LISI is a plus-energy home generating all its required energy electrically with a roof-mounted photovoltaic array. Thus excess energy, which is not immediately needed to operate the house, can be fed into the power-supply grid or stored to power electric vehicles. An optimized load management system, as found in LISI, can make an important contribution to the success of energy policy in the future.
