Accounting: Facility Energy Use

Abstract Energy Accounting is the management technique that quantitatively monitors energy consumption, relates consumption to key independent variables such as production and weather, and assesses energy performance or efficiency over time and against relevant benchmarks. The successful practice of energy accounting is predicated on the identification of the right kinds of data to be collected, […]

Air Emissions Reductions from Energy Efficiency

Abstract Energy efficiency has become a popular buzz phrase in the 21st century, but in addition to the pure economic cash savings that can be affected from implementing such work there is also the potential for a cleaner environment. Since becoming operational in February 2005, the Kyoto Treaty calls for a reduction in greenhouse gases […]

Air Quality: Indoor Environment and Energy Efficiency

Abstract In the days following the oil embargo of 1973, it became common practice to cover outside air intakes. This was just one of many actions taken by the uninformed in the hope of reducing energy consumption. Many of these measures, unfortunately, had a negative impact on the quality of the indoor air. Out of […]

Aircraft Energy Use

Abstract The aviation industry consumes a relatively small amount of the world’s fossil fuels. It has a solid record of reducing its consumption and is driven to do so by the large economic impact of fuel costs on the industry. Fuel consumption has been reduced by constant change and improvement in engine and airframe technology, […]

Alternative Energy Technologies: Price Effects

Abstract The world is now facing the reality that fossil fuels are a finite resource that will be exhausted someday, that global consumption is outpacing the discovery and exploitation of new reserves, and that the global environment is worsening due to increasing greenhouse gas (GHG) emissions caused by traditional fossil fuels. As a result, there […]

ANSI/ASHRAE Standard 62.1-2004 (Energy Engineering)

Abstract American National Standards Institute (ANSI)/American Society of Heating and Refrigeration and Air-Conditioning Engineers, Inc. (ASHRAE) Standard 62.1-2004 is a short but often misunderstood document outlining ventilation requirements intended to provide acceptable indoor air quality (IAQ) for new buildings or those with major renovations. Because of the rate-based nature of both procedures allowed for compliance, […]

Auditing: Facility Energy Use

Abstract This entry discusses the energy audit and assessment processes, including the analysis of utility data, walk-through assessments, detailed assessments, and the reporting of results. This article will also provide a brief history of energy auditing, as well as a look toward the future. INTRODUCTION Energy assessments are associated with energy conservation programs and energy […]

Auditing: Improved Accuracy (Energy Engineering)

Abstract A frequent criticism of the quality and accuracy of energy audits is that they overestimate the savings potential for many customers. This entry discusses several problem areas that can potentially result in over-optimistic savings projections and suggests ways to increase quality and produce more accurate energy audits. Performing an energy and demand balance is […]
