SEDBUK was developed under the Government's Energy Efficiency Best Practice Programme
with the co-
SEDBUK is the average annual efficiency
achieved in typical domestic conditions, making reasonable assumptions about pattern
of usage, climate, control, and other influences. It is calculated from the results
of standard laboratory tests together with other important factors such as boiler
type, ignition arrangement, internal store size, fuel used, and knowledge of the
UK climate and typical domestic usage patterns.
For estimating annual fuel costs
SEDBUK is a better guide than laboratory test results alone. It can be applied to
most gas and oil domestic boilers for which data is available from tests conducted
to the relevant European standards. The SEDBUK method is used in SAP.
The SEDBUK development project
The purpose of the project was to develop a method
for calculating seasonal efficiency for individual central heating boilers to use
in the UK Building Regulations, Part L (Conservation of Fuel and Power).
The project
took place over a period of three years, during which a theoretical seasonal efficiency
model was developed for simple boilers and then adapted to include other types. Experimental
data obtained from detailed laboratory tests on over 20 different boilers, supported
by data from field trials in 99 homes, was used to validate the theoretical assumptions.
This allowed fuel usage data (termed "signature") to be related to efficiency test
results supplied by manufacturers.
The work was carried out for BRECSU on behalf
of the Department of the Environment, Transport and the Regions, with BG Technology
as the main contractor to provide technical expertise. At each stage the findings
were debated and agreed by members of the boiler efficiency project team, who represented:-
