LEED, the Leadership in Energy and Environmental Design, is the largest driving force behind the increased development of green buildings in the world. One of the most important factors that LEED uses in their certification process is energy consumption and the owner’s ability to track usage and identify potential savings. While most conventional buildings have simple meters provided by the utility company for billing purposes, the advanced standards for LEED certification require more robust and more precise monitoring capabilities.
LEED’s advanced energy metering requirements demand added specificity beyond what can be manually observed from the utility’s billing meter. In addition, individual end uses must be submetered if they make up 10% or more of the building’s total energy consumption for the year.
In order to meet the advanced energy metering requirements, user-owned power meters must possess the following qualities and capabilities:
Whether called Multi-Load, Multi Circuit, Multi Channel or even Branch Circuit energy metering, Setra’s line of power meters lower the cost per metering point and measures with more granularity than other metering solutions on the market.
Measure More... For Less
Utilize the built-in configuration portal to easily map out what’s being measured to support any energy management strategy
Wire the voltage service lines, current transformers, pule I/O and communications wiring to the meter
Leverage the available BACnet or Modbus communications protocol to tie the meter into any existing or new EMS or BAS within the application
Identify what's going to be metered
Look across the installation and identify the equipment that are to be measured to support energy strategy
Examples: Chillers, Lighting, AHU’s, Tenant Usage
Count up how many CT’s are needed
Match the CT amperage to the breaker feeding the load or use Patrol Flex Coils (up to 1500A)
Single-Phase Service = 1CT
Split-Phase Service = 2 CT’s
Three Phase Service= 3 CT’s
Select Meter Part Number
Take the CT count and select the meter with the right number by matching the CT’s with available inputs
SPM03EDN = 3 CT inputs
SPM12EDN = 12 CT inputs
SPM48EDN = 48 CT inputs
