PR Number: 0040670448

1. General Information

1.1 Little Pend Oreille National Wildlife Refuge (NWR) requires replacement of two propane-powered furnaces and accompanying AC units that service the headquarters office.

1.2 The existing furnaces and AC units are inefficient aged beyond their functional lifespan. Furthermore, these units consume only propane and do not have electric capabilities, creating unnecessary carbon emissions from servicing the headquarters office. These units were among several inefficiencies identified in a recent energy audit.

Current systems are comprised of the following:

System 1:

• Air Conditioner: (Trane)

• Model No.: TXC036C4HPB1

• Serial No.: K03748835

• Furnace: (Inter-City Products)

• Model No.: NUGS075BG04

• Serial No.: L934667573

System 2:

• Air Conditioner: (Trane)
