Winter Heating | Summer Cooling
The Growing Dome® year-round greenhouses differ from ordinary greenhouses in that they utilize a combination of innovative systems to harvest solar energy for both heating and cooling. These passive solar greenhouses are designed to accommodate heat-loving plants in the summer and cold-hardy crops in the winter with no or little need for heating or cooling (depending on the climate). Our value of “living lightly on the earth” is reflected in how efficient and simple each and every system in the Growing Dome is. We encourage and support minimal use of fossil fuels with this clever design as well as have systems that are dual purpose, providing heating benefits in the winter and cooling in the summer. Nothing is wasted in these beautiful structures.
In the winter, the Growing Spaces geodesic dome greenhouse is designed to capture and store the heat of the sun during the day and slow down the heat loss overnight. The following is an overview of this principle in action:
Capturing Heat During the Day
We are still the ONLY greenhouse kit manufacturer that offers an above ground pond as part of the kit.
Preventing Heat Loss at Night
With these unique systems and the geodesic dome greenhouse design we create a structure that allows cool weather plants to continue to grow throughout snowy, cold winters. In very cold or cloudy climates the solar energy can be augmented with the use of a small greenhouse heater, which can be thermostatically controlled. We calculate that Growing Spaces greenhouse kits need only 1/3 of the amount of heat required by conventional green houses. To learn more about auxiliary heating methods please visit our Greenhouse Heating Options page.
COOLING THE SOLAR GREENHOUSE:
In the summer ALL greenhouses from hoop houses to traditional glass houses to rectangular commercial greenhouses have the potential to overheat. Most commercial and hobby greenhouses have either a ceiling fan or an exhaust fan to cool the structure. This can be result in high energy bills and intensive fossil fuel use. The Growing Spaces Growing Dome, however, uses sustainable methods of cooling which are passive or solar powered.
