A Case Study in Building Energy Passportization

The operating energy costs of buildings account for approximately 70-80% of the total costs throughout the entire life cycle of a building. From the moment putting the building into operation, it begins to consume energy, mechanical, electrical, and natural resources. In buildings, all construction and technical systems naturally degrade over time, both in terms of performance and efficiency, i.e. operating and maintenance building costs are rising, energy consumption is increasing, and microclimate quality is declining. As a solution to this issue, it is possible to consider building energy passport (BEP), as a tool to control the optimal building operation according to the indicators of the building passport and as an encouragement way of cities' sustainability.  The building passport by its energy efficiency (BEP) and rational use of material resources is a special document-a certificate that contains information about the geometric and technical parameters of the building, its functional purpose, design solutions, thermal characteristics, and energy performance. This paper discusses the current state of the building passportization process in Azerbaijan, and analyzes the existing shortcomings. Categories and component parts of BEP, types and levels of building information and data, scheme of inputs and extractions data during the building life cycle, key tasks of BEP, and strategic actions for the successful development of BEP are given. Building energy efficiency rating classes are calculated, and the main procedures to enhance the energy efficiency class are given. The requirements for experts who carry out the buildings' passportization are systematized.   Received: 1 August 2023 | Revised: 13 September 2023 | Accepted: 20 September 2023   Conflicts of Interest The author declares that she has no conflicts of interest to this work.   Data Availability Statement Data available on request from the corresponding author upon reasonable request.   Author Contribution Statement Samira Akbarova: Conceptualization, Methodology, Software, Validation, Formal analysis, Investigation, Resources, Data curation, Writing - original draft, Project administration.
