A zero-energy house consumes very little energy and produces all of it. Tiny House Design has an article about important things to think about when designing a zero energy small house. Here are some of the most important at keep in mind.
Heating, cooling, ventilation, and lighting are the most energy consuming parts of a typical house. That is where you can save most by being efficient.
Heating costs can be controlled in two ways: By using proper insulation and using efficient heating methods. If you insulate a house enough, the body heat of those living there could be enough to keep it warm. That is usually not how homes are built though. Therefore efficient heating is important. Heat pumps can save from around 50 percent of the heating costs.
Ventilation can be made more efficient if you heat the incoming cold air with the outgoing warm air. In summer you do the opposite. That way as little energy as possible is lost on ventilation.
For lighting, LEDs are the current best electric option. If you automate them only to activate when they are needed, much of the energy can be saved.
However much you do to minimize electricity consumption, you are likely to need some. If you put solar panels on the roof or a sunny spot in the garden, you can produce electricity yourself.
