High-performance data centers: A research roadmap

This report was developed for the California Energy Commission to document industry input and LBNL research into research topics appropriate for public interest support. Industry experts identified research topics and along with LBNL findings, helped to prioritize the technical areas for future public interest research.

An energy efficiency guide for use in cleanroom programming

This guide was developed to provide ideas for considering energy efficiency in the early stages of a cleanroom design project. Use of this guide will facilitate selection of design features that will improve energy efficiency in cleanrooms. Cleanroom owners and designers can use the guide to focus on energy intensive items in the design of a cleanroom facility.

Money for Research, Not Energy Bills: Finding Energy and Cost Savings in High-Performance Computer Facility Designs

High-performance computing facilities in the US consume enormous amounts of electricity,, cutting into research budgets and challenging efforts to reduce energy consumption and meet environmental goals. Facility designs that target efficiency greatly reduce energy demand. This case study describes strategies and technologies to achieve facility energy reductions through thoughtful design.

General Recommendations for High Performance Computing Data Center Energy Management Dashboard Display

Within the past decade, there has been an increasing focus on improving energy efficiency in High Performance Computing (HPC). Improvements have been forthcoming, especially in the last 5 years, but there remains a strong need for continued if not accelerated progress. Much of this progress has been and will continue to be driven by market demands and the private sector. Some of the progress has been achieved by government-funded agencies and academic research. There are other mechanisms beyond these formal institutions; these mechanisms include volunteer and non-profit organizations that promote dialogue, analysis, best practices, standards and community activism. The Energy Efficient HPC Working Group (EE HPC WG) is such an organization and this paper describes an effort by the EE HPC WG to drive more rapid improvements in development and implementation of energy management dashboard displays.

Accelerating Energy Efficiency in Indian Data Centers: Final Report for Phase I Activities:

This report documents Phase 1 of the “Accelerating Energy Efficiency in Indian Data Centers” initiative to support the development of an energy efficiency policy framework for Indian data centers. The initiative is being led by the Confederation of Indian Industry (CII), in collaboration with Lawrence Berkeley National Laboratory (LBNL)-U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy, and under the guidance of Bureau of Energy Efficiency (BEE). It is also part of the larger Power and Energy Efficiency Working Group of the US-India Bilateral Energy Dialogue. The initiative consists of two phases: Phase 1 (November 2014 – September 2015) and Phase 2 (October 2015 – September 2016).

Data Center Energy Efficiency Standards in India

Global data center energy consumption is growing rapidly. In India, information technology industry growth, fossil-fuel generation, and rising energy prices add significant operational costs and carbon emissions from energy-intensive data centers. Adoption of energy-efficient practices can improve the global competitiveness and sustainability of data centers in India. Previous studies have concluded that advancement of energy efficiency standards through policy and regulatory mechanisms is the fastest path to accelerate the adoption of energy-efficient practices in the Indian data centers. In this study, we reviewed data center energy efficiency practices in the United States, Europe, and Asia. Using evaluation metrics, we identified an initial set of energy efficiency standards applicable to the Indian context using the existing policy mechanisms. These preliminary findings support next steps to recommend energy efficiency standards and inform policy makers on strategies to adopt energy-efficient technologies and practices in Indian data centers.

Cost Avoidance vs. Utility Bill Accounting - Explaining theDiscrepancy Between Guaranteed Savings in ESPC Projects and UtilityBills

Federal agencies often ask if Energy Savings Performance Contracts (ESPCs) result in the energy and cost savings projected during the project development phase. After investing in ESPCs, federal agencies expect a reduction in the total energy use and energy cost at the agency level. Such questions about the program are common when implementing an ESPC project. But is this a fair or accurate perception? More importantly, should the federal agencies evaluate the success or failure of ESPCs by comparing the utility costs before and after project implementation?In fact, ESPC contracts employ measurement and verification (M&V) protocols to measure and ensure kilowatt-hour or BTU savings at the project level. In most cases, the translation to energy cost savings is not based on actual utility rate structure, but a contracted utility rate that takes the existing utility rate at the time the contract is signed with a clause to escalate the utility rate by a fixed percentage for the duration of the contract. Reporting mechanisms, which advertise these savings in dollars, may imply an impact to budgets at a much higher level depending on actual utility rate structure. FEMP has prepared the following analysis to explain why the utility bill reduction may not materialize, demonstrate its larger implication on agency s energy reduction goals, and advocate setting the right expectations at the outset to preempt the often asked question why I am not seeing the savings in my utility bill?
