Through this work we intend to make an analysis of the life cycle of a project about the process that is developed, exposing each step in a detailed way, which corresponds to a process of transformation of ideas arising from the detection of needs or problems in concrete solutions for the provision of goods or services that best solve those needs or problems.
Taking into account current trends and the accelerated pace of life of modern society, which focus on producing, consuming and discarding. Based on these processes and / or activities, environmental impacts are generated that consume resources, emit substances harmful to the environment that in turn generate other environmental impacts in the course of their life cycle.

For this reason, it is very important to assess the environmental impacts caused and also those that influence climate change, the effects on the reduction of the ozone layer, eutrophication, acidification of water, among many other factors.
The analysis of the life cycle, corresponds to an important tool in the identification of the impacts caused in the production of a product since it covers from its beginning to the end including the stages where it is terminated.

The analysis of the life cycle

ISO 14040 defines the Life Cycle Analysis (LCA) as a technique to determine the environmental aspects and the potential impacts associated with a product, by carrying out an inventory that involves important inputs and outputs of the system, in order to evaluate the environmental impacts potentials associated with these, and at the same time analyze the results obtained from the stages identified in the inventory and / or the impacts that are related to the objectives of the study "

Life cycle analysis - LCA, being able to help; "The identification of opportunities to improve the environmental performance of products at different stages of their life cycle, the provision of information to decision-makers in the industry, governmental or non-governmental organizations (for example, for planning strategic, the establishment of priorities, the design and redesign of products or processes), the selection of relevant environmental performance indicators, including measurement techniques and marketing (for example, the implementation of an environmental labeling scheme, the preparation of an environmental declaration or an environmental product declaration) ".

Life Cycle Analysis of Distributed Energy System Projects’ Energy Consumption and GHG Emission

Objective: Which aims to perform an LCA (acronym in English through) according to "the method of Life Cycle Analysis (LCA) to assess the energy consumption and GHG emissions of projects of the Distributed Energy System, the project of the Natural Gas Distributed Energy System of China Brewery Snow Breweries.
Scope: Designed another 5 cases with different energy pathways to compare their energy consumption and emissions performance. The result shows that the All Natural Gas project saves 8% of energy and reduces GHG emissions by 38% compared to the traditional project that uses coal and electricity from the grid. "(Hansi, Xiongwen, & Xunmin, 2017)
Inventory analysis: Analyze the life cycle energy consumption and the emission of greenhouse gases from the multiple types of projects of the distributed energy system with different energy supply routes, with one output (electricity, heat and cooling) kept constant, the Fuel energy consumption is calculated given efficiency factors.
Impact evaluation: derived from the consumption of life cycle energy and the emission of greenhouse gases through the following 3 steps;
Step 1: Convert the output to the energy input, as shown in equation (1) mijk = Σ yo Y ijk / do ijk
Step 2: Use the energy input to calculate the life cycle energy consumption and the emission of greenhouse gases based on the old literature, as shown in equations (2-3)
LCk = Σ j mijk * una j      (2)
GEI k = EM CO2 + 23EM CH4 + 296EM N2O = mi jk * segundo j    (3)
Step 3: Calculate the energy savings and the emission reduction rate by comparing case k and based on the previous case results k ', as described in Equations (4-6).
RE = Kk ' 1-Σj mijk / Σ j mi jk'     (4)

RLC = Kk ' 1-LC k / LC k'    (5)

RGHG = Kk ' 1-GHG k / GEI k'   (6)

Interpretation: We rely on the data in the literature to obtain the results. To examine if our results are robust, we did the sensitivity analysis focusing on the COP cooling, and the efficiency of the boiler. As Fig. (1) shows the CP does not make a difference in the performance of the projects of the distributed energy system. However, when the efficiency of the boiler is willing to be 60%, a more modest figure, the realization of projects based on natural gas as the base case is even more exceptional.

Conclusions

The project we are investigating has an outstanding performance in energy saving and emission reduction.

When comparing the case with coal and electricity of the grid, the project of the Distributed Energy System based on gas saves 8% of energy and reduces GHG emissions by 38% in a Life Cycle.

Renewable energy

The technology offers alternatives to reduce GHG emissions. Due to the project environment, solar energy can hardly improve performance. However, it is possible to use biomass (byproduct of beer production) or wind energy in the distance to improve the system. Therefore, it shows that renewable energy technology, especially the integrated use of biomass and wind energy, has great potential in the development of Distributed.

The article explains the following:

The Energy System projects have been on a fast track. The Distributed Energy System is an important part of China's 13th five-year plan. The support of policy makers makes the number of Distributed Energy

The distributed energy system is still in a "learning by doing" stage, especially in China. The space between current projects and best practices makes the evaluation of Distributed Energy System projects important.

4. LA FASE DE INTERPRETACIÓN

The project of distributed energy system based on base gas has a desirable performance in environmental value. Compared to the traditional project, the Energy System project Gas-based distribution seems to use 7% more energy as an input, but in view of the Life Cycle, it reduces energy consumption and GHG emissions significantly ( 8% and 38% respectively). In a comparison with the case where electricity is purchased from the grid, it has an even greater advantage. Renewable energy has the potential to develop in the future. Limited by solar resources in Sichuan Province, the distributed energy system project based on solar energy has a positive but limited effect on energy savings and emissions reduction.

Through this work we could make an approach to the life cycle analysis (LCA) and its different phases for its application. By means of the meticulous study of the article and technical norms object revision in the unit 3, of the phase 4 of the training course.
The support material served as a self-management instrument to address the requirements established in the course guide, through the analysis of the life cycle (LCA) of the productive sector that for this specific case revolved around the Natural Gas distributed energy system. in China.
As learning outcomes of the activity, the appropriation of sustainable development concepts was achieved through the study of a real case, knowledge of the Colombian technical standards that define the ecological criteria for life cycle analysis, the use of tools of type technology such as Padlet, the appropriation of the English language and the promotion of collaborative work.
Taking into account current trends and the accelerated pace of life of modern society, which focus on producing, consuming and discarding. From these processes and / or activities important impacts are generated, and for this reason it is of great importance to assess the environmental impacts caused and also those that influence climate change, the effects on the reduction of the ozone layer, eutrophication , the acidification of waters, among many other factors. The analysis of the life cycle, corresponds to an important tool in the identification of the impacts caused in the production of a product since it covers from its beginning to the end including the stages where it is terminated.
In conclusion, if a company wants to endure competitively in the market, it must present in the best way each phase of the life cycle of the projects, defining clear objectives, detailed budgets, and terms of reception. Just as it is very important to carry out a previous study in which possible obstacles are detected and to solve them and finally provide the adequate follow-up throughout the project.
