Teresa (orcid)0000-0001-7017-4178 Energy and environmental benefits of an integrated solar photovoltaic and thermal hybrid, seasonal storage and heat pump system for social housing 2022 Access copy available to the general public Unrestricted A facility based on a photovoltaic and thermal hybrid solar field with a seasonal storage tank coupled to a water-to-water heat pump is presented in this paper as an adequate energy supply system for a building of social homes in Zaragoza (Spain), currently under construction. Two types of complementary software have been used for the complete design, sizing, and simulation of the system. DesignBuilder was used to determine the hourly demands from the construction drawings, and TRNSYS was then implemented to dynamically simulate the whole energy system. System performance has been tested in terms of 3E aspects (energy, environmental and economic) with a few well-known key performance indicators. Results obtained by the combined use of the demand simulation software and quantification with different indicators (KPI) show that the proposed solution is suitable for this building: the calculated coverage of the domestic hot water demand is about 80%, the payback period is 8.5 years, and the installation could avoid 44, 200 kgCO2/year of global warming potential. To sum up, this paper shows how this novel, high-efficiency heating system is a good solution for social housing, owing to its low energy costs and a possible subsidization of a fraction of the high initial investment. © 2022 The Authors info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.4 2022 ENGINEERING, MECHANICAL 9 / 136 = 0.066 2022 Q1 T1 THERMODYNAMICS 7 / 63 = 0.111 2022 Q1 T1 MECHANICS 9 / 137 = 0.066 2022 Q1 T1 ENERGY & FUELS 40 / 119 = 0.336 2022 Q2 T2 1.559 2022 Energy Engineering and Power Technology 2022 Q1 Mechanical Engineering 2022 Q1 Industrial and Manufacturing Engineering 2022 Q1 Fluid Flow and Transfer Processes 2022 Q1 11.8 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez-Gracia, Amaya Universidad de Zaragoza (orcid)0000-0003-1238-8746 Uche, Javier Universidad de Zaragoza (orcid)0000-0003-4408-6881 Amo, Alejandro del Bayod-Rújula, Ángel A.
