- Base temperature
- In the calculation of degree day values, the outside air temperature at which the building requires no artificial heating (or cooling, as the case may be). For guidance on establishing the correct base temperature see
- Commonly a figure for annual quantity of energy used as a reference against which
to compare future consumption when evaluating savings, ideally adjusted to account for
differences in circumstances (esp. weather and production etc.) between the
two years being compared. A better approach might be to think of a baseline performance
characteristic, that is, the model which historically described the relationship between consumption
and its driving factor(s). By substituting reporting-year values for said driving
factor(s) one arrives directly at an estimate of the consumption that would have occurred
in the absence of intervening changes in energy performance. This permits the absolute
saving to be calculated.
- Benchmarking between heating systems
- Building Energy Management System. Computerised system for sensing conditions within a building
and controlling the delivery of heating, cooling, etc., in accordance with time schedules.

- If you suspect that a product is being advertised with false claims, or even just
that the claims cannot be substantiated, it is possible to complain to the Advertising Standards
Authority (see for example this
in the case of the so-called "current optimization" device marketed by Blue Carbon).
