Attached is a comparative cost analysis from the City's Public Building
Department showing the Electrical Heating System verses the Gas Heating
System for the Center. An annual energy cost savings of $2,779.00 is
indicated for the first year of operation.
Other items of work to be done can not show direct savings, however, an
indirect savings will be attained through maintenance efficiency.
We recommend that Change Order No. One be approved.
Attachment.
URGENCY CLAUSE:
In order to maintain time lines and allow
contractor to complete gas/electrical lines
in timely fashion, Change Order must be approved.
Failure to consider Change Order would delay
entire project until such time as matter is
approved.

Wayne Overstreet
SUBJECT: COST ANALYSIS NICHOLSON RECREATION CENTER
ELECTRICAL VS. GAS SYSTEMS

COPIES:
Energy Auditor, Building Maintenance Supervisor,
Heating and Air Conditioning Foreman
-------------------------------------------------------------
A comparative cost analysis of change order for the heating
and air condition, water and cooking range, from all electric
to a gas system.
The major concern of this division is the cost of maintenance
difference between the two systems, manhours, materials and
energy) .
Our analysis will address each, utilizing two types of
existing facilities in the city inventory that have similar
functions and operating hours, with a combination of gas and
electric system, and another facility were we have all
electric, and an analysis of proposed cost of the two systems
as proposed by the contractor.
Analysis are as follows (all city facilities)
All electrical system (cost per square foot per year)
(a) Utilities.................................$1.82.0
lb) Maintenance & Materials...................$0.9l.l
TotaL.. $2.73.1
Combination of Electrical & Gas (cost per square foot per
year)
(a) Utilities.................................$1.33.0
(b) Maintenance & Materials...................$0.84.8
TotaL.. $2.17.8

Analysis - Nicholson Recreation Center
1. All electrical system (cost per square foot per year)
(a) Utilities = 5024 sq. ft. X $1.82 =.......$9,144
(b) Maintenance & Material 5024 sq. ft. X
$0.91.1 =................................$4,577
Total......$13,72l
2. Combination of electrical & gas (cost per sq. ft.
per year)
(a) Utilities 5024 sq. ft. X $1.33 =........$6,682
3.
(b) Maintenance & Material 5024 sq. ft. X
$0.84.8 =...............................$4,260
Total......$10,942
Annual cost difference (first years).......$ 2,779
Based upon our experience with the maintenance of
heat pumps in other city HVAC systems, and electrical
hot water, and cooking ranges as those specified for
Nicholson Recreation Center, an annual cost saving in
maintenance can be anticipated if changed to electric
and gas system, of approximately $1,300 after the
first year of operation.
A comparison
equipment vs.
$22.34 as per
was also made on the cost of the original
the proposed units. The cost difference was
quote from Desert Service Company.
Based upon our cost analysis, utilizing only our first year
savings as a base point, this change order would pay it self
back in less than 2.08 years, therefore it is our conclusion
that this chan e or r is cost effective and should be
ap roved.
