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)]. 18
Examples of environmental performance measures for a spatial development project are shown in the table below: Environmental theme Performance soil ■ Soil sanitation performance units energy ■ Energy Performance at Location (EPL) for area development ■ Energy Performance Coefficient (EPC) for the building level external safety ■ (Vulnerable) functions within risk contours noise ■ (Number of) residences suffering noise hindrance, divided into classes of noise odour ■ Number of persons suffering from (seriously) offensive odour air ■ Surface area below the limit for nitrogen dioxide (NO2) and particulate matter in air (PM10) mobility ■ Accessibility of residences / places of work by public transport (average distance) ■ Comfortable and safe cycle paths ■ Parking standards nature ■ Protected natural areas use of space ■ Floor space index (net or gross) It is advisable to discuss the use and assessment of indicators in projects with both the project leader and the experts involved. This component is intended as a working document for specialists and the project leader. Aspects are highlighted according to the phase of the planning development and the insights into the feasibility of the goals. The second component, the environmental profile, focuses on information regarding opportunities for improvement. It is crucial for the communication of the environmental message that the environmental goals contribute to the improvement of the entire quality of the plan. The environmental profile should translate the environmental inventory data as far as possible into development-oriented information. A key issue is that of feasibility: i.e. ‘Is it possible and evident in practice?’, coupled with the influence of policy and conditions and the perception of end users. This includes a synopsis of: Opportunities ■ an impression of the area: the essential characteristics of the area that give direction to the environmental goals (layer approach, environmental situation in the area) ■ the functions and usage: the functional characteristics with the programme assignments ■ an impression of the market opportunities: the points of departure for the social and financial feasibility of the ambitions ■ the environmental accents: a more detailed account of special environmental qualities, selected on the basis of local circumstances. This can be assisted with reference to imagery and to-the-point information. Impressions 19
