Overview of identified insulation upgrade opportunities and projected annual savings.
Upgrading the insulation on the 189 identified items would result in estimated annual energy cost savings of $29,818/yr, a reduction in heat flow of 4,591,858 kBtu/yr, a reduction in CO₂ emissions of 303.39 MT/yr, and a reduction in NOₓ emissions of 1342.4 lbs/yr. All calculations were performed using the NAIMA 3E Plus (version 5.1) computer program.
Energy cost savings by system area, ranked by annual impact.
Emissions reductions achieved through insulation upgrades.

Project-specific inputs and calculation methodology.
All calculations performed using NAIMA 3E Plus (v5.1), based on ASTM C680 methodology.
Each item assessed in as-found condition. Bare surfaces have no insulation present.
Recommended upgrades include fiberglass, cellular foam, elastomeric, and ceramic fibre materials.
CO₂ and NOₓ calculated using EPA fuel-specific emission factors applied to energy saved.
