EXECUTIVE SUMMARY AET Consultants was retained by Halton Healthcare Services (Halton) to conduct an

energy assessment for Oakville Trafalgar Memorial located at 327 Reynolds Street,

Oakville, Ontario.

The original building was constructed in 1950; the facility has had numerous and

extensive renovations and additions over the years. The facility presently has a useable

floor area of approximately 38,599m2 and approximately 2,807m2 of glazing.

Primarily, the hospital is a multi floor structure, it is made up of different types of building

material; multiple layers of brick; concrete block/brick veneer construction and exposed

aggregate precast, the lower level is mostly below-grade with portions exposed for

access. The building envelope appears to be in excellent condition and is typical for this

period of construction. Cooling is provided via air handling units located in various

penthouses located on the hospital roof. Chilled water is supplied to these units from a

central chiller plant located in the powerhouse. Heat is provided to hot water systems via

high pressure steam supplied by steam boilers located in the powerhouse. Building

lighting is provided primarily by T12 fluorescent fixtures (75% of fluorescent lighting).

Sections of the hospital built and renovated in 1999 have been upgraded to T8 fixtures

(25% of fluorescent lighting). Incandescent fixtures have been refitted with energy

efficient compact fluorescent bulbs.

The energy intensity of the building for a twelve-month period (2009) was 3.49

gigajoules per square metre (GJ/m2). Table 1 shows normalized annual utility costs and

consumption for 2009. The building has higher than normal energy intensity.

Recommendations made here take into account the plan to close the hospital within the

relatively near future (~ 4 years), and are therefore limited to initiatives that would have

payback periods within that time frame.


Page 2

An immediate opportunity for energy conservation is to adjust the settings on generator

room ventilation fans to prevent them from running continuously when the outside

temperature is above the room setpoint.

The second opportunity for energy conservation is to replace the remaining T12

fluorescent lighting fixtures with more efficient T8 fixtures. The estimated cost of a

lighting retrofit is approximately $150,000. The simple payback for this upgrade is

estimated at 3.7 years.

We also recommend developing and implementing an energy conservation plan, and

energy management plan through consultation with a newly formed conservation team.

Much can be done with technology, but the best way to reduce energy consumption is

with conservation education and communication with the hospital staff as a strong part of

the conservation plan.

Finally, we recommend a review of current air handling unit filter replacement schedules,

and development and implementation of a filter changeout protocol to ensure all units

are serviced regularly.

1.0 INTRODUCTION AET Consultants was retained by Halton Healthcare Services to conduct an energy

assessment of the Oakville Trafalgar Memorial hospital located at 327 Reynolds Street,

Oakville, Ontario. This assessment is intended to support the establishment of a

baseline of energy and water consumption and to provide direction with respect to

options for improving the environmental and fiscal performance of the hospital in order to

support energy planning and target setting. The assessment will help better prepare for

emerging conservation and demand management requirements of the Green Energy Act

and potentially Bill 72, Water Opportunities and Water Conservation Act. On July 21,

2011, Frank Farkas, John Simonovich and Larry Jakabfy conducted on-site review

gathering vital information, to properly assess the buildings energy performance.

1.1 Facility Description This hospital is located at 327 Reynolds Street, Oakville, Ontario the original building

was constructed in 1950; the facility has had numerous and extensive renovations and

additions over the years. As a full service acute care community hospital, Oakville-

Trafalgar Memorial Hospital offers a full range of programs and services on both an

inpatient and outpatient basis. The major medical departments and Hospital services

include anaesthesia, clinical laboratories, diagnostic imaging, emergency, dialysis, family

medicine, geriatrics and rehabilitation, medicine, obstetrics and gynaecology,

ophthalmology, paediatrics, psychiatry and surgery.

Primarily, the hospital is a multi floor structure, it is made up of different types of building

material; multiple layers of brick; concrete block/brick veneer construction and exposed

aggregate precast, the lower level is mostly below-grade with portions exposed for

access. The hospital extends to a maximum height of five stories.

The roof is flat, inverted EPDM observed to have an average R-20 rigid insulation with a

remaining life expectancy of six years .

The building has a useable floor area of approximately 38,599m2 and approximately

2,807.65m2 of glazing. The hospital operates continuously.


Page 4

The climate is maintained at 72.5°F summer set point and 72.5°F winter set point, the

environmental control is accomplished through terminal units within the building, all units

utilize building recirculation air with a minimum fresh air set points of approximately

100%. Heating/Cooling changeover tempeture is set at 55°F.

Cooling is provided via air handling units located in various penthouses located on the

hospital roof. Chilled water is supplied to these units from a central chiller plant located

in the powerhouse. Cool air is supplied to terminal reheat units and heating is provided

via hot water coils supplied by hot water/glycol systems also located in the penthouses.

Heat is provided to the hot water systems via high pressure steam supplied by steam

boilers located in the powerhouse. The high pressure steam is also used for building

humidiifcation

Domestic hot water is provided via steam-heated tank-type water heaters. High

pressure steam is also supplied to the kitchen for food preparation and three autoclaves

in the CSR area.

Building lighting is provided primarily byT12 fluorescent fixtures. Only the sections of the

hospital built and renovated during the 1999 construction phase have upgraded T8

lighting. T8 fixtures current represents only 25% of all fluorescent lighting within the

facility. Incandescent fixtures have been refitted with energy efficient compact

fluorescent bulbs. The building envelope appears to be in excellent condition and is

typical for this period of construction.

Figure 1. Oakville Trafalgar Memorial Hospital 1.2 Scope of Work The scope of work for this study included the following:

• Review of utility billing including a summary report;

• On-site review of the hospital layout, usage, equipment review and identification;

lighting audit and HVAC system review;

• Generation of 3D CAD model of building;

• Data compilation, analysis and review;

• Generation of a RETScreen model; and,

• Generation of a report.

2.0 APPROACH AND METHODOLOGY The approach and methodology for the energy assessment addressed four phases.

These four phases are:

• Phase 1: On-site Investigation and Plan Review

• Phase 2: Data Collection

• Phase 3: Data Analysis

• Phase 4: Data Reporting

2.1 On-Site Investigation and Plan Review An initial site visit was scheduled with Gary Martin and staff from Oakville Trafalgar

Memorial hospital and involved the following:

• Performed on-site inspection of hospital, including:

Record of physical dimensions

Record of construction details

Generated an inventory of energy consuming equipment

Determined approximate service life of all large equipment

Generated inventory of dedicated equipment

Generated inventory of lighting fixtures

Completed any data which could not be obtained via the document review

• Developed, distributed and correlated Questionnaires as appropriate to gather

information from occupants/users of buildings, where necessary

• Conducted interviews with building operators, staff, occupants and/or users to

collect relevant data identified above

2.2 Data Collection The process for collecting all of the relevant data involved the following:

• Obtained existing data from Oakville Trafalgar Memorial, specifically:

24 months of utility billing data


Page 7

Building drawings, schedules and specifications (where available)

Building description, occupancy and operation details (where available)

Building energy performance data (where available)

Summary of future plans regarding building use and/or planned structural,

cosmetic modifications

Current energy related improvements or upgrades already planned or

implemented

Building operational records including equipment operation logs and

maintenance records

2.3 Data Analysis The next step in the energy assessment process was an analysis of the data collected to

determine energy consumption benchmarks, which can identify energy upgrade

opportunities.

Several tools were used to analyze the energy assessment data that involved:

• Formulating the data in tabular form, which will facilitate graphical interpretation

and analysis of the data.

• Standard spreadsheet software tools were used to determine energy

benchmarks in the building.

• Energy benchmarks were compared to national databases to identify the

buildings performance relative to other similar buildings.

• Building energy modeling software (including RETScreen and HOT2000) was

used to determine baseline energy usage.

• The modeling software was used to identify and analyse potential energy

upgrade opportunities, cost benefits and greenhouse gas reductions.

2.4 Data Reporting The results of the energy data analysis was used to develop a comprehensive energy

assessment report for Oakville Trafalgar Memorial. All raw data was recorded

electronically into a set of spreadsheets.


Page 8

The report includes all findings, recommendations, conservation measures and analyses

for implementing the identified energy measures. Tables and graphs showing the data

collected, benchmarks calculated, analysis performed and recommendations generated

is also included in the report.


Page 9

3.0 UTILITY ANALYSIS The main purpose of the utility audit was to analyze the building’s energy profile and

develop energy-efficient measures. To understand the patterns of energy consumption,

the electrical demand and consumption, profiles were analyzed as well as the gas

consumption profile for the building. Water consumption profiles have also been

reviewed to identify any opportunities for water usage reduction. The following graphs

(Figures 2 to 4) highlight trends in energy consumption (year over year) that help us

identify opportunities for energy conservation. It must be mentioned that a complete

twenty-four month set of utility invoices was not provided at the time of the energy

assessment. Data was provided in summary excel spreadsheets.

The energy intensity of the hospital for a twelve-month period (2009) was 3.49

gigajoules per square metre (GJ/m2). The average energy intensity for hospitals in

Canada is approximately 2.46 gigajoules per square metres (GJ/m2)1. Table 1 shows

normalized annual utility costs and consumption for 2009.

Table 1. Normalized Annual Utility Costs and Consumption 2009

Annual Utility Usage

Costs Consumption Intensity

Electrical $1,474,935 48,271 GJ 1.25 GJ/m2

Natural Gas $806,105 86,342 GJ 2.24 GJ/m2

Total $2,281,040 134,613 GJ 3.49 GJ/m2

3.1 Consumption Figures 2 to 4 illustrate monthly baseline of electricity, gas and water consumption for

the study period. Figures 5 and 6 illustrate the historical average heating and cooling

degree data for Oakville along with the actual data for the study years.

The electricity consumption profile for 2010 is similar to the consumption profile for 2009

(Refer to Figure 2). The increase in consumption observed in 2010 over 2009 during the 1 Natural Recourses Canada, Office of Energy Efficiency, Commercial and Institutional Building Energy Use Survey 2000, Summary Report.


Page 10

cooling months can be attributed to the increased cooling load for 2010 over 2009 as

indicated in the cooling degree data (Refer to Figure 6). The close correlation otherwise

is indicative of a mature building with little change in operational energy requirements. A

detailed breakdown of the facility’s overall electricity consumption can be found on the

Electricity Worksheet found in Appendix A. Electrical power demand data was not

provided for this facility so no analysis could be done regarding any excess charges

regarding electrical demand or power factor charges.

The gas consumption profiles for 2009 and 2010 also follow similar usage patterns

throughout the year (Refer to Figure 3). Upon review of the data, the January 2009 data

was not provided and the February and March 2009 data is suspect. These data points

do not follow the expected consumption profile as observed in the 2010 data and in

previous years’ data provided. We proceeded to generate a predictive equation to

calculate the expected monthly gas consumption as a function of monthly heating

degree days and the actual days within the month based on the data from April 2009 to

December 2010. This equation was then used to estimate the gas consumption for

January to March 2009. The predicted monthly gas consumption profile and the profile

used to develop the RETScreen model is also provided in Figure 3. There is a very close

correlation between heating degree days for Oakville, Ontario (Refer to Figure 5) and the

gas consumption for 2009 used for the model. The higher heating degrees per month

recorded for 2009 over 2010 translates to a corresponding increase of monthly gas

consumption observed on 2009 over 2010. A detailed breakdown of the facility’s overall

gas consumption can be found on the Gas Worksheet found in Appendix A.

The water consumption profile for 2010 is similar to the water consumption profile for

2009 (Refer to Figure 4). It appears that the peaks and valleys of consumption are out

of sync by one month. We were unable to determine whether this was actually the case

or whether monthly data was translated as only summary utility data was provided and

not actual utility bills.. A detailed breakdown of the facility’s overall water consumption

can be found on the Water Worksheet found in Appendix A. The water consumption of

this hospital is comparable to other hospitals of similar size and function.

3.2 Energy End Use The end use energy distribution was determined using RETScreen modeling software.

Interval metering was not used. The model uses historical and actual data to assist in

determining the energy end use and must be considered an approximation of energy

end use. Table 2 illustrates an end use estimation of energy consumption. A detailed

breakdown of end use energy consumption can be found on the RETScreen Energy

Model found in Appendix B.

3.3 Utility Billing Overview The utility billing reviewed was for a twenty-four month period from Jan, 2009 to Dec,

2010 provided by Oakville Trafalgar Memorial. The following graphs (Figures 7 to 12)

4.0 BUILDING AUTOMATION, MECHANICAL, AND ELECTRICAL SYSTEMS 4.1 Building Automation The building automation system is a Johnson Controls Metasys system installed in 1980.

The system is used for real-time monitoring and control of the HVAC systems. There

appears to be no provision for data logging, historical monitoring, tracking time of use

energy consumption, identifying downstream consumption of energy or water and no

way of identifying areas for load shedding or shifting.

4.2 Mechanical Systems The heating is provided by four (4) boilers:

• Four (4) 300 hp high pressure steam boilers operating at 110 psi steam

pressure. There are no economizers currently installed on the boiler stacks; and

the efficiency of these boilers is estimated at 78%. The steam boilers were

modified over the past two years to replace the mechanical linkage fuel/air

controls with direct digital operators to improve burner efficiencies.

• There is currently no heat recovery on the boiler blowdown system. Blowdown

is cooled via domestic cold water mixing and flushed to a drain.

The building steam is piped to individual mechanical penthouses located throughout the

facility. The steam heats glycol loops to provide heating to the coils located within the

terminal air handling units. Steam is also used to power steam/steam generators for

humidification control and is utilized in the hospital kitchen for steam jacketed kettles and

food steamers and for autoclaves in the CSR department.

Domestic hot water is provided by steam-heated tank type hot water heaters located in

the penthouses. Hot water setpoint is maintained at 140F at the penthouses to maintain

adequate hot water temperatures at the point of use. The facility has a solar preheat

system for domestic hot water. This system was installed in the 1970’s but was

decommissioned after damage due to mechanical failure. Approximately 50% of ot the

original system has been recommissioned and now uses a glycol-filled system to


Page 19

transfer heat to preheat the domestic hot water supply before it enters the storage tanks.

The domestic water supply is provided through two connections to the municipal water

supply and the pressure is maintained through booster pumps.

Air conditioning is provided by two centrifugal chillers; one at 1,000 hp and the other at

500 hp both with dedicated cooling towers. They provide chilled water to the individual

mechanical penthouses. The chilled water setpoint is at 42F. There were no variable

frequency drive’s observed on either of the chilled water pumps.

Conditioned air is provided by air handling units within the rooftop mechanical

penthouses. All units are typically running at 100% fresh air and the supply air setpoints

are 12-13C in the summer and 14-16C in the winter, return air is typically at 23-25C. Five

units have enthalpy wheel heat recovery systems and the remaining units have glycol

loop heat recovery. The average annual Coefficient of Performance (COP) cooling of

these machines is estimated to be 4.0.

The average air changes per hour (ACH) for the conditioned space within the building is

estimated at 5.8. The building is fitted with dedicated exhaust fans to provide both

general and local ventilation in addition to that provided by the air handling units. The

cumulative horsepower of all of the exhaust fans is estimated at 380hp based on

observation and drawings reviewed. 50hp of fans is estimated to be intermittent use (ie.

lab fume hoods, generator room fans), with the remaining fans running continuously.

4.3 Electrical Systems The building has two (2) separate high-voltage feeders supplying an internal two 27.6

KV transformer substation. There is also a 500 KW backup generator installed in the

building as well as a portable 800 KW portable diesel generator to provide sufficient

power to the facility in the event of a power outage. There is a 200 KVAR capacitor

bank installed to provide power factor correction. and maintain the system power factor

to greater than 0.90 to avoid extra utility charges. The system power factors observed

on the day of the on-site visit were 0.93. The generator room is ventilated with three 10


Page 20

hp fans. These fans are controlled by a maximum room setpoint, however; when the

outside air is above the setpoint the fans run continuously.

Major medical equipment modeled includes two (2) X-ray machines, one (1) MRI and

one (1) CT scan machine. The estimate of medical equipment electrical consumption is

shown below in the RETScreen model.

Figure 13. RETScreen Medical Electrical Equipment Usage 4.3.1 Lighting The lighting technology in the building is a mix of lighting technologies. The majority of

the lighting is fluorescent T12 fixtures. There has been some lighting retrofitting done to

upgrade some of the fluorescent lighting with T8 technology and replace incandescent

bulbs with more energy efficient CFL technology. This was done in areas of the hospital

built or renovated after 1999. There is very little use of occupancy controlled lighting. A

detailed breakdown of lighting can be found in the lighting data, Appendix C.


Page 21

5.0 DISCUSSION AND CONCLUSIONS Prior to conducting the on-site investigation, an energy audit pre-questionnaire was

distributed to Oakville Trafalgar Memorial. The staff was asked to answer a series of

questions relating to the hospital; facility overview, facility contacts, facility description,

general information, heating and cooling, lighting, kitchen/cafeteria, bathrooms, laundry

facilities, medical refrigeration, office equipment, medical equipment, water heating,

water and energy information, and site activities. Complete results of the questionnaire

can be found in the Survey Compilation, Appendix D. The results of the survey are only

a guide to better understand the performance of the building.

AET Consultants conducted an on-site investigation on July 21, 2011 gathering vital

information, such as: confirming the buildings dimension and construction details,

generating an inventory of energy consuming equipment, generating an inventory of

lighting fixtures and lamping, and dedicated equipment. The building’s exterior

dimensions and details were similar to the designed drawings. The large energy

consuming equipment is aging and at best, can be considered low to mid efficient. The

plug investigation revealed numerous pieces of equipment that either are on or are in

standby mode. These included but were not limited to: monitors, computers (CPU),

calculators and printers among other pieces of equipment. It is not known if these

pieces of equipment operate continuously. Based on these observations, it would appear

that Oakville Trafalgar Memorial lacks an energy conservation plan. It should be noted

that the hospital will probably only be in service for another 4 years as construction has

started on a replacement. Therefore upgrades will only focus on projects with payback

periods within this timeframe.

The building heating is provided by four (4) 300hp high pressure steam boilers. There

are no economizers on the boiler stacks and the efficiency of these boilers is estimated

at 78%. These boilers are capable of running on natural gas or light oil. High pressure

steam boilers are not a very efficient method of heating. The boilers were modified to

replace the mechanical linkage fuel/air controls with direct digital operators to improve

burner efficiency. Considering that space heating is the largest consumer of end use


Page 22

energy at 77,170 GJ, greater efficiency would help in reducing energy consumption and

assist in achieving a long term energy conservation plan, thereby reducing the overall

energy cost, however; considering that the hospital may be out of service in four years it

would not be cost effective to upgrade the boilers.

The generator room’s ventilation fans are controlled by a maximum room setpoint,

however; when the outside air is above the setpoint the fans run continuously consuming

energy that could be controlled.

It was noticed that some filters within local terminal units have not been changed on the

regular schedule. Failure to change filters on a regular basis can result in the units

operating inefficiently and could contribute to air contamination.

Building lighting is primarily T12 fluorescent fixtures. T8 fixtures current represents only

25% of all fluorescent lighting within the facility. There is opportunity to replace the

existing T12 fixtures.

6.0 RECOMMENDATIONS There is an opportunity for Oakville Trafalgar Memorial in the areas of energy

conservation and energy management and it is with this in mind that we recommended a

number of immediate steps be taken. These recommendations take into account the

plan to close the hospital within the relatively near future, and are therefore limited to

initiatives that would have payback periods within that time frame.

• Adjust settings on generator room ventilation fans to prevent them from running

continuously when the outside temperature is above the room setpoint. Making

these adjustments would result in an immediate payback by way of reduction in

electricity consumption.


Page 23

• Complete a lighting retrofit, replacing the existing T12 fluorescent fixtures with T8

electronic ballast fixtures throughout the facility. The cost of lighting retrofit is

estimated at $150,000. The simple payback for this upgrade would be 3.7 years.

• As-built drawing and schedules should be produced and kept up-to-date as

changes to the building and its equipment occurs allowing for better examination

of the buildings systems and tracking of building updates.

• Develop and implement an energy conservation plan, and energy management

plan through consultation with a newly formed conservation team. Much can be

done with technology, but the best way to reduce energy consumption is with

conservation education and communication with the hospital staff as a strong

part of the conservation plan.

• Review current air handling unit filter replacement schedules and develop and

implement a filter changeout protocol to ensure all units are serviced regularly.
