UBER MB 1 & 2 – LEED PLATINUM / WELL GOLD MI SS ION BAY HEADQUARTERS

San F ranc isco, CA

AlfaTech is currently involved in Uber’s innovative new San Francisco headquarters which is a new 420,000 square-foot, ground up office building in the Mission Bay district. We provided design/bid/build style Mechanical, Electrical, and Plumbing (MEP) engineering, lighting design, and Technology (low voltage, security, audio/visual) services, throughout the entire project. AlfaTech is part of the construction administration effort and served as the engineer-of-record for mechanical and electrical installations. We assisted the architectural design team with optimizing performance by assessing various utility, façade and wind studies. Life-cycle cost analysis, energy benchmarking, and computational fluid dynamics were critical tools to inform the design effort. The project is designed as an innovative, ultra-high performance building that focuses on an occupant-centric workplace and includes an elaborate IT infrastructure, a façade that responds to programmatic needs, an under floor air distribution system, a two-building atria system incorporating natural ventilation, and a central treatment system for collecting graywater and rainwater. The interactions between the occupants, the buildings, and the ambient, were at the heart of the architectural and engineering systems; targeting lower environmental metrics of 1,100,000 kWh in reduced energy use and 2,100,000 gallons in reduced water use.

• High-performance LED lighting with an occupancy driven network-based lighting control • Fuel cells redundantly powering building network operations • Solar domestic hot water system • PV-ready electrical system • Integrated building management system, including Smart Building Technology

• Significant reduction of building energy by means of combined hydronic chill beam and underfloor air system (UFAD) • Aggressive rainwater capture and retention. • Graywater reuse • Natural ventilation for main atrium social areas, creating a pleasant, open experience for employees and visitors. • Maximize use of day lighting to optimize workspace quality.

CASE STUDY:

LUCAS MUSEUM OF NARRATIVE ART Los Ange les, CA

The Lucas Museum was conceived with the bold ambition to challenge the way our societies appreciate art museums. Inspired by its resolute mission, the engineering design blasted off with the vision to deliver a lasting, centenarian building in harmony with its site. The carbon zero design harnessed heat and cooling from the soil beneath the museum with over 700 vertical bores. This constituted the deepearth, pulsating aorta of the geothermal field. A second element of nature was introduced by way of a thermally active water pond, which increased the site’s innate cooling capacity. These features were modulated by the high-efficiency, heat recovery central plant that provided all-electric, simultaneous heating and cooling (and no gas-fired boilers). Environmental quality for prime spaces – galleries, state of the art theaters, and lobbies – were controlled with underfloor air-distribution and radiant floors. Smart controls gently nudged temperature and ventilation parameters to adjust to visitors’ comfort. The superstructure lifted off with an exterior façade that self-shaded the thermal shell, effectively reducing cooling demand. Curved onyxglass organically traced the rooftop which formed the solar PV field. At 365 kW capacity, the renewable energy source reduced an estimated 10-15% of the electricity demand and swung the carbon footprint negative. Ahead of its time, the Lucas Museum will open the doors as an eco-friendly, ‘net zero energy’-ready museum that gives back to the surrounding community.

• Geothermal loop • A solar energy system • Natural ventilation • Displacement system • LED lighting • Spectrally selective glazing

& Relevant Projects

“A data center is the nerve center of a company…it embodies the most critical systems which are absolutely vital to the continuity of daily operations…”

D ATA C E N T E R P H I L O S O P H Y

DATA CENTER PHILOSOPHY

With the seemingly exponential explosion of data and the associated requirements for servers and storage, it isn’t surprising that many organizations, both public and private, are struggling to keep up with the ever-changing technologies and the immediate and constantly increasing requirements of IT and Facilities departments. AlfaTech has been on the frontlines of this trend for the past twenty years and has been a leader in the design and construction of state-of-the-art data center facilities. We implement the latest design methods for our clients to support emerging technologies and to assure energy efficiency and scalability for growth and changes in technology. We’ve made a corporate commitment to providing training and continuing education to a growing staff of engineers and project managers dedicated to the design and construction of data center facilities. Our esteemed team of professionals are educated in all areas of IT and Facilities operations and sustainable design for mission critical data center facilities, and are active members of the AFCOM, ASHRAE, The Green Grid, OpenCompute, 7x24 Exchange, SVLG and the USGBC. This commitment to continuous learning encourages growth and innovation to assure that our facilities are designed with the latest technologies, best practices, operational efficiencies and total cost of ownership in mind. Many members of our data center team were formerly employees in charge of IT and Facilities departments of large corporations, giving them a unique and practical perspective from which to interface with our client's management team, technical staff and end-users. These critical staff members are integral in bridging the gap between the facilities staff, IT staff and the executive leadership; bringing a common language and voice to all parties so each group is critical in assuring a successful program and implementing a solution that satisfies the current and future needs of the IT staff while providing clear and practical cost evaluations and controls to satisfy the fiscal constraints of the executive staff. Our firm’s commitment to designing cutting-edge data center facilities begins with a meeting-of-the-minds and is carried through the project’s completion and commissioning of the facility to assure everything is performing as intended and the facility meets or exceeds the design intent of the stakeholders. This is our Data Center Commitment and our commitment to our clients.

DATA CENTER STRATEGY

Developing a Data Center Strategy is not about planning or designing a specific data center facility, rather it is about developing an understanding of why the Data Center(s) exist in the first place. Companies who experience rapid growth or those that have been in business for many years often find themselves with a fragmented data center portfolio. This can include multiple server rooms, labs housing production systems, multiple colocation facilities, etc. All of these locations were likely established to accommodate growing demands for data center capacity. Most companies with established data centers lack a formal strategy that defines how to provide the business with the agility it requires to enable growth while maintaining a cost-effective data center footprint. The development of true Data Center Strategy begins with executive sponsorship. Our process is intended to work with key stakeholders to establish meaningful priorities, goals and objectives that align with the business plan and strategy. Having a strategy in place provides objectivity when making value driven decisions. An effective strategy will leverage strengths and encourage collaboration across the company. One key goal of the Data Center Strategy development process is to establish common ground between all stakeholders by using a common language everyone understands. This process draws attention to the business needs and strategies rather than departmental or even individual preferences. The results of an effective strategy will optimize OPEX and CAPEX by minimizing non-performing assets and establish buy-in from the onset of future Data Center initiatives.

DATA CENTER PROGRAMMING

Data center programming is fundamental in understanding the true business requirements and ensuring the design, and ultimately the construction, meets the business and end-user needs. AlfaTech has developed an extensive data center programming process and methodology that combines IT and Facilities requirements and objectives into a collaborative approach. The programming process consists of individual and/or group interviews, collaboration workshop combined with industry best practices. The programming effort produces a formal Owner Program Requirements (OPR) document that is then used throughout the design and construction process to maintain alignment with the defined business objectives and requirements. The OPR Development Process is intended to facilitate collaboration between stakeholders and bridge Facilities and IT organizations by aligning individual departmental objectives with overarching business requirements and strategies. An effective OPR is organized into the following sections: Business Requirements – Defines how the data center will support and or enable the business to meet the goals and objectives for the enterprise, focus on applications, service levels and business impact. Functional Requirements – Based on business requirements, defines the capacity, reliability, efficiency, scalability and modularity required to meet business needs.

Technical Requirements – Focused on IT, defines the requirements that drive plans for network, servers and storage that will ultimately be supported. Strategies around these technologies have significant impacts on design considerations.

Operational Requirements – Focus on Facilities and Operations. Defines support strategies, physical security, maintenance and operational requirements for a successful facility.

Design Considerations – Based on all of the above, the design considerations serve as instructions to the design team to point them in the right direction. This section includes all required design disciplines. While AlfaTech has the capability and experience to take clients from concept to move-in, we believe the most important step in this process is initial programming. This is where the true business requirements are defined and put into proper perspective regarding competing priorities such as budget, schedule or location. The programming process guides our clients through all necessary considerations to effectively define data center needs and capabilities. This is often measured with parameters such as size, capacity, reliability, efficiency, scalability and sustainability. The process we have developed combines years of both Facilities and IT experience into an effective Data Center planning methodology.

D ATA C E N T E R P H I L O S O P H Y

DATA CENTER DESIGN PHILOSOPHY

Location : The philosophy of design must take into account local weather and atmospheric conditions as well as utilities. Weather conditions of extreme cold or hot ambient temperatures, humidity and other considerations such as high atmospheric dust content in farming communities will need to be accounted for in the design. Utilities data such as power capacity, reliability and cost; and similar information for data fiber, fuel oil, water … etc. Local building codes may have a large impact on the types of HVAC systems allowed (efficiency), Power generator operational hours and pollution control, sound level and structural design requirements. Redundancy : The philosophy of redundancy must be based on and satisfy the operating philosophy of the data center company. Therefore, if the data center operating philosophy is to mirror all data between two distant sites, the loss of power, a large earthquake or other such events, would require the operation be run from a second site. This condition would require a lesser level of redundancy than an independent site requiring all redundancy be located on site which requires consideration for equipment redundancy when a generator or other major piece of equipment is down for maintenance.

Space Allocation : Each data center operator/owner will have a desired operational layout concept that must be incorporated into the Basis of Design for a given property providing building flexibility, along with local code requirements, building owner requirements, city requirements, and needs of any co-inhabitants in the building. This might include separation of batteries into dedicated rooms, EMF considerations , rack/row lengths, racks or cabinets to house servers, floor and roof seismic loading limits, raised floor height considerations, security concept, equipment access to data floor, generator and equipment yard sighting on a given lot, or other requirements. It is interesting that some clients are moving away from using raised floors. The overall concept of the data center usually starts with definition of operator philosophy on wire management such as data routes and power routes above or below raised floor or split; type of power distribution and power usage of a typical server rack. Power Systems : The philosophy of design for the data center power systems is either a radial or a distributed distribution system. Radial systems are used less frequently and typically on smaller facilities of less than 4000 amps because of the high cost and size of equipment above 4000 amps. Distributed distribution systems provide the opportunity to disperse power and keep equipment under 3000 amps and generator sets to a maximum size of 2 megawatts. The distributed distribution system is more reliable since a single point of failure will not necessarily bring down an entire system. A distributed system must be properly designed to include UPS loads, and HVAC loads to generator ability to start these loads. HVAC loads must be evenly spread across the distributed power busses to balance loads and ensure that all HVAC units serving an area are not taken off line when one bus goes down. Owner preference may be for use of PDUs or individual transformers and panels to distribute power to power strips on individual racks. Monitoring and power management can be done at rack level or 480 volt level with significant cost variation.

D ATA C E N T E R P H I L O S O P H Y

Temperature Control : The philosophy of controlling temperature in the data center has been driven by data center operator concerns and desires to manage this function. A sophisticated operator may desire zone temperature control based on loading of given areas of the data floor; this may include modulation of air volume (savings on fan power usage) and or modulation of air temperature, but usually not both because of control cost. Some of our clients desire a design using hot and cold aisles between alternating rows of server racks; however this brings the problem of short circuiting of hot air into cold aisles on ends and at top of racks. If server cabinets are used, the specifics of the cabinets will effect the air delivery method and temperature control selected. The need for redundancy and reliability has led many data center operators to utilize PLC based controls over DDC based controls. AlfaTech has extensive experience providing detailed design of both systems types. Humidity Control : The philosophy of humidity control in the data center is driven by two parameters: range of operation and speed of control response. Range is usually between a low of 25% to 35% RH and a high between 65% and 80% RH; the lower the low, and higher the high, the easier the control and less expensive the operation. Speed of response will dictate the type of system required, the faster the control, the higher the cost, and the more energy used. Fast response is normally not a factor unless the user is unaware of the implications; servers do not care what the humidity is as long as it is below 80% to reduce corrosion and above 25% to reduce static charge potential for dissipation.

Fire Protection : Is the client standard a VESDA detection system? Does the client desire an FM-200 system as a standard? It is assumed that a zoned preaction dry pipe distribution system will be used to feed fire sprinkler heads. Fuel Oil : Design philosophy is based on rate of use, timing for deliveries, and length of time the data center must remain functional. Other design considerations are actual capacity that can be extracted from tankage, fuel filtration requirements, and redundancy of fuel delivery system to generators. Calculations and Diagrams: Alfa Tech’s design philosophy is to diagram systems for purpose of discussion and to provide options to allow the owner to make educated decisions on systems they want implemented in their data center facility. Initial calculation spreadsheets are set up to allow us to easily modify inputs to perform what-if system variations. During this phase of development, we like to identify cost and schedule implications to eliminate non-feasible solutions. AlfaTech is experienced in data center commissioning and understands the problems to include sequencing to failure and assuring system design allows this failure to occur. Maintenance : One of the key elements in designing a data center is the ability to allow maintenance of equipment to take place without effecting operating systems. Maintenance can be very difficult in a minimally designed system, therefore install dollars must be expended to ensure the ability to take equipment off line.

HVAC Systems : The philosophy of design for the data center cooling systems is primarily dependent on three things: local codes; the physical restraints and opportunities of the facilities such as ability to place equipment in exterior yard or on roof; and the preferences of the data center operator. AlfaTech designs have included: on floor CRAC units with DX cooling in yards and on roofs; CRAC units with chilled water cooling using both air cooled chillers and dry coolers located in yards and on roofs; rooftop air cooled package air handling units serving air through duct down to under floor; interior mezzanine located air handlers with ducted air down to floor; rooftop air cooled chillers to provide cooling; and floor mounted built up air handlers supplying air under floor. The ideal power efficient system will incorporate air side economizers to use free cooling and/or wet side economizers such as dry coolers. Wet towers and other evaporative based cooling solutions are a problem due to the necessity of storing large quantities of water. If a large source of water is available, such as a lake or ground water wells, this is a plausible option. Air discharge pattern to underfloor or into cabinets can present design problems if improperly implemented, as the venturi effect can pull air from the data room back under the raised floor.
