Energy Management Systems (EnMS) are a set of business processes that enable facility managers to act on energy usage data and optimize efficiency while identifying areas for improvement.

Buildings and facilities rely on the operation of mechanical systems and electrical systems to maintain a high level of indoor environmental quality for occupants. Building operations consume approximately 40% of the energy and 74% of the electricity produced annually in the United States, according to the U.S. Department of Energy. Greenhouse gases are generated and released for the production and consumption of the fossil fuel energy used in buildings. These greenhouse gases directly contribute to air pollution and climate change. Therefore, atmospheric problems can be reduced by increasing the efficiency with which energy is used‚ optimizing the use of natural energy resources‚ and understanding the effects of energy technologies on the atmosphere.

Indoor Environmental Quality (IEQ) is most simply described as the conditions inside the building. It includes air quality, but also access to daylight and views, pleasant acoustic conditions, and occupant control over lighting and thermal comfort.

In the construction and day-to-day operations of buildings, many materials and resources are used and a great deal of waste is generated. The materials selected for use in a facility and the way they are disposed of impact the environment.

Environmental programs, both federal and third party, help buyers identify products and services with positive environmental attributes.  Many federal environmental programs, such as ENERGY STAR and BioPreferred, are mandatory for federal buyers. 

Sustainability Programs incorporate all building stakeholders into the design process, promoting awareness, goal development, implementation, acceptance, and effectiveness of facility sustainability efforts.

Buildings are significant users of the Earth’s freshwater supply. The goal of a responsible building operator should be to encourage a smarter use of water, both inside and outside the facility.  Indoor water use reduction is typically achieved through efficient plumbing fixtures, fittings, appliances and process equipment used to heat and cool the building; outdoor water use reduction efforts should focus on water-wise landscaping and efficient irrigation.

Plug loads refer to energy used by equipment that is plugged into an outlet. In an office, key plug loads include computer and monitors, printers, and copiers. Plug loads can average approximately 30% of electricity use in office settings, much of which can be attributed to parasitic loads (or the power draw of a plug-load that is not performing useful work).

Plug loads as a share of overall building energy use is higher in energy efficient buildings. In minimally code-compliant office buildings, plug loads may account for up to 25% of total energy consumption. But in high efficiency buildings, plug loads may account for more than 50% of the total energy consumption.

You can reduce plug loads by up to 50% at your facility by utilizing an integrated team approach and implementing simple, no cost and low cost plug load control strategies.Explore the Plug Load section to discover the importance of advanced power strips (APS), occupant education and power management in combating these energy-wasters.

Because children spend such long hours at child care centers, the design of their spaces is especially critical. The design effort must allow for, and be sensitive to, the differences in space attributes for children and those for adults as well as the differences in space usage by the children in different age groups.

The challenge for building design and operations is to identify and eliminate health risks while also providing positive physical, emotional, and social supports as well as coping resources.
