Use this Excel document as a design, specification and pre-ratingsubmittal tool.Consult with your Rater and the "Guide to the Single-Family Rating 2013" for help.Basic Requirements must be met for all Ratings for new construction. Exceptions may be made for renovations. 2. When starting the design please begin the online rating process. 3. You will be charged a service fee of $50 for each rating. After an online rating application has been accepted, you will be sent an invoice.You must make payment to Austin Energy before your rating can be completed. 4. If your project is located outside the AE service area but is inside the Extended Rating Area:You must work with an Extended Area Rater (see www.greenbuilding.austinenergy.com for information).Use the online rating, just as for ratings in the AE service area.Not FulfilledBR + 4-Star Requirements + pointsSquare feet per ton of coolingBasic RequirementsBR + 2-Star Requirements + points BR + 3-Star Requirements + pointsTotal Points0BR + 5-Star Requirements + pointsPRESCRIPTIVEBasic Requirements (BR) Place an x in each yellow box at left and fill in other relevant yellow cells.

Equipment installed must match calculation.bIf correct Manual J calculation results in fewer than 600 sf of living space per ton of cooling, the design is inappropriate for Central Texas and the home will not be rated.cHomes for which split systems are too large (approx. <900 sf) must be equipped with a mini-split or other appropriate system. dHome design and construction must accommodate the selected equipment and the correctly sized and insulated ductwork.eSubmit full Manual J and D Report with equipment specified; split-system equipment must be an AHRI match.fSubmit AHRI certificate for split system installed.
