The world of bioclimatic architecture is on the rise, it is extends to professionals in the sector who see a job or training opportunity that is really interesting. We were wondering what tools we can start to show you and that due to its usefulness and simplicity as well as being free can provide us with different benefits both in knowledge and application in our projects.
In this case, as a result of the previous post “Manual of bioclimatic design for urbanism” We have been investigating in favor of its creators and we have come across a tool that we believe is worth knowing, SCBcal-01 calculation tool (Certification of Bioclimatic Solutions) that comes from the BIOURB Project (Diversity cross-border bioconstruction, bioclimatic building and its adaptation to modern architecture and urbanism) that comes from of a cross-border cooperation program between Spain - Portugal supported by the European Union and co-financed by the FEDER and POCTEP.
The application object is for calculation and pre-sizing of its contribution to the reduction of the energy demand of buildings in addition to allow an estimate of the contribution to the reduction of CO2 emissions. Here we could say that for that already we have the "magnificent" programs provided by the Ministry of Industry for energy certification, since partly yes and partly no.
The SCBcal-01 tool focuses on a assists the designer in determining the size definitive of a bioclimatic solution that is desired incorporate into a building. To do this, he works on a series of concrete constructive solutions, which are:

They are known by the name of “Trombe Wall” those bioclimatic solutions that incorporate a vertical enclosure opaque, with variable thickness and transmittance, on its face interior and a glazed enclosure, simple or multiple, in its outer face.
A variant of the trombe wall is the “ventilated trombe wall”. It is an enclosure for solar capture, with the typical characteristics of a trombe wall, which also It has some ducts (with natural or forced ventilation) that allow the possibility of a double air exchange
It is considered that there is a gallery (or greenhouse) attached to a building when a relatively large building volume closed, partially or fully glazed, is located sharing, on its exterior side, one or more enclosures verticals of the building.
The function of a passive collector cover is to capture the maximum amount of solar radiation possible during the period of heating. This also supposes an extra consumption during the cooling period, which can be decreased by transition spaces located below deck. these spaces must have the maximum possible insulation in winter with with respect to the outside, with the ability to be ventilated in summer to lower its temperatures.
This solution consists of interposing an element vegetation between solar radiation and the enclosing wall of the building, thus preventing a significant part of the radiation impinges on the wall and avoiding the entry of heat towards the inside the building due to this phenomenon.
The vegetative cover or green roof of inertia on a building produces insulation and thermal inertia effects, which depend fundamentally on the height and characteristics of the vegetal substrate and the rest of the lower layers, an effect of shade (linked to evapotranspiration and photosynthesis), depending on the type and distribution of plants used, and a reduction in the outside surface temperature due to direct evaporation of water present in the substrate. Nails suitable seasonality characteristics of these plants could contribute to an improvement in their behavior energetic. It is interesting to have plants with a wide summer development and little winter activity, preferably leafy expires.
The passage of building ventilation air through underground elements (ducts or cellars) allows a tempering it before entering the building. of this This way energy savings are achieved both in winter (for heating of the air) as in summer (by cooling). In addition, the alternative use of both options through a same heat exchanger can help regeneration ground temperature at sufficiently deep distances.
