- Diagram depicting energy flows, in which relative quantities
of energy are represented by breadths of connected arrows.

- Supervisory Control and Data Acquisition: generic term for industrial
process control system. Use of a 'historian' (data logging) facility is
a convenient way to collect submeter consumption data.
- In an energy management scheme, the extent of activities, facilities and
energy sources that the organization addresses.
- Sensible heat
- Heat either released or absorbed which is accompanied by a change in
temperature (contrast latent heat).
- Sequence control
- Applied to banked equipment such as boilers, chillers, etc.; the process
of bringing units in and out of service to match demand, isolating surplus
units to minimise standing energy loss.
- Specific Energy Ratio, for example kWh per tonne of output. Frequently (and wrongly)
employed as an indicator of energy performance.
- Significant energy use
- In ISO50001, a type or manner of application of energy use which accounts
for substantial energy consumption or offers considerable potential for energy
- There are numerous products for energy monitoring and targeting
but often they are restricted to passive reporting. If your
interest is routine exception reporting and the detection
and diagnosis of avoidable energy waste click here
for an article giving guidance on selection criteria. For a wide
selection of other tools see EERE web site.
- Specific Energy Ratio
- See SER
- Specific heat
- Quantitative physical property of a material relating a
change in heat content to the corresponding change in temperature.
- Standard degree days
- Figures used as the basis of normalisation when comparing
energy consumptions of buildings in different regions
measured at different times in the past.
- Heat transfer medium mainly for industrial processes where
temperatures in excess of 100°C are required.
- Method of estimating the running power of a significant load
by taking successive readings of a consumption meter
with the load in question on and off.
