Building Envelope Rebates

Roof and Ceiling Insulation
Roof and ceiling insulation reduce cooling loads and expenses. They also increase comfort for building occupants.

Ceiling Insulation Rebate Requirements
	The existing ceiling and roof system must have an overall R-value of R-11 or less to qualify.
	The insulation added to the ceiling system must be R-8 or greater.
	Blown-in or loose-fill insulation placed above a lay-in ceiling does not qualify.
	Air conditioning supply and return paths located above the ceiling must be ducted.
	Furr-down and knee wall cavities must be insulated.
	The area where insulation or a roof coating will be added must be over a mechanically cooled space.

Roof Insulation Rebate Requirements
	The existing roof system must have an overall R-value of R-11 or less to qualify.
	The insulation must be installed between the roof surface and the conditioned space.
	The insulation added to the roof system must be R-8 or greater.

Reflective Roof Coating
Reflective roof coatings are sprayed-on coatings or applied membranes that reflect incoming solar radiation. They greatly lower the surface temperature of the roof and the heat penetrating the building. The results are energy savings and greater comfort.

Reflective Roof Coating Rebate Requirements
	Existing roof must not be a reflective roof.
	The reflectiveness of the coating or the integrated, white, single-ply membrane must be measured by test methods ASTM E424-71, E903-96, C1549-04, E1918-97 or a solar spectrum reflectometer and have a minimum reflectivivity of 75%.
	Austin Energy must perform a pre-inspection. The Rebate Application must be submitted before the new roof is applied. At the time of the final inspection, the customer must provide: 1) an invoice, 2) warranty statements, and 3) the manufacturer’s product information (stating the rated R-value and if it was manufactured without CFCs). For reflective roof coatings, submit the ASTM test result data verifying the 75% reflectivity.

Window Coverings - Solar Screens/Solar Film
Solar heat radiates through windows and roofs. It decreases comfort for building occupants and increases the need for air conditioning. Window treatments such as window film or solar screens can reflect up to 80% of incoming solar heat.

Window Coverings - Solar Screens/Solar Film Rebate Requirements
	Rebates are paid on the actual square footage of glass that encloses an air conditioned space.
	Austin Energy must perform a pre-inspection of the existing glass.
	The Rebate Application within must be submitted before the window treatment is applied. At the time of the final inspection, the customer must provide: 1) an invoice, 2) labor and materials warranty statements, and 3) the manufacturer’s product information stating the rated shading coefficient.
	Eligible windows can be clear or factory tinted, single or double-pane and shaded no more than 50% by exterior shading during the months of May through October.
	Windows with existing deteriorated film will be eligible for rebates under the tinted glass category.
	Eligible window orientations are south, east, west, southwest, southeast and northwest.
	The treatment must be permanently affixed to the glass (film) or window frame (screen).
	The treatment must have a shading coefficient rating of 0.45 or less.
	The installation must be warranted for one year and the materials for five years.
