Cost Energy Effectiveness : To minimize the building footprint, while fitting it to the existing surface structures, angled walls, internal ramps and multi-level elevations are introduced to the design, easily handled by NRB’s structural steel shop. Phase 1 Operations has 2 shop areas requiring 14’ clear ceilings, while the balance requires only 8 or 9’. To achieve this height, specially engineered roof hats were designed to fit over open lower sections. In the “Dry”, 20’ ceilings to hoist locker baskets up for drying clothes were achieved by splitting the building vertically and horizontally for shipment, while heavy design loads were necessary for boilers/recovery units in the mechanical room above the locker areas. Amid Phase 2 and 3, is the atrium/hallway created in a similar way to the “Dry”, with a 10’ high clerestory placed over the top floor opening it up to 30’. The key to the precision fit & faster site finish of all these variations was NRB’s unique process of building it all together at the plant.

Technical Innovation : Building envelope is insulated w/ R31 rigid Polyiso on the roof and R22 spray foam in the vertical and horizontal wall “Z” bars, completely sealing cavities, crevices and eliminating thermal bridging. Windows are high performance in thermally broken aluminum frames with warm edged spacers and Low E argon filled sealed glass units. Lighting is sensor controlled and the roof is a white TPO for solar reflectivity. A hydronic heating system with condensing boilers and recovery system is used. The building has an area for 450 lockers, showers and “Dry”, a large area with 20’ ceilings and locker baskets hoisting miner’s wet clothing to the ceiling where large blowers dry them. A heat recovery ventilator is added to the clothes drying exhaust, and heat is recovered from hot water drains. Building energy modeling done proves annual energy will be reduced by 62%, and annual greenhouse gas emissions will be reduced by at least 860 tons. Payback on capital investment of equipment is 3.6 years.
Total Square Feet : 60000
Architectural Excellence : The multi-use design is detailed in 3 phases by a team of all stakeholders, including LEED. The unique multi-angled configuration with varying elevations, meet critical program/relational requirements achieving best use of horizontal and vertical space. Phases 1 & 2 endure heavy shift workforce travel to/from the connected head frame. Phase 1 has painted metal ceilings, concrete floors/non-slip ceramics and abuse resistant painted drywall; Phase 2 has easy clean ceramic tile walls and floors over the shower/bathrooms and 20’ high open “Dry” area where locker baskets hoist wet miner’s clothes up to dry. Phase 3, two-story Admin area, links by a wide 30’ high clerestory atrium hall with two-story glazed curtain wall at each end and a polished concrete floor. Carpet, painted drywall, glass walls & railings are also featured. Phase 1/2 exterior is heavy gauge steel to match existing structures. Phase 3 has unique angled ACM panels, emulating a jagged “rock face” prevalent in the area.
