Hospitals are centres characterised by having an increasing demand of resources over the years, either due to the high volume of people stopping by on a daily basis, or to the growth of machinery and technology used to carry out their activity, so laying emphasis on a better use of such resources needs to be a main objective if the category of “green or sustainable hospital” wants to be reached.

The idea of promoting “sustainable hospitals” arises from the huge waste of resources, and aims for the most part to relieve the environmental impact of such effect, turning them into eco-friendly and environmentally sustainable institutions.

When fulfilling the category of “green hospital”, a variety of measures can be applied, but almost all of them have to do with reducing consumption coming from non-renewable energies, increasing in this way the use of clean energies, diminishing the generation of residues harmful to the environment, and ensuring and enhancing service quality, as well as that of user’s comfort, wellness and safety.

Measures allowing the promotion of sustainable hospitals

There is a set of required measures when it comes to achieve sustainability in hospitals. Some of them are simplicity itself while others demand higher capital investment. But all of them, besides being environmentally friendly, entail important savings in economics in the medium to long term.

  • Use of natural lighting and ventilation.
  • Maintenance and regular revision of boilers and HVAC systems.
  • Installation of energy efficient lighting or LEDs, as well as installation of sensors to detect human presence in those areas with a moderate people flow.
  • Use of electronic equipment provided with energy-efficient systems.
  • Use of renewable energies such as solar, geothermal, biomass and rainfall water.
  • Thermal insulation of façades and roofs by means of repairing cracks and fissures, by injecting building insulation materials within cavity walls, use of waterproofing membranes, etc.
  • Substitution of obsolete electronic equipment and HVAC systems as well, with others in fashion and with the energy certification classified as Type A.
  • Substitution of window frames for others with a thermal bridge breaking system, as well as installation of double glazed windows in order to avoid thermal exchanges between the interior and exterior.
  • Recycling materials, as well as increasing the use of materials coming from recycled sources.
  • Substitution of manual or traditional doors with automatic doors. This is an issue of major importance since hospitals are places with a high amount of people flow. Through the installation of automatic doors, not only building air tightness will be improved, but also thermal transmittance will be avoided to a large extent since these doors will remain open only at the necessary time.
  • Installation of hermetic automatic doors in surgical areas, that will enable to maintain the pressure required in clean environments, thus avoiding the energy waste that inadequate insulation entails.

Green or sustainable hospitals open the door to a healthier lifestyle for people who make use of them as well as for environment.
