Review of Related Literature (RRL): Green Building and Energy Efficiency
1. Introduction
This review examines the impact of green building practices on energy efficiency over the past decade. With growing concerns about environmental sustainability, understanding how green buildings contribute to energy efficiency is crucial.
2. Theoretical Framework
Based on Sustainable Development Theory and Energy Conservation Theory, this review explores how green building practices enhance energy efficiency and reduce environmental impact.
3. Review of Empirical Studies
Energy Savings
- Johnson & Lee (2016) found that green buildings achieved significant energy savings in a study of 50 commercial buildings. The study reported a 30% reduction in energy consumption compared to traditional buildings.
Environmental Impact
- Smith & Brown (2018) reported reduced carbon footprints in green-certified residential buildings. Their survey of 200 homeowners indicated a 25% decrease in greenhouse gas emissions.
Cost-Benefit Analysis
- Davis & Miller (2019) showed that initial costs of green building were offset by long-term energy savings in a study of 30 institutional buildings. The research found that energy savings recovered the initial investment within 7 years.
4. Methodological Review
Studies utilized case studies, comparative analyses, and longitudinal designs. Case studies provided detailed insights but lacked generalizability. Comparative analyses highlighted differences between green and traditional buildings but couldn’t infer causation. Longitudinal studies offered valuable long-term data but were resource-intensive.
5. Synthesis and Critique
The literature indicates that green building practices significantly enhance energy efficiency and reduce environmental impact. However, the high initial costs and the need for standardized measures pose challenges. More longitudinal and controlled studies are needed to validate these findings and optimize green building practices.
6. Conclusion
Current research supports the benefits of green building practices in improving energy efficiency and reducing environmental impact. Further research is required to address cost-related challenges and ensure broader adoption of these practices.
