Case Studies of Energy Information Systems and Related Technology: Operational Practices, Costs, and Benefits
Abstract
Energy Information Systems (EIS), which can
monitor and analyze building energy consumption
and related data throughout the Internet, have been
increasing in use over the last decade. Though EIS
developers describe the capabilities, costs, and
benefits of EIS, many of these descriptions are
idealized and often insufficient for potential users to
evaluate cost, benefit and operational usefulness.
LBNL has conducted a series of case studies of
existing EIS and related technology installations.
This study explored the following questions: 1) How is the EIS used in day-to-day operation? 2) What are the costs and benefits of an EIS? 3) Where do the energy savings come from? This paper reviews the process of these technologies
from installation through energy management
practice. The study is based on interviews with
operators and energy managers who use EIS.
Analysis of energy data trended by EIS and utility
bills was also conducted to measure the benefit. This
paper explores common uses and findings to identify
energy savings attributable to EIS, and discusses nonenergy
benefits as well. This paper also addresses
technologies related to EIS that have been
demonstrated and evaluated by LBNL.
