Case study of a smart campus in Spain 2023 Access copy available to the general public Unrestricted This work validates and demonstrates the potential of a methodology based on a continuous monitoring system with real time measurements, as a key support to make decisions on buildings energy systems based on quantitative data. For this work, a continuous loop-based monitoring methodology was designed and implemented to enhance the performance of Heating Ventilation and Air Conditioning (HVAC) systems by improving the energy efficiency of university buildings and the quality of life of the people who use them. The results from the case study, used to demonstrate the proposed methodology, can be extrapolated to the entire university in order to transform it into a smart campus. The case study also shows that the continuous measurement of temperatures allows to avoid excessive heating, reducing unnecessary energy consumption. Additionally, the case study shows the importance of monitoring CO2 concentration in rooms where occupancy is fluctuating, since it enables a control of the HVAC system based on the instantaneous CO2 level (and predictive in the immediate aftermath). This proposed measurement can save between 40% and 70% of HVAC energy consumption. The positive results obtained in this research show that implementing Internet of Things (IoT) smart ecosystems contribute to promote data-driven decisions in public tertiary buildings among decision-makers, politicians, and other stakeholders. info:eu-repo/grantAgreement/ES/MICINN/RYC2021-034265-I info:eu-repo/grantAgreement/ES/UZ/CAT019-2020-3 Zaragoza Vivienda UZ Chair info:eu-repo/grantAgreement/ES/UZ/EQUZ-2022-TEC-11 info:eu-repo/grantAgreement/ES/UZ/SGI-171481 info:eu-repo/grantAgreement/ES/UZ/2000-0074 SAMCA info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.6 2023 CONSTRUCTION & BUILDING TECHNOLOGY 10 / 92 = 0.109 2023 Q1 T1 ENGINEERING, CIVIL 11 / 182 = 0.06 2023 Q1 T1 ENERGY & FUELS 48 / 171 = 0.281 2023 Q2 T1 1.632 2023 Electrical and Electronic Engineering 2023 Q1 Mechanical Engineering 2023 Q1 Civil and Structural Engineering 2023 Q1 Building and Construction 2023 Q1 12.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Zalba, Belén Universidad de Zaragoza (orcid)0000-0002-6101-580X Casas, Roberto Universidad de Zaragoza (orcid)0000-0001-5316-8171 Cano, Enrique Universidad de Zaragoza (orcid)0000-0001-5137-2478 Guillén-Lambea, Silvia Universidad de Zaragoza (orcid)0000-0003-3269-023X López-Mesa, Belinda Universidad de Zaragoza (orcid)0000-0003-1458-7685 Martínez, Ignacio Universidad de Zaragoza (orcid)0000-0002-2887-2105 5015 110 Universidad de Zaragoza Dpto.
