NEEDS
- SAVE COSTS: The energy cost of a hospital is divided into different areas, the most
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

-
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

- PRESTIGE: Company is committed to the environment and energy saving.
-
ECONOMIC SAVING: Reducing expenses by 50%.
-
REVALUATION: Increase the heritage value.
