IEA-TCP Graph: Visualization of all nodes and edges in the IEA-TCP data model

Size of the nodes corresponds to the number of connections, color to the type of node (see legend).

Combination of Methods used by TCP-Activities

A set of methods was developed to categorize the kind of project work that is done in the activities. The figure shows which methods are applied how often in total (node size), and which methods were frequently applied together (edge width) by activities. The color corresponds to the different method cate-gories described in chapter.

life cycle cost

Lines showing the smallest difference in life-cycle costs per non-renewable primary energy unit and HVAC configuration at office buildings in Stockholm (Sto), Stuttgart (Stu) and Rome. LCC includes investment, maintenance and operation over a 20-year period. HP stands for heat pump and DE for direct electric.

Solar district heating system with power-to-heat

District heating system with heat supply from central solar collectors, industrial waste heat, heating centre, heat pump, and with short-term and seasonal thermal storage. Source of the heat pump is the saisonal storage. Excess power from PV and wind turbines is used to operate the heat pump.

Solar heat in smart cities

List of the main advantages of solar heat: it is emission-free and 100% renewable, it increases the energy security, the price is affordable and remains stable for at least 20 years, it replaces imported fueld and provide new jobs.
