Net Zero Home: First Floor Concrete Pour

After building the foundation of this Net Zero home out of BuildBlock ICF, rebar and micro rebar poured into the concrete to increase strength and energy efficiency, the next step was to complete the first floor.

The floors will all have radiant floor heating, so installing hydronic piping through the concrete slab (in this case, in the central basement section) is one of the easiest and most efficient methods to complete it.  Once the pipes are placed along the floor, concrete is poured in to seal it. Warmboard® radiant floor heating boards will then cover open span trusses up to 39’ for the first and second floor creating an insulation rating of R-60.

This heating method is not only made possible by a renewable energy source, but it consumes less energy than traditional forced-air systems while providing the same amount of comfort.
