Project Description

Chase Center on the Riverfront

Griffith Engineering was asked to help a local ESCO develop an energy model for this convention center in Wilmington, DE as part of a performance contract.  A preliminary model had already been developed. However, investigation of this model revealed the previous modeling team could not properly account for the difficult to predict occupancy patterns of an event venue, and they had included false loads to cheat the model into calibrating.  Griffith Engineering was able to rebuild the model and properly calibrate it while accounting for the difficulties inherent in convention centers.  The project included:

  • Replacement of all rooftop package units.  GEI helped the client evaluate different unit alternatives and justify unit downsizing where possible to save money.  New units were evaluated with high efficiency filtration and variable airflow capabilities.
  • Multiple lighting retrofit packages were evaluated.
  • Building automation controls upgrades and intelligent control of ventilation in lobbies, event and theater spaces.
  • Envelope sealing around loading docks and attic insulation upgrades.
  • Model used to help size potential back-up generators for the building.

This project was approx. 200,000 sq ft
