                                                              efficiency.
                                                                                                    © OECD/IEA 2011
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
                                                                                     © OECD/IEA 2011
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
