Dome structural design blocks high-angle summer sun

when it is hotter, and permits lower-angle sun in spring,

autumn, and winter when it is cooler.

Glazed Dome induces greenhouse effect to generate heat,

taking advantage of the high solar radiation levels on site.

Glazed panels are removed during summer months when

greenhouse effect is not desired and reinstalled in autumn

when temperatures begin to drop.

Thermal mass walls of superadobe construction store

heat during the day. Thermal lag allows it to naturally be

released later in the evening when it is needed most.

Pods are designed to induce stack effect to generate

desired air movement. In winter, heated air from the dome

enters during the day. In summer, mild air from outside

enters during the night.

Earth-sheltered and sunken below grade, each pod

makes use of stable soil temperatures, high performance

insulation, and ETFE glazing to minimize heat loss in spring

/ summer / autumn and heat gain in summer, stabilizing

interior temperatures.

In the driest and coldest times of year, an interior geothermal

pool and evaportranspiration of plants from the interior

garden add humidity. During summer, the pool is filled

with cool waters creating an evaporative cooling effect.
