Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive literature coverage (2015-2025).
- +Adherence to PRISMA 2020 guidelines for systematic review.
Limitations
The complexity of real-world implementation and the difficulty in quantifying social and environmental impacts can be significant limitations for student projects.
Reliability & validity
The reliability of the review is enhanced by the systematic methodology (PRISMA 2020) and the use of multiple reputable databases. Validity is supported by the comprehensive scope of the analysis covering key aspects of HRES optimization.
Think critically
How can designers effectively balance potentially conflicting economic, environmental, and social objectives in the design of complex systems, and what methodologies are best suited for this?
Design Principles
"Holistic system design requires the integration of diverse objectives, including economic, environmental, social, and resilience factors, to achieve truly sustainable solutions."
This evolution reflects a growing demand for sustainable and socially responsible design. Designers and engineers must now integrate a broader set of objectives, including environmental footprint and societal benefits, into their optimization strategies for complex systems.
What This Means for Your Design
When designing systems that use multiple types of renewable energy, it's not just about making them cheap and efficient anymore. Designers now have to think about how these systems affect the environment and society too.
