Internal energy circulation solutions in heating, ventilation and air-conditioning systems: assessment method and comparative analysis
Abstrak
The paper presents an approach for assessing the sustainability of energy-saving measures in buildings based on the integral Sustainability Impact Index (SII), which incorporates the energy, environmental and circulatory characteristics of each solution. The methodology was tested on a case study of an office building, where energy-saving measures were structured into three groups and evaluated through a comparative analysis. The study also included the development of a circulatory solution based on the reuse of condenser heat from the building’s chiller units. The results demonstrate that the application of the SII clearly reflects the increasing importance of measures related to internal energy circulation. The SII value for the circulatory measure was found to be approximately twice as high as for the technical and operational groups, indicating its concentrated impact and potential to replace external energy resources. The proposed approach allows for a more accurate prioritization of sustainable solutions and can be applied in planning HVAC system modernization and developing building decarbonization strategies.
