The Color Court building, which houses ETI’s Lincoln office, is a showcase of mechanical and electrical innovation and green practices. Built to LEED platinum standards, this building was converted from the Lincoln Paint and Color warehouse to a four story office building while preserving historic character. Throughout Color Court you will find reused building materials, including recycled wood and glass features. The building features daylighting, a green roof, rainwater collection, and geothermal heating and cooling. The structure has a 30 percent energy cost reduction, 40 percent water use reduction, and 37 percent reduction in rainwater runoff. The Downtown Lincoln Association's Impact Award was awarded for the renovation work.
This Lincoln Landmark is one of the most recognizable entertainment districts in Lincoln. With multiple restaurants, bars, office spaces, entertainment venues, a public market, and year-round outdoor space, ETI was involved with or did complete MEP work on many of the buildings to ensure success for a variety of different clients and events.
The NebraskaLand National Bank is heated and cooled by a geothermal water source heat pump system and the design incorporates added in-floor radiant heating and an energy recovery ventilation system. An emergency generator can completely power the facility with the loss of city electricity and the communications and IT rooms serve as the main systems for all of NebraskaLand’s banks.
The Joint Forces Headquarters is a 135,000 ft2 building which acts as the command post for the National Guard, State Patrol, and the Nebraska Emergency Management Association during times of crisis. All critical communication systems for the forces are housed in this complex, so reliability and redundancy are imperative. The building’s data center was designed with backup 750 KW generator. High efficiency lighting with less heat gain and UPS was used throughout the building.
The 7,380 ft2 Southwest Iowa Law Enforcement Training Facility provides multi-purpose classroom offices, support space, two 10-lane 25 yard indoor firing ranges, and a 10-lane 50 yard firing range. Engineering Technologies, Inc. designed a mechanical system that consists of gas fired rooftop units for the multi-purpose classrooms and support space. The electrical work included a new 600-amp, 277/480 volt service, fluorescent lighting in all areas except the indoor firing range. In the range, rows of dimmable incandescent light fixtures were specified between the baffles at the ceiling.
This one-of-a-kind facility is a 11,825 ft2 renovation of an existing facility on the UNMC campus for a new current Good Manufacturing Practices (cGMP) Transplant Production Facility. This new facility processes human and animal organs, tissues and cells, and genetically modified projects to enable the creation of engineered cells and tissues for standard of care and IND therapies. A new AHU system was designed for Class 100 Clean Rooms, as well as Class 10,000 Clean Rooms. All areas met cGMP standards for particle counts. 100% outside air was provided to the clean room environments with exact air change roles required to provide the necessary level of cleanliness, and pressure monitoring and control was provided at all entrances and exits to the spaces.
The historic Whittier Junior High School was renovated for the University of Nebraska-Lincoln Energy and Transportation Research Departments. Both were designed to LEED Silver standards. The project was awarded the Lincoln-Lancaster County Environmental Leadership Award for an example of adaptive reuse and demonstrating how to incorporate sustainable practices through construction design, policy, and planning. All of the systems were replaced, but because of the age of the building, a lot of verification of the existing structural constraints was required to assure routing of new systems was possible. This project incorporated UNL’s first geothermal design into their existing campus standards of fan array, variable air volume air handling systems.
The new volleyball arena was designed to provide the best venue for spectating. New LED lighting systems were designed to provide appropriate lighting levels throughout the court area, including horizontal lighting, so no shadows are cast. Much of the plumbing and electrical distribution system was upgraded and the building was brought up to current safety code, including a new smoke evacuation system for the entire arena and concourse levels, fire alarm and fire sprinkler upgrades, a new emergency generator system, and new electronic temperature controls.
This six-story building includes retail and restaurants on the ground floor and 71 one-four bedroom loft-style layouts ranging from 510 to over 1,500 SF in size on the upper five floors. Features include a clubhouse, fitness center, gated access, and high speed, wireless Internet access.
A renovation, addition, and IAQ overhaul was done while the facility was in-use. A new high efficiency geothermal heat pump system was put in to heat and cool the facility, and a new Direct Digital Controlled (DDC) building management system was put in place to provide energy savings. Individual zoning of classrooms allowed a temperature control sensor tied to that individual zone to be linked to the building management system, to allowed individual zones to be heated and cooled for student comfort. Outdoor air was introduced to the facility and heat recovery was used to recapture exhausted energy. New energy efficient lighting was specified throughout the entire facility. The telecommunications wiring was updated and new general purpose receptacles were added.
The historic Duncan Field in Hastings, NE received a $2 million renovation and is used for collegiate, high school, and youth baseball, as well as high school football. Renovation included new bleachers, dugouts, athletic field lighting and concourse lighting, restrooms, locker rooms, training rooms, concessions, and a facility maintenance building. The upper concourse includes picnic areas for spectators that provide excellent views of the field.
