It is also more specifically used (particularly in Germany) to describe a building design with two structural layers or a building within a building.

−	These buildings are based on the principles of a trombe wall or a winter garden, as a high proportion of the second structural envelope is often transparent, so the air between it and the internal building remains warm. This means the internal building is not exposed to the temperature differences of the outside or ~~exposed~~ to the elements, so can be built with lower levels of insulation, air tightness and weather protection.	+	These buildings are based on the principles of a trombe wall or a winter garden, as a high proportion of the second structural envelope is often transparent, so the air between it and the internal building remains warm.

−	The term bio-solar roof describes roofing solution that combines energy generation through the installation of photovoltaic panels ~~along~~ with an intensive or extensive green roof. Apart from the known benefits of green ~~roofssuch~~ as reducing urban heat island effect, water retention and ~~biodversity~~, bio-solar roofs can be beneficial to the efficiency of photovoltaic panels because many run most efficiently when the ambient temperature is around 25 degrees. A biosolar roof can help keep ambient temperatures lower than with a standard black or white roof construction, with some studies estimating a increase of around 1% in the electricity generating potential ~~of the solar system~~.	+	The term bio-solar roof describes a roofing solution that combines energy generation through the installation of photovoltaic panels, with an intensive or extensive green roof.
