The 1201 Cass tenant improvement project is the first WELL Certified™ Gold project in Nebraska. It is also the first Wired Certified Platinum space in Nebraska. “Engineering on display” was one of the main themes throughout this project as the mechanical, electrical, plumbing, and technology design firm wanted clients and visitors to be able to experience these systems firsthand in areas specifically designed for demonstration.


  • 2020 ACEC Nebraska Honor Award and Best-in-Category for MEP systems, Merit Award for technology systems, and Merit Award for acoustics
  • 2020 AEI Honor Award for lighting systems design and Merit Award for mechanical systems design
  • 2020 Durham Outstanding Alumni Project Award — interdisciplinary category
  • Under-floor air distribution system is supplied by individual floor air handling units with manually adjustable swirl diffusers at each occupant’s work station and in common areas. To address rooms with varying load conditions, floor swirl diffusers with motorized dampers are used to vary the amount of supply air for cooling.
  • The lighting control system is integrated with many other building systems including the automated shade systems, occupancy sensors for the security system, zone and scene control on the audiovisual touchscreen controllers in conference rooms, and the Building Management and Control System which manipulates color changing fixtures at the reception desk based on outside air temperature and wind speed.
  • Tunable white fixtures are used in the open office areas, with the sophisticated lighting control system adjusting the color of light based on time of day in an effort to blend cohesively with the significant natural daylight pouring in through the curtain wall windows surrounding the work stations.
  • The conference rooms are each designed with different lighting fixture solutions to allow architects, owners, and other visitors to visualize how a space might look and demonstrate individual zone control to modulate levels of individual fixture types.
  • The telecommunications infrastructure was designed to provide reliable service and ease of maintenance in the future. The telecom cabling was color coded for each system and bundled in groups of 24 cables dedicated to each patch panel.
  • The electronic access control system was designed to lock doors on a specific time schedule. The system is also the main platform for a fully native integration between the electronic access control system, intrusion detection system, and electronic video surveillance system.
  • The intrusion detection system was designed to be extremely user-friendly for the occupants. The system includes the utilization of the lighting control occupancy sensor for motion detection and an integration with the electronic access control system card readers to allow for one swipe arm/disarm function.
  • Electronic video surveillance system includes IP-based security cameras, storage, network electronics, and virtualized software.
  • Audiovisual systems are included in conference rooms with collaborative wireless screen sharing, software-based videoconferencing, a network-based audio system including IP Power Over Ethernet (POE) powered loudspeakers, and intuitive touch panel controls integrated with the lighting system.
  • Training room includes two large acoustically transparent projection screens, ceiling-mounted and an in-podium confidence monitor, presenter and audience cameras for software based videoconferencing, wireless microphones for presenters, ceiling microphones for audience participation, and wireless audiovisual touch panel control.
  • Acoustical treatments were applied behind the training room’s large projection screens and in conference rooms to minimize noise disruptions.
