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.
