sustainable development. To ensure credits will only be awarded to
meaningful installations, the criteria of assessment have been set with
reference to the percentage of the energy use in the assessed building
that will be replaced by renewable sources. Furthermore, no distinction
will be made of the means chosen for substituting electricity or fuel by
renewable energy. Hence, different or a combination of systems and
equipment may be incorporated into a building, such as solar hot water
systems, building integrated photovoltaic panels or wind turbines, etc.
Recognizing the fact that the application of renewable energy in densely
populated urban centres is more difficult than in less densely populated
settings, the performance criteria are relaxed for building developments
in urban centres.
