration of not only environmental factors but also cost and social impacts; however, there has been a challenge in integrating these into a single index for quantitative assessment.
By calculating and integrating assessment values across these three areas as indices relative to reference values, this technology can be applied to building sustainability assessments to quantitatively evaluate environmental, cost, and social impacts simultaneously.
Key Features:
- A first storage unit that stores reference environmental impact assessment values along with sets of environmental impact coefficients for materials and energy sources, and an input unit that receives input for input and consumption quantities.
- A first calculation unit and output unit that derive the environmental impact index by summing the environmental impact assessment values of materials and energy sources to obtain a life cycle value and dividing it by the reference value.
- A second calculation unit and output unit that derive the cost index by summing the cost assessment values of materials and energy sources to obtain a life cycle cost assessment value and dividing it by the reference value.
- A third calculation unit and output unit that derive the social impact index by calculating the life cycle social impact assessment value using social impact coefficients and dividing it by the reference value.
