The construction of the first energy building residential zero of La Rioja by the use of geothermal and solar energy-based technology will begin in Alberite in the coming months. This innovative system, which dispenses with traditional such as natural gas, diesel or butane fuel, will allow users to save, at least 85% of the cost of your bill for heating, hot water and cooling. Also, is a truly environmentally friendly technology with environment, because that reduces by more than 85% the emission of CO2 into the atmosphere with respect to conventional systems.
This technology, already used in Europe for 30 years, and that Promotions Sádaba will now introduce in La Rioja, can be applied to all types of buildings: Residential (single family or community), centres (nurseries, schools, hospitals, residences for elderly...) or business (industrial buildings)(, blocks of offices...). After test its operation in the above-mentioned prototype, promotions Sádaba has everything ready to take the advantages of the energy of the Sun and the Earth to real buildings.
Constructed laboratory to test the system.
How the technology works
The operation of this system consists of the placement on the deck of the buildings in a pipe through which circulates water, which is heated by the action of the Sun and transported to the basement of the building. There, a circuit of tubes conserves energy through the Earth's capacity to accumulate heat.
Permanently, control computer system analyzes, through sensors, the needs of comfort of the building, estimated the necessary heat through a system of pipes of water circulating on the facade of the building, and ensure the interior temperature that the regulation sets as comfortable: between 20 and 24 degrees.
At the same time, these pipes create a thermal barrier that isolates the building, protecting it from leakage of temperature, both towards inside and towards the outside.
Advantages
This technology, based on energy sources solar and geothermal, but compatible with the rest of conventional energies, offers numerous advantages:
- Economic and environmental savings: reduces 85% the energy bill as emitted pollution, only energy consumption requiring is the corresponding to the electricity necessary to supply water circulation pumps, control mechanisms and temperature sensors. In addition, thermal barrier prevents the escape of heat where homes, offices or contiguous spaces are uninhabited. All of this, translated into numbers, represents an estimated savings of 70 euros a month for a House of 90 square meters
- Safer houses: there not to use fuels, in these homes is risk of explosion by poor combustion of boiler or gas leak.
- Stable prices: the system uses two clean, renewable, inexhaustible and free energy. For this reason, the owners of the buildings that use are protected before any crisis for the rise of the price or the depletion of energy such as oil or natural gas.
- Aesthetics: the temperature is constant throughout the year and was achieved by piping circulating on the façade, which is why in the interior of the houses, offices... There is no radiators. Thus, there is value in space to decorate and furnish.
The system employs two clean, renewable, inexhaustible and free energy.
