Scope and Goal

The scope of this Life Cycle Assessment (LCA) encompasses a comprehensive evaluation of the environmental ramifications associated with the constituent elements of ‘Offshore Wind Farms and Building Systems that manage it’. This appraisal extends across the entirety of their life cycles, spanning from the extraction of raw materials to their ultimate disposal, except for the dismantling phase, which remains excluded from consideration.

Specifically, the assessment delves into the environmental footprint associated with various components, notably including the structural Columns of the building, the HVAC (Heating, Ventilation, and Air Conditioning) system therein, the Pavement contiguous to the building, and the Offshore Wind Turbines tasked with electricity generation. The delineated boundaries of this assessment are visually depicted in Figure 1, elucidating its objectives and parameters.

 

 

 

Life Cycle Inventory

The Life Cycle Inventory (LCI) constitutes a fundamental facet of the Life Cycle Assessment (LCA) framework, pivotal for assembling comprehensive data pertaining to the inputs and outputs across the entirety of a system’s life cycle. This entails meticulous documentation of the extraction and processing of raw materials, transportation logistics, production processes, utilization patterns, maintenance requisites, and the fate of materials through disposal or recycling channels.

Within our LCI framework, a detailed catalogue is provided delineating the resources utilized within each model and system across various scenarios. Moreover, it meticulously records emissions of key pollutants such as carbon dioxide (CO2), nitrogen oxides (NOx), and sulfur dioxide (SO2) emanating from each system, alongside cost assessments. This wealth of data serves as a valuable tool for pinpointing areas ripe for intervention and improvement, thereby facilitating the mitigation of environmental impacts associated with product or system deployment.

For precise reference, Table 1 below encapsulates the granular details of our scenario in LCI.

 

 

Main system: Offshore Wind Farms and Building Systems that manage it

1) Column: Reinforce concrete

2) HVAC system: Chiller

3) Pavement: Asphalt

4) Offshore Wind Farm: Blade

 

The table 2 represent the Result of LCA. It calculates the overall LCA’s impact on the environment, energy consumption, and emissions of CO2, NOx, and SO2, which are major contributors to the global warming issue.
