The optimization model, formulated as mixed integer linear programming problem, incorporates dynamic operating conditions through time-dependent local climatic data, energy resources, energy demands, electricity prices, and electricity CO2 emission factors. The methodology is applied to a case study of a residential building in Spain. First, the single-objective solutions are obtained, highlighting their fundamental differences regarding the installation of cogeneration (included in the optimal total annual cost solution) and solar-based technologies (included in the optimal total annual CO2 emissions solution). Then, the Pareto curve is generated, and a decision-making approach is proposed to select the preferred trade-off solutions based on the marginal cost of CO2 emissions saved. Additionally, sensitivity analyses are performed to investigate the influence of key parameters concerning energy resources prices, investment costs, and rooftop area. The analyses of the trade-off solutions verify the enormous potential for CO2 emissions reduction, which can reach 32.3% with only 1.1% higher costs by displacing cogeneration in favor of the heat pump and the electric grid. Besides, with a modest cost increase of 7.3%, photovoltaic panels are incorporated, promoting an even greater CO2 emissions reduction of 45.2%. info:eu-repo/grantAgreement/ES/DGA/T55-17R info:eu-repo/grantAgreement/ES/MINECO/ENE2017-87711-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.741 2019 NUCLEAR SCIENCE & TECHNOLOGY 1 / 34 = 0.029 2019 Q1 T1 ENERGY & FUELS 46 / 112 = 0.411 2019 Q2 T2 0.785 2019 Nuclear Energy and Engineering 2019 Q1 Renewable Energy, Sustainability and the Environment 2019 Q2 Energy Engineering and Power Technology 2019 Q2 Fuel Technology 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4411-9834 Lozano, Miguel Ángel Universidad de Zaragoza (orcid)0000-0002-5161-7209 Serra, Luis María Universidad de Zaragoza 5004 590 Universidad de Zaragoza Dpto.
