Weatherization involves a number of individual measures aimed at improving the insulation levels, and efficiency of a building, in this case a single-family home.  For this measure it refers to installation of envelope improvements that include attic insulation, wall insulation, floor insulation, prime window replacement, window efficiency upgrades, and infiltration reduction.
