1. Why are green building criteria necessary?
Green building cannot rely on subjective claims or generic statements. Clear criteria provide an objective framework to assess sustainability performance in a measurable and comparable way.

2. Energy efficiency as a core criterion
Green buildings are designed and operated to minimize energy demand through appropriate architectural design, efficient systems, and responsible usage, reducing emissions and long-term operational costs.

3. Water and resource efficiency
Efficient water use, water-saving fixtures, and reduced resource waste are essential criteria for green buildings, helping to preserve natural resources and reduce environmental pressure.

4. Materials and construction resources
Green buildings prioritize materials that are appropriate for their function, durable, and capable of reducing repairs over the building lifecycle. Correct material selection and application minimize waste and resource consumption.

5. Indoor environmental quality and occupant health
Indoor air quality, natural lighting, moisture control, and material safety directly affect occupant health and comfort. Green buildings aim to provide healthy, safe, and comfortable living and working environments.

6. Operational efficiency and lifecycle performance
A building is not truly green at completion alone. Lifecycle performance evaluates how well a building can be operated, maintained, renovated, and optimized over time with minimal environmental and economic cost.

7. Interconnection between green building criteria
Green building criteria are interdependent. A poor decision in one area can undermine overall sustainability performance across the building lifecycle.

8. BUMATECH’s perspective
BUMATECH approaches green building criteria as an integrated system, where materials, construction techniques, and application guidance work together to meet sustainability goals in a practical and effective manner.

9. Conclusion
Core green building criteria provide a solid foundation for implementing sustainable construction. When applied holistically, these criteria enable long-term value creation for buildings and society.
