Advanced Concepts in Designing and Retrofitting Energy Efficient Data Centers (Part 1 of 2)

These previously recorded lectures are presented by Jeff Stein and Brandon Gill. The class will focus on how to select, design, control, and commission the mechanical systems with the lowest total cost of ownership (TCO) for a given data center. TCO accounts for first cost (including electrical, architectural and structural impacts), reliability, complexity/simplicity, energy efficiency, maintenance costs, future growth, and flexibility. The class will make liberal use of real data center case studies for both new construction and retrofits. Mechanical systems evaluated will include packaged/custom DX with air economizers, direct/indirect evaporative cooling, pumped refrigerant economizers, various chilled water systems including in-row cooling and waterside economizers, air-cooled chillers with integrated dry-coolers, liquid cooled racks, and liquid cooled servers. One area of focus will be controls design and commissioning. This section will cover both DDC and PLC systems, various controls redundancy options, fail-safe device configuration, optimizing/simplifying sequences of operation, and controls commissioning. The class will also review the ASHRAE TC9.9 Thermal Guidelines and other standards of care for control of temperature, humidity, gaseous contaminants, and particulates. Lastly, the class will cover the growing use of data center heat recovery. This is an advanced level course for owners, operators, engineers, contractors, colocation tenants, etc. with at least two years of data center experience. https://pge.docebosaas.com/learn/cour...
