Energy Conservation AARCHER's Energy Conservation team is dedicated to decreasing the quantity of energy used in operating administrative, commercial and industrial facilities. Our customers see cost savings of 10-40% with a rapid return on investment (ROI) "payback." AARCHER's Energy Conservation practice is led by Dr. W. Travis Horton, P.E.; Ph.D. Dr. Horton, a professional engineer and professor of Architectural Engineering at Purdue University, is a nationally recognized expert in the field of energy conversion systems, including heating, air conditioning, refrigeration, and electrical systems; combined heat and power systems, and building energy modeling tecnhiques. Energy Audits Energy audits range from a rapid visual evaluation of a facility to identify potential major energy-saving opportunities to comprehensive analyses of possible energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors. Following are overviews of common audit programs; however, each audit level can be customized to meet particular management objectives and unique facility conditions. AARCHER can provide sample scopes of work upon request. Preliminary AuditThe preliminary audit is the simplest and fastest type of audit. It involve minimal interviews with site operating personnel, a brief review of facility utility bills and other operating data, and an inspection of the facility to identify areas of energy waste or inefficiency. Typically, only major problem areas and simple "low hanging fuit" corrections will be uncovered during this type of audit. Corrective measures are briefly described, and quick estimates of implementation cost, potential operating cost savings, and simple payback periods are provided. Complete Site Energy Audit The complete site energy audit expands on the preliminary audit by collecting more detailed information relating to facility operation and performing a more detailed analysis of energy conservation measures identified. Utility bills are collected for a 12- to 36-month period to allow the auditor to evaluate the facility's energy/demand rate structures, and energy usage profiles. Additional metering of specific energy-consuming systems is often performed to supplement utility data. In-depth interviews with facility operating personnel are conducted to provide a better understanding of major energy-consuming systems as well as insight into variations in daily and annual energy consumption and demand. This type of audit will identify all energy conservation measures appropriate for the facility, given its current operating paraments. A detailed financial analysis is performed for each measure based on detailed implementation cost estimates, site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation. Comprehensive Energy Audit In most organizations, upgrades to a facility's energy infrastructure must compete with non-energy related investments for capital funding. Both energy and non-energy investments are rated on a single set of financial critera that generally stress ROI. Projected operating savings from energy projects must be documented to provide a high level of confidence. A Comprehensive audit provides a dynamic model of energy use characteristics of both the existing facility and all energy conservation measures identified. Building models are calibrated against actual utility data to provide a realistic baseline for calculating predicted savings. Extensive attention is given to understanding not only the operating characteristics of all energy-consuming systems, but also conditions under which load profile varations can occur on both an annual and daily basis. Existing utility data is trypically supplemented with submetering of major energy-consuming systems and monitoring of system operating characteristics. |
