Total Site Solutions' design services provide a seamless transition from planning to the formal design engagement. Our in-house staff applies extensive, real-life experience in critical environmental, power, communications and security systems to deliver precise engineering solutions that are ready for the unique needs of the specialized facility.

TSS’ understands that Data Center environments are different from occupied commercial space environments. Many of the commercial design methodologies are either outdated or inefficient and, when applied to Data Centers, result in increased energy consumption and lower system efficiencies. From this perspective, we have abandoned these legacy design practices and focus on implementing the following innovative design strategies:

• Hot or Cold Aisle air containment
• Integrated Rack / Cabinet selection and Cable Plant design
• High efficiency UPS and PDU's
• Variable Primary pumping systems
• High delta cooling
• Non condensing loops with >60 F Chilled water temperatures
• Thermal storage systems (where applicable)
• Use of economizers to capture the natural cooling cycles of Mother Nature
• Redirecting waste heat from the IT equipment for other uses in buildings or processes
• Use of renewable energy where possible
• Use of exterior building and site development features to reduce energy consumption

All the solutions mentioned above are available today, sometimes with associated increases in project capital cost, but always with significant realizations in savings of the total cost of ownership (TCO). These strategies translate directly to lowering the facility Power Usage Effectiveness (PUE).

No matter what strategies are put in play, our experience has shown that the most important factor to an energy efficient design without reducing reliability or maintainability is Right Sizing. This important information is built from the Information Technology power starting point, the life-cycle growth trends and, ultimately, the size of the connected infrastructure. With this critical data in-hand, we can achieve an effective mechanical/electrical plant design, with the highest possible efficiency and power factor from the mission’s earliest stage throughout its useful life. An accurate growth model also helps to plan a system that is modular and scalable with ideal step sizes, maximizing efficiency throughout the Data Center’s lifespan.

Finally, to ensure our designs deliver the intended results, we use a set of tools throughout the design process. These tools include specific software for load calculations to determine coincident, peak power and resulting cooling load. Loads are also calculated using a custom spreadsheet program to ensure quality control of data. Where life cycle cost analysis is required, TSS typically conducts a second analysis using DOE’s Equest application or a customized spreadsheet (depending on the project's complexity). We also utilize computational fluid dynamics (CFD) software to help design space layouts of a more complicated nature, where high density applications and/or non-standard architectural elements are present. All calculations are conducted using TSS' full-time engineering staff. These tools collectively allow us to build “what if” scenarios and compare different factors of system performance at varying loads.
