CORPORATION OF THE MUNICIPALITY OF CLARINGTON
40 TEMPERANCE STREET, BOWMANVILLE, ONTARIO L1C 3A6 T 905 - 623 -3379
REPORT NO.: CAO-006-12 PAGE 2
1.0 BACKGROUND
1.1 The Energy Management Steering Committee (Committee), as identified in
previous reports to Council continues to work on a number of initiatives with the
goal of reducing energy usage in our municipal facilities.
1.2 The Committee has undertaken a program to complete energy audits on
municipal buildings. To date audits have been completed on sixteen buildings
with the remaining buildings to be completed in the coming months. As identified
in the 2011 Activity Report to Council earlier this year, VIP Energy Inc. has taken
the findings of the first twelve audits and developed a master plan that identifies
all potential energy conservation measures. As the remaining audit reports are
completed, they will be integrated into the master plan.
2.0 ENERGY AUDIT MASTER PLAN
2.1 The Master Plan was developed by taking all of the energy conservation
measures identified and grouping them into categories. These measures include
water conservation; lighting retrofits; building envelope; boiler upgrades; and
other mechanical system upgrades.
2.2 The plan also provided cost estimated for each measure as well as an estimated
payback period. With a total cost of measures identified of approximately $1.6M,
the Committee decided to develop a short term plan to capitalize on the most
cost effective measures.
2.3 The Committee has undertaken a review of the full list of measures and has
identified those measures that have been calculated to have a payback of five
years and less. In addition, two lighting retrofit projects that have a payback of
less than six years have been included in the proposed list (Attachment 1).
3.0 GREEN ENERGY ACT
3.1 On January 1, 2012 Ontario Regulation #397-11, Energy Conservation and
Demand Management Plans, came into effect. The Regulation requires public
agencies to report on annual energy consumption and greenhouse gas
emissions as well as setting out targeted consumption reductions and the
measures that will contribute to realizing energy reductions.
3.2 The Municipality will be required to prepare this report on or before July 1, 2014.
The completion of this master plan and the approval to implement a number of
the conservation measures will assist the municipality to fulfill this reporting
requirement.
REPORT NO.: CAO-006-12 PAGE 3
4.0 FINANCIAL CONSIDERATIONS
4.1 The total cost of the conservation measures being proposed is $479,576.00
(Attachment 1)
4.2 It is proposed that the cost of the conservation measures be financed from the
Municipal Government Enterprise Reserve Fund.
4.3 Included in the Master Plan are the estimated savings calculated by VIP Energy
for each measure. Upon completion of the measures any realized savings
directly attributed to the measure, will be directed back to the Municipal
Government Enterprise Reserve Fund to repay the financing provided. This will
allow for a replenishment of the funds from utility savings that could be used for
future conservation measures not included in this initial phase of the program.
5.0 COMMENTS
5.1 This implementation strategy aligns with the Corporate Strategic Plan 2011 –
2014. One of the priorities of the plan is to "Promote Green Initiatives" with the
objective to reduce the Municipality's energy consumption. It is recommended
that a corporate-wide approach to this program will best serve the Municipality in
meeting this objective.
5.2 By investing in energy conservation measures, the Municipality will reduce
consumption; control costs associated with energy; and reduce greenhouse gas
emissions.
5.3 In addition to the Energy Master Plan Program, the Committee is working on a
number of other initiatives and will continue to report to Council. The Committee
will also continue to work with our local energy distribution partners to find
programs that are beneficial to the Municipality to reduce energy use and energy
costs.
CONFORMITY WITH STRATEGIC PLAN –
The recommendations contained in this report conform to the general intent of the
following priorities of the Strategic Plan:
_ Promoting economic development
Maintaining financial stability
_ Connecting Clarington
X Promoting green initiatives
_ Investing in infrastructure
_ Showcasing our community
— Not in conformity with Strategic Plan

Many of the shower heads installed in the change rooms are old and rated for a flow rate of between 4,5-5.5 gpm,with the majority of the shower heads being in the 5,0 gpm range.While they do have a timed tap set they are still using far more water than they need to.The
savings come not only from the reduced water usage but also from the reduced gas usage for generating hot water due to the installation of the low flow shower heads.Users can be very sensitive to shower head changes so it is recommended you try several different
types with the staff first to gauge user acceptance before retrofitting all of them.Purchase the estimated number of low Energy Loss flow shower heads indicated in this audit and install them systematically throughout the building.

Humidity control is critical with an indoor pool facility.Recently,an exhaust fan was replaced with a new Soler&Palau(S&P)fan.There was a humidistat installed for the original fan and currently this has just been left on so the fan operates constantly.While this may
control humidity it is also not the most efficient approach.Using this existing control will reduce the operating time of the fan and water loss through evaporation.ASHRAE 62(1995)recommends a relative humidity setting of 60%while the NAVMED P-5010-4 suggests 70%
is acceptable.

The air circulation requirements of the building are met primarily by rooftop air handling units.Programmable thermostats control the operation of the AHUs by determining the demand.The thermostats,however,do not appearto have night time setbacks fully programmed.
As the building is unoccupied at night,the temperature can be set back to 160C in the winter and 250C in the summer.Savings have been calculated for a 20C setback.A good rule of thumb generally used states that for every 10C setback over an 8 hour period,3%can be
saved on heating,and 5%can be saved for cooling.For 20C,a conservative 4%has been estimated for heating and 5%for cooling.It is recommended that setbacks are commenced on a trial basis until the ideal setback temperature is found for this building.

The heat pumps that service the office area are controlled by manual thermostats.These thermostats are not turned down at the end of the day when the occupants leave the building.Install programmable thermostats to control these units.Programmable thermostats offer
setbacks that ensure that the units are setback when the space is unoccupied.A general thumb rule is that for every 1 degree setback over an 8 hour period,savings of 3%for heating and 5%for cooling can be estimated.The savings have been calculated here assuming a
3 degree C setback.

Nearly all the fans in this facility are driven by Flat V-belts drives.The only cogged belt noticed was in the HVAC cooling tower.Flat belts tend to have higher transmission losses caused by slip between the belt and pulleys.Cogged V-belts on the other hand reduce slip and
improve the transmission efficiency.This results in lower power consumption.Upgrade the V-belt drives systematically during the preventive maintenance shut downs.This calculation has been done for fans rated for 3 HP and above.but the belt upgrades should ideally be
extended to all fans driven by a belt drive.Savings of 2%can be estimated.

The domestic hot water loop in this building,like all others,runs 24 hours per day.The original idea behind this was that someone,somewhere in the building could need hot water at any time,and certain temperatures must be met in order to avoid bacterial issues.Savings
are realized with this building only operating during business hours.Installation of a timer will mean users may have to wait a little longer for hot water during the off hours but standby and pump losses will be significantly reduced.This energy measure looks at putting a
timer on the DHW circulation pump so it only runs during normal operating hours.

Currently,the old hose tower leads up from the lower bay area into a chimney above the roof line.This results in a"natural draft"due to the difference in the density of the conditioned inside air and the outside air,significantly increasing the amount of conditioned air
required.This chase needs to be fully sealed off and insulated in order that the natural draft is eliminated.

The integrity of the building envelope is in very poor condition for most part,many door and windows doors have damaged seals and are missing door sweeps.Such cracks result in infiltration of the ambient air into the conditioned space of the building leading to unwanted
heat loss or thermal gain.Repair all damaged door seals and consider installing door sweeps or repairing weather stripping at the bottom of the doors to reduce energy loss through these openings.The seals around the garage doors require to be replaced completely.The
energy loss has been calculated using standard tables from NRCan's Energy Management Series,Section 18,Table 3.Weather conditions have been considered using data from the Oshawa weather station:Annual HDD=2,979 days and Annual CDD=225 days.
Average thermal efficiency considered is 70%.Please note that the savings shown is for a crack of 0.75 in in length.A crack is defined by NRCan as an opening of less than 10 mm in width.

Currently,in the lower bay area,the original fire engine door is still in place with nominal insulation value and a significant infiltration level due to limited air sealing measures around this door.Tbis EMS requires the removal of this door and the installation of a fixed panel
with at least four inches of isocyranurate insulation.along with two fixed double glazed,Low E,windows for daylight.Savings were estimated by modeling the current building envelope and then modeling it with the bay door replaced with an insulated panel which is fully
sealed into the building envelope.Energy savings were then the difference between these two heat loss scenarios.

Currently,the pool is lit with 14 wall mounted fixtures which have twin 400 watt metal halide lamps in them.These are not very efficient and with the long restrike time it also makes it very difficult to shut any of the fixtures off during unoccupied hours.We recommend
retrofitting all of these fixtures to vapor fight High Output(HO)T5 fixtures.These will provide better quality light more efficiently with an"instant on"capability and will easily allow the facility to shut offfixtures when the pool is not occupied.Ideally,the fixtures should also be
rewired so that a minimum number offixtures can be left on during unoccupied hours for safety and then all the fixtures turned on when required.

Most of this facility uses the older inefficient T12 lamps which were no longer commercially available effective July 1st,2010.Although replacements can still be sourced they are getting harder to locate and should be replaced with T8 lamps which are much more efficient.
There are also several incandescent lamps present which are also very inefficient and will be phased out by 2014.The following is a simplified look at how the lights should be replaced,understanding that a detailed lighting audit may reveal even further improvements
allowing further de-lamping or lamp removal,daylight harvesting and motion sensing.

Most of the lighting installed in the building is energy efficient.Area lighting consists of mainly 32 W T8s.The parking lot lighting is also addressed to be replaced with LED lighting.This technology is finally reaching a level of maturity sufficient for widespread application.
The pricing,stability and availability are now sustainable for the average purchaser.The following is a simplified look at how the lights should be replaced,understanding that a detailed lighting audit may reveal even further improvements allowing further de-lamping or lamp

The common washrooms in this building,like most public washrooms,see highly variable occupancy.Occupancy is higher during the day and tapers off during the evening.However,all the lights remain on continuously.Install dual infrared—ultrasonic motion sensors to
turn off the lights when the washrooms are not occupied.Often there is a concern that lights may turn off while people are still inside the washroom as at times there may be no movement across the line of sight of the sensor.Ultrasonic motion sensors address these issues
as ultrasonic beams can bend around corners to detect the slightest movement.These motion sensors are recommended to be installed in the ground floor mens and womens washrooms.Each washroom has two T8 four lamp fixtures and twelve single lamp T8 fixtures.
Assuming 12 hours operation per day,the annual power consumption=(2 x 2 x 0.128+2 x 12 x 0.032)x 12 x 30 x 12=5,530 kWh It is estimated that the actual occupancy of the washroom will require the lights to be on for only a total of 6 hours per day.The electricity
savings=5,53012=2,765 kWh

Most of the lighting installed in the arena is energy efficient.Area lighting consists of mainly 32 W T8s.The ice rinks are illuminated by 40OW metal halides.These lights use more energy than high bay T5 lights or LED lights.Further,metal halides have a warm up time and
do not start up immediate.This forces operators to leave the lights switched on even when the rink is not being used.Upgrades to LED or high bay T5 lighting will reduce the electric demand and will also reduce the number of hours of operation of the lights.The parking lot
lighting is also addressed to be replaced with LED Lighting.This technology is finally reaching a level of maturity sufficient for widespread application as prices,stability and availability are now sustainable for the average purchaser.
