BACKGROUND: In early 2011, the City of Kitchener enlisted the service of IRC Building Science Group Inc. to complete an audit and condition analysis of the Kitchener Auditorium Memorial Complex Facilities. The Complex is a 60 year old main arena, with various additions and modifications over the years. The purpose of the audit was to gather comprehensive information regarding the facility, to ensure City of Kitchener requirements could be incorporated into any plans that the KRHC had to expand or modify the facility. The scope of the review was limited to examining existing facilities/components and providing recommendations on replacement; lifecycle and 5-1 1 Staff Re ort p Krr~.~-~~,i~iER ~nfrastru~ture Servrces Department www.kitthenerta cost. The scope did not include new design or significant changes to the complex or its components. The audit did not involve any intrusive testing. The results of the building audit were presented to Community and Infrastructure Committee on September 26t" as part of the information council requested relative to the KRHC request for an expanded Aud. The committee was advised that $23 million in capital replacements would be required over the next 20 years to maintain the facility and its sophisticated operating systems. It was made clear that regardless whether council approved the expansion that this level of investment would be required. During the meeting on September 26t" one of the areas that council asked staff to look at advancing was improvements to andlor replacement of the ice delivery systems. This report responds to that request. REPORT: It has become increasingly difficult for staff to utilize the existing building systems to ensure quality ice conditions in the Dom Cardillo Arena at the Auditorium forthe following reasons: • the number of spectators has increased significantly over the last 10 years. Average attendance has nearly doubled and this impacts building temperature and humidity, key factors in maintaining quality ice surfaces • the original mechanical and controls systems are 30 years old and have been incrementally augmented and repaired over the years. There is an increasing degree of unreliability with the control systems • as the building has been expanded over the years there are additional spaces and volume that have been added, putting pressure on the systems that exist to the extent some of these systems are incapable of meeting the required standards. Staff undertake post game surveys of ice conditions following every Ontario Hockey League game. The conditions are regularly ranked as poor to average. Quality ice conditions are critical not only to the entertainment value by improving the way the game is played but it also is an important safety element for the players. The ice making plants are sufficiently configured to deliver the required conditions for quality ice making. The one area where staff is unable to provide the required conditions that lead to acceptable ice conditions is achieving and maintaining the temperature and level of humidity both before and during games. If we don't deal with the de-humidification and building controls issues, we will be putting building systems in jeopardy regardless of whether the building is expanded or not. These issues will become even more significant if we expand Cardillo Arena and continue with a piecemeal approach. Staff reviewed internally and with mechanical experts the specific requirements to improve the de-humidification and building controls for the facility. This work included an analysis in conjunction with the proposed expansion design, to ensure recommended improvements would augment the design. The recommended action is as follows: • Replace the existing de-humidification units with new desiccant units as outlined in Option C of the attached Appendix 1 : Estimate of $1,300,000 construction budget 5-2 1 Staff Re ort p Krr~.~-~~,i~iER ~nfrastru~ture Servrces Department www.kitthenerta plus $200,000 in structural and roof repairs (identified by the general constructionldesigntesm) for a total of $1,500,000 construction budget • Replace existing Building Controls system as outlined in the attached Appendix 2: Estimate of $750,000 construction budget • Total Project cost: $2,250,000 + $300,000 (design fees and administration) _ $2, 550, 000 There are several advantages to undertaking this work at the same time as the expansion project the KRHC has proposed: • Economies of scale: the expansion project will affect the major mechanical & electrical systems. The improvements to de-humidification and controls can easily be incorporated into the design rather than conducting a supplementary design, mobilization and construction project. • Role of the Constructor: incorporating all of the work under one overseeing body ensures the City or the Rangers do not find themselves in the role of the constructor, with multiple contractors under multiple contracts on site. This role carries with it additional liability and logistics. • Disruption: If the work is not incorporated into the overall expansion project, the City would need to conduct their work following the expansion project. If the 2 bodies of work were completed consecutively rather than concurrently, there would be extended disruption to occupants and programming and the timeline as laid out by the KRHC proposal could not be met. The KRHC suggested their proposed expansion be a transitional solution fora 15 year period. The recommendations outlined above ensure we have proper mechanical systems for the medium-longer term occupancy of this facility. ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN: This report aligns with two community priorities identified in the City of Kitchener Strategic Plan. These are as follows: Leadership and Community Engagement -Work with funding partners to address gaps in grant funding for individuals and groups in the community. Development- Maintain a balanced approach to replacing and/or expanding existing infrastructure and building new infrastructure. Quality of Life -Provide the community amenities such as community centres and leisure facilities 5-3 1 Staff Re ort p Krr~.~-~~,i~iER ~nfrastru~ture Servrces Department www.kitthenerta FINANCIAL IMPLICATIONS: A total budget of $2,550,000 is required to complete these projects. These are high level estimates meaning there could be a variance of up to 20%. Staff reviewed the upcoming capital program and identified $868,000 which could be dedicated to the Aud dehumidification project in 201212013. As well, staff reviewed existing balances and identified $532,000 that could be taken from capital and reserves. Together, this amounts to $1.4M that could be available from City sources in 201212013. There is no identified City funding source identified for the $1.15M remaining balance ($2.55M - $1.4M = $1.15M) of the Aud dehumidification project. The Kitchener Rangers were approached by the City about funding a portion of the dehumidification project and agreed to provide $960,000 of funding over a 12 year span. This amount of funding would be able to service a debt issue of approximately $800,000, meaning the unfunded balance for this project is reduced to $350,000. If given direction to do so, staff are prepared to review funding options for the remaining $350,000 as part of the 2012 budget process. The following chart outlines the potential funding sources mentioned above.

Kitchener Memorial Auditorium HVAC & Dehumidification Review 1.0 INTRODUCTION The City of Kitchener requested DEI & Associates Inc. to review the heating, ventilation and air conditioning (HVAC} at the Dom Cardillo Arena with respect to the benefits of providing desiccant dehumidification system for the proposed addition. The city and Kitchener Rangers hockey club were having concerns with the potential deterioration of the ice surface due to the humidity in the arena bowl. The purpose of this review is to determine if the existing HVAC system methodology, that is, a refrigerant based cooling system, has the ability to properly maintain acceptable temperature and humidity levels in the bowl as mandated by the current National Hockey League (NHL} standards. 2.0 BUILDING HISTORY The facility was constructed circa 1951 and is owned by the City of Kitchener. In 2001 a major renovationlupgrade was undertaken to provide additional seating capacity. This renovation included private boxes on the west and north side of the bowl, a restaurant on the building south side, and general building upgrades. The goal was to enhance the facility to an appropriate venue for the city in which to improve revenue by attracting larger productions, and also to provide improvements for the Kitchener Rangers hockey club. 3.0 EXISTING HVAC SYSTEM Prior to the 2001 renovation, ventilation was provided via six (d} large exhaust fans in the upper level of the bowl. Although four (4} dehumidification units were installed in each corner of the bowl, there was no other supply air ventilation. In the 2001 renovation, four (4} 9,442 lls (20,U00 cfm} refrigerant based HVAC units were provided for the bowl. Air was distributed at high level throughout the facility. This system was chosen by the design team based on the economy of installation, and the ability to provide adequate temperature and humidity control during the winter hockey season. The system was designed to provide a 21°C (70°F} pre game space temperature. The private boxes were ventilated, heated, and cooled via dedicated packaged roof top gas fired HVAC units. A major challenge with adding any HVAC system to an existing facility is the existing building physical construction. There are certain limitations in this facility in which to provide additional equipment and ductwork in an atheistically pleasing manner. Page 2 of 7 S DEI ~ Associates Inc. Kitchener Memorial Auditorium HVAC & Dehumidif cation Review 4.0 DEHUMIDIFICATION METHODOLOGY Prior to 2004, spectator arenas have generally used traditional mechanical HVAC equipment which utilize refrigerant based cooling and gas fired reheat for dehumidification and temperature control. There were no standard guidelines for large spectator hockey venues and the industry accepted design parameters were generally 21 °C (?0°F) at 50% relative humidity (RH}. In March 2004 the National Hockey League (NHL} issued a memorandum which stated: "T'he temperature and humidity levels need to be controlled and must be achieved and stabilized at least three ~3~ hours before game time. ~'he following are temperature and humidity levels that must be maintained in alt buildings throughout the Playoffs. 1 ~ Air temperature must be stabilized at I5.5°C {6o°F}. and in no event should go higher than 18.3°C (65°F~. 2~ Humidity levels must be at less than 45% RH. Furthermore, though most air conditioning systems remove moisture from the air, air conditioning atone may not remove enough moisture from the air to produce acceptable humidity levels. 7~erefore, your building may be required to add a portable ~desiccant~ dehumidification system in order to be able to reach the required levels. " These new design parameters were issued not only to standardize all arenas but also to improve the ice surface and arena conditions for large spectator and professional hockey arenas. The goal is to reduce the humidity above the ice surface to reduce condensation and frosting on the ice surface. Further to this memo the NHL has requested a 15.5°C (b0°F} 35% RH pre-game condition and a 18.3°C (b5°F} 45% RH post-game condition. These conditions can not be achieved with a refrigerant based HVAC system. Most new state of the art ice arenas have incorporated desiccant dehumidification systems to control space temperature and humidity. It is not uncommon for older arenas (i.e. Hersey Centxe in Mississauga and Varsity Arena in Toronto} to have modified their existing refrigerant based systems to incorporate a desiccant dehumidification system to enhance the environment of the facility. Page 3 of 7 DEI & Associates Inc. Kitchener Memoriai Auditorium HVAC & Dehumidification Review 5.0 EXISTING SYSTEM INFORMATION We spoke with the building operator and staff to determine how the building is currently operated. The space temperatures and humidity levels were recorded on October 7, 2411 at 8:00 p.m. during a Kitchener Rangers hockey game and the results are as follows. The space pre cooled to 15.5°C ~6D°F} prior to game time. The units operate in a recirculation mode throughout the game to maintain space temperature. East Bowl Space temperature 17.7°C X64°F} Supply air temperature 5°C X46.6°F} Return air temperature 19°C (66.4°F} Outdoor air temperature 17°C X62.4°F} Relative humidity 57% West Bowl Space temperature 17,2°C X63°F} Supply air temperature 8.3°C (47°F} Return air temperature 18.5°C (66°F} Outdoor air temperature 17°C (62.4°F) Relative humidity 60% All values are averaged between the two corresponding units on each side. 6.0 BUILDING DESIGN CONCEPT The construction budget for the new expanded seating was based on relocating the two (2} existing HVAC units to the new roof and adding an additional refrigerant based HVAC unit to the east side. The existing HVAC units on the west side were to remain as installed. This initial design would provide proper ventilation and maintain the current space temperature and humidity levels. There was no mandate to provide desiccant dehumidification units. 1t has since been determined, via apre-construction meeting design meeting, the arena would now be designed for 5,000 people, and that it was the intention of the building owners and operators, that the arena temperature and humidity levels would now be designed to current NHL standards. Page 4 of 7 DI~I & Associates Inc. Kitchener Memorial Auditorium HVAC & Dehumidification Review 7.0 CONCLUSION The existing refrigerant based HVAC system was not designed to provide post game conditions of 13.3°C X65°F} 45% RH. The units cannot currently maintain the required 8.8°C (48°F} supply air temperature nor do they have the capability to properly dehumidify the air and maintain proper space and humidity conditions to meet the current NHL standards. The existing units should only be utilized far perimeter systems ~i.e. concourse, shops, etc.} unless the existing HVAC units can be modified to provide adequate sensible coaling. 8.0 DESIGN CONSIDERATIONS Although the refrigeration plant is the heart of the arena, humidity, temperature, and proper ventilation are crucial in providing a comfortable environment. Humidity control is vital to the prevention of moisture problems including fog, soft ice, damage to building structure, and other condensation problems. Temperature control is required to provide a comfortable environment for the patrons, and proper ventilation is required to maintain goad air quality. Air quality is affected by the emission of people and the ice resurfacers which are run by a combustion engine. The new facility will bring the total number of seats to 7,268. when standing roam is included the capacity will be 7,800 people. To provide a properly ventilated facility to meet ASHRAE 90. i standards, 3.54 lls X7.5 cfm (cubic feet per minute}} of outdoor air per person is required. At a design capacity of 7,804 patrons, along with players, operators, and staff, the facility will be designed for 8,000 people. The required design outdoor air will be 8,000 people x 3.5 Vs cfmlperson = 2$,000 lls (60,000 cfm}. In order to meet the design requirements the NHL standard of a pre-game design criteria ~ 15.5°C 35% RH} and past-game design criteria (18.3°C 45% RH} a desiccant dehumidification system with heating and cooling is required. The 2001 renovation was designed for 5,500 patrons excluding the suites and private boxes, and was designed to maintain a space temperature of 21 °C X70°F}. The four ~4} existing HVAC units do not have the capability of supplying the required air volume to maintain space temperatures for the addition. An additional 18,885 lls (40,000 cfm} of supply air to the building is required to satisfy the space temperature. A desiccant dehumidification system with heating and cooling will achieve the proper humidity, temperature, and ventilation required for this facility. The desiccant system operates through the use of materials that can remove moisture from the air. The system utilizes a rotating wheel that is coated with an absorbent material (silica gel}. Moist air is drawn across 75% of the wheel where the desiccant absorbs moisture from the air. As the wheel rotates it passes through a heated air stream atypically gas driven} and moisture absorbed by the desiccant is released into the heated air. The warm moist air is then exhausted to atmosphere. -10 Page 5 0~ DEI & Associates Inc. Kitchener Memorial Auditorium HVAC & Dehumidification Review 9.0 SYSTEM OPTIONS In order to improve the temperature, humidity, and ventilation andlor to meet the current NHL standards we are providing the following options. A final detailed design and budget will be required when a design option has been accepted. Option `A' (SKM-1, SKM-2} Provide one (1 } 18,885 lls (40,000 cfm} roof mounted desiccant dehumidification unit and one sensible cooling unit on the new roof on the east side of the building to provide 37,770 lls (40,000 cfm} of total air and 9,440 lls (20,000 cfm} of outdoor air. The existing HVAC units on the west side of the building will be modified and will be used for recirculated air distribution and sensible cooling only, however, depending on the outdoor temperature and humidity, the building conditions maybe adversely affected. This option will provide a quality environment for approximately 95°Io of the time but can not guarantee the required temperature, humidity, and ventilation will meet the NHL standards. The existing units could be replaced in the future with proper desiccant dehumidification units. An HVAC Class `C' construction budget of $550,000.00 is estimated for this option. Note: since this option utilizes existing equipment the life expectancy on the existing equipment is not guaranteed. It is not practical to use the existing equipment especially if, due to the age of the equipment, the life expectancy of the equipment is uncertain. Uption `B' (SKM-1, SKM-3} Provide one (1} 18,885 lls (40,000 cfm} desiccant unit and one (1} 18,8$5 lls (40,440 cfm) HVAC unit with a 9,440 lls (24,000 cfm} desiccant wheel on new roof on the east side of the building and provide a new 9,44011s (20,040 cfm} desiccant system on the west side of the building. The west side desiccant dehumidification system would be incorporated into the existing refrigerant based HVAC units, The desiccant system would dehumidify and cool the air and the existing modified roof-top HVAC units* would provide the heating requirements. This option would provide the required temperature, humidity, and ventilation to meet the NHL standards. An HVAC Class `C' construction budget of $1,400,000.00 is estimated for this option. 'Note: since this option utilizes existing equipment the life expectancy on the existing equipment is not guaranteed. It is not practical to use the existing equipment especially if, due to the age of the equipment, the life expectancy of the equipment is uncertain. Uption `C' (SKM-1, SKM-4} Provide one (I) 1$,885 lls (40,000 cfm} desiccant unit and one (1 } 18,885 lls (40,440 cfm} HVAC unit with a 9,440 lls (20,000 cfm} desiccant wheel on the new roof on the east side of the building plus replace one (1}existing HVAC units with a 9,444 lls (20,000 cfm} desiccant dehumidification unit and provide a 9,440 lls (20,400 cfm} sensible cooling unit in place of the other existing unit. Minor ductwork modifications on the existing ductwork are required to provide proper air distribution. This option would provide the proper required temperature, humidity, and ventilation to meet the NHL standards. An HVAC Class `C' construction budget of $1,340,000.00 is estimated for this option. -11 Page 6 0 DEI & Associates inc. Kitchener Memorial Auditorium HVAC & Dehumidification Review Dption `D' ~SKM-5~ Provide one (1 } 28,000 lls X60,000 cfm~ desiccant dehumidification unit on the new roof on the east side and one ~ 1) 28,000 lls X60,000 cfm} desiccant dehumidification unit on the west side. This option would provide the proper temperature humidity and ventilation to meet current NHL standards. This is a viable option however ductwork considerations on the west side of the bowl may be an issue. An HVAC Class `C' construction budget of $1,500,000.44 is estimated for this option, 10.0 RECOMMENDATIONS We recommend Option `C' for this facility. This option would provide the proper temperature, humidity control, and ventilation to meet NHL standards by replacing the two (2} existing units on the west side and utilizing the existing ductwork with minor modifications). Interior renovations on the west side, including any structural modifications, would be minimal. -12 Page 7 0~ i ~ P - ~ ~~ - ~~. i A ~~~ u ~~ ~~ I ~ ~ ~k.,~ 4~,e9 ~ g I I ~. 0 i ' M i i L_____ o~ ~~~;~s Z '°~ ~~ ~; o~ s ~J `'y ~8~ ~ ~~ ~~ NC '-~~_ ~ C ~ N 4 ~ ~, ~; J~ 11 ~~ ~ , rvt ~.~y '~ ~ i ~ ~~ ~ x ~1 ~~ , ~~~'_ ~ 3 ~ ~ ~ ~ i•x W ~,- ~~x ~ ~, a ~ a x',~~ a x~ E~ ~o~ ~o~~ ~~ ~ ~ 1~~a ~i ~~ c'ti ~ x ~ ~~ ~ ~o ~ ,, ~., °,Nas y ~ oa ~ ^~ ~ .~~ ~ L Q "4 r ~'Y~'~ m (~ ~ I o k f I~I iq ~ ~~ p G °~ ~ mt1 ~ .., _ - ~_ r T ~Z~ .r~x, V I, ixW~ i ~~~ ~ I~O;- ~Or`" ~~;~ a i ~~ 0 0 o ~ ~ ~ ~ x ~ m` o ,l ~~ ~~ ~. ~o ~~~; ~ mj ~:_~ NI r of ~ ~ o~ ~~ ~ ~~ I` i I CV x, f 'r~'rAASS`~'r: Ir_IrAASS` ~~ W~ W~' ~~ ~~ ~ '~ ~Z~ ~ ~ZZ ~d;° ~o ~~ I~ .xW~ '~xfl~ az x x ~ ~y ~F~ ~O ~'~ O"~ x J f rOna~ t0 td ilj ~ , p ~ ~ _... .F _:_ .. y.. ~ ~. ~.. ,:. x= ` f t Z ~ ~: ~ ~~~ ~~~ oFy Id ~ a ~ °/ r, UUIM ~ UNM_ ~ § ~ N' r z . /' r '.

Kitchener, Ontario N2G 4G7 Attn.: Ms. Cynthia Fletcher Bang., BSS4, Director, Facilities Management Re: Kitchener Memorial Auditorium Expansion Building Automation System Kitchener, Ontario Dear Madam: The City of Kitchener requested D11I & Associates Inc. to review the Building Automation System (BAS} at the Memorial Auditorium Complex (Aud}. The city was having concerns that the BAS system. did not have the ability to control all aspects of the building. The purpose of this review is to determine if the BAS system has the ability to properly control the new and existing systems andlor if the existing system requires upgrading. A construction cost of approximately $~00,000.o0 would be required to install a new BAS system in a similar type of facility, and to replace the existing BAS system currently installed in the Auditorium complex a Class `C' construction budget of $750,000.00 would be required. The existing Building Automation System (BAS} installed in the auditorium complex is a web based I~oneywell control. system installed by Accutemp Controls lnc. The control system utilizes Honeywell XL 500 zone controllers (approximately 500 C-BUS control points} XL IGU zone controllers (approximately 100 C-BUS control points} and Honeywell XL 50 zone controllers (approximately 50 C-BUS control points} to control all of the equipment in the facility. each L4N control point provides a control function or duty (i.e, temperature set point, system on-off operation, damper control, etc.}.The controllers are interconnected to a "bus" which communicates with the Niagara Frameworks 522 (RZ} Operating System (front end} through an operating device (i.e. personal computer} to command the connected building equipment to perform its required functions. Approximately three years ago the Central Processing Units (CPU's} on the zone controllers, that is the controllers operating the equipment, were updated to C-BUS Local Operating Network (LGN} controllers. The controllers are daisy chained together, which also causes operator wait times. ane of the main issues is that not all of the equipment in one area, or all of the points for one piece of equipment (dampers, valves, etc.}, are connected to a common controller and were connected to any available point. This causes the operator some frustration looking for a particular point or piece of equipment. There are currently fifteen (15} ~L 50 controllers, four (4} ~L 540 controllers, and one ~L 100 controllers in use on site. The ~L 50 controllers are at maximum capacity and the XL 540 controllers are at approximately 90°10 capacity. While there is space for additional LQN points, the C-BUS points are at near capacity. Pal of 2 DES & Associates tnc. Kitchener Memorial Auditorium BAS Letter All of the equipment functions are connected to the BAS system. Some equipment set points ~i.e. steam boiler pressure differential, steam boiler low pressure, steam boiler high pressure} are only communicating on the C-BUS network and do not exist on the LQN network, due to controller space limitations. These points could be communicating on the LAN network web front end} with the addition of new ~L 500 controllers or by adding Honeywell's new C-BUS driver, The facility is currently operated by the building operator and is not operated through The City of Kitchener facilities' department. we recommend replacing the entire building automation system in the facility. The new system would provide the latest technology with the latest system equipment utilizing the preferred BAS system as dictated by the City with a Class `C' construction budget of $750,000.00. This option will also provide the required system training, graphics, and system commissioning. The new system will have the ability to link this building with other City owned facilities. we trust the above is satisfactory. If you require any further information please do not hesitate to contact our office. son C.Q.T. :er Revised re BAS oct 19-1 l.doc City of Kitchener, Mr. Keith Baulk Pa~ of 2 Yours truly,
