1 SCOPE

This document represents an evaluation of the existing mechanical (HVAC) and electrical systems serving the building and an assessment of their condition, life expectancy and suitability for the current use of the space. The evaluation is based on our site investigation, interview with the caretaking staff and a review of the available documentation in the TCDSB archives. The evaluation was strictly visual; no tests or measurements were taken and no building services embedded in walls, slabs or located underground were examined. This document also includes proposed design recommendations to improve the heating, ventilation and air conditioning in the school portion of the building as well as the electrical distribution and lighting. 2 GENERAL The building was constructed around the 1920's and the facility is currently shared by the School Board and the Abbey. The building is a 3 storey building on the school side and a 4 storey building on the Abbey side. The school occupies approximately 9,700 sq. m floor area on three floors and the Abbey occupies approximate 8,000 sq. m floor area on four floors (basement on the Abbey side is partially not excavated). There is not a clear delimitation between the usage of the space, the majority of the service spaces are common for both users and the lunch room is located on the Abbey side below the chapel. Some of the staff offices are now located at the third floor on the Abbey side in old bedrooms. 3 EXECUTIVE SUMMARY

The heat for the existing building is provided by a steam plant and distribution piping and equipment. The steam system is:

• Energy inefficient • Exceeded its life expectancy • Has no zone control capabilities

The school ventilation system is an exhaust type only, consisting of 4 general exhaust fans with no provisions for make-up air. The science rooms are provided with a separate ventilation system consisting of make-up air, general exhaust and fume hood exhaust. The ventilation system for the Abbey portion of the building consists of a general supply and exhaust fan that supply and extract air from each room. With the exception of the library, the building has no provisions for air conditioning. The existing power supply is relatively new and appears to be adequate for the current load. Some of the distribution panels, local disconnects and wiring are old and overloaded. The lighting system is a combination of T12, T8 and HID lamp fixtures. The emergency lighting does not provide adequate coverage in certain areas.

5 EXISTING HEATING SYSTEM

5.1 Heating System

5.1.1 Overview The existing heating for both the school and the Abbey, is provided by a steam plant. This type of heating system is inefficient with a lot of waste in terms of water, chemicals and energy. The system is very difficult to control and the type of controls available are inaccurate and a set point cannot be maintained without a wide dead band. System suffers from significant lag times between the boiler turning on and the heat arriving in the radiators. As a result, the system makes it difficult to implement accurate control strategies such as a night setback system. There is no or limited zoning and there is no individual heat control in each space. The building has the problem of uneven heating, which is a big cause of energy waste and complains from staff. The existing steam plant requires constant supervision by a stationary engineer and the maintenance cost is higher compared to a hot water boiler system

5.1.2 Equipment and distribution

The steam plant consists of two boilers, condensate vacuum pump (Dunham-Bush - 20 psig, 25,000 capacity), condensate tank, condensate circulation pumps and local controls. The boilers are manufactured by Boiler Smith and have a capacity of 1,671 kW (5,646 MBTUH) maximum input (each). The boiler plant was last upgraded/ replaced in 1996. The control of the steam plant is done locally by manual timers and pressure controllers (steamtrolls) that control the steam valve operation for day/ night.. The existing boilers are 18 years old, and are close to the end of their life expectancy. Some of the boiler plant components are older (condensate tank) or newer (the vacuum pump). The distribution pipes and condensate traps are old (original to the building) and have started to show signs of corrosion and leaks. The chemical treatment equipment is old and in poor condition. There is no softener for the make-up water which adds to the degradation of the pipes and equipment. The steam system is a 2 pipe system with the main low pressure steam distribution pipes located in the attic of each building. There are three main risers from the basement up to the attic. Only one of the risers (serving the Abbey) has an additional control valve controlled by a thermostat located on the fourth floor. Vertical steam and condensate risers distribute steam and collect condensate from each space. The heating is locally supplied to each room through cast iron radiators. With the exception of several classrooms, the radiators are old and appear to be original to the building. In classrooms122, 121, 111 and 118 the radiators have been replaced with a new style steam radiator. There is no local control of the heat output in any of the spaces. The main condensate loop is located in the ceiling of the basement with a secondary loop that serves the basement radiators located at floor level. A portion of this loop is partially located underground to avoid tripping hazards at corridor crossing and doors. The Chapel heating system is a hot water in-floor heating system. The hot water is produced in a heat exchanger using steam as primary heating agent. The heat exchanger, the two lead/lag in line circulators, condensate vacuum pump and controls are located in the basement in a small mechanical room. The system is in good condition. 6 VENTILATION SYSTEM

6.1 General School Ventilation The school portion of the building is provided with a general exhaust system that extracts about 288 L/s (400 cfm) from each classroom. There are 4 general exhaust fans collecting through 10 exhaust risers. The exhaust fans are roof mounted centrifugal type fans. All main horizontal ductwork distribution is located in the attic of the school with no access for maintenance. The exhaust fans are in average condition (installed in 1972) and were working at the time of our visit. Based on information from existing drawings the general exhaust fans are:

• EF-1: 2,150 cfm


L4C 9Y6 Tel: (905)-787-8885


Page 5 of 20


• EF-2: 3,350 cfm • EF-3: 3,100 cfm • EF-4: 3,600 cfm

Two additional exhaust fans located on the school roof serve the girls and boys washrooms. The fans are relatively new (installed in 2007) and are controlled by timers installed in the attic (accessible from 4th floor of the Abbey). Both fans are manufactured by Carnes and are equipped with fractional HP motors. 6.2 Science Lab 312 Ventilation

The ventilation system for Science Lab 312 was modified in 1987. A vertical fan coil unit with an electric heating coil provides the required ventilation air through a louver in the outside wall. The fan coil is interlocked with a wall mounted propeller fan. The unit was not "ON" at the time of our visit. The system is controlled by local switch. The system is about 27 years old and exceeded its life expectancy.

6.3 Science Lab 309 and Prep. Room 310 Ventilation The ventilation system for these rooms was renovated in 2003. The system consists of a roof mounted gas fired make up air unit manufactured by EnMar and associated room exhaust fan, hood exhaust and chemical cabinets exhaust fans (located on the roof). The existing equipment performance is as follows:

• MAU-1: 750/375 L/s ; 58.6 kW (200 MBH) • EF-05: fume hood exhaust: 380 L/s; 0.167 kW • EF-06: general exhaust: 380 L/s; 0.187 kW • Ef-07: cabinet exhaust: 85 L/s; 0.248 kW

The new exhaust fans are in good condition. The make-up air unit is not operational, the belt is broken and the filters are completely clogged. 6.4 Pool and Change rooms Ventilation The ventilation system for the pool area consists of two wall mounted propeller fans. There is no make-up air provisions for this space. The fans were operational at the time of our visits. The change room ventilation consists of one window mounted propeller fan. The operation of these fans is controlled by local switches/ timers. The equipment is in poor condition and very noisy. 6.5 Electrical room Ventilation A new ventilation system was installed 1996. The system consists of one inline exhaust fan interlocked with an outdoor air motorized damper. The fan and the outdoor damper are located in storage room 102A. The air is supplied and exhausted to/from the electrical room through wall mounted grilles.


L4C 9Y6 Tel: (905)-787-8885


Page 6 of 20


The fan is not operational. 6.6 Elevator Machine Room and Mechanical Room Ventilation The elevator machine room and the small mechanical room located in the basement (heat exchanger room) are provided with a common supply system and individual exhaust fans. The inline supply fan provides the air from the outside (through a wall mounted louver) or from the basement corridor. A series of motorized dampers located in the ductwork system modulate the amount of outside air and indoor air in order to maintain a pre-set supply air temperature. The exhaust fan for each room are wall mounted propeller fan interlocked with the supply fan and are controlled by room thermostat. The air is exhausted to the corridor. The equipment is more than 20 years old and in average condition. 6.7 Abbey Ventilation We have conducted a review of the ventilation system serving the Abbey for information purposes only. No remedial action are covered under this report. With the exception of the basement area, the rest of the three storey were initially designed as dormitories. Ventilation air is provided to each room from a supply fan located in the attic space. A glycol pre-heat coil and a steam heating coil maintain the required supply air temperature. The heat exchanger, circulators and glycol station are located in the attic. The air is exhausted through the dormitories' washrooms by a an exhaust fan located in the attic. According to the custodial staff, the supply fan heating coils are cracked and not operational. The entire system, supply fan, exhaust fan, coils and pumps are old and beyond their life expectancy. A separate fan coil unit with DX coil provides cooling for the archive area. The unit is located in the attic with the condenser located on the school roof. A separate cooling and humidification unit is provided for the documents storage area inside the archive. The system consists of 1 ton fan coil unit c/w DX cooling, roof mounted condenser and electric Nortec humidifier. The fan coil unit and humidifier are located in a small mechanical closet at the fourth floor. Both fan coil units are in average condition; the condenser for the archive unit is in good condition, but the condenser for the documents storage cooling unit is in very poor condition. 6.8 Miscellaneous Equipment During our site review we have noted a series of small window type AC units and small wall exhausters installed in some of the classrooms.

7 PROPOSED UPGRADES of HVAC SYSTEM 7.1 Heating System Steam systems have an average service life of approximately 25-30 years. While the boilers are only 18 years old, the rest of the system including pipes, traps, radiators are more than 70 years old. The overall system exceeded its life expectancy. The existing system is energy inefficient and has no capabilities of controlling the temperature in each space. In order to upgrading the heating system, improve its efficiency and enhance its controllability we propose the following options: 7.1.1 Option 1 Maintain the steam heating system and perform only replacement of major elements and controls. This will include:

• Replace the boilers with new steam boilers with higher efficiency and new DDC controls. • Replace the condensate pumps, vacuum system and all exposed piping in the boiler room that

are rusted. • Provide new chemical treatment. • Install thermostatic control valves at each radiator to control the steam capacity and maintain

the room temperature. • Pressure test the existing piping system to determine any leaks. Replace portion of pipes as

required. • Replace all existing valves and steam traps. Add new control valves for the three zones up in

the attic to improve the overall control of the system. • Replace existing radiators that are rusted. A three year program is recommended to replace all

the radiators. The upgraded system will be more efficient than the existing one with better controls, improved comfort for staff and students. However the majority of the distribution pipes will remain. 7.1.2 Option 2 Establish a three year program to convert the steam heating system to a hot water system. Conversion from steam to how water requires replacement of the boiler, distribution piping, radiators and controls for both the school and the Abbey. Due to the complexity of the work, cost and available time for the actual work (during summer), the entire retrofit work cannot be done between two heating seasons. The following phased approach is recommended: 7.1.2.1 Phase 1

• The existing boiler plant remains as is. • Convert to hot water system only the three storey school building; the Abbey building remains

on steam. • Install a new steam to hot water heat exchanger, circulating pumps and controls to serve the

school portion of the building.


L4C 9Y6 Tel: (905)-787-8885


Page 8 of 20


• Remove all existing steam and condensate piping serving the school. • Remove all cast iron radiators and steam traps from the converted area. • Install new distribution piping, hot water distributed equipment and DDC controls for each

classroom. 7.1.2.2 Phase 2

• The existing boiler plant remain as is. • Convert to hot water system the Abbey portion of the building. • Install a new steam to how water heat exchanger, circulating pumps and controls to serve the

Abbey portion of the building. • Remove all existing steam and condensate piping serving this area. • Remove all cast iron radiators and steam traps from the converted area. • Install new distribution piping, hot water distributed equipment and DDC controls for each

space. 7.1.2.3 Phase 3

• Replace the existing boiler plant with new high efficiency hot water boilers. • Provide new pumps, chemical treatment and DDC controls. • Remove the 2 heat exchangers and install 3-way valves for the control of the two secondary

loops (school and Abbey) • Install a 3rd 3-way valve for the control of the in-floor heating system for the Chapel.

At the end of this retrofit program, the building will have a completely new hot water heating system. The system will be more energy efficient, easier to control individual zones and will require less maintenance. 7.2 School Ventilation System With the exception of the science rooms, the ventilation system for the school is an exhaust only type. Some areas such as the Gym and the Theater have absolutely no ventilation. The majority of the equipment is old, beyond its life expectancy and some is not operational. In order to improve the ventilation system and to bring it up to the current standards required by O.B.C and ASHRAE we are proposing the following options: 7.2.1 Central Make-up air System Due to the small area of existing flat roof and its old structure, installing one large make-up air unit might not be feasible. We are proposing to install two make-up air units with gas fired heat exchanger, heat recovery section, VFD supply and return fans. The roof structure will have to be reviewed and reinforced if required. Two additional shafts will be required from the roof to the basement to distribute the supply air. The available ceiling space at each floor is sufficient to allow for local distribution of ductwork to each classroom. The existing exhaust risers will remain, but the exhaust fans will be removed. The ductwork will be revised in the attic so that the air is returned to the two make-up air units for heat recovery.


L4C 9Y6 Tel: (905)-787-8885


Page 9 of 20


The same make-up air system can serve the pool and the change room area, but the exhaust from these spaces will be either directly to the outside or heat recovery can be considered. To improve the energy efficiency, the supply and return air from each space can be controlled by occupancy sensors. 7.2.2 Individual Unit Ventilators with Heat Recovery This option provides a unit ventilator for each space/ classroom. The unit ventilators can be vertical (if space permits) or horizontal installed above the ceiling. The unit ventilators will be sized to supply the ventilation air requirement for each area. Hot water coils (if the system will be converted to hot water) or steam coils can be used to temper the supply air. The general roof exhaust fans will be removed and the exhaust ducts will be removed or abandoned. The exhaust from each classroom will be done through the heat recovery section of the unit ventilators. Each unit ventilator will require new wall mounted outside air louver Separate units will be installed for the pool and change room. Dehumidification to be considered. This option will not affect the existing roof structure and will not require any additional shafts through the school. The maintenance cost will be higher due to the larger number of equipment and the installation of the louvers will alter the exterior envelope of the building. 7.2.3 Gym and Theater Ventilation System Regardless of which option (described above) will be selected for the school, the ventilation system for the Gym and Theater will be a separate system. We recommend installing two outdoor unitary units c/w gas fired heat exchanger, DX cooling, heat recovery (if possible) and VFDs on the fans. The units will be installed at the back of the Gym (North side) on concrete pads. New shafts will be created inside the Gym for the distribution of the two sets of ducts (one for the Gym unit and one for the Theater unit). Local ductwork distribution and diffusers will be added in each area. Considering that the headroom below or above the running track in the Gym is low, the new unit can be sized for both the cooling and heating loads and eliminate the steam or hot water radiators. The amount of outside air for both units shall be controlled by CO2 sensors. 7.2.4 Shared Facilities Ventilation Some of the main shared facilities that will require ventilation and air conditioning are the Cafeteria, The Senior Girls Lunchroom and the Reception Room. Due to their location, basement or ground floor, these areas cannot be served by a rooftop unit. The occupancy load and the use schedule for these rooms is very different. We recommend considering a separate unit for each area. The units will be outdoor unitary units c/w gas fired heat exchanger, DX cooling, heat recovery (if possible) and VFDs on the fans. The units can be installed in the interior courtyard close to the building. New ductwork distribution will be installed


L4C 9Y6 Tel: (905)-787-8885


Page 10 of 20


from each unit to the respective area. The available ceiling space inside the Abbey building will have to be investigated prior to the detail design of the ductwork system. 7.2.5 Miscellaneous Ventilation Equipment We are proposing to replace all the exhaust fans and controls for the electrical room, small mechanical rooms and other service spaces. The equipment is either too old or is not operational. 7.3 School Air Conditioning System Introducing air conditioning for all classrooms and office areas is not a code requirement but will improve environment in the school during the warm season. The air conditioning can be as part of the selected ventilation system or as a separate system. The following options are being evaluated:

7.3.1 Option1 - Part of the central ventilation system The two make-up air units proposed for central ventilation system will be replaced with two air handling units. The units will still have gas fired heat exchanger, VFDs supply and exhaust fans and heat recovery section, but will incorporate a DX coil and condenser section. The units will be larger and heavier and the airflow requirements will be higher in order to satisfy the cooling loads. The supply ducts will be larger and the existing exhaust risers will have to be replaced to accommodate the new airflows. During the summer the DX section of the unit will modulate to maintain the return air set point. No individual control will be provided for each space. During the winter mode of operation , the gas fired heat exchanger will modulate to maintain the supply air set point temperature. The air will just be tempered, the units will not be used for heating of the space. This option will require extensive renovation inside the school and additional reinforcement of the roof. 7.3.2 Option 2 - Part of the unit ventilators system The unit ventilators can be supplied with a DX coil to overcome the cooling load. The supply air will have to be increased beyond the ventilation air requirements to provide adequate cooling. This option will offer better control of the temperature in each area and will have less impact on the existing school renovation. This system is difficult to implement due to the number of condensers required. There will be approximately 40 condensers. The flat portion of the roof can accommodate very few, the rest would be placed outside around the school. 7.3.3 Option 3 - Separate VRF Air Conditioning System The VRF system is a variable refrigerant split air conditioning system that consists of various type of indoor evaporator, cassette, wall mounted or above ceiling (ducted) and outdoor mounted condensers.


L4C 9Y6 Tel: (905)-787-8885


Page 11 of 20


One condenser system can work with up to 18 indoor units. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The installation of refrigerant lines has less impact on the school and are easier to install. The system as manufactured by Daikin or Mitsubishi is BACnet compatible and can be integrated with any new control system installed for the heating and ventilation system. This type of cooling system can be installed as an addition to either of the ventilation systems proposed above. This type of system is very flexible and can be implemented in phases (one floor at a time) and at a different time than the ventilation or heating upgrade to accommodate budget constraints without compromise the performance. 8 EXISTING LIGHTING SYSTEM

8.1 Lighting System

8.1.1 Overview The existing interior lighting system in school part of building is mixture of recessed/surface/pendant fluorescent and HID Light fixtures. 8.1.2 Light Fixtures distribution

Classrooms typically have either 2’x4’ fluorescent light fixtures recessed in grid where t-bar ceiling is installed and 4’ long surface/pendant mounted fluorescent light fixtures with single lamp and wrap around acrylic lens in areas with no ceiling. Some of the recessed 2’x4’ light fixtures have T8 lamps while others have old T12 lamps. Typically classrooms on the south side have been upgraded to T8 lamps. Corridors at first floor have pendant HID lamp light fixtures. All other floors corridors have surface mounted light fixtures. Control is provided by manual switches. Emergency lighting is provided by battery units and remote mounted quartz lamp heads. Coverage appears to be inadequate in certain areas including corridors and stairs as per present code requirements and good engineering practice and shall be augmented. 9 EXISTING POWER SYSTEM

9.1 Overview The building including School and Abbey are served by an outdoor pad mounted transformer located on west side of property. The main electrical service is rated at 600Amp, 347/600V, 3 Phase, 4 Wire. 9.1.1 Electrical distribution equipment system The 600Amp, 347/600V, 3 Phase, 4 Wire main switchboard is located in Main Electrical Room at Basement level of school part of the building.

Page 12 of 20


112.5Kva step down transformer located in Main Electrical Room serves old electrical distribution equipment located in corridor in front of Cafeteria at basement level. 75Kva and 45Kva step down transformer located in Main Electrical Room serve newer panel in Science Classroom 308 and Room 202 respectively. 600Volt feeder cables from main switchboard serve old electrical distribution equipment located in Sub-Electrical Room (Adjacent to Boiler Room) via 225Kva step down transformer. The electrical distribution equipment in the Sub-Electrical Room appears to serve loads in the Abbey part of the building as well as electrical panels located in corridors of the school part of the building. Additional 600Volt feeders serve 150Kva step down transformer and Infirmary Chiller. Breaker sizes 200A-3P, 150A-3P and 125A-3P serving step-down transformer 225Kva, 150Kva and 112.5Kva respectively are undersized based on recommended minimum rating of 125% of primary current of transformer as per Electrical Safety Code. Most of electrical distribution equipment in School and Abbey part of the building is old (30 years plus) except in Main Electrical Room and other rooms renovated in the recent years. 10 EXISTING FIRE ALARM SYSTEM 10.1 Overview The building including the School and Abbey parts are served by non-addressable single stage zoned fire alarm system. 10.1.1 Fire Alarm Detection & Signal System Fire alarm control panel is located in private office area in the Abbey part of building. Fire alarm annunciator & colored passive graphic is installed in corridor outside the office where the control panel is installed. Automatic detection is provided by heat and smoke detectors. No smoke detectors were observed in corridors of School and Abbey part and shall be considered to be upgraded to meet present code requirements. Audible signals are provided by bells located in corridors. Based on location of bells in common areas such as corridors, it is quite possible that audibility does not meet present code requirement. 11 EXISTING PUBLIC ADDRESS SYSTEM 11.1 Overview The school part of building has public address system manufactured by of Telecor II. 11.1.1 Public Address distribution equipment system Public address system main control cabinet is located in Utility Room on First Floor across from Main Office.
