Cristian Petcu is a scientific researcher (CSI) who has been working since 2002 at the National Institute for Research & Development URBAN-INCERC. From 2010 to 2018, he served as the head of the Laboratory of Research and Testing for Thermal Protection and Energy Saving in Construction at NIRD URBAN-INCERC. His doctoral thesis, completed in 2010, focused on the multiparametric energy analysis of building HVAC systems and building envelopes. As part of his research, he developed and validated a dynamic mathematical model for building simulations based on principles of building physics. This algorithm was implemented into software and applied to assess microclimate management systems, including free-running temperatures and energy demands for heating and cooling. He has extensive experience in building services, IT (VBA, MySQL, and PHP), and building materials. He is also a certified energy auditor for buildings. On behalf of NIRD URBAN-INCERC, he has successfully secured R&D funds by competing in national programs and has co-ordinated several projects. In addition to his research work, Cristian Petcu is actively involved in standardization efforts. He is a member of CT 281 (Thermal Performance of Buildings and Building Elements) and CT 302 (Heating, Ventilation, and Air Conditioning Installations). These roles demonstrate his commitment to advancing industry standards and best practices in his field of expertise.
