Intelligent building succeeds in meeting the comfort needs of building users, drastically reducing energy consumption by fulfilling efficiency measures, active and passive, to insulate and weatherproof buildings and to supply the buildings' lighting and energy needs.
All the energy demand, including heating, cooling and hot water, are covered with 100% renewable electricity (or direct renewable energies in existing buildings). The buildings consume the energy they produce. What is left is exchanged with the system, offering demand-side management services. In an Efficiency Scenario all these measures manage to save 80% in energy consumption compared to a BAU scenario.
Economic intelligence in this sector is essential. Profits should stop being linked to the sale of houses. Instead, profits should be linked to the supply of energy services offered by the building with the maximum efficiency.
