The widespread blackout that hit the Iberian Peninsula has highlighted the consequences of relying on conventional energy grids. The power outage left millions of homes in the dark for hours and caused enormous losses. Only self-sufficient homes were able to weather the consequences.
What are self-sufficient homes?
The design of these homes allows them to generate, store, and manage the energy they consume. That is their main characteristic, though not the only one.
These sustainable homes cover their lighting and heating needs by harnessing clean energy sources such as solar or wind. Also, they have systems to optimize water consumption and efficiently manage resources.
Self-sufficient homes, to this end, incorporate a whole series of essential facilities and elements:
• Solar panels or wind turbines for electric supply and lithium batteries for storage.
• Aerothermal or geothermal energy equipment for air conditioning.
• Passive natural ventilation and thermal insulation systems to prevent energy loss.
• Rainwater collection systems for domestic use. Even for drinking if there are purification mechanisms.
• Solid waste and wastewater management systems.
In addition, they often have other features, such as an orientation that allows for energy generation and reduced energy consumption, the use of natural materials, efficient appliances, and home automation systems.
Advantages of Self-Sufficient Homes
Self-sufficient homes have been gaining ground in recent years over traditional construction. Its advantages were demonstrated during the blackout that paralyzed Spain and Portugal.
Energy Independence
Having energy generation and storage systems, these homes do not depend on the electricity grid. The supply is stable, and comfort is not compromised.
Savings
Energy consumption decreases drastically. Although the initial investment in building autonomous homes is higher, this additional cost is offset in the medium term thanks to savings on energy bills.
Environmental Benefits
The use of clean energy helps reduce the carbon footprint. Meanwhile, natural and renewable materials in construction and water management systems decrease resource consumption.
Property Value Increase
There are cases where it is possible to adapt existing homes to make them self-sufficient, especially regarding energy generation systems and thermal insulation. This improvement increases the value of the property beyond the investment.
Other advantages of self-sufficient homes
Rising energy prices, events such as the blackout in Spain, and greater environmental awareness are leading self-sufficient homes to gain ground in the real estate market.
The development of new technologies is making it possible to increasingly adjust the cost of this type of housing. That is an added advantage, along with an increasing demand for sustainable construction, making it a promising investment opportunity.
