Abstract

The purpose of this article is to estimate the economic and environmental impacts of energy consumption derived from healthcare buildings and proposes several energy-saving options in the sector. An experimental energy consumption study was development between 2005 and 2013 in 12 hospitals and 70 healthcare centres in Spain, built between 1980 and 2005 through audits carried out between 2005 and 2012, performed by the Extremadura Energy Agency. The study focused on electric energy, HVAC, DWH, lighting systems, renewable energies, maintenance strategy, thermal insulation, and optimal building size. Specifically, the following parameters were evaluated: energy savings, investment emission of CO2, NO2, and SO2 gases, and payback. The results revealed that through an appropriate energy management of healthcare buildings it is possible to save up to 8.60 kWh/m2 per year, for buildings of less than 5000 m2 (with no beds), which represents an expense of 1.55 €/m2. In healthcare buildings larger than 5000 m2 (with beds), it was possible to save up to 6.88 kWh/m2 per year, which represents an expense of 1.25 €/m2. View Full-Text
