Advancing Experiential Learning in Architectural Engineering through the Purdue zEDGE Test House: A Case Study in Hands-On Building Science Education

This paper presents a case study on the zEDGE Test House, a mobile, sensor-integrated living laboratory at Purdue University developed to advance architectural engineering education through experiential learning. The initiative responds to the need for engineering curricula to bridge the gap between theoretical instruction and practical application, particularly in areas such as building science, HVAC&R systems, and energy efficiency. The zEDGE Test House enables students to investigate real-world building systems through hands-on experimentation and data-driven analysis. Three experiential learning modules were developed and implemented within architectural engineering courses: (1) energy efficiency and sustainable systems, (2) ventilation analysis via the tracer gas method, and (3) thermal conductivity and heat transfer in building materials. To evaluate effectiveness, graded deliverables, informal discussions, and end-of-semester evaluations were used; 65%–96% of students across five semesters agreed that the laboratories enhanced their ability to meet course objectives. These findings indicate that the module/s strengthened conceptual understanding, enhanced problem-solving skills, and increased confidence in applying engineering principles to practice. The zEDGE model offers a scalable and replicable framework for institutions seeking to integrate living laboratories into architectural engineering education. By combining sensor-enabled environments, evidence-based instructional practices, and real-world experimentation, the model enhances student preparedness for careers in sustainable building design and HVAC&R system optimization. This study highlights the broader potential of experiential learning platforms to transform architectural engineering education, aligning academic instruction with professional practice and emerging industry needs.
