Das IZW beteiligt sich an nationalen und internationalen Projekten. Nachfolgend sind die abgeschlossenen Vorhaben aufgeführt und beschrieben.
The main goal is to overcome still existing difficulties and barriers for the larger scale market in industrial applications. Industrial Heat Pumps (IHPs) offer various opportunities to all types of manufacturing processes and operations. They use waste process heat as the heat source, delivering heat at higher temperatures for use in industrial processes, heating or preheating, and industrial space heating and cooling. IHPs can significantly reduce fossil fuel consumption and GHG emissions in a variety of applications.

The Annex will start with a kick-off-meeting discussing and developing the detailed work programme, subdivided in the following tasks:
Task 1: Analysis of the collected Case studies and successful applications of industrial heat pumps,
Task 2: Structuring information on industrial heat pumps and preparation of guidelines
Task 3: Application of existing models for the integration of a heat pump into a process.
Task 4: Communication of the IHP potential for policy makers, designers and decision makers. Every task has its own Task Leader with specific competence for the specific Task, the work is coordinated under the overall management of the Operating Agent/Annex Manager. In this Task Managers Group the competences are brought together in both main areas, i.e. heat pump technology and industrial process integration of new technologies.
Germany (IZW e.V.) has been the Operating Agent. The other participating countries are Austria, Denmark, France, Japan, Switzerland and United Kingdom.
The following task-sharing activities were carried out by the participants:
Analysis of case studies / applications of IHPs
To select excellent application opportunities and success applications and approved examples.
To select a limited number of industries with large potential, focused on special areas with high product quality.
A heat pump data base to be used for the structuring the information of task 1 for each industry with best available technologies and best practices.
Models for a consistent integration of a heat pump into a process, e.g.
Arranging the information on heat pumping technologies for industry, for policymakers, industrial planers and designers, stake holders as well as heat pump manufacturers.
Providing a better understanding of the opportunities for the reduction of primary energy consumption, CO2-emissions as well as the economy of industrial processes.
Develop marketing and communication instruments and potentially support and advises on legislative.
A joint venture of the International Energy Agency (IEA) Implementing Agreements “Industrial Energy-Related Technologies and Systems” (IETS) and “Heat Pump Programme” (HPP).
The objective of the Annex was to reduce the use of energy and emissions of greenhouse gas emissions by the increased application of heat pumps in industry.

Communication strategy has to be developed (target groups, objectives and means) based upon learning curves by continuous consolidation of the created content through extensive monitoring of projects
The market potential of heat pumps for retrofitting existing buildings is much larger than in new buildings. However, the heat pump market in existing buildings today is small compared with the presently dominating market in new buildings. The new annex should therefore contribute to overcome the technical and market barriers in this interesting market sector.

The objective of annex is a survey of the availability, technology, economy, ecology and possible R&D trends of heat pump systems to retrofit low energy efficient space and tap water heating systems in existing residential buildings, taking into account that heat pumps are able to drastically reduce fossil energy consumption and the related greenhouse gas emissions. Space heating systems include first of all hydronic systems including heat sources, heat pumps and distribution systems but also air-to-air heat pump air-conditioners without heat distribution system. Heat pumps for retrofit should include electric heat pumps with zero or low GWP working fluids and gas-fired systems including ab- and adsorption.
Germany (IZW e.V.) has been the Operating Agent. The other participating countries are France and the Netherlands.
The objectives have been achieved by common studies performed by the participants for each country/organisation:
Statistical information on the present status of retrofitting of existing buildings in all participating countries and past and present R&D projects directly related to the objectives of the annex. An analysis of the present heat pump technology economically applicable for retrofit of existing buildings in the different climatic regions.
Development of a catalogue of existing buildings with already improved standard, insulation and medium temperature heat distribution systems applicable for the present generation of heat pumps (air-to-air-, air-to-water-, water-to-water and earth coupled heat pumps).
Collection and analysis of practical applications of heat pumps in existing buildings (case studies and demonstration projects).
Conditions of the development of new heat pump systems for retrofit applications should include
Heat sources include:
The task should include information on the economy and ecology (energy-efficiency and greenhouse gas emissions) of retrofit heat pump systems compared with conventional heating and cooling systems as well as governmental or utility promotion and support programmes. System optimising including heat source with given heat sink (distribution system).
