  Roxboro House

  

  ---

  Background:
  
  Roxboro House is an exclusive Calgary residential community located on the banks of the Elbow River at Fourth Street, gateway to the historical Mission District. The building is minutes from downtown and set amidst some of the cities finest eateries and many tranquil walkways of the Elbow River.
  
  The Application:
  
  After 28 years one of the original building corridor pressurization units required extensive repairs. Rather than fixing the original unit, the Condo Association started looking for new equipment that would improve operating efficiency and temperature control. The original unit was located in a service well mounted high above the parkade entrance ramp. This made access to the equipment extremely difficult.
  
  The Challenge:
  
  The equipment service well could not be expanded to provide more room for the new equipment because of its location. The new equipment had to fit into the existing location and maintain building code clearances. Supply and outside air ductwork locations could not be changed. The old equipment also included a DX cooling coil and separate condenser section which meant mechanical cooling also had to be included.
  
  The Solution:
  
  Working with the installing contractor, Engineered Air sales proposed a custom model DJ100/O as the replacement unit. Because of the limited equipment space, it was not feasible to propose a packaged heat/cool unit or a new condensing unit. It was decided by the installing contractor to keep the existing condensing unit and match it with a new DX cooling coil in the DJ100/O.
  
  The new DJ100 /O was built with custom dimensions to meet the service well space constraints and match the existing duct connections.
  
  Conclusion:
  
  The unit was installed in the existing space and meets building code and maintenance access requirements. The existing condensing unit was installed on top of the DJ100/O. The Roxboro tenants now have a new building corridor pressurization unit with improved efficiency and greatly improved temperature control.
