3. Building codes types
 Prescriptive. They set a separate requirement for each building element and/or piece
of equipment (i.e. U-value for windows and walls), which had to be met.
 Trade-off: Some prescriptive codes offered more freedom to the designer by allowing
a trade-off between energy requirements (i.e. between U-values of the building shell).
Therefore it was possible to design one element to a lower standard so long as it was
compensated by designing another to a higher standard.
 Reference buildings or Model buildings: The energy consumption or losses of the
model or a reference building are calculated based on values set for each part of it.
The energy consumption or losses of the building under consideration are then
calculated using the same methodology and the results are compared to the reference
building. The design should be at least as good, if not better. This methodology allows
designers more freedom in choosing which cost-optimum solution to implement.
 Energy Frame: maximum energy losses from the building are set, usually set as a total
frame for the building, a value per m2 building area or a combination.
 Performance based: Total energy requirement is set.
This approach is the one that gives a clear indication of
the resulting environmental impact in terms of energy
consumption and CO2 emissions

4. Interaction avec other policies
 Energy labels/certificates are usually
based on building codes methodologies
 Economic instruments, when targeting
building envelope (which is rare), apply
for buildings with improved envelope
compared to the requirements in the
existing energy building code
 Building codes are too technical and not
easy to understand
 Enforcement is usually missing
