Features of LCCA There are often multiple stages from start to finish Ignoring one or more stages can lead to false conclusions about benefits and costs This is particularly the case for complex variables that you wish to measure (greenhouse gas emissions for example) Alternatives may appear the same if multiple phases are ignored 10/12/10 8

Example: Solar Panels http://www.solarcentresuk.com/solar-power-payback.html Cheaper energy consumption from renewable solar energy source But costs energy to make! Need to include the full life cycle for proper comparison: Energy from producing aluminum, copper, glass, insulation, selective coating, other materials: 723.1 kWh Energy from manufacturing a single panel from the materials: 45 kWh
