Phase 4-Mural of Environmental Management by Milena Urbano https://padlet.com/milenaurbano3/yhcn9hvywh7s Collaborative work en-us 2019-06-05 03:08:40 UTC 2026-03-12 08:50:15 UTC hello@padlet.com Milena Urbano/ Environmental management for sustainable development . milenaurbano3 https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/365749261 Its objective is to achieve an adequate balance for economic development, the conservation of the environment, the rational use of resources and the growth of the population.
LIFE CYCLE ANALYSIS (LCA)
It can be identified as the methodological framework used to estimate and evaluate the environmental impacts that are attributed to a product or service during all stages of its life, it is important to recognize that all activities or processes cause the environment:
Resource consumption
Emission of substances
Generation of environmental changes during his life.
These impacts influence:
Climate change, reduction of the ozone layer, generation of ozone, acidification, which in turn negatively affects the environment.]]> 2019-06-05 03:27:13 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/365749261 Solandria González/ solgous https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/365997776 a) Phase of definition of the objective and scope
In this paper, relate an analysis life cycle energy consumption and GHG emission of multiple types of Distributed Energy System projects with different energy supply pathways. 
With output (electricity, heat and cooling) held constant, the fuel energy consumption is calculated given efficiency factors, and then life cycle energy consumption and GHG emission can be derived using LCA.
  • Case Design
They designed 6 cases to better capture the potential development of Distributed Energy System
projects as Table 1 shows. Case 1 (All NG) is the base case. China Resources Snow Breweries Distributed Energy System project operated in this model. They
compared All NG case to traditional coal fired projects with electricity bought from the grid or generated by private owned power plants. They also investigated the efficiency of renewable technology by comparing several cases with renewable energy and the case with electricity bought from the grid. Considering the location of the project where wind and solar power is relatively scarce and vine lees is easy to get.

When compared with traditional project, gas based reduces energy consumption and GHG emission significantly (8% and 38% respectively). Compared with case when electricity is bought from the grid, it has even greater advantage. Renewable energy has the potential to develop in the future. Constrained by solar resources in Sichuan province, solar based Distributed Energy System project has positive but limited effect in energy saving and emission reduction.]]> 2019-06-08 00:34:26 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366446863 Laura V. Gómez/.. laurisgomezhoyos https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366452588 d. Interpretation phase
The project we researched has outstanding performance in energy saving and emission reduction. Comparing the case using coal and grid electricity, gas based Distributed Energy System project saves 8% energy and reduced GHG emission by 38% in a Life Cycle Analysis view.
Renewable energy technology provides alternatives to reduce GHG emission. Due to the environment of the project site, solar energy can hardly improve the performance. However, it’s possible to utilize biomass (byproduct of beer production) or wind power in the distant to improve the system.

IPCC data to calculate the calorific value of natural gas (8900 Kcal / M 3), and other data used in stage 1 of input conversion as presented in Table 2.
The acquired data and In case 4 and 5, it was assumed that the energy of the biomass is modeled how much can be used in the Distributed Energy System Project. In case 4, the electric energy provided by solar energy was calculated, in addition to the network. In case 5 the project ensures that the biomass energy can cover the electricity demand and the cooling load.
In addition, the energy consumption of the life cycle and the emission of greenhouse gases from the multiple types of projects of the distributed energy system with different energy supply routes were analyzed, such as:
With the production (electricity, heat and cooling) they remain constant, the energy consumption of the fuel is calculated according to the efficiency factors, and then the energy consumption of the life cycle and the emission of greenhouse gases can be derived using the ACV results from the previous literature.
In addition, energy consumption of the life cycle and energy consumption are derived from GHG emissions through 3 steps that are detailed in the research method.

The projects in China are characterized by being interesting, unique and also by having the support of the government, which works together with researchers to promote distributed energy projects. In this document, researchers seek to analyze the energy consumption during the life cycle and the emission of GHG from multiple types of projects of distributed energy systems with different energy supply routes.
To obtain the energy consumption of the life cycle and the emission of GHG, the following steps must be carried out:
Step 1: Convert the output to power input
Step 2: Use the energy input to calculate life cycle energy and GHG emissions
Step 3: Calculate the energy savings and the emission reduction rate.]]> 2019-06-09 03:04:23 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366531710 https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366575653 2019-06-09 17:54:06 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366575653 https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366576205 2019-06-09 18:00:31 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366576205 https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366580328 2019-06-09 18:55:54 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366580328 https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366585285 2019-06-09 19:55:00 UTC https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366585285 Bibliografía https://padlet.com/milenaurbano3/yhcn9hvywh7s/wish/366586433
