Resumen
THIS PAPER PRESENTS RESULTS ON ENERGY AND ENVIRONMENTAL IMPLICATIONS OF CONSTRUCTION OF A STANDARD SOCIAL HOUSE IN CHILE. A SIMPLIFIED LIFE CYCLE ASSESSMENT APPROACH WAS USED HERE, IN ORDER TO IDENTIFY ENVIRONMENTAL IMPACTS AT DIFFERENT STAGES IN THE BUILDING LIFE CYCLE UNDER SPECIFIC CHILEAN CONDITIONS. ONE SQUARE METER OF A STANDARD HOUSE WAS USED AS THE FUNCTIONAL UNIT, AND ENERGY CONSUMPTION AND MATERIAL REQUIREMENTS WERE RECORDED FOR ALL STAGES. THE CARBON FOOTPRINT OF THE CONSTRUCTION PHASE WAS ALSO ESTIMATED.
THE SYSTEM LIMITS INCLUDED ALL ENERGY REQUIREMENTS RELATED TO THE MANUFACTURING OF BUILDING MATERIALS USED IN FOUNDATIONS AND ENCLOSURES, CONSTRUCTION AND THE HOUSE USAGE PHASE. DECONSTRUCTION OR END OF LIFE PHASES WERE EXCLUDED FROM THE SYSTEM LIMITS UNDER STUDY.
RESULTS INDICATE THAT ENERGY CONSUMPTION DURING THE HOUSE CONSTRUCTION PHASE COULD BE NEGLECTED AS COMPARED WITH REQUIREMENTS IN OTHER LIFE CYCLE STAGES. ADDITIONALLY, MANUFACTURING OF HOUSING FOUNDATIONS AND BRICKS ACCOUNTED FOR MOST OF CARBON FOOTPRINT.
