Certification of Bioclimatic Solutions. Bioclimatic calculation tool SCBcal-01
The world of bioclimatic architecture is on the rise, it is spread by professionals in the sector who see a job or training opportunity that is really interesting. We wondered what tools we can start to show you and that due to their usefulness and simplicity, as well as being free, they can provide us with different benefits both in terms of 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 (Cross-border bioconstructive diversity, bioclimatic building and its adaptation to modern architecture and urbanism) that comes from a cross-border cooperation program between Spain - Portugal protected by the European Union and co-financed by the ERDF and POCTEP.
The purpose of the application is to calculate and estimate its contribution to reducing energy demand in buildings, as well as allowing an estimate of the contribution to reducing CO2 emissions. Here we could say that for that we already have the "magnificent" programs provided by the Ministry of Industry for energy certification, partly yes and partly no.
The SCBcal-01 tool focuses on helping the designer in determining the final size of a bioclimatic solution to be incorporated into a building. To do this, it works on a series of concrete constructive solutions, which are:
Non-ventilated trombe walls
Bioclimatic solutions that incorporate an opaque vertical enclosure, with variable thickness and transmittance, on their inner face and a single or multiple glazed enclosure, on their outer face, are known by the name of "Muro Trombe".
Ventilated trombe walls
A variant of the trombe wall is the "Ventilated trombe wall". It is an enclosure intended for solar capture, with the typical characteristics of a trombe wall, which also has ducts (with natural or forced ventilation) that allow the possibility of a double air exchange
Bioclimatic galleries
It is considered that there is a gallery (or greenhouse) attached to a building when a relatively closed construction volume, partially or totally glazed, is sharing, on its outer side, one or more vertical walls of the building.
Passive pickup covers
The function of a passive collector cover is to capture as much solar radiation as possible during the heating period. This also supposes an extra consumption during the cooling period, which can be reduced by means of transition spaces located under cover. These spaces must have as much insulation as possible in winter with respect to the outside, with the ability to be ventilated in summer to lower their temperatures.
Green walls
This solution consists of the interposition of a vegetal element between the solar irradiation and the enclosure wall of the building, thus avoiding that a significant part of the radiation falls on the wall and avoiding the entry of heat into the building due to this phenomenon. .
Vegetable covers
The green inertial roof or green roof on a building produces thermal insulation and inertia effects, which depend fundamentally on the height and characteristics of the plant substrate and the rest of the lower layers, a shadow effect (together with evapotranspiration and photosynthesis), depending on the type and distribution of the plants used, and a reduction in the external surface temperature by direct evaporation of the water present in the substrate. Adequate seasonal characteristics of these plants could contribute to an improvement in their energy performance. It is interesting to have plants with extensive summer development and little winter activity, preferably deciduous.
Geothermal ventilation
The passage of building ventilation air through underground elements (ducts or warehouses) allows it to be tempered before entering the building. In this way, energy savings are achieved both in winter (by heating the air) and in summer (by cooling). In addition, the alternative use of both options through the same heat exchanger can help the thermal regeneration of the ground at sufficiently deep distances.
