The purpose of this qualitative study is to explore barriers to cultural and linguistic diversity teaching in mainstream secondary schools in South Africa.

The study was underpinned by the culturally responsive pedagogy theory as a framework. Face-to-face interviews were conducted to explore the barriers to teaching in culturally and linguistically diverse (CLD) classrooms.

The authors found that teachers experience a plethora of challenges in teaching CLD learners. The findings show that culturally responsive practices, collaboration with relevant stakeholders and seeking professional development opportunities may advance the productive engagement of CLD learners in secondary schools.

Pre-service and in-service teachers should be conscientious about CLD teaching and learning through professional development. Teachers should be trained and retrained to accommodate CLD learners.

This study highlights significant aspects that hinder the inclusion of CLD learners and encourages the Department of Higher Education (tertiary institutions) and the Department of Basic Education Curriculum Developers to reconsider aspects of CLD in curriculum planning.

The purpose of this study is to investigate and analyse the potential of existing buildings in the UK to contribute to the net-zero emissions target. Specifically, it aims to address the significant emissions from building fabrics which pose a threat to achieving these targets if not properly addressed.

The study, based on a literature review and ten (10) case studies, explored five investigative approaches for evaluating building fabric: thermal imaging, in situ U-value testing, airtightness testing, energy assessment and condensation risk analysis. Cross-case analysis was used to evaluate both case studies using each approach. These methodologies were pivotal in assessing buildings’ existing condition and energy consumption and contributing to the UK’s net-zero ambitions.

Findings reveal that incorporating the earlier approaches into the building fabric showed great benefits. Significant temperature regulation issues were identified, energy consumption decreased by 15% after improvements, poor insulation and artistry quality affected the U-values of buildings. Implementing retrofits such as solar panels, air vents, insulation, heat recovery and air-sourced heat pumps significantly improved thermal performance while reducing energy consumption. Pulse technology proved effective in measuring airtightness, even in extremely airtight houses, and high airflow and moisture management were essential in preserving historic building fabric.

The research stresses the need to understand investigative approaches’ strengths, limitations and synergies for cost-effective energy performance strategies. It emphasizes the urgency of eliminating carbon dioxide (CO₂) and greenhouse gas emissions to combat global warming and meet the 1.5° C threshold.
