Sub-Metering a Hotel for LEED Certification
This white paper examines LEED® certification at the Proximity™ Hotel in Greensboro, North Carolina. LEED certified buildings must be energy efficient and they must establish an on-going measurement and verification program to monitor energy consumption. Sub-metering makes detailed measurement and verification possible.Click here to read more
Making The Case For Energy Metering
What do a building's energy meters and an automobile's gages for speed, gas, oil, water and engine temperature have in common? They control nothing, but provide vital information to help a design engineer or operator maximize equipment operations. Considering that energy costs represent a substantial portion of a building’s operating budget, energy metering...Click here to read more
Industrial Energy Monitoring Case Study
"As facility manager for Schneider Electric's Huntington and Peru, Ind., plants, John Troyer is a busy man. He knows energy efficiency is important and his bosses have put it high on their long list of priorities, but he can’t devote a lot of time to monitoring and managing it. So he's glad that it usually takes less than a minute to open and review the e-mail message his system sends him each day, summarizing consumption and highlighting anomalies."Click here to read more
Campus Energy Management System 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..."

Commercial Building Energy Monitoring Case Study
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..."
