Energy Solutions Center Case Study
"According to the DOE's (U.S. Department of Energy) Office of Energy Efficiency and Renewable Energy, on average 35% of the process energy used in manufacturing is lost through process inefficiencies and energy losses. This is one of the targets of DOE's Industrial Energy Systems subprogram. Through a wide range of partnerships with industry, this subprogram has identified opportunities for reducing energy losses and improving the energy efficiency of many industrial processes..."
Southface Case Study
New York's Kingston School District
"What have they done? The district replaced windows in some schools, upgraded boiler rooms with pulse boilers in others, upgraded facilities to high efficiency lighting, and incorporated a network computerized energy management system in all of their buildings resulting in a 35% reduction in energy costs per year..."
NJHEPS Case Study
"The College of New Jersey (TCNJ) is a 2.5 million square-foot campus in Ewing, New Jersey that encompasses fifty buildings, with new construction in progress or planned for ten more. Administrators, recognizing that energy was one of their largest operating expenses, resolved to find ways to analyze and manage these costs. In 1999, TCNJ began applying a state-of-the-art integrated information platform and metering technology to collect and analyze facility information, including total energy consumption. This capability enabled the Energy and Central Utilities staff to diagnose, recommend and implement timely solutions that help reduce costs, increase system reliability, and improve the facility environment.
Technology: Digital energy monitors; an energy management system and energy information database and analysis tools; utilized existing available campus-wide copper-wire network (eliminated requirement to run
additional network infrastructure).
CO2 Emission Reductions: 2400 tons annually.
Investment: $200,000
Annual Savings: $300,000..."

How Monitoring-Based Commissioning Contributes to Energy Efficiency for Commercial Buildings Karl Brown, California Institute for Energy and Environment, Mike Anderson, Newcomb Anderson McCormick, Jeff Harris, Lawrence Berkeley National Laboratory
"Monitoring expands the potential for reducing energy using two ways. First, monitoring compliments conventional functional testing protocol in the identification of wasteful dysfunction in building systems..Second, saving opportunities are often constrained measures for which savings can be calculated using accepted engineering assumptions. Opportunities that are difficult to predict in advance and require measurement to assess or verify the energy savings have gotten less attention..."
