5 1. INTRODUCTION This report establishes a quality level and degree of completeness for the project. This information will be refined and modified by Artec Consultants Inc, in collaboration with the other members of the Design/Construction Team during the design process, before construction commences. This report lists the expected electrical power and HVAC loads of performance related systems for Production Lighting and Motorized Theatrical Equipment in the East Harbour Concert Hall and Congress Center for the following spaces: The Concert Hall ("CH"); The divisible Conference Hall ("DCH"); The Recital / Rehearsal Hall ("RR"); The Fourth Hall ("FH"), and; The Lobby areas ("L") This report covers only these performance spaces and their related auxiliary spaces. Lighting, general power, and HVAC requirements for lobbies, public areas or other spaces are not included in this report. However, company switches have been allotted to the main lobby zones for the temporary power needs of special events produced in those areas. Refer to Artec report K. Guidelines for Electrical Design of Performance-Related Systems, in the PFI Tender Documents, Appendix I: Concert and Conference Facilities Planning document which was issued on 9 December 2005 for information regarding the special electrical design requirements for each system. Refer to Artec report 7731: Electrical Power and HVAC Load Requirements for Sound and Communication Systems for information on Sound and Communication system requirements. Performance equipment will be idle much of the time, but during periods of high activity most of it will be used simultaneously. Electrical power loads are given in Kilowatts (kw) for electronic equipment, and in Horsepower (H) for motors. Loads given are anticipated maximum demands, including anticipated diversities within each system. Additional diversities between the various systems are noted where applicable. Any code required deratings or start-up loads are not included in the loads given. Amperage is indicated where industry standards exist. Otherwise, conversion to ampacity and determination of wiring and protection sizes are the responsibility of the Electrical Engineer. To reiterate: this is a preliminary introduction to the power requirements for these specialized systems. Values will necessarily be refined and modified as the design of the facility and the systems proceeds. REPORT NO ARTEC CONSULTANTS INC PAGE 1

26 5. HVAC LOADS 5.1. INTRODUCTION Performance and Audience Spaces The heat loads listed for the various performance spaces are based on the expected use of the various performance related systems. Heat loads from people are not included in these figures. All information is based on design information currently available, and is provided to allow the design parameters for the air handling system to be calculated. Heat loads may vary, based on the exact equipment chosen, but should remain within the ranges noted. It is possible that appreciable changes will be noted as design progresses. Other than people, Production Lighting is the principle source of heat loads on the concert platforms or within audience areas. Other performance related equipment has a minimal effect on these loads, and can be considered to be included in the figures given for lighting Equipment and Control Rooms Heat loads vary tremendously in equipment and control rooms, depending on usage. Production Lighting Panels and Control Consoles are low wattage and will not be a significant contributor to heat load. Control Rooms may include sound and communication system racks which may provide more significant heat values. Sound and Communication System information is provided separately in Artec report 7731: Electrical Power and HVAC Load Requirements for Sound and Communication Systems. Electronic control equipment is quite sensitive to temperatures and humidities above specified working ranges. Therefore, and because control rooms may develop significant people load, we recommend separate HVAC control to allow these rooms to be maintained at maximum ambient temperature of approximately degrees Celsius, and at a maximum 50%-60% relative humidity, even during periods when the majority of the building is not in use Concert Hall Projection and Followspot Rooms In the Concert Hall, Projection Room # and Follow Spot Room # will have special HVAC criteria which will need to be developed as the design proceeds, and which is somewhat dependent upon selection of equipment. However, at the current stage of design, equipment heat loads for these rooms (when the equipment is being used) can be considered as approximately 10KW in each case. In addition, both of these rooms will require separate exhaust systems since Xenon and other arc-lamp types for followspots produce nominal amounts of ozone HEAT LOADS: CONCERT HALL "CH - PLATFORM AND AUDIENCE CHAMBER Note: The auditorium heat load will depend on the architectural lighting design of the House Lighting system (to be determined) - that value is not included here.

Total PL Load Platform PL (80%) Auditorium PL (20%) 70 kw 56 kw 14 kw 5.4. HEAT LOADS: CONFERENCE HALL DCH Total PL Load 80 kw 5.5. HEAT LOADS: FOURTH HALL FH Total PL Load 5.6. HEAT LOADS: DIMMER ROOM 50 kw Note: The Dimmer Room (or rooms) should have a separate HVAC supply sufficient to maintain a maximum ambient temperature range of 20 o to 24 o degrees Celsius and a maximum 50% relative humidity at all times regardless of whether equipment is in operation. Quiescent: Figures are based upon a maximum loss of 6 Watts per dimmer while equipment is idle. If all dimmer slots are occupied there will be a total of 768 dimmers in this room*. Losses in relay and transfer panel racks should be added to this total. Estimated Quiescent heat losses are ± 4 kw. *This assumes a Central Dimmer Room for all performance spaces. Average: Figures are based upon fifty percent (50%) of the estimated PL load being in use at any one time over a performance period of two to three hours and assuming internal dimmer loss of no more than 8% during this operation. Estimated Average heat losses are ± 4 kw (Quiescent) plus 8 kw or 12 kw. Peak: Figures are based upon seventy-five percent (75%) of the estimated PL loads in use at any one time over a performance period of two to three hours and assuming internal dimmer loss of no more than 8% during this operation. Estimated Peak heat losses are ± 4 kw (Quiescent) plus 12 kw or 16 kw. END OF REPORT REPORT NO ARTEC CONSULTANTS INC PAGE 23
