Energy Block Home in Sisters, Oregon

Redefining Energy Efficient Sustainable Building

SunTerra EnergyBlockTM provides an interior decorative masonry wall surface utilizing the principle of thermal mass to create an even temperature throughout a home year-round. The thermal mass absorbs heat energy when the surroundings are higher in temperature than the mass and gives thermal energy back when the surroundings are cooler. This produces the most efficient and comfortable living environment available for the homeowners.
