Design Intent: One of the key issues that this site presents is the limited space for park-ing, as well as the set backs created by the adjacent buildings. The proposed designincreases the amount of site square footage available for parking and traffic circulation,by elevating the north and west ends of the building off of the ground. This intern, createsa nice entrance lobby, as well as more square feet (west end) due to the 43 setback.

Building Elements : The proposed design is a 7 story, steelframed building that provides a building footprint of only 3405 sfcompared to the actual 31085 livable sf.

Cladding: The building has a combination of light-weight steelpanels and curtain wall glass. The cladding is arranged so thatthe east and west facades of the building have a less glass withhigher R values. This reduced the energy costs significantly.

Service Core: The proposed core location was based on severalfactors including: centrality to the main entrance and the need forstructural support of the north wing of the building. The coresplacement allows direct access to all levels of the the building.

Parking: By decreasing the amount of square feet used for thebuildings footprint, more parking space becomes available. Forthe 31000 sf blding, 94 parking spaces will be needed.

Energy Analysis Summary: Theintial energy cost of a 15 yearperiod will be $498 k. The costcan be seen in the bar graph bymonth. The summer monthsrequire alot of cooling costs andduring the winter months anaverage heating cost. The cost ofenergy went down when Iremoved the glass curtain walls

on the east and west side, but Idecided that this was not afeasible answer to reducing theoverall cost.

Monthly Energy Consumption:Between May and Septemberare the greatest amount ofcooling costs. This could bereduced with less area on theeast and west facing facades.During the winter months, Octthrough Feb, the heating costsare much larger than the overallcooling costs. This could because by the elevated wings ofthe proposed building.

Annual Energy Consumption: Asseen in the graphs, the majorityof the cost come from spacecooling, area lighting, ventilationfans, space heating and waterheating. I was able to have thesenumbers increase and decreaseaccording to how much glasscladding I applied to the facadesand how much surface area wasexposed to the east and westdirections.

Design Intent: One of the major issues of this project is the large space needed on anextremely small site. In this design proposal, I tri ed to tackle this problem by going vertical.I also wanted to place a garden/patio area 5 floors up to create a unique restuarant environ-ment for this area. There is also a relatively large area left f or parking spaces and landscap-ing.

Energy Analysis Summary:The initial energy cost of a 15 yearperiod will be $499K which is not thebest of the three, but relatively close.The more tinted the windows werethe better. The position of the north-ern shaft core helps lower the cost aswell.

Energy Analysis Monthly Summary:Because of the relatively equalamount of hot and cold weather inLubbock, the placement of galzingthrough out the building had littleeffect on the energy costs.

Energy Analysis Annual Summary:The moajority of the energy goes tocooling. The second greatest cost islighting. These numbers variedbased on the location and orientationof the glazing on the building.

Site Circulation

Building Elements: The proposed design is a 10 story concrete framedbuilding. The footprintof the building i s 4025 sf. The total livable spaceis 29313 sf. This is not the ideal foot print for t his site.

Cladding: The building is composed of stone and glass. The claddingis arranged so that the east and west facades have a minimul amountof glass. This is the orientation that created the most efficient building.

Service Core: In this building there is two service cores for conve-nience and speed of circulation throughout the building. The place-ment also helps block some of the intense west sun light.

Parking: Due to the footprint of the building this is not the best choiceof the three for parking

DESIGN ANALYSIS [3] Building Elements: This proposed design is a 11, story steel frame buconcentration on the amount of green space created. The shifting of creates outdoor space to help minimize the carbon footprint created Cladding: The main cladding of the building consists of light weight recycl

panels and a curtain wall system who's glass has a high r value. The arracladding is to defer away from the typical Lubbock building which a blockService Core: The core is located in the far south east corner of the buildinallows for security to and from the core and service entrances away from thThe core does not become the main structural element of the building, whegrid is the focus.

Parking: There will be a required amount of 91 parking spaces. ThOn open space will allow for more parking on the ground level. If nWill be accessible underground, connecting to the core.

Building Footprint

Possible Parking

Design Intent: One of our main group concerns for our site was parking. This design is an attempt to minimizethe building footprint and allow for some on site parking. Another concern with the site is the lack of green spacein downtown Lubbock. Through this design, we tried to reduce the buildings carbon footprint and add somesustainable features to the building.

Energy Analysis Summary:The energy cost of a 15 year period will be

$432,000. This cost is reflected in the bargraph to the right. The months of June, July,and August will require mazimum coolingcosts and during the cooler moths the buildingwill require an average hearting cost. The costof the required energy reduced when Iremoved the amount of curtain walls orcovered glass with a perforated panel system.The initial savings by implementing thesechanges did not produce enough savings forthe bulding through energy cost or buildingsupplies to make the changes feasible.

Monthly Energy Consumption:Since weather is extreme in both the winterand summer months in Lubbock, the costsresults are much higher. One way to cut costto the owener is to install some sustainablefeatures like solar panels or using new tech-nolgy to capture wind energy. Another optionfor the building owner is to make sure allmechanical equipment is Energy Star rated.

Annual Energy Consumption:Represented by the pie charts, we can see themost demanding costs are space cooling andwater heating. I was unable to alter theamount demanded by these two buildingrequirements enough to alter the make p ofthe building. The obvious answer to the spacecooling dilema would be to line the amont ofcurtain walls on the facade

Analysis

-Structural System & Construction Type

In our design proposal we used a Rigid Frame steel structure with an irregular grid pattern. The Building utilizes post and beam type

construction.The the floors are constructed of composite steel deck slabs that have no greater spans than 15 feet. The approximate depth of the

slabs is 8-12 inches.

Piloti be attached to individual base plates on the roof slab of the third floor.

-Estimated Size of Members

The size of the members that we used are 17 x 13 columns and 8 deep beams. We found that the 17 x 13 columns werethe average sized columns for a building of similar comparison. The 8 deep beams are plausible because of the relatively short

spans, 15 and 126. Although for the drive through area a 26 deep beam was needed for the 43 span.

-Fire Resistance Strategy

Fire Escapes: 2 located on 1st floor - The main entrance and one located by the core. Fire stairs are both smoke proof an has two hourwalls and 1 hour doors.

Fire Extinguishers - Drystand Pipes will be installed with in the fire stair to be accessed by the fire department. Each floor will be

equipped with a sprinkler system.All structural members will be equipped with a fire rating of two hours.

Building MEP Analysis

-Zoning Design DecisionsWe have uniform zoning throughout the whole building except for the second and third floors because of the side piloti building. Thosetwo floors though are zoned the same.

-Heating and Cooling SystemsIn this design we are using a VAV heating and cooling system. We chose this because it allows a high degree of local temperature

control at a moderate cost. It is economical to operate and virtualually self-balancing. It is also the most versitile and widely used systemin large buildings.

-Configuration and Size of Major Equipment SpacesWe have 2250 sq.ft of major equipment space located in the basement of the building.

-Size of Members and ComponentsThe size of the ductwork members is 1 x 1. The size of the VAV control box is 18 inches because the square footage of each floor islarger than 1500 sq.ft.
