Module 2: Frameworks for Spatial Planning and Energy
In all of the SPECIAL partner countries, urban land use planning forms part of the legal framework of the state. Therefore legally binding spatial planning instruments and procedures are employed within these states to underpin actions relating to energy and energy efficiency. Less formal systems can be employed at lower spatial scales (please see more information in Module 3).
Planners working at national, regional and local levels need to learn to include planning considerations when dealing with environmental concerns to sustainability, climate change (mitigation/adaptation), biodiversity and scarcity of resources.
Planning is an important instrument for the achievement of political climate protection objectives which are formulated on European, National and Municipality level (see policy objectives in 2.1). Planning systems are slightly different in the SPECIAL partner countries but the overall structures are mostly similar. European, national and local climate protection objectives and policies have to be implemented / concretized on subordinate spatial level (local area).
For the SPECIAL project, different legislative levels and sectors are relevant. Most important are:
On European level some Directives have an influence on national legislation relating to spatial planning and energy, such as the Directive on the “Energy performance of buildings” (2010/31/EU) or the Directive on the promotion of the use of energy from renewable sources (2009/28/EC). At a national level, all partner countries possess legislative instruments which give effect to European and national targets and objectives within that jurisdiction.
A distinction is drawn in spatial planning between comprehensive spatial planning and sectoral planning. Comprehensive spatial planning is cross-sectional at all planning levels, whereas sectoral planning addresses single, mostly technical infrastructure sectors, dealing with specific projects like railways, airports, and waterways. (ARL, 2008). In the most partner countries the legally binding legislation covers three government and planning levels:
The distribution of competence and functions between the three levels of government produces a system with legally, organisationally, and substantively differentiated planning levels. In Germany for example, federal spatial planning is limited essentially to the development of guiding principles of spatial planning which also provides the legal basis for state spatial planning and superordinate specifications for sectoral planning. State spatial planning gives concrete form at the state level to the federal principles of spatial planning, while at the local level, final planning goals are developed in compliance with both federal and state spatial planning specifications. It is the responsibility of local authorities to regulate the use of land for building and other purposes at the lowest planning level. (ARL, 2008).
The legal basis for planning in the countries is quite different - the example from Germany will show how complex only the basis framework is:
In general urban planning legislation articles include measures which seek to foster activities conducive to facilitating climate mitigation. The following outlines some measures taken from the German Building Code (BauGB) which was last amended in 2013.:
However, it is not possible to present and discuss all different legislation forms and contents of the different partner countries here. The following table shows some titles of the legal framework in partner countries.
Spatial planning has some basic principles which can be the following:
The specific objectives are:
Spatial planning is an area-related public sector task that can be subdivided into comprehensive (or overall) planning and sectoral planning. Comprehensive spatial planning addresses the supra-local (spatial planning) and local levels (urban land-use planning). The area related planning levels can be structured as follows:
While planning is legally, organisationally, and substantively defined and clearly differentiated, they are interlinked by the mutual feedback principle as well as complex requirements of notification, participation, coordination and compliance. The following figure shows the different planning levels (example Germany) and their mutual feedback principles.
Figure 1: Mutual feedback principle:
The following example will show parts of the planning systems in the different partner countries. (Source: ARL, 2008).
Supra Local Planning Levels
Spatial planning at the national and state levels comprises all comprehensive, supra-local and superordinate activities for structuring and developing space. It is “comprehensive” in the sense that it has the job of coordinating spatially significant sectoral planning. It is “supra-local” in that its scope is beyond that of the territorial and material, autonomous scope of the individual local authority. The comprehensive and supra-local nature of spatial planning gives it “superordinate” status in the planning system. (Source: ARL, 2008)
National/Federal Spatial Planning
The National / Federal Spatial Planning lays in general down the tasks and guidlines and principles of spatial planning, providing a framework for state/regional spatial planning acts.
For example in Germany the main aspects of national spatial planning include (Source: ARL, 2008):
In some other countries also sectoral acts are included (forests, nature, Rail…) for example in Hungary or Austria.
State Spatial Planning
State spatial planning works towards establishing and safeguarding equivalent and healthy living and working conditions in all parts of the state. Its main job is to lay down principles and binding goals in spatial structure plans, which are prepared on the basis of all spatially significant sectoral plans pertaining to industry and commerce, transport, utilities, housing, labour and recreation, as well as nature conservation and environmental protection. The most important tool in state spatial planning is the comprehensive, surpralocal, and intersectoral state spatial structure plan implementing federal planning principles, as well as state spatial development goals and ideas. The name given such plans varies from state to state. They are termed state development plan, state spatial planning programme, state development programme, etc. (Source: ARL, 2008).
Regional planning coordinates land use matters of supra-local interest transcending municipal boundaries. It defends the general interests of a region against the particular interests of local authorities. In Germany for example it has an independent, legitimate mandate - according to the Federal Spatial Planning Act – to (Source: ARL, 2008):
Local Land Use Planning
In the framework of local government planning autonomy, local authorities regulate urban development and the structure of their territories by means of urban land-use planning in their own responsibility. Local government urban land-use planning has the task of preparing and guiding the use of land for building and other purposes in the municipal territory. (Source: ARL, 2008). Task of the local urban development planning: to prepare construction and other use of land in a municipality in accordance with the Building Code and conduct.
In Germany for example exists a two-tier system of the local urban development planning:
1. Level: preparatory planning - preparatory land-use plan
2. Level: binding land use - binding land-use plan
The preparatory land-use plan outlines the development envisaged for the entire municipal territory. The territory of the municipality is not only the object of urban land-use planning and other local authority planning but also of supra-local, comprehensive spatial planning and regional planning. Supra-local plans are implemented and concretised through land-use plans adapted to the goals of spatial planning.
The preparatory land-use plan outlines the types of land uses envisaged for the entire municipal territory in accordance with the urban development proposed to meet the anticipated needs of the municipality. The particular importance of the preparatory land-use plan for urban development is that it sets out the fundamental decisions of a community on how and for what purposes (building, transport, agriculture, forestry, recreation, nature conservation, etc.) the land available can and should be beneficially and appropriately used. It provides the framework and basis for binding land-use plans. The aims of comprehensive spatial planning and of state spatial planning, in turn, provide the framework for the preparatory land-use plan.
Following tasks could be relevant for a preparatory land use plan:

Binding land-use plans are developed on the basis of preparatory land-use plans in the form of bye-laws, laying down binding specifications for urban development. These specifications are in turn the basis for measures required under the Building Code such as the provision of local public infrastructure (land improvement), land reallocation, and compensation. (Source: ARL, 2008)
The binding land-use is the second stage in the two-stage system of local urban development planning. In contrast to the preparatory land-use plan the binding land-use plan contains legally binding specifications steering and controlling urban development structures, the use of land for building and other purposes (Section 8 (1) of the Building Code). It is adopted in the form of a bye-law or municipal statute. The binding land-use plan is the chief instrument for implementing local government planning, and constitutes the basis for other measures needed to implement the Building Code. For example in Germany these include (Source: ARL, 2008):
The binding land-use plan gives specific form to the preparatory plan through the clear, plotby-plot definition of land use.
Aspects of the binding land-use plan
> focuses and differentiates the framework determinations of the preparatory land-use plan for spatially delimited areas
> lays down legally binding rules (inter alia)
- Type and level of building use,
- building height,
- building density,
- degree of building coverage
- spaces for transport and green spaces
> Decision as a statute by the local council,
> legally binding basis for the construction planning legality and the approval of construction projects in its scope,
> Determinations of the plan are mandatory for property owners.

Legal frameworks with relevance to the SPECIAL project have an impact on following issues:
1. Spatial structures in Cities/Regions and mobility.
3. Living and working environment.
For planners, there are manifold possibilities to influence the design of the built environment in a sustainable way. Below you will find some examples of energy efficiency in urban development:
a. possibilities of influence
Urban design allows influence on energy efficiency:
> orientation of the building
- main facade faces south to optimally exploit solar radiation energy
- deviations of up to 45 degrees are possible without large losses
> avoidance of shading
- avoid shading from other buildings or plants in order to optimally utilize solar radiation energy
- shading by trees: deciduous and coniferous trees are to be distinguished (in summer shading by deciduous trees can be quite intentional)
> compactness of the building
- geometry and compactness of the structure have a decisive influence on the demand of heating energy
- compactness follows from the ratio of length / depth / height. The lower the resulting ratio of surface to volume, the lower the annual heating demand.
- The roof shape influences the compactness and thus the heating demand (unfavorable roof shape: e.g. stacked storeys).
- Fragmented building subdivisions also have a negative effect on the ratio of surface to volume (e.g. forward/backward jumps, bay windows, dormers, building offset in row houses, etc.)
b. possible determinations in the binding land use plan (example German Building Code)
§ 9 Abs. 1 Building Code sets a closed list of legally binding rules – there is no possibility to invent other determinations.
> Impact on the energy efficiency can be caused by the determination of
- the type of development (open or closed) (§9 Abs.1 Nr. 2) → impact on compactness
- building lines and set-back lines (§9 Abs.1 Nr.2 in connection with § 23 BauNVO) → impact on orientation of the building, avoiding of shading
- the height of buildings (§9 Abs.1 Nr. 1) → impact on compactness, avoiding of shading
- planting orders (§ 9 Abs. 1 Nr. 25) → impact on avoiding of shading by plants
- exceptions to the admissible degree of building coverage to enable a better thermal insulation (§9 Abs. 1 Nr. 1 in connection with § 16 BauNVO)
- areas for plants and equipment for centralized and decentralized production, distribution, use, or storage of electricity or heating or cooling from renewable energy or combined heat and power generation (§ 9 Abs. 1 Nr. 12).
> Further possibilities are
- the designation of areas with local rules (bye-laws) on the compulsory connection to and use of a district heating system (§ 9 Abs. 1 Nr. 6) and
- when mounting a building or other constructions, special structural or technical measures for production, use or storage of electricity or heating or cooling from renewable energy or combined heat and power generation (§ 9 Abs. 1 Nr. 23b).
The binding land use plan does not give the possibility to determine the compulsory use of a certain energy source or an obligatory energy efficiency standard (e.g. by stating a maximum heat energy demand). The determinations according to § 9 Abs. 1 Building Code can only establish the conditions for energy efficient buildings or the use of renewable energies.
Further regulations, which are not possible via the Building Code, are governed by a contract if necessary.
- Urban development contract
- Real estate purchase contract
c. Possible regulations via contracts, e.g.:
- use of renewable energy, definition of certain energy sources,
- reduction of heat energy demand,
- improving energy efficiency,
- connection to heating network and/or use of CHP plants.
