Compressed Air Leak Detection and Repair (Energy Engineering)

Abstract Compressed air is a major cost component in manufacturing. As such, it offers one of the largest savings opportunities. The investment in compressing air to energize it and then letting it escape from the system through leaks, without doing any useful work, is a complete waste. This waste can be minimized by implementing a […]

Compressed Air Storage and Distribution (Energy Engineering)

Abstract Consistent stable operation of an industrial compressed air system is achieved when compressed air flow supplied to the system equals compressed air demand. Energy distributed to the system is available from two sources; rotating energy of the air compressors, and energy from compressed air storage. Optimum system energy efficiency is possible when the proper […]

Compressed Air Systems (Energy Engineering)

Abstract Compressed air is a valuable resource for manufacturers, allowing the use of pneumatic-driven hand tools, which can be an ergonomic boon to employees. This resource comes with a price, however, in the form of higher energy costs. This article describes the use of compressed air and the creation and delivery of compressed air from […]

Compressed Air Systems: Optimization (Energy Engineering)

Abstract This article will provide you with an complete action plan to optimize your compressed air system including compressor optimization, demand management, density management, and storage in a variety of different applications. Compressed air represents one of the most critical utilities in most production and process environments. The efficiency of a compressed air system is […]

Cooling Towers (Energy Engineering)

Abstract Cooling is necessary to many industrial processes, such as power generation units; refrigeration and air conditioning plants; and the manufacturing, chemical, petrochemical, and petroleum industries. As recently as 20 years ago, cooling towers were more the exception than the rule in the industry because of their high operating cost and the large capital required […]

Data Collection: Preparing Energy Managers and Technicians

Abstract Energy audits can be used to provide hands-on activities related to an energy management course. After learning the necessary background concepts, students need to be aware of what measurements must be taken to evaluate an existing energy system. In industry and universities, one may find apprentices and students from different educational backgrounds, such as […]

Daylighting (Energy Engineering)

Abstract Daylight illumination of building interiors is an ancient art now benefitting from relatively recent engineering advances. The benefits are numerous and include energy savings and enhanced visual and thermal comfort. The design must avoid overheating and the discomfort and reduced productivity resulting from glare. Good daylighting design can displace electric lighting and reduce air […]

Demand Response: Load Response Resources and Programs (Energy Engineering)

Abstract “Demand response” is a relatively new term to the electric utility industry for an old concept called peak load management. Demand response has gained currency, as the historically cumbersome peak load management programs have been transformed by real-time monitoring, digital controls, and robust communications. The costs of managing demand response resources have become more […]

Demand Response: Commercial Building Strategies (Energy Engineering)

Abstract This paper describes strategies that can be used in commercial buildings to temporarily reduce electric load in response to electric grid emergencies in which supplies are limited or in response to high prices that would be incurred if these strategies were not employed. The DR strategies discussed herein are based on the results of […]

Demand-Side Management Programs (Energy Engineering)

Abstract Demand-side management is the active planning and implementation of programs that will change consumers’ use of electricity. These programs may encourage the adoption of more efficient appliances, the use of new technologies, and the time these and other devices are used. INTRODUCTION Demand-side management programs result from the planning and implementation of those activities […]
