House to the Beach consumes less energy than similar buildings of its type and size—both passively, through the green roof and buried facades, and actively, via geothermal wells. The above-ground gym’s walls are clad in continuous insulation, and its roof features a network of solar hot water panels. Large windows on the unburied facades, along with multi-level interconnected spaces, invite ample daylight into the buried portions of the building, reducing the need for artificial lighting. The entire lower-level façade opens up, and an exhaust system enhances natural ventilation, further reducing the need for air conditioning and improving indoor air quality.
