Results of the first SRI testing in the building sector in Bulgaria

The first SRI and SRI-ENACT Assessment Toolkit testing in Bulgaria was successfully carried out by the BSERC auditors in February-March 2024 on four different functional building types in four cities – Sofia, Plovdiv, Lovech and Sandanski. The locations are shown on the map.

The SRI testing procedure in the country is officially recognised and supported by the Ministry of Energy and the Sustainable Energy Development Agency.

The four buildings assessed according to their SRI level are as follows:

Office Buildng-2 Garitage Park in Sofia,… Total SRI Score 57.1%/Class D

Drama Theater  in the town of Lovech,.….… Total SRI Score 33.9%/Class F

Hospital „Saint George“ Block-1  in Plovdiv,…Total SRI Score 30.0%/Class F

Kindergarten “Dora Gabe” in Sandanski, … Total SRI Score 25.8%/Class F

The office building is new (built in 2019, BREEAM certified) and the other three buildings have been renovated.

After the upcoming training of 13 certified auditors to assess the SRI on a larger scale, the test will be extended to a total of 130 different buildings in Bulgaria.

The feedback from the SRI auditors on the use of the SRI-ENACT Assessment Toolkit was very positive. Their comments are summarised below:

  • The manual for registration and operation of the SRI-ENACT Assessment Tool has been prepared in the best possible way for the auditors/users.
  • The use of the SRI Assessment Toolkit software is easy and takes a short time if the required inputs of the analysed building are prepared in advance (e.g. from the building’s energy efficiency assessment report).
  • The tool’s menus are user-friendly and the dynamic pop-up auxiliary windows facilitate the processing of input data and the corresponding calculations of local SRI indicators for each of the building’s technical systems, as well as the building’s aggregated SRI.
  • The detailed catalogue of 54 intelligent control technologies introduced in the software is a significant contribution to speeding up the work of determining the levels of functional perfection of the building’s technical systems (domains).
