Decarbonizing HVAC Systems in Educational Buildings: Challenges and Solutions

The heating, ventilation, and air conditioning (HVAC) systems in educational buildings are significant contributors to energy consumption and greenhouse gas emissions. As the urgency to achieve carbon neutrality intensifies, decarbonizing HVAC systems has become a key priority in the retrofitting of educational infrastructure. This study aimed to investigate the challenges hindering the decarbonization of HVAC systems in educational buildings and to suggest viable solutions. A quantitative research approach was adopted, employing a structured questionnaire survey administered to professionals involved in HVAC operations across selected educational institutions in Gauteng province, South Africa. The findings reveal that the major challenges include high upfront costs of low-carbon HVAC technologies, limited technical expertise, and institutional inertia. However, respondents also highlighted opportunities such as government incentives, long-term energy savings, and growing support for climate action within the education sector. Solutions recommended include phased retrofitting strategies, capacity building for maintenance staff, and policy frameworks that support lifecycle costing and performance-based upgrades. Decarbonizing HVAC systems in educational buildings is both a necessity and an opportunity. A holistic and collaborative approach involving technical, financial, and policy interventions is essential. The study recommends targeted funding, awareness campaigns, and the integration of decarbonization goals into institutional infrastructure planning.
