Florissant City Hall — Energy Audit Report

Executive Summary

Overview of identified insulation upgrade opportunities and projected annual savings. This is a Preliminary Report. 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 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.
