Cooling strategies are different from heating strategies due to three reasons: First, cooling is already electricity powered for the majority of applications. Further, the cooling demand is much lower than the heating demand in the Northern Hemisphere. In addition it often overlaps the times of solar generation. Furthermore, the key innovation in the heating kit, heat pumps, also plays a central role in cooling since most heat pumps can be reversed to provide cooling. 5.2 Case studies7 shows the innovations in the cooling kit.
