The dome house design can optimize passive solar heating and cooling through the following techniques:
1. Orientation: Properly orient the dome house towards the sun with the majority of windows facing south in the Northern Hemisphere (or north in the Southern Hemisphere). This allows for maximum solar gain during the winter months and minimized solar gain during the summer months.
2. Thermal mass: Utilize materials with high thermal mass, such as concrete or earthen materials, in the construction of the dome house. These materials absorb and store heat during the day and release it slowly during the night, helping to regulate indoor temperatures.
3. Insulation: Properly insulate the dome house to minimize heat loss during colder months and heat gain during hotter months. This can include using insulation materials like foam, cellulose, or fiberglass in the walls, roof, and floor.
4. Windows: Install windows with high solar heat gain coefficients (SHGC) on the south-facing side to allow for maximum solar heat gain in the winter. Use shading devices like awnings, overhangs, or blinds to block out excessive sunlight during the summer.
5. Ventilation: Incorporate natural ventilation systems like operable windows, skylights, or vents to facilitate air movement and cooling. Design the dome house with windows placed strategically to take advantage of cross ventilation and create a chimney effect to naturally cool the interior.
6. Thermal chimney: Create a tall, well-insulated chimney in the center of the dome house that allows hot air to rise and escape. This creates natural convection currents inside the dome, removing hot air and replacing it with cooler air.
7. Vegetation: Consider planting deciduous trees or creating shading structures like pergolas or trellises on the south-facing side to provide shade during the summer months while allowing sunlight to enter during winter when leaves drop.
8. Proper overhangs: Design the dome house with appropriately sized roof overhangs or eaves to block out excessive sunlight during the summer when the sun is at a higher angle, while still allowing sunlight to penetrate during the winter months when the sun is at a lower angle.
9. Thermal windows: Install windows with double or triple glazing and low-emissivity coatings to minimize heat transfer and maintain comfortable indoor temperatures.
By incorporating these passive solar design principles into a dome house, it is possible to optimize the heating and cooling efficiency, reducing the reliance on mechanical systems and significantly decreasing energy consumption.
