RoofKIT

Grid-friendly power grid operation in the context of inner-city re-densification

RoofKIT represents a comprehensive concept for energy-efficient renovation and expansion of existing buildings. PVT collectors serve as the heat source for a heat pump while simultaneously delivering solar power for the building. However, such rooftop additions lead to interactions with a cities’ existing power grid infrastructures. These aspects will be investigated experimentally by linking the RoofKIT building unit with KIT’s Energy Lab real-world laboratory. This will allow for developing viable solutions for energy management at both the building and grid levels. The experiments are conducted with actual residents in the building unit as well as the injection of power signals simulated from a Karlsruhe neighborhood.

fronTherm

A facade heating and cooling unit for the systematic retrofitting of existing buildings

fronTherm enables the simultaneous renovation of a building’s envelope and heating system. The concept is based on facade modules that contain a heat pump, a condenser surface on the inside for heat dissipation directly to the wall, and an evaporator surface on the outside facing the ambient air (heating mode). Suitably exposed facades are also equipped with PV. In cooling mode, the condenser surface becomes the evaporator surface and vice versa. Our tasks include the selection of suitable facade typologies based on an analysis of multi-family buildings of the German housing stock. For the selected facade typologies, various design, construction and building physics issues will then be solved.

C2CBridge 1 – Analysis and functional solution concepts
C2CBridge 2 – Testing and evaluation of the concepts

C2C explores how autonomous shuttle-based mobility can bridge the gap between urban public transport and rural individual travel. The project develops modular hubs where passengers can transfer conveniently to existing city transit, while the hubs may also provide additional services. A mock-up hub and test vehicles will be implemented for evaluation purposes on campus.
