NEEDS

  • SAVE COSTS: The energy cost of a hospital is divided into different areas, the most4 important being climate control and lighting.
  • CONSUMPTION CONTROL: Control the consumption of the building in real time.
  • AVOID LOSSES: Analyze the characteristics of buildings and identify where the most important energy leaks. For walls, windows and roofs loses over 30% of energy.
  • INCREASE COMFORT: Make the temperature, humidity and air exchange to give a better sense of comfort to the user and the worker.

SOLUTIONS

3
  • MONITORING FACILITIES: For to know the distribution of consumption in real time from a hospital and real power used.
  • SURROUNDING IMPROVEMENT: Increase the insulation of facades and roofs, inside or outside. Changing old wooden windows and balconies  unsealed.
  • ADJUST TIMES AND CONSUMPTION: Avoid maximum power at certain times.Review contracted power.
  • REPLACE INEFFICIENT FACILITIES: Boilers with great energy demand, gas or electricity.

ACHIEVEMENTS
