Requirements

Have in place a computer-based building automation system (BAS) that monitors and controls major building systems, including at a minimum, heating, cooling, ventilation and lighting. Have a preventive maintenance program in place that ensures BAS components are tested and repaired or replaced according to the manufacturer’s recommended interval. Demonstrate that the BAS is being used to inform decisions regarding changes in building operations and energy-saving investments.

Develop a breakdown of energy use in the building, either through EA Credits 2.1 and 2.2 or by using energy bills, spot metering or other metering to determine the energy consumption of major mechanical systems and other end-use applications. This analysis of major energy-use categories must have been conducted within 2 years prior to the date of application for LEED 2009 for Existing Buildings: Operations & Maintenance certification.

Based on the energy-use breakdown, employ system-level metering covering at least 40% or 80% of the total expected annual energy consumption of the building. Permanent metering and recording are required. All types of submetering are permitted.

Demonstrate that system-level metering is in place covering the percentage of total expected annual energy consumption of the building as outlined in the table below.

System Level Metering Requirements
Percentage of Total Annual Energy Consumption to be Metered Number of Largest Energy Use Categories to be Covered by 80% or more Points

40% 1 of 2

1
80%

2 of 3 2

Demonstrate that the number of the largest energy-use categories from the breakdown report outlined in the table are covered by at least 80% (i.e., if energy use in the 2 or 3 largest categories is each 100 Btus/year, at least 80 Btu/year in 1 or 2 of them must be metered).

Further, at least two of the three largest energy-use categories from the breakdown report must be covered to the extent of 80% or more.

Metering must be continuous and data logged to allow for an analysis of time trends. The project must compile monthly and annual summaries of results for each system covered. Meters must be calibrated within the manufacturer’s recommended interval if the building owner, management organization or tenant owns the meter. Meters owned by third parties (e.g., utilities or governments) are exempt.

  • any individual energy end uses that represent 10% or more of the total annual consumption of the building.

The advanced energy metering must have the following characteristics.

  • Meters must be permanently installed, record at intervals of one hour or less, and transmit data to a remote location.
  • Electricity meters must record both consumption and demand. Whole-building electricity meters should record the power factor, if appropriate.

Performance

Program the facility’s energy management system to set an alarm whenever the energy consumption and peak demand rise above the anticipated amount by more than 5%. The anticipated consumption and peak should be determined by analyzing historical facility performance and weather and operating conditions and should be set on at least monthly, preferably daily.

Demand measurements must be taken in time increments no longer than the increments used for utility billing or in one-hour increments, whichever is less time.

On at least a monthly basis, report the facility’s utility peak demand and total consumption and compare it with the data for the previous month and the same month from the previous year.
