(orcid)0000-0003-0231-8795 Design of affordable sustainable energy supply systems for residential buildings: A case study 2022 Access copy available to the general public Unrestricted The residential sector plays an important role to mitigate climate change due to its high energy consumption. Polygeneration systems are a suitable alternative enabling efficient use of natural resources with low environmental impact. However, their deployment depends, among other factors, on the economic cost and the legal restrictions. This work analyses the potential reduction of greenhouse gases emissions, expressed in CO2 -equivalent emissions (CO2eq), in residential buildings installing polygeneration systems and considering the current Spanish self-consumption regulation. This is achieved through a multiobjective optimization, applying a Mixed Integer Linear Programming model, considering economic, environmental and legal aspects. Obtained results provide interesting replicable lessons, and show the interest of collective installations, in which remarkable CO2eq emissions reductions, above 65% with respect to conventional systems, can be achieved at an affordable cost. Technologies such as photovoltaic, reversible heat pumps, biomass and thermal energy storage are competitive when properly integrated. Furthermore, the sale of renewable electricity to the grid under a net-billing scheme, with suitable electricity sale prices, is an appropriate approach, aligned with the European climate and energy policy. Nevertheless, the current Spanish self-consumption regulation is mostly appropriate for small-medium size residential buildings. info:eu-repo/grantAgreement/ES/DGA/T55-17R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.6 2022 NUCLEAR SCIENCE & TECHNOLOGY 1 / 34 = 0.029 2022 Q1 T1 ENERGY & FUELS 61 / 119 = 0.513 2022 Q3 T2 0.807 2022 Nuclear Energy and Engineering 2022 Q1 Renewable Energy, Sustainability and the Environment 2022 Q2 Energy Engineering and Power Technology 2022 Q2 Fuel Technology 2022 Q2 7.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Serra, Luis M.
