Analysis of the exergy-consumption of four types of buildings

    Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review


    This paper proposes a comparison between the use of exergy analysis and traditional energy analysis for buildings. The principles of exergy analysis are outlined, and a specific method for buildings is proposed. The results of this analysis show that a long-term increase in the sustainability of buildings can be achieved only by sharply reducing the energy demand of electrical appliances and by improving the efficiency of the electricity production process. Improvements in the exergetic efficiency of heating and cooling systems that can be obtained by applying low-temperature heating and high-temperature cooling can also have positive effects on sustainability, but further reductions in the demand for heating and cooling by passive building physics measures will have no long-term effects.
