Bioclimatic architecture, living well and saving energy

Bioclimatic architecture is concerned with designing buildings taking advantage of available natural resources: sun, rain, wind, vegetation ... This way, energy consumption is saved and the environmental impact is reduced. By saving energy we save money and live more sustainably.

Bioclimatic architecture is the one that focuses on the design and construction of houses and buildings taking into account the climatic conditions of the place where it is being built, and also focuses on the use of available natural resources (sun, vegetation, rain , wind) to reduce as much as possible the environmental impact generated by construction and energy consumption.

Most architects prioritize design, aesthetics, but do not take into account such important aspects as the functionality of the building in relation to the environment and the use of materials, resources, etc. This type of design results in savings for everyone: for us and for the planet. Less CO2 emissions and less dependence on fossil fuels.

A bioclimatic home today can become totally sustainable: this increases the cost of construction a little, but in the long run it is profitable as it pays for itself.

In the case of having to consume external energy, these constructions have a production based on renewable energies, such as solar panels, for example.

We are then talking about:

Buildings 0 emissions: Thanks to the measures taken in construction and its renewable energy system, it is totally self-sufficient in energy matters, generating 0 CO2 emissions, and saving on energy consumption.

Energy plus buildings: Not only are they 0 emissions, but they generate surplus energy that they can sell. Regarding the materials used in bioclimatic construction, we find two:

  • Natural: such as bamboo, wood, earth, stone, etc.
  • Processed: like polystyrene, which is a great thermal insulator.

Another of the simple measures that can be taken and that is very effective, is the use of plants: strategically placed they protect from the cold of the wind, or offer shade in summer. They can grow on walls or ceilings (green roofs)

They also serve as a screen against noise and control erosion, in addition to beautifying the place where we put them. Bioclimatic architecture: designing buildings taking advantage of natural resources

How to build a bioclimatic home?

To get a home with these characteristics, there are several aspects to take into account such as:

  • Thermal insulation: thick walls, buried or semi-buried buildings; are some of the construction techniques used to achieve correct thermal insulation, which must retain heat or prevent its entry depending on the season of the year.
  • Cross ventilation: with the aim of creating good ventilation in all areas of the construction.
  • Integrate renewable energies, so as not to pollute or waste consuming fossil fuels when we need that energy.
  • Orientation of the construction, is designed taking into account the position of the sun to make the most of sunlight.
  • Sunlight and solar protection: at this point and depending on the region in which it is being built, the glass must have solar protection to reduce the entry of solar radiation.
  • Use as much as possible natural materials, and those that are most used in the region (they will be cheaper and it will be faster to obtain them).
  • Try to recycle all the waste that we can (organic waste, for example, into compost * for plants, or the shower water that we lose until it is heated, to use it for irrigation or scrubbing, etc.).
  • Look at the distribution of the holes in the house, and see if you want to build a patio, a cooling chimney, skylights ...
  • Exterior elements can be of great help, such as awnings or blinds, or pergolas ...
  • The color of both the ceilings and the walls also influences: the glades reflect the light and thus cool the spaces. The dark ones, on the other hand, for example on ceilings, absorb light and therefore heat.
  • A light roof versus a dark one reduces heat absorption by 50%. If we have a garden, opting for deciduous trees we take advantage of the fact that the sun slows down in summer but we can continue to enjoy the heat of the sun in winter.

In summary: the objective of bioclimatic architecture is to design constructions that are capable of changing their environmental behavior according to the conditions of each season of the year.
