Appl~catlon/Proqram Summary
The City of Denton Utility Department is offering cash
payments to customers who purchase and install high
efficiency air conditioners or heat pumps for new
residential, existing residential or commercial
facilities This program, called "EnergySave", will
provide structure incentives to residential builders for
meeting specific City of Denton structure requirements
Satisfying these construction requirements will improve
a residential structure's operating efficiency
Apartments and multiple unit residential structures will
qualify if they meet the EnergySave Program Guidelines
The EnergySave Program's ob]ectlves are to reduce energy
demand and consumption, thereby saving Denton Municipal
Electric Utility (DMUE) customer's dollars on their
utility bills, reducing the peak load of the City of
Denton's electric system and promote energy efficient
heating

II CENTRAL ELECTRIC AIR CONDITIONERS kND HEAT PUMPS
A A new condensing unit with an inside evaporator
coil will qualify if matched, as specified,
the current issue of the ARI Directory of
Certified Air Conditioners and Air Source Heat
Pumps and the unit meets the minimum ratings as
specified an the 1998 EnergySave Program If
the unit as not an the current ARI Directory,
the manufacturer's latest data approved for
publication wall be accepted
If the unit is not an the current ARI Darectory
or data approved for publacatlon, the average of
the high and low SEER/EER coil only, not
ancludang blower coil, will be accepted as
listed in the current ARI Darectory
B Computer simulations may be used if ratangs are
not lasted an the current ARI Directory,
provided the following criteria are met
1 Systems usang mix-matched coals must meet
all established program gu~delanes to
qualafy for a rebate
2 The computer samulatlons must be sagned,
certified, and dated by a registered
professional engineer and an officer of
the company making the submittal
3 The engineer who certafles a samulataon
must
attest to the accuracy of the input data,
the valadlty of the calculation procedure
used, and that the results are ~n accor-
dance with Department of Energy approved
methodology
5
4 A complete set of the input data and an
ln-dlcatlon of the source of the data must
accompany the simulated ratings
5 The slmulated ratings must be based on the
condensing unit's tested combination as
listed ~n the current ARI Dlrectory or
latest data approved for publication and
ldentlf~ed by the correct model numbers of
both the condensing unit and co~l as
listed
· n the current ARI D~rectory
6 SImulated ratings must not exceed 105% of
the SEER rating of the tested system used
as a base
7 An open f~le of computer sImulations will
be maintained at the Energy Management
Office Supplying erroneous ratings or
data can lead to d~squal~f~catlon of those
involved from further program
partlclpatlon
C Program Capacity and Payment Formula
1 The maximum allowable BTU per hour
capaclty eligible for a residential rebate
is determined by dividing the square
footage of the a~r-cond~tloned area by 600
and multiplying by 12,000
Example The Program Capacity for an 1,800 square
foot house is
1.800
= 3 0 x 12,000 = 36,000 BTUH
600
The City will pay a rebate on a unit that
meets program efficiency standards and is
s~zed at 36,000 BTUH or less
2 Actual payment w~ll be determined by
dzvldlng the BTUH of the installed unmt
(up to, and lncludmng the Program
Capaczty) by 12,000 and multiplying by the
incentive
6
The incentive amounts and SEER ratings are
referenced of the ~1998 EnergySave Program
Methods Used in Determining Equipment
Efficiency and Eligibility," and are
incorporated herein as if fully set forth at
length
Example A A person in a 2,100 square foot house
installs a 42,000 BTUH central air conditioner with an
SEER rating of 12 0
2,100= 3 5 x 12,000 = 42,000 Program Capacity
600
42,000 = 3 5 x $100/ton = $350 00 Incentive
12,000
Example B A person in a 2,400 square foot house
installs a 60,000 BTUH central air conditioner with a
SEER rating of 12 0
2,400 = 4 x 12,000 = 48,000 Program Capacity
600
48,000 = 4 x $100/ton = $400 Incentive
12,000
Example C A person in a 2,400 square foot house
installs a 60,000 BTUH central heat pump with a SEER
rating of 12 0
2,400 = 4 × 12,000 = 48,000 Program Capacity
600
48,000 = 4 × $150/ton = $600 Incentive
