Resumen:
State-of-the-art research suggests that energy systems are best
evaluated using exergy analysis, as exergy represents the real value of
an energy source, demonstrating it to be the only rational basis for
evaluation. After discovering the lack of thermodynamic integration into
stock modelling, this paper presents the development of an exergy-based
building stock model. The aim of this paper is twofold. Firstly, to
investigate the impact of large-scale future energy retrofit scenarios
in the English and Welsh (E&W) non-domestic sector, and secondly, to
determine the potential of exergy analysis in improving sectoral
efficiency and its potential implications on exergy-oriented policy
making. The research explores seven different large-scale future
retrofit scenarios that encompass typical, low-carbon, and low-exergy
approaches. Modelling results show that by 2050, current regulations
have the potential to reduce carbon emissions by up to 49.0 +/- 2.9%
and increasing sector thermodynamic efficiency from 10.7% to 13.7%. On
the other hand, a low-exergy oriented scenario based on renewable
electricity and heat pumps is able to reduce carbon emissions by 88.2
+/- 2.4%, achieving a sectoral exergy efficiency of 19.8%. This
modelling framework can provide energy policy makers with new insights
on policy options based on exergy indicators and the assessment of their
potential impact.
