SITE ANALYSIS

The front yard setback for structures and outdoor dining areas/patios shall be no less than the average setback established by the development on the adjacent lot or lots. On corner lots, the front setback shall be no less than zero (0) feet and no greater than the setback established by the development on the adjacent lot.

Landscaping Requirements:

No less than ninety (90) percent of the required front yard excluding paved curb returns or driveways up to a minimum of five (5) percent of the total development lot area shall be landscaped and permanently maintained, except that: a. Interior courtyards shall not be included in any required landscaping. b. Buildings with zero (0) front and side setback shall not be required to have any on-site landscaping except that when a structure with zero (0) setback has adjacent parking five (5) percent of that parking area must be landscaped.

The parkway areas of adjacent rights-of-way, excluding paved curb cuts and driveways shall be landscaped and permanently maintained. This shall be in addition to the landscaping required above. Any landscaping placed in the parkway must be in compliance with section 29-30(b)(6)i.3. of the zoning ordinance.

All required landscaping must be visible from the public right-of-way and placed for maximum enhancement of the property. Landscaping shall meet the requirements of section 29-3(62).

Zones

Service Core

-The building is a small reflection 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 floor. A hole in the middle of the structure let the sunlight reflect 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 floor has approximately 30% of glazing which helps sun light to provide enough illumination for the working, and living activities during the most part of the day.

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 unified 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 building, multiple cores work well for low rise buildings. A double core placed in a building facing north has a low annual cooling load.

PRELIMINARY DESIGN_

ANALYSIS

Preliminary design 1

-The main idea in the proposal 3 was to get a more private view in every floor, 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 windows were positioned, but there was not a very drastic change in the energy consumption.

-The different areas of the building are distributed in 7 floors, 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.

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 lubbock, it helps to conserve more energy than the other two designs.

Business B: Of_ces; 100 ft. per occupant Assembly A-2: Restaurant; 15 ft. per occupant Mercantile M: Retail or wholesale store; 60 ft. per occupant Residential R: Living space; 200 ft. per occupant

Structural system:

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

Configuration of Structural Systems: 24” x 24” Precast Columns for heights of 24’ We are using these columns mainly for the first floor 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 floor 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 travel c. 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.

ANALYSIS

Based on the occupancy level, we identified three different zones in our design: Zone One: the first floor is is divided into two subzones; the restaurant and the lobby space.

Zone Two: the office space.

Zone Three: the living space. v Based on the three different zones, we choose a Multizone Heating and Cooling System. To be more specific 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 specific 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 diffusers, and return grilles.

The sizing of the major equipment spaces such as the boiler and chiller room, fan room, electrical and communication room and the water pump rooms are illustrated in figure 1 with their correspondent sizes.

The size of the duct work is 2’x1’ and the diffusers are 1'-9" in diameter.

The plumbing wall is large enough to house the supplu, waste, and vent piping necessary to serve the fixtures.

Based on the occupant level which is 50 people, we need 2 restroom for men and 2 restroom for women. One accesible ADA fixture of each type is required to provide acces for disabled persons. In toilet rooms with partitioned water closet compartments, at elast one such compartment must be wheelchair accesible.
