On 18 December 2020 in Municipality of Dropulli AKBN and External Expert presented  the buildings targeted for refurbishment are to be subjected to energy audits performed by certified experts under the authority of the Consultant and his team of engineers, architects, structural designers, etc. In these audits, only the vital building data shall be gathered. In line with national and international standards, the audits will consist of measurements of the building envelope and surfaces (floors, wall areas, windows, roofs, etc.), estimation of the current U-values, retrieving the detailed and correct energy bills of the last three years (2018–2020), analyzing the building conditions (building physics, technical systems), and financial analyses taking into account the renovation of the building envelope, technical systems, as well as the building management.

The Consultant further specified EE Measures for the heating systems (for rooms and warm water production) to reach the energetic objectives. The Consultant considered applications of solar lighting energy in order to improve EE and to reduce power as well as fuel consumption as far as economically feasible.

The Consultant also specified concrete associated rehabilitation measures such as electrical and sanitary installations, water supply systems, leakages, mould, unsafe staircases, fire protection measures, etc. for financing under the project. The energy audits recorded and considered the civil works rehabilitation measures necessary in advance before starting to implement the proposed and approved EE-measures. This includes building physics, leakages, water infiltration, humidity in walls and roofs, avoidance of cold/heat bridges, gutters and hydraulic systems, etc.
