Hospitals require the highest energy demands in non-residential buildings. They provide healthcare 24/7/365 and, at the same time, they ensure indoor air quality, thermal comfort and sterility. However, several studies reveal that high indoor temperatures and low relative humidity (RH) are often perceived in patient rooms during the heating season, suggesting an important energy saving potential. Against this background, radiant ceiling panel (RCP) systems result to be one of the most appropriate solutions as they allow to achieve significant energy savings while providing the highest level of thermal and acoustic comfort, as well as of infection control. In the present study the microclimatic survey of a patient room at Maggiore Hospital in Bologna, Italy, equipped with an air conditioning system integrated with RCP, has reported occupant thermal discomfort. Experimental data were used to calibrate a building model and dynamic building energy simulations were carried out to analyse indoor air temperature, relative humidity, predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD) indexes under different inlet air temperatures, to identify the best design conditions for energy efficiency and thermal comfort improvement. It was found that the highest advantages can be obtained when neutral air is supplied.

We investigate data-driven, simple-to-implement residential environmental models that can serve as the basis for energy saving algorithms in both retrofits and new designs of residential buildings. Despite the nonlinearity of the underlying dynamics, using Koopman operator theory framework in this study we show that a linear second order model embedding, that captures the physics that occur inside a single or multi zone space does well when compared with data simulated using EnergyPlus. This class of models has low complexity. We show that their parameters have physical significance for the large-scale dynamics of a building and are correlated to concepts such as the thermal mass. We investigate consequences of changing the thermal mass on the energy behavior of a building system and provide best practice design suggestions.

“…El EnPI desarrollado para la clínica no es complejo de calcular e implementar, por lo que puede ser manejado por el personal técnico, lo cual es esencial para el éxito del sistema de gestión. Comparado con otros estudios [6], [7], [9], [10], este es un enfoque más práctico y económico que no requiere la introducción de nuevas tecnologías.…”

“…Por otra parte, también se creó un método para establecer una línea de base comparación para edificaciones hospitalarias y definir los factores que afectan su consumo energético [5]; el estudio se desarrolló en 45 grandes hospitales (32% del total) en Tailandia; y como resultado se definió una línea base de comparación entre hospitales grandes que puede servir para el desarrollo de planes de eficiencia energética en hospitales. Otro estudio, enfocado en la reducción de la emisión de gases de efecto invernadero, evaluó el potencial de ahorro en dos edificaciones hospitalarias construidas entre 1970 y 1980 en la Europa del este [10]; se logró reducir el consumo energético y las emisiones de gases de efecto invernadero transformando los hospitales en edificaciones inteligentes. En Marruecos se dieron avances en una guía de buenas prácticas para mejorar la eficiencia energética en edificaciones hospitalarias para contribuir a los objetivos nacionales de eficiencia energética [11]; la metodología analiza diferentes EnPIs y su aplicación en contextos similares; y los resultados señalan que, en instalaciones hospitalarias, la introducción de estrategias de eficiencia energética está en sus inicios.…”

En este trabajo se desarrolla un sistema de gestión energética, basado norma ISO 50001, para la Clínica Portoazul, ubicada en la primera zona franca de salud de la Costa Atlántica. Durante el estudio se identificó la electricidad como el principal portador energético consumido en la clínica. Adicionalmente, se identificaron los equipos y/o sistemas con mayor demanda eléctrica. Basado en las diferentes mediciones y datos de consumo eléctrico de la clínica, se desarrolló una línea base y un indicador de desempeño garantizando una correlación R2 > 60%. El indicador de desempeño se utilizó como base para desarrollar el sistema de gestión energética. Los resultados de implementación del sistema de gestión entre enero y febrero de 2020 muestran una reducción del consumo de electricidad diario entre un 1 y un 15% respecto a la línea base.
