Summary
This study analyzes waste indicators in 10 global green building rating systems (GBRS). Proper waste management significantly boosts a building's overall sustainability score.
Area of Science:
- Environmental Science
- Sustainable Architecture
- Waste Management
Background:
- Green Building Rating Systems (GBRS) assess building sustainability using diverse indicators.
- Waste management is a key category within GBRS, but indicator scope and focus vary significantly.
- Existing GBRS lack a standardized approach to waste assessment.
Purpose of the Study:
- To identify and classify waste-related indicators across 10 major global GBRS.
- To analyze the weighting and criteria used for waste assessment in different GBRS.
- To evaluate the impact of waste management on building sustainability through a case study.
Main Methods:
- Comparative analysis of waste indicators from 10 selected GBRS.
- Classification of indicators based on waste type, building lifecycle, waste hierarchy, and management stages.
- Implementation of GBRS waste indicators in a Colombian building case study.
Main Results:
- Significant variation exists in the number, scope, and weighting of waste indicators among GBRS.
- The study quantified the current waste-related sustainability performance of a case study building.
- Identified specific improvement actions to enhance a building's waste management score.
Conclusions:
- Standardizing waste indicators in GBRS is crucial for consistent sustainability assessment.
- Effective waste management practices demonstrably improve a building's overall sustainability rating.
- GBRS can be powerful tools for promoting better waste management in the built environment.
