Residental Solar Greenhouse Design
You may ask "Aren't all Greenhouses Solar" ..... well... yes, sort of. A Solar greenhouse uses energy very efficiently; relying on mass to store heat during the day and then release it in the evenings as the interior temps cool. Generally, a solar greenhouse will cost a fraction of what a normal greenhouse costs to heat it.

Basic Principles of Solar Greenhouse Design
|  | |
All greenhouses collect solar energy. Solar greenhouses are designed not only to collect solar energy during sunny days but also to store heat for use at night or during periods when it is cloudy. They can either stand alone or be attached to houses or barns. A solar greenhouse may be an underground pit, a shed-type structure, or a quonset hut. Large-scale producers use free-standing solar greenhouses, while attached structures are primarily used by home-scale growers.
Passive solar greenhouses are often good choices for small growers, because they are a cost-efficient way for farmers to extend the growing season. In colder climates or in areas with long periods of cloudy weather, solar heating may need to be supplemented with a gas or electric heating system to protect plants against extreme cold. Active solar greenhouses use supplemental energy to move solar heated air or water from storage or collection areas to other regions of the greenhouse. Use of solar electric (photovoltaic) heating systems for greenhouses is not cost-effective unless you are producing high-value crops.

Bubble Insulated Greenhouse
Kat and Ross Elliott live about 20 minutes northwest of Perth Ontario Canada in the beautiful Tay valley area. They decided about three years ago that they wanted to build a special 1500 square foot greenhouse that would demonstrate that in the cold climates of Canada a greenhouse would not have to be a carbon dioxide user like the traditional greenhouses around the world
Now they have their soap bubble insulated greenhouse up and running. Kat is busy growing organically grown tomatoes, kale, herbs and green veggies year round for herself and Ross as well as for a retail outlet.

Designing & Building A Solar Greenhouse or Sunspace
Solar greenhouses and sunspaces remain a popular design for both new and existing homes. They can produce heat, provide an environment for intensive food production, and offer a very pleasant living space. However, a greenhouse or sunspace can seldom do all three things well. Consequently one of the most Important first steps in designing and budding a solar greenhouse or sunspace is to develop a very clear idea of the purpose of the space.

Greenhouse Energy Conservation
With the price of energy getting more expensive I am hearing from many greenhouse gardeners wondering how to use less energy or how they can benefit from more solar heating. The following is a discussion that should help guide you down the road towards less heating needs
These are the basic requirements for an energy conserving or solar heated greenhouse. Even if you have a conventionally heated greenhouse, you can still reduce the need for heat and reduce your heating bills by applying some of these basics for higher energy efficiency.

Growing Spaces Geodesic Greenhouse Kits
Growing Dome Greenhouses, tried and tested in the Rocky Mountains, allow you to grow fresh vegetables, flowers, fruit and herbs year round, with minimal extra heating or cooling.
Because of its unique solar design and seven features it is the most energy-efficient, hobby greenhouse kit available today.

Heat From The Earth
|  | |
He bills himself as "Nebraska's Largest Citrus Grower", an unusual title given Nebraska's notoriously cold winters and relatively short summer growing season. But what started out as an interest in earth heating for a new home has evolved into a semi-tropical biosphere in the western panhandle of Nebraska.
Russel Finch developed an interest in earth heat in 1979, when he was planning the heating system for an A-frame house he was about to build. He wanted to use a heat pump as the only source of heating and cooling but found that heat pumps were not suitable for northern areas unless an additional electric heat unit was used. At that time, heat pumps lost their efficiency at 32 degrees F, the temperature at which they switched over to electric.
However, Russel knew that throughout most of the United States, the temperature is stable at 52 degrees F at eight feet below ground. He reasoned that if a heat pump was in a small room, and air that had passed through tubes buried eight feet deep was blown through that room, the heat pump would behave as if it were in a southern climate. Russel contacted the University of Nebraska to validate his thought process, and was told by two professors that the idea was not feasible.

Solar Bubble Build
The Solarbubblebuild is the first operational building of its kind in Europe. It is one of a handful of uniquely sustainable buildings around the world that makes use of interior-environment control systems commonly know as Solaroof technology.
To the lay observer, the most distinguishing feature of a Solaroof building would most likely be the use of liquid bubbles to create insulation. When required, a mass of soap bubbles are held between two transparent skins that form the roof and walls of a Solaroof building to provide a thick transparent blanket of insulation or cooling shading. There are other integral components and processes working within the building, but for anyone meeting with the project for the first time, the bubbles must be the most exciting and memorable element. Thus the name of my own project was arrived at with this thought in mind.
