4.21. Reduce earthworks
Those articles which require a specific project about earthworks
are also included here; it is understood
that this is one way of keeping a check on them. We have various motives
for including this principle. Two of them are probably the most important.
First, because of energy saving and the reduction of pollution. The second,
because significant modifications to the topography of the land always
leads to problems with run-off water.
4.22. Foster the use of local materials
Generally associated with landscape protection
(the obligation to use local materials or similar).
4.23. Use building techniques that facilitate reuse
This criterion is closely related to the following one, although they do
not handle the same issue. Both, however, seek to breathe new life into
what has already been built or used. It is not easy to legislate for both
cases and the most sensible thing to do would probably be to put them into
a guide on sustainable construction or in a list of recommendations.
4.24. Foster the use of easily recyclable materials
The same applies here as for the previous principle.
4.25. Foster the shared use of service networks
Service galleries are the most clichéd example, although there are many
more.
