The General Services Administration is not just replacing aging heating and cooling equipment and reducing maintenance costs at the 670-acre Denver Federal Center (DFC). The GSA is also helping the government save about $450,000 in annual energy costs, conserve nearly 11 million gallons of water per year, and reduce annual carbon dioxide emissions by 15.9 million pounds, all by making use of the Department of Energy's Super Energy Savings Performance Contracts (Super ESPCs) at the DFC. Under these contracts, an energy services provider pays the up-front project costs and is then repaid over the contracts term out of the resulting energy cost savings. This two-page case study, prepared by NREL for the DOE Federal Energy Management Program (FEMP), demonstrates how the GSA forged new project partnerships, improved the DFCs boiler plant, and acquired efficient new chillers, motors, controls, and lighting by placing two delivery orders for this work under FEMPs Central Region Super ESPC.

Most school administrators and board members today must perform a tough juggling act. You're challenged to fulfill increasingly complex educational missions, meet rising community expectations, and serve growing student populations all with constrained operating budgets. As districts consider renovating their facilities or building new schools, many have found that smart energy choices can have lasting benefits for their schools, their communities, and the environment.

The sourcebook is a reference for industrial steam system users, outlining opportunities to improve steam system performance. This Sourcebook is designed to provide steam system users with a reference that describes the basic steam system components, outlines opportunities for energy and performance improvements, and discusses the benefits of a systems approach in identifying and implementing these improvement opportunities. The Sourcebook is divided into the following three main sections: Section 1: Steam System Basics--For users unfamiliar with the basics of steam systems, or for users seeking a refresher, a brief discussion of the terms, relationships, and important system design considerations is provided. Users already familiar with industrial steam system operation may want to skip this section. This section describes steam systems using four basic parts: generation, distribution, end use, and recovery. Section 2: Performance Improvement Opportunities--This section discusses important factors that should be considered when industrial facilities seek to improve steam system performance and to lower operating costs. This section also provides an overview of the finance considerations related to steam system improvements. Additionally, this section discusses several resources and tools developed by the U. S. Department of Energy's (DOE) BestPractices Steam Program to identify and assess steam system improvement opportunities. …

This is one of a series of technology fact sheets created to help housing designers and builders adopt a whole-house design approach and energy efficient design practices. The fact sheet advises how to create a comfortable basement environment that is free of moisture problems and easy to condition.

Final results of the New York City Transit Hybrid-Electric Transit Bus Study. Hybrid buses had lower emissions, higher fuel economy, and higher operating costs compared with diesel buses. New York City Transit (NYCT), part of the Metropolitan Transportation Authority in New York, began operating the first of 10 heavy-duty diesel hybrid-electric transit bus prototypes (Model VI) from Orion Bus Industries in 1998. All 10 buses were in revenue service by mid-2000. The hybrid buses are intended to provide NYCT with increased fuel economy and lower levels of harmful exhaust emissions, compared with NYCT's diesel transit buses. Between 1999 and 2001 (over various predefined fuel and maintenance evaluation periods), these first 10 hybrid buses were part of a data collection and analysis project sponsored by the U.S. Department of Energy (DOE). The operating costs, efficiency, emissions, and overall performance of these low-floor hybrid buses were compared against those of 14 conventional high-floor diesel transit buses (7 each from NovaBUS Corporation and Orion) operated by NYCT in similar service. Results indicate that the hybrid buses operate with greater fuel efficiency and much lower emissions, compared with the diesel buses. Maintenance costs for the prototype hybrid buses were significantly higher than those of …

Simple Linux Utility for Resource Management (SLURM) is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for Linux clusters of thousands of nodes. Components include machine status, partition management, job management, scheduling and stream copy modules. The design also includes a scalable, general-purpose communication infrastructure. This paper presents a overview of the SLURM architecture and functionality.

This case study highlights International Truck and Engine Corporation's optimization project on the compressed air system that serves its foundry, Indianapolis Casting Corporation. Due to the project's implementation, the system's efficiency was greatly improved, allowing the foundry to operate with less compressor capacity, which resulted in reduced energy consumption, significant maintenance savings, and more reliable production.

This OIT BestPractices Case Study describes how the Equilon Enterprises oil refinery in Martinez, California undertook a plant-wide energy assessment that focused on three key areas: waste minimization, process debottlenecking, and operations optimization. The assessment yielded recommendations, which, if implemented, can save more than 6,000,000 MMBtu per year and an estimated $52,000,000 per year, plus improve process control and reduce waste.

School districts around the country are finding that smart energy choices can help them save money and provide healthier, more effective learning environments. By incorporating energy improvements into their construction or renovation plans, schools can significantly reduce their energy consumption and costs. These savings can then be redirected to educational needs such as additional teachers, instructional materials, or new computers.

Operating a typical school today is no easy task for facilities managers and business officials. You're expected to deliver increased services with constrained operating budgets. Many schools stay open for longer hours to accommodate community use of the facilities. Dilapidated buildings and systems gobble up energy, yet in many districts, maintenance needs are overshadowed by the need for expansion or new construction to serve growing student populations and changing educational needs.

Additional steam traps were installed on the drum oven at a petroleum jelly production facility at an ExxonMobil plant in Nigeria. The installation improved heat transfer and saved energy.

The connectivity interface for UnstructuredMapping has been rewritten to provide a more thorough interface to the mesh. This new design also resembles the TSTT mesh query interface. While data is still stored in array form, indexed by integers, the interface provides iterators through the mesh entities and adjacencies. This document describes the additions to the UnstructuredMapping class as well as the definition and use of the UnstructuredMappingIterator and UnstructuredMappingAdjacencyIterator classes.

This database tool provides a structured approach to recording design decisions that impact a facility's design intent in areas such as energy efficiency.Owners and de signers alike can plan, monitor and verify that a facility's design intent is being met during each stage of the design process. Additionally, the Tool gives commissioning agents, facility operators and future owners and renovators an understanding of how the building and its subsystems are intended to operate, and thus track and benchmark performance.
