ORA self-sufficient and sustainable home is one that does not depend on any renewable energy to meet household consumption. But if we want to live in a self-sufficient and sustainable home from an environmental point of view, it is also necessary that we carry out a series of actions that optimize the resources we consume and that reduce the impact of our daily actions on nature.
Sustainable self-sufficient homes
A self-sufficient home can also be ecological , that is, it takes advantage of natural resources such as the sun, water, wind or land, respecting the environment at all times, both during the construction of the home itself and once it is finished. . Its design must therefore be bioclimatic and environmentally friendly.
Currently there are already many buildings and houses that are built following a series of guidelines that take into account the factor of energy self-sufficiency and sustainability. Smart homes in which caring for the environment and the reduction in all its consumption prevail, generating new habits that future generations will inherit. These homes have the latest technologies to create, store and save energy, and thus reduce energy consumption by up to 70% in homes.
The facades of the houses of the future and home automation
Facades and home automation are two key factors that will play an important role in terms of energy savings, self-sufficiency and sustainability .
Facades are already playing an important role in the construction of new sustainable and intelligent buildings, since they contribute to energy production through the installation of solar panels and other materials that increase the production of clean energy.
In addition, there are various innovations in terms of construction that also help save on energy consumption . For example, there is a new construction technique that allows insulation to be installed on the external ventilated part of the façade, which achieves free circulation of air through its chamber and which implies energy savings of 40% compared to a traditional façade.
Secondly, home automation is a fundamental piece in the efficient use of energy within a house, while providing comfort and security to the people who live in that home. Home automation is the set of technologies applied to the control and intelligent automation of a home that allows communication between the user and the system.
Characteristics of a self-sufficient home
The less energy a home needs, the less installation is needed to make it self-sufficient. In addition, the houses of the future are also linked to the concept of an ecological home, because they will use energy from renewable sources.
Self -sufficient homes offer a series of common characteristics that define them, let’s see below some of the most important:
- Its design must follow the guidelines of bioclimatic architecture to make the most of existing natural resources with a lower energy input. Therefore, aspects such as orientation, winds, vegetation, etc. are very important.
- They use natural, sustainable or recycled materials for their construction .
- They are self-sufficient in electricity or thermal heating through solar panels.
- The orientation . The main facades must be oriented to the south to make the most of solar energy. In the northern part, the windows will be removed to maximize this effect and prevent heat loss in winter.
- The energy from non-renewable sources must be very low or zero , since they emit a large amount of CO 2 , a gas that is the main cause of the greenhouse effect.
- The visual impact on the environment must be minimal while trying not to alter the ecosystems that exist in the place where the house is going to be built.
- For the water supply , rainwater collection and utilization systems with natural purification will be used . For example, installing a roof with a V-shaped slope in order to collect all the rainwater that falls on it. From there the water is taken to a tank, where it can be made drinkable for consumption or used for irrigation work, or for showering, or for a swimming pool, etc.
In conclusion, we can say that renewable energies play a fundamental role in turning any home into a self-sufficient home . In addition to the aforementioned solar panels, a wind generator can also be installed, with solar collectors or a geothermal heat pump to provide hot water and heating in winter. If we add to this an air renewal and recirculation system that keeps the house at a perfect temperature without the need to open windows, the result will be a self-sufficient and sustainable home.
