1) Smartcool USA Inc. Proposal
Recommendation:
By Minute Motion:
1) Approve Contract No.c21080 with Smartcool Systems USA Inc. in the
amount of $39,932.00 for the installation of proprietary Energy Savings
Modules on the 8 HVAC units at the Desert Willow Clubhouse.
2) Approve a 10% contingency in this contract in the amount of $3,993.00.
3) Authorize the Director of Finance to appropriate $43,925.00 for this
contract from account 241-4195-495-8092. Funds are available in this
account. No additional appropriation is needed.
Executive Summary:
The approval of this contract and the installation of these Energy Savings
Modules at the Desert Willow Clubhouse will result in a guaranteed energy
savings of over $12,600.00 per year. With these savings, the Smartcool
system will pay for itself in approximately 3 years.
Discussion:
Staff has been looking at ways to save energy and thus, money at the
Desert Willow Clubhouse. A site survey was done by Smartcool USA,
which revealed that the HVAC systems at the clubhouse are an ideal
candidate for this new technology.
How it works: The Energy Savings Module (ESM) is a system of micro-
computer digital optimization modules specifically designed to reduce the
run time of refrigeration and air conditioning compressors by 15% to 40%
and therefore reducing electricity consumption by 15% to 20%, while
maintaining consistent temperature performance. The ESM is designed to
interface with the HVAC controls at Desert Willow, and complements rather
than replaces the existing controllers for air conditioning and refrigeration

compressors. The ESM utilizes worldwide exclusively copyrighted software
that has been developed over 20 years to augment existing building and
refrigeration control systems.
Guarantee: The proposal outlines the guarantee Smartcool USA provides
on this system. Simply put, Smartcool USA guarantees an energy savings
of $12,679.00 per year and a payback of 35.07 months. If the Smartcool
system does not perform to these expectations, the City will get either a full
refund, or the price of the system will be reduced to provide a return on
investment of not to exceed 35.07 months.
If this system performs to the manufacturer's expectations, staff will look
into using this system on the Civic Center HVAC systems.

Electricity Reduction Proposal for
Desert Willow Golf Resort — Club House
Control of Air Conditioning Units
Thank you for providing Smartcool Systems USA Inc. ("Smartcool") the opportunity to submit
this proposal to reduce the electricity consumption, and KW demand related to the 11 air
conditioning compressor units at your facility.
This proposal is based on data from nameplates, Southern California Edison (SCE) utility
bills for your facility over the last 12 months and the assumption that the Trane air
conditioning compressors are turned on for 24 hrs per day 7 days per week, as seasonally
adjusted.
The complete saving and environmental calculations are attached. Briefly the savings
calculations for your system show:
Annual kWh Reduction 91,468 kWh
Annual Dollar Savings $12,679
Once only Cost $37,059*
Annual ROI 34.2%*"
Months Return 35.07 Months**
Five Year Savings $63,394
` Does not Include sales tax "Pre-tax and does not include savings from increased compressor life.
The purchase price includes installation costs, together with commissioning and set up, plus
a one year warranty including all parts and labor. There are no extra charges. The quoted
price will remain valid for a period of 30 days from the date of this proposal.
Air Conditioning Details
The basis of this proposal is to install Smartcool Energy Saving Modules (ESM)T"" to control
11 Trane compressor units, located on the roof, servicing the locker rooms
(YCH121C4LOAA), conference room (YCH181C4LOAA), snack bar (YCH103C4LOAB), pro
shop (YCD211 C4LOAB), reception (YCD091 D4LOBE 8� YCD061 C4LOBF), kitchen
(YCD121C4LOAA), bar (YCD151C4LOAA) and three miscellaneous rooms (YCH121C4LOAA,
YCH211C4LOA6 8� YCD061C4LOBF). The ESMT"" is designed to maximize the efficiency of
the compressors by utilizing Smartcool's unique, independently verified and copyrighted
software driven compressor optimization controls.

Environmental Benefits
In addition to the substantial monetary savings estimated, the installation of the Energy
Saving Module SystemT"" will also provide significant environmental benefits for the whole
community. Each year the initiatives detailed in this proposal will save enough
electricity to supply approximately 9 homes and reduce annual Greenhouse gas
emission by 123,379 Ibs. The Greenhouse Gas Reduction from the ESM installation
is equivalent to planting approximately 67 acres of trees and eliminating 13
passenger cars from the roads.
Equipment to be installed:
Units
Network Controllers(LNC3) 8
System Interface Modules(SIM2) 6
System Interface Modules(SIM8) 2
PT 100 Sensors 8
Transformers 8
Guarantee: Measurement � Verification
The energy reduction performance of the Smartcool products instalfed may be evaluated
within three months after completion and commissioning of the installation. The evaluation
will be carried out in accordance with Smartcool's standard Evaluation Procedure outlined
below.
Smartcool will install a remote alarm in the manager's office in the event an ESM fails,
which may entail a cost to the City of Palm Desert, and communications software will be
installed on the manager's computer in order to keep track of run hour savings.
The evaluation will also form the basis of an application to Southern California Edison
(SCE) to access the rebate program available for the installation of the equipment. The
funds received will also form part of the payback calculation, which is estimated to be
$7,317 which is based on $.08 cents per kWh saved in the first year. The City of Palm
Desert acknowledges that the total funds received will go directly to Smartcool. This will
reduce the pay back period to 35.07 Months and total a once only cost of$37,059.
In the event that the measured kWh reduction is less than stated in this proposal or there is
an amended proposal replacing this proposal by a value greater than 10% of the stated
quantity then Smartcool agrees to adjust the purchase price of the installation to provide the
client with a return on investment not exceeding 35.07 months. Alternatively at Smartcool's
sole discretion, Smartcool may remove the installation and refund any money paid for that
installation.

Evaluation Procedure
The following is !he stundard procedure adopted by Smartcool to determine Ihe energy
reduction performance and temperature maintenance of the Energy Saving Module when
installed on air conditioning und refri�eration equipment.
1. Methodology: An Energy Logger will be installed on the electrical service to the air
conditioning or refrigeration compressor. The Logger will record the amperes, KW, KVA,
& Kwh. In addition a temperature data logger will be installed to monitor the ambient
temperature and the temperature of the controlled medium, either chilled water, return air
temperatures or conditioned space temperatures.
The air conditioning and refrigeration plant will be operated alternate weeks with the Energy
Saving ModuleT"" switched on and off to achieve a seven day comparison. The duration
of the trial is normally for two weeks.
The loggers are set to provide a print out every hour and summated every 24 hours. This
provides a "weekday" comparison, for example compare Monday week 1 to Monday
week 2.
The data from the logger is downloaded on site at the conclusion of the evaluation.
2. The Loggers: The Energy Logger will either be an ACR Model SR003, a Power Site
PS250 Meter or a Pacific Technologies E Logger or equivalent. The logger is non-
intrusive, does not require any interruption to the supply or the disconnection of any
power cables. The loggers utilize clamp on current transformers and voltage probes to
collect the relevant data.
3. The Report: At the conclusion of the evaluation period a report will be presented to the
client. The report will provide details of any financial and environmental benefits and
outline the cost effectiveness of the installation of the Energy Saving Modules.
The report will include a copy of the numeric data collected from the loggers.
All log�ers have a sampling rate of 8 seconds and c•un be pro��-ammed to summute and print the data
for any time interval. The loggers are fully apprnved tn Australian Standards, USA Underwriters
Laborutories (UL) CSA and C.E. reyuirements.
