The Institute has also created a corresponding calculation software which calculates the energy demand of buildings, including the savings potential. The software not only analyses the building shell but also takes into consideration air conditioning, heating and lighting. This comprehensive approach makes the model particularly useful when designing new buildings and is compelling when compared to evaluation models that analyse individual measures.
The Fraunhofer calculation tool can be adapted for multipurpose buildings in India. It also offers advantages when compared to complex simulation models: it delivers robust, comparable results and enables easy handling, making it well suited for application as a broad-based promotional programme as well.
The model is now being adapted to the conditions in India in cooperation with "The Energy and Resources Institute" (TERI). KfW Entwicklungsbank is supporting this adaptation process which involves supplementing the German model with specific data from India - such as on facility technologies, building materials or user behaviour. The adapted model will then be used as part of a housing energy efficiency programme. Later the programme is to be expanded and applied to commercial and public multipurpose buildings in the framework of a promotional programme.
Claudia Loy, the Division Chief responsible for this area at KfW, describes the cooperation between the German and Indian research institutes as "promising and forward-looking" because such innovative cooperative arrangements create the foundation for transferring proven promotional programmes, thereby allowing "quantum jumps" in the common fight against climate change. Both the International Energy Agency and the American Government have already drawn on the experiences of the Fraunhofer Institute to calculate the energy balance of buildings. However, bilateral cooperation for transferring energy balance software has thus far not yet existed in this form.
