Challenges in low energy architecture : a case study from Egypt

Energy-efficient architecture is critical for enhancing indoor air quality and preserving occupant comfort, particularly in Egypt, where the challenges of energy consumption in the building sector are prominent.This study aims to identify barriers to the implementation of Low Energy Building (LEB) principles in Egypt and propose actionable strategies for overcoming these challenges. Using a mixed-methods approach that includes a comprehensive literature review, SPSS analysis, SWOT analysis, semi-structured interviews, and a questionnaire survey, we examined the factors limiting energy efficiency in the building sector. Our findings reveal nine significant barriers, with the most critical factors identified as design, technical solutions, expertise, and quality. The government building sector emerged as a prime candidate for intervention, highlighting the need for targeted policies to reduce energy consumption in this area. Furthermore, the study, compared the obtained results with leed,s cer-tified building (Credit Agricole bank New Cairo City, Egypt) to verify the obtained results.
