**INSTRUCTIONS**

1\. No deduction will be allowed if it is determined by qualified
engineering or facility management personnel that the subject quarter
meets or exceeds the construction, weather proofing and energy-efficient
requirements recommended by local or national building codes for the
area in which the quarter is located.

2\. If the quarter is air conditioned, the quarter must lie in the
official "air conditioning zone," where during the six warmest months of
the year, the dry bulb temperature is 80 F or higher for over 650 hours,
or the wet bulb temperature is 67 F or higher for over 800 hours. (Per
OMB Circular A-45, Construction of Federally-funded Housing.) Deductions
for excessive cooling costs shall not be allowed unless the subject
quarter is located in an official air conditioning zone. Quarter is in
"air conditioning zone:" Yes No

3\. Enter on line 1 the average monthly cost of heating/cooling the
subject quarter. This is determined by dividing the total annual
heating/cooling cost by 12 (months.)

4\. Enter on line 2 the average monthly cost of heating/cooling
comparable but energy efficient housing plus 25 percent. This is
determined by the procedures set forth in 400 DM.

5\. Subtract line 2 from line 1. If a zero (0) or negative balance
results, no deduction can be allowed. If a positive balance results, the
amount on line 3 will be shown as the deduction on line 4.

**COMPUTATION OF DEDUCTION**

1\. Average Actual Monthly Heating/Cooling Cost of Subject Quarters:
\$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

(Attach documentation of prior 12 months of utility costs with meter
readings)

2\. Average Monthly Heating/Cooling Cost of Comparable but
energy-efficient quarters:

(Use a QMIS estimate or estimate manually from Survey Report and CPI
Memo)

Average Cost \$\_\_\_\_\_\_\_\_\_\_\_\_\_ + 25% of avg. cost
\$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ = \$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

3\. Average Monthly Excessive Heating/Cooling Cost (line 1 minus line 2)
\$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

4\. Average Monthly Heating/Cooling Deduction
\$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

(Enter "0" is line 3 is "0" or negative. If line 3 is positive, enter
line 3.)

**Certification:** The heating/cooling costs for the above quarter has
been compared with those of comparable housing, and adequate
documentation, including necessary receipts, has been provided by the
tenant. Based upon comparability and documentation, a deduction is is
not allowable as indicated in line 4 above.
