WEATHER ANALYSIS

High Dry Bulb Occurrences

AlfaTech provides weather analysis to review historical weather data to influence site selection, for HVAC equipment sizing, and for other critical building arrangement decisions. American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) publish BIN, or analyzed “average” weather data, which is typically issued for airports and major metropolitan areas. ASHRAE also posts analyzed data for these sites such as extreme weather conditions that can be expected over a five-year period, a ten-year period, and on up to a fifty-year period. ASHRAE also publishes an Extreme Max Wet Bulb temperature which is important for design of any evaporative process such as cooling towers or evaporative cooling systems. The challenge with published data is that extreme weather conditions published by ASHRAE do not cover all cities and possible data center facility locations. Also, the extreme weather data represents the single worst-case conditions to be expected, but provides no information on how long that condition may last, or how often and how long weather conditions exist just below these extreme conditions. Through downloaded hour-by-hour weather data information, AlfaTech is able to provide additional insight into weather patterns, how long hot spells and cold spells tend to last, and the magnitude of these weather anomalies. We also use this information to confirm system sizing differences between sites due to weather conditions. As an example, through evaluating two sites less than 35 miles apart in the Portland, Oregon area of the US, it was determined that a cooling

tower selection for the western site location would require a cooling tower fan motor increase from 3 horsepower to 7.5 horsepower to meet the same indoor design conditions. These comparisons can provide insight into optimal site locations with respect to impacts as a result of weather. These analyses can review weather trends going back as far as recorded data can be sourced, in most cases up to 50 years in the past. This trend data can identify weather pattern changes that can occur due to urbanization such as converting open field to commercial developments and industrial usage. It can also provide information related to climate change which is affecting peak weather conditions. Through detailed review of this data, additional information can be provided to influence decisions on what worst case design condition should be included in the design. The design conditions published by ASHRAE and other resources provide single points of peak weather while the additional data collected and analyzed by AlfaTech can identify trends that can result in a more cost-effective design.

CFD / WIND ANALYSIS

In order to complete a design for advanced facilities, there are often requirements to validate the design approach using computational fluid dynamic (CFD) models. CFD models can simulate a variety of design conditions for both interior and exterior airflow conditions. AlfaTech has developed modeling techniques for both interior and exterior airflow modeling scenarios. Exterior CFD models can be used to analyze a building’s performance under prevailing or common wind conditions (speed and direction). These exterior models can help to influence design of outside air intakes, exhaust or relief openings, pressure sensor locations, and orientation of buildings to achieve optimal air flow. A common use of exterior wind models for mission critical data center facilities is to confirm standby or emergency generator performance. Typical diesel generators draw in combustion air and exhaust the products of combustion which can range from 500°F up to 1,000°F. The exhaust plumes can, if improperly designed and arranged, be drawn into outside air intakes or otherwise artificially influence the performance of neighboring equipment. Due to the high temperature and relatively small volume of combustion air required, these plumes tend to rise rapidly and as such, may not impact surrounding equipment performance. In addition to combustion air, a

typical generator draws in and exhausts significant airflow for radiator cooling. These airflow rates can have a larger impact concerning performance of surroundings systems, and thus modeling is necessary to ensure required system performance is achieved. Through wind modeling on previous projects, AlfaTech has been able to advise on proposed equipment placement, building arrangements, recirculation concerns, fresh air flow, and other elements to create an optimized design. Interior CFD models can be used to model airflow within a data center. Particularly when an underfloor air plenum design strategy is used, an airflow model can assess the floor height, the impact of underfloor obstructions, and the placement of air handling systems. In addition, indoor CFD models can assess the flow of air at the server rows to address hot spots, hot air recirculation, dead zones, and proposed phasing strategies. Through the use of CFD, AlfaTech can help clients optimize their design to ensure proper performance and operation of the completed design.

BUILDING INFORMATION MODELING (BIM)

Building Information Modeling (BIM) is a common tool referenced in the industry, but the concept covers many topics beyond just completing design in three dimensions as most people assume. 3D design is merely the tip of the iceberg when it comes to the full power and potential of BIM. At AlfaTech, we have been leading the industry using BIM for 3D design efforts, initially through the use of AutoCAD MEP and more recently through the design tool Revit. Through the use of Revit, AlfaTech can coordinate the design elements for our mechanical, electrical, plumbing, and technology designs with the balance of the building design such as architectural and structural elements. Beyond the standard usage of BIM for 3D coordination, AlfaTech uses the Revit platform to define parameters in design elements that can further influence robustness of design. Through intelligent modeling, our Revit designs can adapt and change pathways and riser diagrams as the system designs change. Importing information from Excel or other database software can also allow for rapid updating of the building model elements. An updated building model can then be used to update system design elements, energy performance of the design, and to consider design options. Through integrated viewing and coordination software such as Navisworks, Revizto, and Fuzor, the model can be further coordinated to ensure a conflict-free design with optimum system and pathway designs. This software also allows for virtual reality reviews of the project design to allow for better visualization of the completed project.

Review of the proposed installations allows end users, maintenance staff, and other critical decision makers the opportunity to truly see and experience the completed arrangement in a way that renderings, section views, and elevations did not allow. AlfaTech continues to innovate in the area of BIM, and to influence the software providers and provide our extensive knowledge and experience as a benefit to our clients. This results in a better coordinated, optimized result for our clients.

INTEGRATED BUILDING MANAGEMENT SYSTEMS ( IBMS )

The ‘Internet of Things’ (IoT) is creating new possibilities for building owners, product manufacturers and systems integrators, allowing the evolution of intelligent buildings to move at a rapid pace. IoT and analytics can be defined as a large number of data points brought together into a networked environment using one common Internet Protocol (IP) platform, allowing connected devices in a building to exchange and analyze information to optimize building and end-user efficiencies through automated controls. This evolution is how Smart Buildings are taking operational and energy efficiency to the next level through an Integrated Building Management Systems (IBMS) approach. The convergence of information technology (IT) systems that includes any use of computers, storage and networking devices and operational technology (OT), traditionally associated with manufacturing and industrial environments is reshaping how companies embrace IT/OT. Operational technologies seen in commercial office buildings consist of a number of facilities sub-systems including BMS, EMS, lighting controls, shade controls, security systems, conference room schedulers and more. Historically, all of these sub-systems operated independently of each other. Today we are seeing building sub-systems become network- enabled at an increased rate, creating a new generation of intelligent buildings. This transformation is placing new demands on the traditional corporate IT network, as all of these systems must communicate over a converged managed network. OT’s modernization through IT integration brings with it the required consideration of network and information security. Many OT systems were never

designed for network security, as a result, the risk of connectivity was not considered. Security breaches and threats have sharply increased both IT and facilities manager’s concern about allowing these ‘unknown’ devices on the corporate network. The vulnerabilities of OT systems can leave organizations and critical infrastructure at risk of industrial espionage and sabotage. IBMS is a network and applications architecture that enables IT/OT integration between facilities sub-systems through open protocols and open source application program interface (API). The key to successful intelligent buildings is to establish secure integration between sub-systems to enable collective monitoring, reporting, analytics and automation. A successful implementation can reduce cost by optimizing operational and energy efficiencies. These capabilities allow for more strategic space planning and enhance the employee experience and productivity. AlfaTech is uniquely positioned to guide and assist our clients through this complex process. With combined MEP and technology design and consulting services, we understand how to engineer these solutions from both the building facilities systems and the IT network, server and applications perspective. Intelligent Buildings require a close partnership and shared strategic vision between Facilities and IT. Through our experience and technical expertise, AlfaTech continues to guide clients through this evolution, helping them embrace and navigate the complexities of truly integrated building management systems.

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.

The key sections of a Data Center Strategy include:

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.
