Resumen
ENERGY SAVING IS A VERY ACTUAL TOPIC IN CHILE. THERE ARE TWO DIVERGENT REALITIES IN THE CONSTRUCTION SECTOR: ON THE ONE HAND AN INADEQUATE INDOOR COMFORT AND ON THE OTHER HAND, VERY HIGH ENERGY CONSUMPTION. BOTH ARE PRODUCTS OF A LOW BUILDING QUALITY. THIS ARTICLE SHOWS THAT IT IS POSSIBLE TO SAVE ABOUT 80% OF ENERGY IN SPACE HEATING AND COOLING IN THE CENTRAL-SOUTH AREA OF CHILE, WITH LOW ENERGY BUILDINGS WHICH REACH THE SO-CALLED PASSIVE HOUSE STANDARD. USING THIS STANDARD NOT ONLY REDUCES THE ENERGY DEMAND OF BUILDINGS BUT ALSO INCREASES ITS INTERNAL COMFORT CONDITIONS. A PARAMETRIC STUDY WAS UTILIZED IN ORDER TO ANALYZE, BY WHAT MEANS IT IS POSSIBLE TO MEET THE STANDARD IN THREE CITIES IN CENTRAL-SOUTH OF CHILE. THE TECHNOLOGIES TO BUILD PASSIVE HOUSES, SUCH AS HIGH THERMAL INSULATION, DOUBLE GLAZING WINDOWS WITH LOW-E COATING AND ARGON FILLING OR VENTILATION SYSTEMS WITH HEAT RECOVERY ARE ALREADY AVAILABLE IN THE MARKET. WITHOUT DOUBT, THE BUILDINGS THAT ACHIEVE THE PASSIVE HOUSE STANDARD HAVE AN HIGHER INITIAL INVESTMENT COST THAN A TRADITIONAL BUILDING, BUT ON THE OTHER HAND, A PASSIVE HOUSE HAS APPROXIMATELY 80% LOWER RUNNING COSTS THAN A TRADITIONAL BUILDING. DUE TO THIS SAVING IN OPERATING COSTS, IT IS POSSIBLE TO ECONOMIZE THE HIGHER INITIAL COST DURING THE LIFETIME OF THE CONSTRUCTION.
