Indexes as Guidelines for the Planning Phase
The analysis of the indexes already used by other administrations, the analysis of
the possible solutions to implement in yards and to cover buildings, and the analysis
of the respective physical and technical characteristics have made it possible to
obtain a complete and rational list of types of action, to be included in the experimental indexes. This list is the starting point for the various technical criteria
explained in the previous chapters for calculating the output of the indexes, and it
has been designed in such a way as to guide the planning in the implementation of
new buildings and in the upgrading of existing buildings. By defining the characteristics of the existing context and the possible planning solutions, planners receive
output which enables them to check the overall improvements achieved (in terms of
reduction of the RATE or HYPER index).
If planners intend to modify the overall improvements, they can change the combination of types of planned actions and obtain new outputs, to be compared with the
previous ones, in order to refine the planning and increase its environmental value.
The types of actions included in the indexes represent, therefore, a reasonable
and functional synthesis of planning guidelines, which can provide both support to
the architectural planning and an assessment of the impacts generated immediately
and with suitable precision.
6.1 Indexes and Economic Assessment
of Planning Solutions
As an integration to the planning support tools mentioned above, the indexes also
implement an assessment of the parametric costs of the various types of action
envisaged. By applying the same approach used for the assessment of impacts produced by the planning solution envisaged by the planner, a dynamic table has been
designed, relative to the parametric costs of planning actions.
In this way, planners check the types of action chosen which might be applied in
order to find the right balance between costs and resources. Moreover the planner is
able to verify the quality/cost ratio of each type of action.
In order to promote such analyses, the software shows the synthesis of all the
information relative to the two indicators and the parametric costs. By reading the
information relative to each type of action, it is possible to easily check and compare the impacts caused and the relative costs.
