Architecture:

This Hotel was designed to represent the surrounding town as well as make its occupants feel at home when they are away from home. To accomplish this goal it was given simple layout, a porte-cochère covering the entrance and exit which is over the driveway leading to the parking garage. It exhibits a large reception area with a Pavilion to welcome guests, most of the guest services are also on this level. The rest of the hotel possesses a standard layout to help guests easily find their way to and from their rooms.

Building façades

Exterior Façade is comprised generally of two types. Much of the lower façade uses a brick finish, while the upper portion uses an exterior insulation finishing system (EIFS).
The EIFS panels are attched to the light gauge stud walls using corrosion resistant fasteners, and are comprised of insulation, a reinforcing mesh, and several coats of waterproofing material.

A standard composition is shown below:

Roofing:

Fully adhered TPO white .060 membrane roofing system over
Tapered foam roof insulation (R-30 minimum) four inch minimum slope on
a vapor barrier supported by a
One hour rated, four or eight inch thick precast hollow core planks

Sustainability Features

Credits 4.1, 4.2:  Steel decking contains recycled content.

Construction:

The Mountian Hotel has not yet reached the construction phase.

Coldformed steel is to be designed constructed by the cold formed contractor.

Electrical:

The main power source for the Mountain Hotel is 208/120 volt 3 phase 4 wire conduit system. The calculated total demand is 1332KVA. There is a 350 KW diesel backup generator in the parking deck to run the emergency lights and fire pump in case of power failure.

Lighting:

The lighting for the Mountain Hotel is run off of 120V single phase. All of the guestroom spaces are lit using ceiling or wall mounted compact fluorescent lamps. The other interior spaces are lit with a combination of compact fluorescent, incandescent A-19, and T8 sources, all fluorescent lamps are 2700K with 1750 initial lumens. The bar has a light strip of color changing LED's.

Lighting in the pool area consists of ceiling and wall mounted LED and halogen lamps.

Exterior lighting is comprised of fluorescent, LED, HID, and metal halide lights.

Mechanical:

Heating ventilation and air conditioning in all parts of the Mountain Hotel is controlled using a combination three separate systems. One 25 ton rooftop air handling unit distributes 4,600 CFM of outside air to the guest rooms. Two 9 ton rooftop air handling units distribute a combined total of 3,000 CFM of outside air two the corridors and a single unit in the basement distributes 3,275 CFM of outside air to the remaining spaces. The rooftop units have a natural gas heating section and a compressor for cooling. The basement unit has and electric heating coil and is connected to a rooftop condenser.

The temperature is maintained in each space using a series of heat pumps. The guest rooms each have a 200 CFM through wall heat pump which is controlled by a thermostat on the opposite wall. The heat pumps for the interior spaces are separated into two parts. Each has its own coil on the roof which is connected to a coil inside. The heat pumps in the guest rooms have programmable occupied and unoccupied modes which close the intake and turn off the fans when set as unoccupied.

The third component of the system is the ventilation fans which evacuate the air from the bathrooms and the kitchen.

Structural:

The hotel rests on reinforced concrete spread footings ranging from 12 to 42 inches in depth. Concrete piers transfer the load into the interior footings from the steel columns. The exterior concrete basement walls rest on strip footings, ranging from 12 to 24 inches, are load bearing and double as sheer walls for the lateral system. A500 Grade B hollow structural steel ranging from four to 16 inches, longer dimension, is used for the superstructure columns. Some of the floors are supported by wide flange beams, ranging from W8 to W21, while others are resting on steel stud bearing walls.

The lateral system employs a combination of reinforced concrete shear walls, specially reinforced masonry shear walls and light framed wall system with flat strap bracing extending from the ground floor to roof level in both the long and short directions. Floors ground through six are installed as a series of eight inch precast hollow-core planks ranging in length from 9' 2” to 25' 8”. The roof is also built of four or eight inch hollow-core planks. Both the brick walls and EIFS system are attached to cold formed steel stud walls. The loading on the exterior facade is transferred through the wall framing to the floors and into the lateral system.

Fire Protection:

An automatic sprinkler system is utilized by the Mountain Hotel and complies with the 2000 IBC and NFPA-13,14,20, and 24. The sprinkler system is zone controlled on a floor by floor basis. A dry sprinkler is provided for the port cocher and a dry standpipe for the garage. The basement houses a 750GPM fire pump, and 7.5GPM jockey pump.

All walls are encased by fire resistant materials.

Each stairway contains a pressurization fan which creates 1000cfm per door.

Transportation:

The main entrance and lobby is on the second floor through the port cocher, the other floors are accessible from the lobby via two centrally located elevators. Stair towers at either end of the building allow access to all floors as well as providing two emergency exits.

Telecommunications:

The Mountain Hotel provides guests with a variety of digital services including telephone, high speed internet, and cable TV. Each is controlled by terminal boxes on the second and fifth floors from where it is distributed out to the rooms.
