The Life Cycle Assesment LCA is a method used to quantify the environmental impact of a product or service along their life cycle. The tool offered is based on the LCA and will provide an easier and a visual comparative report to assess the impacts generated by two different facade's construction solutions. The source of the results are feed from a database composed of data from the Environmental Product Declaration which is a mechanism used for environmental communication. The Environmental Product Declaration is the most prestigious and well recognized mechanism due to the objectivity incurred on the data collection process. The tool enables selecting various facade's configurations through the combination of different layers. It was decided not to evaluate the actual environmental impacts with the aim of building a decision making tool where the technician will be able to go in depth for the specific impact of each material and identify and approach the important focal points using the comparative report. The LCA simplified tools represent a compromise for a precise evaluation, but it will be necessary to be realistic and transparent about their limits as stated at the end of the paper.ResumenEl Análisis de Ciclo de Vida (ACV) es un método que sirve para cuantificar el impacto ambiental de un producto o servicio durante su ciclo de vida. La herramienta que se presenta pretende, basándose en este método, proporcionar de forma simplificada y visual un informe comparativo de los impactos que generan dos soluciones constructivas de fachadas. Los resultados se nutren de una base de datos formada por datos de Declaraciones Ambientales de Producto, mecanismo de comunicación ambiental que goza actualmente de mayor prestigio debido a la objetividad en el proceso de obtención. La herramienta permite seleccionar distintas configuraciones de fachada mediante la combinación de diferentes capas. Se ha decidido no ponderar los impactos con el fin de la herramienta sea un asistente de decisión, donde el técnico pueda profundizar hasta el impacto específico de cada material para poder identificar los focos graves de impacto y actuar en consecuencia, teniendo siempre como referencia el carácter comparativo del informe. Las herramientas de ACV simplificadas representan un compromiso en la precisión de la evaluación, pero es necesario sean realistas y transparentes respecto a sus límites, que se presentan al final del escrito.

Life Cycle Assesment is a method to assess environmental aspects and potential effects which are connected with product, process or service. This method is conducted by using compilation and data analysis on input and output of production system, evaluation of environmental potential effects, intrepretating on data compilation and analysis, and assessment results on effects due to the goal of LCA. The research was conducted at PT. Pagilaran – Samigaluh and aimed to implement LCA on tea product. It was done by direct observation on all process steps, from harvesting tea leaves until tranportation to final storage at manufacturing. The results showed that for producing one kilogram green tea at this factory it was needed energy 68,534.14KJ and released emmissions from fuel were 56.53 g CO2;7,07 g HC; 2,12 g NOx, and 0.053 g Pb. Emmission from processing steps were 18.37 ppmCO2; 321.31 ppm CO; 22.75 ppm HC; 93.08 ppm NOx; 15.17 ppm SOx and 0.12 g ash. Furthermore for transporting tea leaves some gases were released as follow 15.36 g CO;9.66 g HC; 65.46 g; NOx; 5.20 g SOx and 2.198 g ash. Keywords: Green Tea; Energy; LCA; Emissions
