OBJECTIVE Evaluate the applicability of the LCA technique in the measurement of the eco-efficiency of public lighting projects.

ANALYZE OF ECO-EFFICIENCY

CONCLUSIONS • Public lighting project can be analyzed comparatively by the concept of

ecoefficiency; • Use of a single indicator for economic performance (such as NPV) and A

single indicator for environmental performance (such as equivalent CO2 emissions), was effective as a measure of the eco-efficiency;

• Eco-efficiency in the management of public services does not necessarily present only economic advantages, but can carry out the responsibility of the manager towards the citizen;

• The work can be improved with a refinement of the technique, mainly with respect to the valuation of the environmental aspects in the part of the economic evaluation and definition of the cash flow.

Contribution ID 339 Poster Presentation Number P-59

METHOD Functional Unit: "Efficiency of 561,490 existing public lighting points, with a forecast of expansion to 637,490 in five years, including its operation, with the minimum quality required in the standard ABNT NBR 5101: 2012 (brazilian norm), for 20 years."
