“…Table 3 shows the average annual consumption of energies in this complex. Considering the total hospital complex area of 77300 m 2 , the specific total energy consumption of nearly 250 kWh/m 2 /year is obtained which fits within the corresponding data span in hospitals worldwide [26] - [29]. Unlike many other studies that strive to propose and implement measures for heat consumption reduction generally, this study is focused on the natural gas solely.…”

“…Opportunities for energy consumption decrease in public health are tightly connected with the end use of energy in this sector. Nearly half of the energy consumption is typically consumed for building heating [20], [26], [32], followed by HVAC systems, lighting and other electric appliances. Thus, the majority of studies aimed at energy intensity decrease in this sector seek to lower the heating demands by proper building envelope retrofit, central heating unit upgrade, HVAC system modernization and regulation system improvement [4], [5], [33] - [35].…”

“…Parallel in-house activities aimed at personnel education have the potential to aid these processes [36]. Environmental effect of decreased energy consumption is dual: lower emissions released to cover the energy demand [26], [35] and improved working and living environment [40].…”

A study on natural gas saving and emissions decrease in the public health care sector is presented. The analyzed hospital complex belongs to the largest ones in Slovakia and uses both hot water and water steam for heating purposes. Visual steam system inspection revealed serious inefficiencies, including steam venting, missing pipelines insulation and obsolete steam sources with dysfunctional blow-down system. Defined experiment with stepwise steam appliances shutdown enabled quantification of excess natural gas consumption due to these inefficiencies. Measures proposed for the solution of this state are inexpensive, with a short payback period. The expected natural gas savings amount up to 3200 MWh/year, which represents roughly 50% of the total natural gas consumption in the hospital complex.

Hospitals generate a high amount of carbon dioxide emissions into the atmosphere compared with residential and commercial buildings. Therefore, it is necessary to quantify and identify the CO 2 emissions derived from energy consumption in hospitals, studying their relationship with functional variables. The aim of this article is to analyze the CO 2 emissions derived from the hospital energy consumption. In Spain, 14 hospitals were analyzed, studying the built surface area and the number of beds in the period 2010-2014. The results showed that in a hospital, the average annual CO 2 emissions divided by built surface area is around 0.10 Ton per m 2 , and the annual CO 2 emissions divided by number of beds is around 13 Ton per bed. These ratios will make it possible to benchmark hospital management and set targets for limiting emissions into the atmosphere.
