Heating, ventilating and air conditioning systems in hospital operating theatres consume high amounts of energy, operate for long periods of time and provide high performance. For this reason, it is necessary to study their energy consumption and determine sustainable solutions that optimize their operation and improve their performance. In this paper, annual thermal energy consumption of a conventional operating theatre is evaluated. Potential energy savings is evaluated by maintaining an adequate indoor environmental quality for these rooms. In addition, how to minimize energy consumption depending on the air renewal flow rate used and installing a sensible heat recovery system was studied. Results show that energy demand of an operating room is reduced by 24.1% by recirculating 25% of air flow extracted from the room. Energy cost decreases 44.31% by increasing the recirculated air flow rate to 50% of the air flow extracted from the room.

“…Given that maintenance management is well-known to influence energy consumption in hospitals [16], the workload associated to medical gas installations as compared to that of the global maintenance of the building was estimated [36]. For such purposes, the maintenance records of the hospitals under study were analysed within the period 2012-2016.…”

Abstract:Medical gases are known to show a great environmental impact and also to consume relevant resources in terms of hospital management. The present work reports on a study performed between 2008 and 2016 in a target set of 12 Spanish hospitals with floor area and number of beds ranging 2314-23,300 m 2 and 20-194, respectively, for which the average annual consumption rates of oxygen, nitrogen, medicinal air, carbon dioxide and nitrogen protoxide were analysed. The annual consumption of medical gases in a hospital was proved to be correlated with the number of hospital discharges, the number of surgeries, the number of emergency interventions, the number of hospitalisations, the number of hospital beds, the useful floor area of the building and the number of workers. In particular, the annual consumption per hospital bed was computed as 350 m 3 for oxygen, 325 m 3 for medicinal air, 9 m 3 for nitrogen protoxide and 3 m 3 for carbon dioxide. It is shown that healthcare activity appears as an adequate variable to quantify and to monitor medical gases consumption in hospitals, to assess the size of their facilities as well as to optimise maintenance management.

“…The annual consumption of DHW per bed in hospitals ranges from 29.2 to 47.45 m 3 /bed in Europe [22] and from 36.5 to 54.75 m 3 /bed in the USA [23]. In Greece, the same variable ranges between 32.85 and 43.8 m 3 /bed [24].…”

Abstract:The aim of this paper is to quantity the annual average consumption of water in 13 public hospitals in Extremadura (Spain). An analytical study in order to reduce water demand was conducted from 2010 to 2014 in the above-mentioned hospitals. The study concluded that, in order to determine the average annual water consumption, a fixed ratio is not the appropriate tool. A parametric type related to the built surface area and/or number of beds by hospital should be used instead. The average annual consumption of cold water for human consumption ( The ratio between DHW and CWHC was 35.62% (5.53). The time period of greatest demand was between 12 p.m. and 6 p.m. Considering B as the number of hospital beds and S its built surface area, to calculate the average annual cold water for human consumption in a hospital, the equation 165B + 12,100 (m 3 ) or 1.568S + 2400 (m 3 ) should be used. Similarly, in terms of hot domestic water, the average annual consumption in m 3 corresponds to either 53.65B + 5170 (m 3 ) or 0.53S + 1400 (m 3 ).
