Site Inventory / Analysis There are some environmental concerns surrounding our site choice. The flood plane is not far from Folsom and in an extreme case we could have to deal with that flood water. There are also seismic concerns in this area which will affect the material choices and building construction.

Site Inventory / Analysis
The Pacific Gas and Electric building housing telephone lines does not provide a pleasant view.
Buildings in the general surroundings range from 2-10 stories in height. This will take some consideration to not shadow them completely when building a 35 story building.
An unfortunate dead patch of vegetation offers an opportunity to liven up the space with a bit of green.

Context Model Documentation The Transbay Downtown Residential District, which is wholly within the Transbay Redevelopment Project Area, comprises mostly publicly owned parcels containing infrastructure or underutilized land related to the Transbay Terminal and former Embarcadero Freeway. This district generally extends along the north side of Folsom Street from Spear to Essex Streets, and between Main and Beale Streets to the north side of Howard Street. Laid out in the Transbay Redevelopment Plan and its companion documents, including the Design for the Development and the Development Controls and Design Guidelines for the Transbay Redevelopment Project, is the comprehensive vision for this underutilized area as a high-density, predominantly residential, district within walking distance of the downtown core, transit facilities, and the waterfront. The plan for the district includes: a mix of widely-spaced high-rises, mixed with a street-defining base of low- and mid-rise buildings with ground floor townhouses; a public open space on part of the block bounded by Folsom, Beale, Howard, and Main Streets; ground-floor retail along Folsom Street; and several new alleyways to break up the size of the blocks.

History of San Francisco
The area that was once known as Yerba Buena and part of Mexico, began to attract American settlers and was claimed as part of America during the Mexican-American war in 1846. It was then renamed San Francisco but remained a small settlement because of the geography. The population boom in 1848 was thanks mostly to the California Gold Rush and later Silver discoveries. The famous cable cars started in 1873 and as the population kept growing, it earned the title of 8th largest city in the US around 1890. It was known for itâ&#x20AC;&#x2122;s art scene as well as its flamboyant styles and large houses. In 1906 a large earthquake struck San Francisco and ruptured many gas lines that set a fire that would burn through the city for several days. The fire destroyed 3/4 of the city including most of downtown. More than half the cityâ&#x20AC;&#x2122;s population was left homeless and settled in tents in Golden Gate Park. The rebuild was quick and the majority in the Beaux Arts style. In the Great Depression San Francisco held steady and constructed the Golden Gate Bridge and the Bay Bridge. Around this same time Alcatraz became the maximum security prison it is known for today. Freeways began going up in the 50s and 60s and the city began to lose industrial jobs leading to a decrease in the population. A large influx of writers inhabited the North Beach area, Hippies to Haight-Ashbury, and in the 70s the city became a gay rights hub. Another earthquake reeked havoc 1989, damaging much in the South of Market and Marina districts as well as the Embarcadero and Central freeways. In the late 90s there was a boom of entrepreneurs leading to record high populations in the 2000s leading to a wave of high-rise development. The Transbay terminal redesign has led to a revitalization of the SOMA region and continued high-rise development.

History of Tall Building There were two developments in the 19th century that paved the way for high rise buildings. The first was the safer elevator with the safety feature to not allow you to plummet to the bottom of the shaft if one of the cable broke and a motor to make it a more practical option. The second was the steel beam and column construction that allowed buildings to be constructed taller and more resistant to the forces. Some of the modern materials used aside from steel are concrete because of its versatility and glass to let the light in. Some of the early skyscrapers were the Metropolitan Life Insurance Tower, the Woolworth Building, Bank of Manhattan, Chrysler Building, Empire State Building, World Trade Center, the Sears Tower, Petronia Tower, Taipei 101, and the Burj Khalifa.
22
Design Vertical Communities There has been a lot of research in the area of vertical communities and ways to better them in recent years. The idea of building up has been around for a long time but modern ideas are focusing more on an entire community in an upward form. The idea of having each floor represent a block that are stacked upon each other creating smaller neighborhoods that come together to create a larger â&#x20AC;&#x153;cityâ&#x20AC;? that contains all you may need. When space to build is becoming scarcer, it is important to investigate other options. The environmental benefits to vertical communities is immense. Most of these communities are being designed in a sustainable manner and with an entire neighborhood stacked on a smaller parcel of land, it leaves more area to be taken advantage of by the environment. These buildings usually contain a large number of residential units, some green spaces, and a generous amount of multi-use capacity.

Building Codes / Life Safety / Security
This bulletin is designed to standardize the San Francisco Fire Department’s requirements for annunciation panels in high-rise buildings. It is the Bureau’s policy to require that all alarm initiating devices (including water-flow alarms), be annunciated in the Fire Command Center (FCC) by means of a visual display which indicates the type of device by building floor, zone, or other approved designation from which the signal originated. Audible indication at the panel is required for supervisory and trouble signals. Additionally, visible annunciation shall be provided to indicate the status of emergency equipment that may affect building occupants in a fire situation, i.e. emergency generator, fire pump, etc. Other fire protection systems in the building, such as FM 200, Inergen, Ansul, etc. Shall also be annunciated visibly and shall sound the alarm in the appropriate areas. A red LED (light emitting diode) type of visual display is required for all alarm initiating devices. An indicator light is required for each type of initiating device present on each floor. Manual pull stations, area smoke detectors, duct detectors, elevator lobby and machine room smoke detectors, heat detectors, auxiliary alarms, and sprinkler water-flow must be indicated separately. The following items must also be indicated on the LED panel: 1. Fire Pump: a) Running: green lamp b) Trouble: yellow lamp c) Phase reversal (electric): yellow lamp d) Low fuel (diesel): yellow lamp
2. Emergency Generator: a) Running: green lamp b) Trouble: yellow lamp c) Low fuel: yellow lamp 3. Secondary Water Supply: a) Low water level: yellow lamp b) High water level: yellow lamp

Building applications must also meet LEED standards for the use of on-site renewable energy or the purchase of renewable energy credits
The new provisions address many areas relating to design, construction, and emergency egress from tall buildings, such as increasing structural resilience to building collapse from fire and incidents, requiring a third stairway for tall buildings, increasing width of all stairways by 50 percent in new high-rises, calling for luminous markings delineating exit paths in buildings more than 75-feet tall to facilitate rapid egress and full building evacuation, and a host of other recommendations relating to construction and emergency response.

Case Study Bank of China Tower, Hong Kong Bank of China (BOC) Tower is located at No.1, Garden Road, a flourishing center of activity in Hong Kong’s business and financial core. The tower structure of 315 meters and two masts of 50 odd meters give the building its aspiring height of 367.4 meters – which, in 1989, made it the tallest in Hong Kong as well as the fifth by height in the world. The BOC Tower is a masterpiece of the world-renowned Chinese-American architect I.M. Pei. His inspiration for the building’s construction was the elegant stature of bamboo, its sectioned trunk reaching higher and higher with each new growth.

Case Study Millennium Tower, San Francisco This 58 story building offers multiple sizes and styles of dwelling units. From the penthouse with 2706 square feet to a smaller more affordable 773 square feet this high rise offers 3 types of units- the residences, the city residences and the grand residences. The building is home to a 20000 sq. ft. ownerâ&#x20AC;&#x2122;s club level with a pool, wine tasting room, terrace, fitness club, and children room. The ground floor houses a contemporary French restaurant. Leasing these ranges from $4000-$20000 per month and they can be purchased for $600000-$5 million. This building has thrived because of its location in the Bay area.

Design Intention & Goals
Intention:
To create a multi-use high rise building that will fulfill many of the necessary functions of the area. Right now, the site is serving as a storage unit for the Trans bay Redevelopment and following that the area will be open and unused. There is significant traffic surrounding the area from a large highway as well as a bike route that travels on Folsom. Because of the traffic the first couple floors will be used to house an assortment of retail stores. There are not many stores in the immediate area and the added retail will provide easier access to those in the vicinity. There will be a few floors of office area providing opportunity for businesses to operate in the Trans bay region. Because of the siteâ&#x20AC;&#x2122;s location near many popular tourist spots there will also be hotel floors included to house travelers in part of town that is being rejuvenated by the redevelopment. The majority of the building will be used for residential housing, something that is needed in the south of market area. In addition to providing the necessary functions of the area we will incorporate modern technology and design to create a building that will integrate well in its surroundings and explore the future of sustainability. There is no limit on the cost of the building. The materials used will need to be strong and stiff enough to support the ultimate height of the design and giving enough to allow the integration of natural light and ventilation. The building will not exceed 12,500 square feet per floor nor 40 floors.
Goals:
Design a building That can be integrated into its surroundings That will be LEED certified That will include as many sustainable and green technologies that are possible That has a human scaled feeling That will fulfill a multitude of functions efficiently That will be constructed in a fiscally responsible material and design That will following the building, fire, and other codes of the city of San Francisco and the state of California That is unique to its site, designers, and city of San Francisco

Sustainable Strategy Material Many of the earlier tall buildings were over designed and did not make to most efficient use of the structural materials that they were using. Tubular systems have begun being used more which helps but looking into the rigid systems, they seem to have the most efficient outcome for the least amount of material, that is after you select the right geometric configuration. It is also important to select the material with the right stiffness, this can also help to cut down on materials.
34
Sustainable Strategy Reducing Energy Use
Through Design-It is important to design with the environment in mind. Since San Francisco does not vary much in the temperatures experienced, we can study the peak times to use the environment for heating and cooling and have a ventilation system set up to accomplish that. We also plan to design to allow nearly every space access to natural light. Double skin facades could be considered due to their helpful wind buffering on the top floors allowing you to still use the natural environment for circulation. Displacement Ventilation Light Shelves
Generating Energy Through Wind-Because San Francisco is surrounded by water on three sides there is a possibility of significant energy collection via wind. Creating a wind farm incorporating the upper floors of a tall building can significantly decrease energy needed from the grid. This is being incorporated is many tall building around the world including one significant example proposed on a lake front building in Chicago. Through Sunlight-Photovoltaic Panels are another great way to collect free energy on tall buildings. By placing them in areas that receive a large amount of sun throughout the day, you can collect a sizeable amount of energy to help run the building on. There are some concerns with this method, however. It is key to note where the building is receiving the maximum sunlight throughout the day. This will change as the sun path changes throughout the year and it is crucial to place these panels where their maximum potential will be recognized. There have been recent developments of pv technology, including glass that can be used throughout the entire building facade. They have also developed colored solar panels that can be integrated to give more choices on how this building could look.

LEED Platinum Checklist Energy and Atmosphere Prerequisite 1: Fundamental Commissioning of Building Energy Systems Required Intent: To verify that the project’s energy-related systems are installed, and calibrated to perform according to the owner’s project requirements, basis of design and construction documents. Benefits of commissioning include reduced energy use, lower operating costs, fewer contractor callbacks, better building documentation, improved occupant productivity and verification that the systems perform in accordance with the owner’s project requirements. Requirements The following commissioning process activities must be completed by the project team: Designate an individual as the commissioning authority (CxA) to lead, review and oversee the completion of the commissioning process activities. The CxA must have documented commissioning authority experience in at least 2 building projects. The individual serving as the CxA must be independent of the project design and construction management, though the CxA may be an employee of any firm providing those services. The CxA may be a qualified employee or consultant of the owner. The CxA must report results, findings and recommendations directly to the owner. For projects smaller than 50,000 gross square feet (4,600 gross square meters), the CxA may be a qualified person on the design or construction team who has the required experience. Domestic hot water systems Renewable energy systems (e.g., wind, solar) The owner must document the owner’s project requirements. The design team must develop the basis of design. The CxA must review these documents for clarity and completeness. The owner and design team must be responsible for updates to their respective documents. Develop and incorporate commissioning requirements into the construction documents. Develop and implement a commissioning plan. Verify the installation and performance of the systems to be commissioned. Complete a summary commissioning report. Commissioned Systems Commissioning process activities must be completed for the following energy-related systems, at a minimum: Heating, ventilating, air conditioning and refrigeration (HVAC&R) systems (mechanical and passive) and associated controls Lighting and daylighting controls

LEED Platinum Checklist Prerequisite 2: Minimum Energy Performance Required Intent To establish the minimum level of energy efficiency for the proposed building and systems to reduce environmental and economic impacts associated with excessive energy use. Requirements OPTION 1. Demonstrate a 10% improvement in the proposed building performance rating for new buildings, or a 5% improvement in the proposed building performance rating for major renovations to existing buildings, compared with the baseline building performance rating. Prerequisite 3: Fundamental Refrigerant Management Required Intent: To reduce stratospheric ozone depletion. Requirements Zero use of chlorofluorocarbon (CFC)-based refrigerants in new base building heating, ventilating, air conditioning and refrigeration (HVAC&R) systems. When reusing existing base building HVAC equipment, complete a comprehensive CFC phase-out conversion prior to project completion. Phase-out plans extending beyond the project completion date will be considered on their merits. Existing small HVAC units (defined as containing less than 0.5 pounds [0.227 kg] of refrigerant) and other equipment, such as standard refrigerators, small water coolers and any other equipment that contains less than 0.5 pounds (0.227 kg) of refrigerant, are not considered part of the base building system and are not subject to the requirements of this prerequisite.

Energy and Atmosphere - Credit 1 15 Points
Intent To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use. Requirements Select 1 of the 3 compliance path options described below. Project teams documenting achievement using any of the 3 options are assumed to be in compliance with EA Prerequisite 2: Minimum Energy Performance. OPTION 1. Demonstrate a percentage improvement in the proposed building performance rating compared with the baseline building performance rating. Calculate the baseline building performance according to Appendix G of ANSI/ASHRAE/IESNA Standard 90.1-2007 (with errata but without addenda1) using a computer simulation model for the whole building project. Projects outside the U.S. may use a USGBC approved equivalent standard2. The minimum energy cost savings percentage for 15 points at 40% savings. For the purpose of this analysis, process energy is considered to include, but is not limited to, office and general miscellaneous equipment, computers, elevators and escalators, kitchen cooking and refrigeration, laundry washing and drying, lighting exempt from the lighting power allowance (e.g., lighting integral to medical equipment) and other (e.g., waterfall pumps). Regulated (non-process) energy includes lighting (e.g., for the interior, parking garage, surface parking, façade, or building grounds, etc. except as noted above), heating, ventilating, and air conditioning (HVAC) (e.g., for space heating, space cooling, fans, pumps, toilet exhaust, parking garage ventilation, kitchen hood exhaust, etc.), and ervice water heating for domestic or space heating purposes. For this credit, process loads must be identical for both the baseline building performance rating and the proposed building performance rating. However, project teams may follow the exceptional calculation method (ANSI/ASHRAE/IESNA Standard 90.12007 G2.5) or USGBC approved equivalent to document measures that reduce process loads. Documentation of process load energy savings must include a list of the assumptions made for both the base and proposed design, and theoretical or empirical information supporting these assumptions.

Energy and Atmosphere - Credit 2 5 Points
Intent: To encourage and recognize increasing levels of on-site renewable energy self-supply to reduce environmental and economic impacts associated with fossil fuel energy use. Requirements Use on-site renewable energy systems to offset building energy costs. Calculate project performance by expressing the energy produced by the renewable systems as a percentage of the building’s annual energy cost and use the table below to determine the number of points achieved. Use the building annual energy cost calculated in EA Credit 1: Optimize Energy Performance or the U.S. Department of Energy’s Commercial Buildings Energy Consumption Survey (CBECS) database to determine the estimated electricity use. The minimum renewable energy percentage for 5 points is 9% savings.

Energy and Atmosphere - Credit 4 2 Points
Intent: To reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct contributions to climate change. Requirements OPTION 2 Select refrigerants and heating, ventilation, air conditioning and refrigeration (HVAC&R) equipment that minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change. The base building HVAC&R equipment must comply with the formula, which sets a maximum threshold for the combined contributions to ozone depletion and global warming potential. Small HVAC units (defined as containing less than 0.5 pounds [0.227 kg] of refrigerant) and other equipment, such as standard refrigerators, small water coolers and any other cooling equipment that contains less than 0.5 pounds (0.227 kg) of refrigerant, are not considered part of the base building system and are not subject to the requirements of this credit. Do not operate or install fire suppression systems that contain ozone-depleting substances such as CFCs, hydrochlorofluorocarbons (HCFCs) or halons.
