Universidad de Zaragoza (orcid)0000-0002-9929-2765 Water supply and energy in residential buildings: Potential savings and financial profitability 2019 Access copy available to the general public Unrestricted This article examines the suitability of water supply installations in residential buildings for the pressure conditions of the main water network, and evaluates the energy saving possibilities associated with pumping water into homes. It assesses the situation and the options for renovation in a sample of 151 buildings in the city of Zaragoza (Spain), estimating the savings in electric power and the possible financial returns that could be obtained. The results show that in half the buildings, the installations are inadequate and lead to inefficient energy use, which could be avoided by renovation. However, they also show that in many cases, this type of retrofitting would not be profitable for the building owners, meaning that technically viable solutions may not necessarily be financially viable. To mitigate or avoid the energy inefficiency in question, the public sector could step in by informing and financing support for building owners and regulating in the areas of town planning and construction. info:eu-repo/grantAgreement/ES/DGA/S23-17R info:eu-repo/grantAgreement/ES/MINIET/RENOVEA info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.576 2019 ENVIRONMENTAL SCIENCES 120 / 265 = 0.453 2019 Q2 T2 ENVIRONMENTAL STUDIES 53 / 123 = 0.431 2019 Q2 T2 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 26 / 41 = 0.634 2019 Q3 T2 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 6 / 8 = 0.75 2019 Q3 T3 0.581 2019 Energy Engineering and Power Technology 2019 Q2 Environmental Science (miscellaneous) 2019 Q2 Renewable Energy, Sustainability and the Environment 2019 Q2 Management, Monitoring, Policy and Law 2019 Q2 Geography, Planning and Development 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Colás, D.
