Opportunities to Save Energy Now with Intelligent Industrial Buildings

摘要

In September 2005; in response to'extensive energy infrastructure damage by Hurricane Katrina, the. Secretary of Energy initiated a multi-sector plan to reduce energy consumption on' a national scale. In the industrial sector, "Save EnergyNow" provides an integrated approach to reduce energy consumption. 'This effort was initially focused on steam and process, heating assessments, training, technical assistance, and subsequent implementation tracking One area; which has not been addressed in these large. facilities, -is building systems including HVAC, lighting, and building envelope. As a matter of course, these systems are addressed by DOE's Industrial Assessment Centers, (IAC) however, these are primarily for small- and medium-sized establishments (SME). On average, buildings systems represent 5% of industrial energy consumption or 2.1 .Quadrillion BTU industry-wide. .including electrical systeni losses (DOE 2002). This is, roughly equivalent to all energy consumed by the U.S. Food Processing, industry (NAICS 311). Drawing from past and current experience, this paper will attempt to identify, categorize and rank industrial buildings related types of technologies and best practices such as HVAC, lighting, and building'envelope insulation and. rate their relative applicability to U.S. industry. This paper will highlight a. few Industrial Technologies Program (ITP) sponsored technologies that could reduce "building" (HVAC and lighting) energy use in industrial facilities, which is an important but often overlooked component of industrial energy use. The IAC database is used to illustrate the often-untapped potential for industrial buildings energysavings,,and.to illustrate the magnitude of energy savings and cost-effectiveness of generic strategies.
