Location:  Minneapolis, Minnesota
Total Cost:  $12 Million
Square Footage:  30,000
Completed: 2014

Project Description

Engineering Design Initiative designed the electrical, lighting, power, HVAC, plumbing, fire protection, voice/data, security, sound and closed circuit television systems.  Engineering Design Initiative also provided the energy and daylight modeling for the facility.

This state-of-the-art library includes many creative and sustainable engineering systems that are estimated to exceed the MN Energy Code by greater than 45%.   Building features include:

  • High efficiency hot water boilers
  • Underfloor (raised floor) Air Distribution System with pressurized plenum that resulted in no ductwork in open areas.  The UFAD also included electrical and communications cabling.
  • LED lighting throughout the facility with daylight harvesting to reduce energy consumption
  • Energy recovery for exhaust air.
  • Occupancy sensors for lighting and ventilation control
  • Central emergency lighting inverter to minimize maintenance
  • High efficiency motors with variable frequency drives for fans and pumps
  • Building-wide programmable lighting control system to reduce electrical usage
  • Fiber-optic communications “ring” topology for redundant communications
  • Audio / Visual in meeting rooms
  • Communications cabling and wireless access throughout facility.
  • Zero use of HCFC refrigerant
  • Exterior hydronic snow melt system for vehicle ramp and pedestrian areas
