Title: Assessment Of Energy Efficiency Measures Recommended for Industrial Facilities: Environmental, Economic, And Life Cycle Perspectives
Abstract: This study evaluates the economic, environmental, and life cycle impacts of over 800 Energy Efficiency Measures (EEMs) implemented in Nebraska manufacturing facilities. These EEMs require minimal structural changes and can be rapidly deployed. Financial analysis includes utility savings, implementation costs, and payback periods, while environmental assessment covers net cost and cost per ton of CO₂-equivalent reduced. Insulating hot pipes and buildings, using HVLS fans, and adding economizers to boilers were among the most cost-effective and sustainable options. Lighting upgrades and leak detection also showed strong GHG reduction. However, motor and boiler replacements, especially when done prematurely, were less effective. Life Cycle Assessment (LCA) revealed that while most EEMs reduced Scope 1 and 2 emissions, some led to burden shifting due to material-related embodied emissions from new equipment installations.
