Energy Efficiency & Quality Assurance Department
Engineered findings from a NAIMA 3E Plus walk-down assessment. 303 items inventoried across 53 systems · estimated $32,786/yr in recoverable operating cost.
Overview of identified insulation upgrade opportunities and projected annual savings. This is a Preliminary Report. Please see the 'Line Item Detail' Page for detailed information about each item assessed along with Infrared Imaging. Your EEQA representative will now solicit bids from our Qualified Contractors. Please allow 4-6 weeks for the bidding to complete. Your EEQA representative will then submit to you a Final Report upon its completion. All completed upgrades will have a Quality Control visit to ensure the Mechanical Insulation was installed in accordance with specifications.
Upgrading the insulation on the 303 identified items would result in estimated annual energy cost savings of $32,786/yr, a reduction in heat flow of 3,261,946 kBtu/yr, a reduction in CO₂ emissions of 215.52 MT/yr, and a reduction in NOₓ emissions of 955.1 lbs/yr. All calculations were performed using the NAIMA 3E Plus (version 5.1) computer program.

Project-specific inputs and calculation methodology.
Fuel cost is a preliminary planning value; it will be confirmed against the facility's actual utility rate before the Final Report. All dollar figures scale proportionally with this input.
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 upgrade materials specified for this facility: Concrete, Knauf Earth Wool 1000F Pipe Insulation. See the Line-Item Detail for per-item specifications.
CO₂ and NOₓ reductions are computed from fuel energy saved using the NAIMA 3E Plus v5.1 default emission factors for natural gas: 116.53 lb CO₂ and 0.23373 lb NOₓ per 106 Btu of fuel input. The default NOₓ factor corresponds to uncontrolled combustion; actual NOₓ reductions depend on the installed burner class and may be lower for low-NOₓ equipment.
A single ambient temperature of 72°F was applied to all items, including those located in mechanical tunnels. Tunnel spaces typically operate above room ambient, which would reduce the temperature differential and the calculated savings on those runs. Measured per-location ambients can be applied in the Final Report.
