4 Benefits of Energy Benchmarking
In some states and cities, energy benchmarking is mandatory, and buildings are required to meet certain standards. Mandatory benchmarking is becoming more common as the U.S. grapples with the threat of climate change. Even if your city does not yet require benchmarking, it is still wise to participate, since your company can reap the following bene.
Design An Energy Benchmarking Plan
Having a benchmarking plan will help mitigate any initial confusion or uncertainty. Your plan should:. 1) State the purpose and goals for your benchmarking program and the intended audience for the results (Clients. Investors. Management teams?). 2) Identify what metrics are necessary to communicate the results clearly and how the data will be colle.
How can a building's energy performance be compared to other buildings?
A building’s energy performance can be compared on a statistical basis to a population of comparable buildings. Benchmarking tools that use this approach include:
the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager, Lawrence Berkeley National Laboratory’s EnergyIQ, and a host of proprietary tools.
How do you analyze a building's energy performance?
A few basic analysis techniques include:
Compare against the baseline—track a building's or facility's energy use against itself over time. Compare with energy simulation/energy modeling—use an energy modeling tool to evaluate a building's energy performance versus potential performance.
How does EPA measure energy performance?

Benchmarking of energy consumption
Sixfold rise in oil prices, peaking in 2008
From the mid-1980s to September 2003, the inflation-adjusted price of a barrel of crude oil on NYMEX was generally under US$25/barrel in 2008 dollars. During 2003, the price rose above $30, reached $60 by 11 August 2005, and peaked at $147.30 in July 2008. Commentators attributed these price increases to many factors, including Middle East tension, soaring demand from China, the falling value of the U.S. dollar, reports showing a decline in petroleum reserves, worries over peak oil, and financial speculation.
Energy Management Software
Energy Management Software (EMS) is a general term and category referring to a variety of energy-related software applications which may provide utility bill tracking, real-time metering, building HVAC and lighting control systems, building simulation and modeling, carbon and sustainability reporting, IT equipment management, demand response, and/or energy audits. Managing energy can require a system of systems approach.

US energy efficiency program
Energy Star is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) that promotes energy efficiency. The program provides information on the energy consumption of products and devices using different standardized methods. The Energy Star label is found on more than 75 different certified product categories, homes, commercial buildings, and industrial plants. In the United States, the Energy Star label is also shown on the Energy Guide appliance label of qualifying products.
Standard measure of the energy efficiency of a building
The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any international building energy rating scheme but there are some other important factors such as production of greenhouse gases emission, indoor environment quality, cost efficiency and thermal comfort, which are considered by some schemes. Basically, the energy rating of a residential building provides detailed information on the energy consumption and the relative energy efficiency of the building. Hence, HERs inform consumers about the relative energy efficiency of homes and encourage them to use this information in making their house purchase decision.
Sustainable energy management in the wastewater sector applies the concept of sustainable management to the energy involved in the treatment of wastewater. The energy used by the wastewater sector is usually the largest portion of energy consumed by the urban water and wastewater utilities. The rising costs of electricity, the contribution to greenhouse gas emissions of the energy sector and the growing need to mitigate global warming, are driving wastewater utilities to rethink their energy management, adopting more energy efficient technologies and processes and investing in on-site renewable energy generation.
Electronic systems’ power consumption has been a real challenge for Hardware and Software designers as well as users especially in portable devices like cell phones and laptop computers. Power consumption also has been an issue for many industries that use computer systems heavily such as Internet service providers using servers or companies with many employees using computers and other computational devices. Many different approaches have been discovered by researchers to estimate power consumption efficiently. This survey paper focuses on the different methods where power consumption can be estimated or measured in real-time.
