Mechanical Insulation Appraisal · Preliminary Report

Minnesota Veterans Home - Bldg. 1

Engineered findings from a NAIMA 3E Plus walk-down assessment. 19 items inventoried across 5 systems · estimated $1,991/yr in recoverable operating cost.

Executive Summary

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 it's completion. All completed upgrades will have a Quality Control visit to ensure the Mechanical Insulation was installed in accordance with specifications.
