Section/Table/Figure Number: 4.4.2 Determining Irrigated Area for the Reference Home

Comment Intent: Objection

Comment Type: Editorial

Comment:

The language in the text leading to Eq 4.4-2a and Eq 4.4-2b makes an odd distinction without apparent purpose. The first refers to a “one- or two-family dwelling” while the second is a “detached or duplex dwelling”. The rest of the descriptions makes what appears to be the real distinction, i.e. whether the lot size is above or below a specific threshold.
I suggest using the “one- or two-family dwelling” language for both entries, since it encompasses single-family detached, townhome, and duplex homes.

Proposed Change to Amendment:

4.4.2 Determining Irrigated Area for the Reference Home. Reference Home Irrigated Area shall be calculated as follows:

Where the Rated Home is a one- or two-family dwelling and the lot size of the Rated Home is less than 7,000 ft2, the Irrigated Area of the Reference Home shall be calculated as follows:

(Eq 4.4-2a)

Where the Rated Home is a detached or duplexone- or two-family dwelling dwelling and the Lot Size of the Rated home is greater than or equal to 7,000 ft2, the Irrigated Area of the Reference Home shall be calculated as follows:

(Eq 4.4-2b)

Where:

Ref_Irr_Area= The size of the landscape that receives supplemental water in the Reference Home

Lot_Area= The size of the lot on which the Rated Home is being constructed

For multi-family building properties, the irrigated area for the Reference Home shall be the same as the Rated Home irrigated area.
