c) The perception and wishes of the market parties and (future) users
Consultation with developers and other interested parties in the area
can provide valuable insights into the feasibility of environmental goals.
Innovation is largely a result of market forces where cost-benefit
analysis can show long-term gains. Governments also have a role to
play, and they can impose goals and/or provide additional investment,
subsidies and maintenance budgets. An example of this is the public
tender put out by the municipality of Almere for the power supply to a
new housing estate, which included the condition that at least a 50%
reduction of CO2 should be achieved, compared to a regular power
supply. This led to a facility with a CO2 reduction of 90%. In general,
however there is still too little historical-based information regarding
the cost-effectiveness of environmentally-based technologies.
3. Components of the Environmental Profile
The environmental profile for projects in Tilburg consists of two components:
The first part is the summary of environmental qualities which shows
schematically per quality:
Perceptions
■ the quality indicator: the criterion with which the intended environmental
quality is expressed for the project.
The municipal environmental demands and wishes are preferably
expressed in the environmental profile with the help of indicators.
Measure-oriented criteria, such as ‘the use of solar energy’, or
qualitative goals, such as ‘compact building’ are not very directional or
measurable. A performance-oriented formulation of quality goals works
well, such as the ‘energy performance at location’ (EPL). The advantage
of this is that finding solutions for realizing the desired performance is
left entirely up to the developing party.
■ the basic quality: the minimum quality according to legal or policy
regulations for the assignment in question.
The lower limit is normally formed by statutory minimum levels or
maximum permissible risk (MPR). In some cases municipal policy leads to
a different (higher) basic quality being formulated. For example it may be
decided that the (good) existing risk situation should be taken as
starting point for plans (standstill).
■ the area ambition: the plusses, taking into account the local circumstances.
To facilitate national policy, a more far-reaching ambition per
environmental aspect is formulated for the projects in addition to the
‘basic’ environmental quality wherever possible and relevant. In this way a
set of bandwidths is created for environmental aspects per plan area.
This provides space for assessment for spatial development initiatives.
■ actions; the necessary activities for the further achievement of the
intended quality.
■ accents at building level; the continued effect of the selected goals on
the building [the ‘Gemeentelijke Praktijk Richtlijn-GPR (Municipal Practical
Guideline)].
