UAS Residence Hall (Student Housing)
With the construction of the new student residence at UAS, Haight & Associates designed intricate schematics to include Power Systems, Lighting Systems, Network/Communications, Television, Fire Detection/Alarms, Access Control and Security.
Power Systems included Utility Service, distribution and branch circuit systems, devices and equipment. Lighting Systems included exterior and interior systems. The exterior is supported with emergency power packs to maintain illumination for a minimum of 90 minutes in the event of a power outage. The interior was designed with surface mounted and recessed lighting fixtures with LED lighting. As this is a LEEDs project, low maintenance LED light engines are utilized for all luminaries in this facility. A 3500 degree K luminance is prominent throughout. Low voltage controls are used with scheduling and occupancy control to limit use during inactive hours.
Network/Communications for the new residence all was integrated with the campus network system using fiber-optic cable. The infrastructure incorporated runways in the electrical room and two terminal stations were installed. Additional network terminals are located in the study, lounge and seminar room to best accommodate the students/professors and guests.
Television service and distribution is routed from the nearest utility source. It is amplified as required for the number of connection points within the building. Each dormitory room is provided with a terminal.
Implementation of an automatic fire detection and alarm system is addressable with initiation and notification devised provided in compliance with the codes. It also incorporates features for the elevator and sprinkler systems.
Access control and security included surveillance cameras, sensors indicating door open conditions and alarms. The cameras are programmed to allow image collection and video streaming when motion is sensed at certain locations. The system allows for storage allowing historic review as needed from monitoring systems.
Mendenhall Valley Public Library
Mendenhall library was completed in 2015. With the construction of the new library, Haight & Associates designed power systems, lighting systems, network & communication and access control. This facility is characterized by a roof that “floats” on columns above windows that surround the perimeter. The lighting objective was to illuminate the spaces open to the upper ceiling utilizing indirect, reflective light and furniture mounted luminaires. No luminaires are mounted in or on the upper ceiling.
All of the lighting for this library utilizes luminaires with LED light engines. The light is produced with a 3500 degree K color and is controlled with a low voltage system using manually selected preset scenarios and dimming of luminaires in specific areas. The roof of library extends well beyond the perimeter of the exterior walls allowing some of the interior light that is directed at the ceiling to also illuminate the eve. This is a LEED project so the light is limited to illuminate no further than the eve.
The primary area of the library is illuminated with linear luminaires mounted to the window structures. These luminaires are directed to illuminate the ceiling, thus reflecting to the floor towards the center of the space. The stacks incorporate linear fixtures mounted at the top and directing light to the floor. These luminaires include emergency battery packs to facilitate egress lighting. Light bars mounted above the study surfaces which provide task illumination.
The children’s library features diagonal cubes built into the wall. The interior of these cubes include recessed linear fixtures providing illumination for bear and Eeyore, as well as the children visiting the library.
The meeting rooms have ceilings constructed below the upper roof. Luminaires are mounted above the soffits, wall, and ceiling providing indirect and direct illumination of the space. This provides uniform illumination of the entire volume.
Seawalk Lighting AJ Cruise Ship Dock
In 2015, we began and completed a project to construct a new seawalk from one of the cruise ship docks toward the town center. It includes several features that incorporate different lighting characteristics. All of the luminaires utilize LED light engines with 3500 and 4000 degree K luminance.
The seawalk originates at the cruise ship dock, passing beneath a translucent canopy. Native totemic art is included with some of the canopy panels. This area is illuminated with small marker lights with narrow beams mounted into the canopy support structure. These provide lines of light across the walkway. The objective in this area is to direct the light downward in a relatively tight pattern. This allows the canopy panels with totemic art to silhouette against the evening sky without distractive artificial light.
A section of the seawalk between the covered portion and a gift shop is featured with garden planters and sitting benches. This is a wide area in the seawalk with small spurs leading landward to a bus parking area. Marker lights are encased into the concrete walls surrounding the planters and supporting the benches. This project lights the walkways in this area.
Three of the photos show straight round poles supporting decorative, period style luminaires. These are located on the water side of the walkway, illuminating the pathway from the canopy to the far end of the project. These luminaires are a cutoff type projecting most of their light directly to the walkway deck. The intent is to facilitate viewing from the seawalk out over the waterfront without objectionable artificial light. The poles include brackets for supporting decorative flags in the summer.

Aurora Harbor is a marina used for rented docking and shore tie power by commercial boat owners. Phase I of the Aurora Harbor Rebuild project consisted of replacing the southern third of the marina. Haight & Associates designed shore tie power distribution, LED lighting, and water pedestal heat trace.
Shore tie power distribution provided separately metered power pedestals at all boat rentals spaces. All power pedestals are powered from one of two separate power centers, which also provide branch circuits for LED lighting, heat trace, the sewer pump, and other associated electrical loads.
Robust LED luminaires were designed to emit precise lighting along the floats and gangways with minimal light pollution and glare. Photoelectric lighting controls secure power to the LED luminaires during daylight hours.
Heat trace was designed to prevent freezing at water pedestals and above ground water piping during cold weather. This provides fresh water throughout the renovated section of the harbor all year.
Haight and Associates completed the design of Aurora Harbor Phase I in March of 2014, and construction was completed in summer of 2015.
State of Alaska UPS
With the reconfiguration of the State UPS, we increased system reliability by eliminating single points of failure on the protected side of the system. We replaced a 300KVA UPS with a 450KVA UPS. The system operates in a typical parallel configuration, and will allow the UPS’s to equally share the load. System controls were reconfigured to synchronize the UPS’s to one another and to the utility. If one of the UPS fails, it will remove itself from the bus-bar, if the second UPS fails, the static switch will pass the load to the utility.
Salmon Creek Filter Plant
The Salmon Creek Filtration Plant provides filtered and treated water to the Salmon Creek reservoir. The new filtration plant was designed to filter, treat, and pump more water to the reservoir via a state of the art filtration system and new water pumps. Haight & Associates designed the power distribution, pump controls, programmable logic controller (PLC) retrofitting, telecommunications, LED lighting, heating, ventilation, filter device communications, and emergency power. Haight and Associates completed the design for the project in June of 2015 and construction was completed in the spring of 2016.
The power distribution consisted of a new power feeder to a new motor control center in the filtration plant and branch circuits to all new electrical loads. The electrical loads in the filtration plant were fed via cables from a fiberglass cable tray.
The existing obsolete programmable logic controllers were retrofitted with new I/O modules, CPUs, and touchscreen-style Human Machine Interfaces (HMI). Telecommunications between all PLCs, VFDs, HMIs, and miscellaneous computers was established via an Ethernet network
Industrial LED lighting was designed for the interior and exterior of the filtration plant. Photoelectric sensors control the exterior lighting, and manual switches control the interior lighting.
Thermostat controlled heating and ventilation control the temperature inside the filtration building. Electric unit heaters with fans and an intake fan with gravity vents keep the interior of the filtration plant at a suitable temperature while providing air exchange.
Emergency power is provided by a battery-equipped Uninterrupted Power Supply (UPS). The filtration building office computer, all PLCs, and a few miscellaneous devices are powered from the UPS.
Sealaska Heritage Institute
Sealaska Heritage Institute is a three-story building with basement includes electrical support for HVAC and pellet boilers as well as distinct lighting, UPS, IT rooms, access control and life safety systems. With the construction of the new building, PDC, Inc. and Haight & Associates designed lighting, power systems, configuration of the lighting controls, network & communication infrastructure, fire alarm system, access control, and security system. AEL&P provides secondary service 208V 3 phase power underground from their vault to the switchboard in the basement Mechanical room. IT rack and AV controls are connected through an UPS providing 18 to 20 minutes of back up power for a safe shutdown.
The fiber optic (backbone) cable from the Sealaska Plaza network addressed with the communications systems facilitates the interconnection between the Sealaska network and the Sealaska Heritage Institute network. There is a cable tray system on each floor with an optimal integration with raceways to the terminals. The cable trays utilize a mono-rail, aluminum construction suspended from the structural ceiling.
Lighting throughout utilizes LED sources, with a combination of lay-in troffers, recessed can lights, and specialized track and display lighting utilizing directional heads and pendants. Exterior canopy and façade lighting uses well controlled LED optical systems for control of lighting within the tight property lines while maintaining appealing entries and highlighting the artwork around the entry. Interior theatrical lighting uses LED fixtures to greatly reduce the electrical and associated cooling loads within the Ceremonial hall.
Lighting controls involve motion sensing type devices, either occupancy or vacancy sensors in smaller rooms, theatrical lighting system and multi-zoned display. Some areas with more complex illumination elements will involve low voltage control stations and motion sensing devices. Rooms with good exposure to natural light will incorporate daylight sensing and dimming control. Security surveillance system is Ethernet based, utilizing the network system. The server will collect video streams and images as specifically programmed for each camera. The programming will allow for continuous streaming, scheduled periodic image collection, and image collection or streaming with motion sensing.
Clan House at Sealaska Heritage Institute has LED back lit glass panel. Lighting of the Glass Panel is designed and configured by HAI employee Ms. Nimmy Philips and the wood work behind the glass panel was constructed and designed with the Carpentry skills of HAI employee Mr. Robert Jensen.
