PRO-COMFORT: PROACTIVE SYSTEM FOR OPTIMISING ENERGY EFFICIENCY AND COMFORT IN BUILDINGS. THE PROJECT AIMS TO APPLY INFORMATION AND COMMUNICATION TECHNOLOGY TOOLS TO BUILDINGS, IN ORDER TO PRESERVE THEIR WELL-BEING INSIDE, WHILE REDUCING THEIR ENERGY CONSUMPTION. THESE ISSUES ARE OF GREAT INTEREST TO THE EUROPEAN COMMUNITY, WHICH HAS SET THE FOLLOWING TARGETS FOR REDUCING THE ENERGY CONSUMPTION OF BUILDINGS, RESPONSIBLE FOR 40 % OF ENERGY CONSUMPTION: 20 % BY 2020 AND 80-95 % BY 2050. THE IDEA BEHIND THE PRO-COMFORT PROJECT CONSISTS OF THE CREATION OF AN INTELLIGENT MONITORING AND CONTROL SYSTEM OF THE MAIN PARAMETERS OF THE INTERNAL ENVIRONMENT, CONSIDERED RESPONSIBLE FOR THE COMFORT OF PEOPLE, SUCH AS TEMPERATURE, HUMIDITY, CONCENTRATION OF CO2 AND POLLUTANTS IN THE AIR
