The energy measures implemented in the HURH will provide savings of 35%

Since the HURH began operating in 2009, various measures of energy efficiency have been implemented, which have reduced natural gas and electricity consumption by 30%. The actions foreseen in the energy axis of the LIFE Smart Hospital Project continue with this objective of optimization and saving in the consumption.

The Hospital has four boilers, equipped with modulating burners depending on the thermal demand. From January 2016, the Project has implemented a digital combustion control, which allows the air introduced by the burner in the boiler to be adjusted to the level required at each moment by the burner operating point, which is allowing an electric and thermal saving.

On the other hand, at the beginning of the year the lighting control of the luminaires in the dressing rooms and the corridors of external consultations was implemented through DALI technology. In addition, in both areas as in the emergency rooms, wards and hospitalization blocks, LED lighting has been installed. These measures will entail a minimum saving of 10% on consumption prior to LIFE Smart Hospital.

Another of the measures that have been implemented in the framework of the Project has been the optimization of ventilation in the hospital’s operating rooms (17 units and two smaller operating rooms). According to current regulations, the air conditioning of these spaces must be performed under overpressure and with ventilation levels of filtered air 20 times per hour. In the framework of the Project, it has been reduced to 10 times the air renewal of operating rooms when they are not being used.

The air conditioning of the corridors has also been optimized. Before the LIFE project, the air conditioners were operated by heating in the winter and cooling the air passing through them in summer, according to set-up set-points in the return air. This form of operation demanded that the fans of the air conditioners work whenever the equipment was working, regardless of whether or not to bring heat or cold, which meant a useless energy consumption. In the framework of the Project, the necessary elements have been implemented to reduce the flow of air driven with greater thermal jump. Large savings are estimated, especially when the outside conditions are mild, such as autumn and spring.

Finally, within the energy axis, the project has changed the existing oversized HVAC engines to more efficient ones, which are in line with the actual demand curves.
