A home that produces what it consumes.
ZeroEnergy is not a marketing term. It is a measurable engineering outcome: a home that produces at least as much energy as it uses over a full year. Soleta has been building to this standard since 2013 — when the concept was still considered experimental.
What ZeroEnergy means in practice
A ZeroEnergy home combines two things: a highly insulated, airtight building envelope that minimises demand, and renewable energy systems sized to meet that demand. The Soleta system achieves this through natural wood fibre insulation, triple-glazed windows, heat recovery ventilation and a renewable energy package tailored to the site.

Solar photovoltaic
Roof-integrated or ground-mounted PV array, sized to the home's annual consumption. Excess production fed to the grid or stored in battery.
Geothermal heating
Ground-source heat pump using the stable ground temperature (8–12°C across Northern Europe) as a heat source. COP of 4–5 — four to five units of heat for every unit of electricity consumed.
Solar thermal
Roof-mounted solar collectors for domestic hot water and space heating support. Reduces the load on the heat pump during spring and autumn.
Heat recovery ventilation
Mechanical ventilation with heat recovery (MVHR) — incoming fresh air is preheated by outgoing stale air. Efficiency above 90%. Essential for airtight buildings; eliminates condensation and maintains air quality.
Battery storage
Lithium-ion battery storage allows solar production to be used at night and during low-production periods. Sized to cover 2–3 days of average consumption.
Smart energy management
Integrated energy management system monitors production, consumption, grid import/export and indoor conditions in real time. Accessible via smartphone. Alerts for anomalies.
