AIR BALANCING AT THE AUD - REQUEST FOR FUNDS
RECOMMENDATION:
That $85,000 be provided from Capital Contingency to fund two dedicated air make up
units in the Dom Cardillo Arena at the Kitchener Memorial Auditorium Complex.
BACKGROUND:
There were occasions when ice conditions for Ranger Games in the Dom Cardillo Arena during
September and October 2007 were not ideal. It was felt this was primarily the result of the
effects of warmer outside weather and the ability of the building equipment to keep the building
cool once the doors opened for the patrons. Staff immediately began investigating ways to
address the issue. The investigation included regular consultations with Aud staff, Facility
Management staff, Dan Craig an ice technician from the National Hockey League and other
professional system contractors. It became apparent ice quality issues are very complex and it
would require a number of actions to improve the situation.
Immediate steps were taken to make adjustments to the building air temperatures and the game
day building and ice procedures. In addition to the game day adjustments Totten Sims Hubicki
(TSH) were engaged in November 2007 to undertake an investigation to identify issues affecting
the ability of the existing dehumidification system to function adequately and also to provide
recommendations for upgrades which would improve the indoor air environment at the Dom
Cardillo Arena.
The report from TSH was distributed and reviewed with City staff in December 2007. Based on
the report the following action steps were recommended:
1. Review the overall air balancing within the facility.
2. Establish a priority to cost out the modifications to balance the air in the facility especially
related to the exhausting from the concessions and kitchen.
3. Determine what existing capital funding would be available within Facilities Management and
Aud accounts to fund any improvements.
4. Engage the consultant for further design work for the air make up units for the concessions.

5. Investigate the potential of renting temporary desiccant dehumidifier units for the months of
April and May 2008 for the playoffs and Memorial Cup.
REPORT:
One of the observations made by TSH during their investigation was that the building appeared
to be exhausting a lot more air than it was bringing in which created a significant negative
pressure within the building and encouraged the infiltration of large amounts of warm
unconditioned air into the space. A primary contributor of this condition appears to be the
exhaust hoods in each of the two concessions.
TSH is recommending that these two areas receive dedicated air make up units to compensate
for the amount of air being exhausted by the exhaust hoods at an approximate cost of $25,000
each. In addition to the $50,000 for the units there will be structural work and installation costs
of an additional $35,000 for a sum of $85,000 to complete the work. This item along with
rebalancing of all the ventilation equipment within the Dom Cardillo Arena will help to reduce the
amount of unconditioned air infiltrating the building due to the existing negative condition.
Staff have also been able to secure desiccant dehumidification rental units for temporary
installation in April and May 2008. The costs of the temporary installation and rental will be
funded 500/0 from existing Aud and FM capital accounts and 500/0 from the Memorial Cup
operating budget. This temporary arrangement will allow staff to evaluate the effectiveness of
these units and determine what size and type of equipment may be required on a permanent
basis in the future.
FINANCIAL IMPLICATIONS:
The funding for the $85,000 permanent air make up units and installation will come from capital
contingency funds. The uncommitted balance in Capital Contingency as of March 12, 2008 is
$282,459.
Staff will debrief after the Memorial Cup to determine what additional equipment is needed
permanently and submit the funding request as part of the 2009 capital budget process.
Based on the findings following the debrief session, a temporary solution may be required for
September and October 2008 and depending on the financial implications, may need to be
addressed in a future report to CSD.
CONCLUSION:
Staff are requesting capital contingency funds in the amount of $85,000 to proceed with work to
improve air quality within the Dom Cardillo Arena.
