Smart Building as Power Plant - EnergyPLUS House with Energy Charge Management

摘要

The energyPLUS building is a role model example of integral planning and allows researching future orientated technology- and energy strategies today. It demonstrates an integral solution of appealing architecture, energy efficiency and optimal usage of solar power through photovoltaic. The goal is to achieve an intelligent power load management with an intrinsic power-usage share of 50% for the building's internal power consumers. To achieve this goal several measures were realized. By a backup-system of two batteries, the small-scale appliances get supplied in times at which the PV-System provides no power. Further surplus is fed into the public grid and drawn from it at times when the energy demand exceeds the PV energy yield. The plus-energy building is one answer to the challenge of increasing the share of renewable energies in the future energy supply.
