Based on global warming, decline of existing energy resources, exponential population growth, increasing geopolitical instabilities which are the result of uncertainty of the future energy supply, together with the fact that buildings represent about 40% of total energy consumption worldwide leads to a conclusion that a good architecture is not possible without a good energy concept.


    The buildings represent the bigger part of one of the biggest problem of our society - fair distribution of available resources. Therefore architecture can be a big part of the solution. Never before in the history of our civilization architecture had such a chance to gain one of the central roles in the society. Good architecture is always representing the expression of the cultural values, priorities and hopes of a society. Now it can produce a physical response for the existential challenges.


    A sustainable development by definition cannot get along with the decay in architectural quality of our built environment. A building with low architectural quality and good energy concept is not an actual benefit for a sustainable future. The objective of research and teaching at the Institute is the maximization of energy performance of buildings and cities, and the development of architectural and urban projects through form and structure optimization toward energy efficiency.

In the planning process of buildings an early and integrative planning guideline is required to

successfully implement Building-Integrated Photovoltaics (BIPV). Currently existing shortcomings are a lack of tools and a lack of a set of rules that can be easily applied in order to support

especially those planners at an early stage who are not experienced in PV.

VITALITY aims though at developing design rules and parameter areas for technically founded planning to be applied in exemplary use-cases with an urban context. Further, the influence of BIPV on further planning parameters of buildings (like thermal comfort, electrical yield) are evaluated. The usability and relevance for Building Information Modeling (BIM systems) will play an essential role in the project. According to the definitions of Climate Targets of the European Union (2009, 2011 and 2015) the

area-wide implementation of BIPV is a must. At the same time the European Building Directive foresees the compulsory implementation of BIPV or similar active energy generation measures. These

developments require strong efforts in terms of simplifying and enabling the consideration of BIPV in the planning process of buildings and urban districts.

The Austrian Technology Platform Photovoltaics (TPPV) has defined in its position paper 2014 the

integration of BIPV in the planning of new buildings as an important research topic and central

cornerstone to foster the Austrian BIPV market.


VITALITY addresses the elaboration of tools for an integrative planning process and offers

though an important step in the right direction. The results of the project are a set of numerical but simplified rules that allow a refined BIPV

planning already during the design process. The project analyses design criteria and

standardization and transforms them into

simplified models. Prototype buildings are planned in a parametric way, simulated in terms of thermal and light management, and they are examined with regard to their thermal, electrical

and BIPV expert planning. Planning interfaces and planning information flows are considered, and the relevance for BIM-systems is displayed.


As a result, the simplified models and

parametrical simulations lead to establish design rules for an early planning stage, respecting the typical needs of planners for both planning

flexibility and precision in terms of the expected BIPV-yield.
