REHABILITATION AND RENEWABLE ENERGYGeothermal energy
Geothermal energy begins to have a boom as an alternative to traditional sources of thermal energy, thanks to the support provided to this type of renewable energy to be included in the aid programs for the rehabilitation of buildings and communities of owners. This is laid down in the aid program for ergy refurbishment of existing buildings in the residential sector (use housing and hotel) (PAREER) in which, when the rehabilitation of buildings and communities contemplate actions aimed at improving energy efficiency the thermal envelope (walls and roofs) or heating systems (replacement of conventional energy from biomass or geothermal energy) and Geothermal energy neighboring communities and building owners will benefit from a series of grants, as long as they improve the energy rating of the building or community in at least one letter in such rehabilitation.
The type of assistance they are entitled owners of residential buildings, owners and owners of houses, depending on the type of action that will take place.
Many are asking: What is geothermal energy? Well we hope to clarify this doubt. Geothermal energy is a technology that takes advantage of the heat energy from inside the earth’s crust for use in the operation of heating, cooling and domestic hot water installed in buildings, homes and communities of owners. The system requires a gauge of heat energy, which takes heat from the inner bark in winter and dissipates in summer and a heat pump energy reversible. For there to be a uniform distribution of energy be required radiating surfaces in the floor, ceiling or walls where circulate hot water in winter and cool in summer.
Geothermal energy as an energy source can be used in both heating and cooling and domestic hot water. The main advantages of geothermal energy are the renewable nature, since from 15 meters deep crustal remains more or less constant over the whole year temperature, which allows it to be used both in summer ( cooling) and winter (heating). Below 20 m. the temperature inside the crust increases about 3 degrees every 100 meters and the supposed benefit of geothermal energy for the environment since her CO2 emissions and primary energy consumption are reduced.
By contrast, the initial cost of geothermal energy facilities may be somewhat high, but the savings in relation to the use of other energy sources, causes, depending on the actual consumption, the payback period of the installation can be reduced two or three years (the higher consumption, higher savings so the payback period of the installation of geothermal energy is reduced).
