Abstract
The impact of properly managing energy in hospitals is significant, due to the high bills and polluting emissions, and is complex, due to the wide range of energy consuming equipment to be kept always running. Energy efficiency plans in hospitals, which are pivotal in the European wide effort to redevelop existing buildings, have to be carried out as a part of a wider redesign process and must encompass complex data analysis and modeling. Based on the activity carried out within the European funded project H2020/MSCA/STEER, this work elaborates on the methodology, as tested on a building information model of a health center in Sicily, to identify positive and negative aspects of energy-related technology options to keep hospitals efficient. The main steps of the methodology carried out in the health center were: (1) collect data and input it in a digital model; (2) create and test a simplified quasi-steady state model of the building; (3) create a dynamic simulation model of the building; (4) run dynamic and simplified model simulations of the energy performance of the building; (5) compare results obtained from the two models in various scenarios, showing that the relevant differences after indicative interventions and parameter changes are equivalent.

Notes
- 1.
The project, that started on December 2014 and ended on November 2018, was run by a consortium formed by: Zephyro SpA (Italy), Politecnico di Milano (Italy), Afeka College University (Israel), Industrial System Institute (Greece), CTAdventure (Poland), Universitaet Bayreuth (Germany), Enertech Solutions (Italy), Meazon (Greece), Afeka Yssumim (Israel).

This point was made by, Giovanna Acampa, in addressing an international conference on “Evaluation of quality in architectural design” held in Rome on October 22nd–23th _ To be published.

In 2006, The European Parliament set the goal to reach zero soil consumption by 2050—Communication from the Commission to the Council, the European Parliament, the European Economic and Social Committee and the Committee of the Regions—Thematic Strategy for Soil Protection.

Such Measurement & Verification Plans are increasingly prepared according to the so-called IPMVP protocol.

More precisely, the model code was developed using the Matlab-code compatible GNU Octave (https://www.gnu.org/software/octave/).
- 7.
It should be mentioned that the modelling work was based on data derived from the building audit and that there is some missing information in it, for instance related to rooms with IT servers and paper archives. This is one of the reasons that led the consortium to also develop a detailed dynamic model, in order to exploit comparisons based on the credibility of the EnergyPlus tool, even if certain modeling decisions may slightly depart from actual conditions.
