To build a net positive energy home that produces more energy than it consumes, you first need to minimize the building’s energy demand, and EPS cement sandwich wall panel is the best starting point. Its ultra-low thermal conductivity creates an extremely stable indoor temperature, so the house barely needs extra heating or cooling.

When the heat loss of the building is reduced to a very low level by EPS cement sandwich wall panel, a small set of rooftop solar panels can easily cover all the remaining energy demand. Many passive house projects using this panel have achieved net positive energy performance even in cold winter climates.

This combination of EPS cement sandwich wall panel and solar power creates a building that not only cuts utility bills to zero, but can even feed extra electricity back to the grid. It is one of the most practical paths to fully sustainable residential construction.
