Our first full-scale prototype is heating and cooling a house in Princeton, NJ

This house in Princeton has been kept comfortable with Zeroth since July 2023. It is connected to the central air handling unit and controlled by the house thermostat, like any other heat pump. The customer-facing product will be fully redesigned and made more compact.

The renewable energy age calls for a new climate control paradigm

Indoor comfort in buildings represents 20% of global energy usage, and is growing as the world becomes warmer and more urban. Natural and non-mechanical solutions have existed for decades in architecture but have been limited to an experimental or high-end design niche. Zeroth’s long-term mission is to make these solutions accessible to everyone by offering them as products that are qualitative, reliable and contemporary.
