Zones Service Core

North West View Zones Service Core

The design attempts to combine the program requirements in to two major spaces; a horizontal space which consists of the restaurant and retail space and a vertical one that encloses the rest of the program. The vertical Space is divided into two zones (north and South) to take advantage for natural lighting. The two major spaces are interconnected at ground level to create a uni�ed whole space.The energy challenge for this particular design is to reduce the cost of items such as cooling, heating, lighting and other energy consumption problems.The building is oriented towards the north. This gives an opportunity to use natural light to help reduce energy consumption. The building uses a curtain wall system on the north side of the building (the main access) to take advantage of the natural light. On the south side the amount of glazing is reduced to allow for the control of direct sun light.The core is designed as a double core placed on the east and west of the build-ing, multiple cores work well for low rise buildings. A double core placed in a building facing north has a low annual cooling load.

-The building is a small re�ection of the buildings close to the site. -The design demonstrates simplicity and easy understanding.-It is a 10 story structure with at least 12’ ft high on each �oor. A hole in the middle of the structure let the sunlight re�ect into the building. -The structure has a split core in which the vertical shafts stand against the south wall; each shaft locates in both east and west directions. -The cladding on the building is horizontal strips of concrete and glazing running from top to bottom along the building. -Each �oor has approximately 30% of glaz-ing which helps sun light to provide enough illumination for the working, and living activi-ties during the most part of the day.

Chosen Design :Preliminary Design 1

This proposal represents best what the intention of the design is and also works better energy wise and also more economic for the region of lub-bock, it helps to conserve more energy than the other two designs.

-The main idea in the proposal 3 was to get a more private view in every �oor, divide the whole square footage into what it would look like 5 diferent small buildings, by pulling volumes out and pushing others in, getting or alternating the volumes in the building, this would allow protection from the sun to the windows in the other stories, helping with the reduction in energy cost.-There were some variations in the model, different cladding, variationsin where the win-dows were positioned, but there was not a very drastic change in the energy consumption.-The different areas of the building are distributed in 7 �oors, and it helps to maxize space and area.-The building is oriented towards north, this helps to use better the light and help with the energy costs.The building is a steel frame, concrete and glass.

Structural system:We decided to use precast concrete for the structural system of our building. Precast concrete systems are characterized by reduced depths and de�ections for spanning members, faster construction and increased quality and durability.

Con�guration of Structural Systems:24” x 24” Precast Columns for heights of 24’ We are using these columns mainly for the �rst �oor of our building which includes the restaurant, lobby and the retail areas. 12” x 12” precast columns for heights of 12’ we are using these columns for the rest of the building since all the �oor distances are the same 12’.12” x 24” precast beams for spans of 30’ we decided to have spacing between columns of 30’, for this reason the use of this beams are apropiate. 9” thick precast solid topped slab for spans of 30’

Fire Resistance:The building needs to be sprinkled, with:a. Maximum travel distance of 300 ft.b. 100 Ft. Maximum common path of Egress travelc. 49 occupants max. in largest room or area that may have only one means of Egress.d. Minimum length of a dead end corridor of 50ft.S

ANALYSISBased on the occupancy level, we identi�ed three di�erent zones in our design:Zone One: the �rst �oor is is divided into two subzones; the restaurant and the lobby space.Zone Two: the o�ce space. Zone Three: the living space. vBased on the three di�erent zones, we choose a Multizone Heating and Cooling System. To be more speci�c we are using a Central Air System: Single Duct, Constant Air Volume (CAV).In the Multizone System, several ducts from a central fan serve several zones. This system blend hot and cold air at the fan to send air into each duct at the temperature requested byy the thermostat in that speci�c zone.

The major components for this MEP system are: a boiler and chimney, chilled water plant, cooling tower, fan room, outdoor fresh air and exhaust louvers, vertical supply and return ducts, supply di�users, and return grilles.

The sizing of the major equipment spaces such as the boiler and chiller room, fan room, electrical and commu-nication room and the water pump rooms are illustrated in �gure 1 with their correspondent sizes.The size of the duct work is 2’x1’ and the di�users are 1'-9" in diameter.
