9.5.3 Land Use and Building Development Planning
Land use and building development planning sets out legally binding conditions for
all subsequent planning and development processes. Here is where building types,
building heights and their orographic alignment are decided. Special Conditions
also determine a number of UHI measures at this stage. Aside from building alignments and size, rules may be defi ned to determine the amount of green space on a
given parcel of land, as well as the size and location if windows. Details on roof and
façade greening may also be provided at this point.
9.5.4 Planning and Development of Public Green and Open
Space
Planning and development of public streets, squares, green and open spaces is vital
for the implementation of UHI-reducing measures, because here is where qualities
are determined for the long term. Major emphasis is placed on incorporating UHIsensitive criteria into design competitions. Internal guidelines and checklists, some
of which contain climate-sensitive aspects, facilitate implementation of measures at
this level.
9.5.5 Developer Competitions, Housing Initiatives and Public
Housing Construction
Approximately 60 % of households in Vienna live in subsidised apartments
(Kolbitsch and Stalf-Lenhardt 2008 ). This level of action is therefore relevant for
many parts of the city. Developer competitions have proven successful in Vienna
since 1995. The competitions help to promote quality in subsidised apartments.
Four main criteria are used to assess the quality of drafts: architecture, economy,
ecology and social sustainability. In addition there are “theme” competitions for
low-energy and passive houses or car-free housing developments. Competitions to
date have considered microclimate for the design of open spaces and have also
included the vision of “climate neutral cities” (e.g. Aspern Urban Lakeside).
The housing initiative launched in 2011 has contributed to ensuring quality based
on a two-tier cooperative planning process. Both programmes have always emphasised climate protection but have not paid much attention to adaptations to climate
change. Evaluation of these instruments (Liske 2008 ) shows that new and quite
specifi c topics can be integrated into urban development at this level and turned into
pilot projects for other projects to copy.
