Without a doubt, nowadays we all want our home to be efficient and sustainable. The commitment to satisfy our present needs without putting future needs at risk has permeated society. This commitment to sustainability and energy efficiency includes Modular Home. With our construction system prefabricated concrete homes. A system designed to achieve highly energy efficient and sustainable homes. This commitment to time means considerable savings for those who enjoy a sustainable home. What should a home have to be truly sustainable? There is an air conditioning system that is really efficient. Today we are going to approach both questions.
An efficient and sustainable home
The concept of sustainability is closely linked to savings. Enjoying a sustainable home is a guarantee of savings. A sustainable home must take advantage of the conditions of its environment. The orientation of the home is a decisive factor for sustainability. It will largely depend on the average climate of the area in which it is built. This must be a factor that must gain weight in future urban planning.
The design of the building is another key factor in achieving the goal of an efficient home. The building envelope largely determines its thermal and acoustic behavior. Energy losses must be taken into account due to open holes in the façade. Attention must be paid to the relationship between the surface of the envelope and that of the interior space of the home. Other factors that make our homes efficient and sustainable are:
- Adequate insulation of facades and roofs. Use of low emissivity glass.
- Adequate ventilation of the home. To avoid air leaks for example.
Aerothermal energy the efficient system
At the beginning we wondered about the existence of a truly efficient air conditioning system. The truth is that experience has shown that yes, there is a truly efficient and sustainable one, aerothermal. The operation of this system is based on air-water heat pumps. They generate heat without the need to use fossil fuels. They recover energy directly from the air. Air is a renewable energy source, as it is considered in a European Union Directive. The air is available twenty-four hours a day, it is constantly renewed. Without a doubt we are facing clean and sustainable energy.
How does this system work in a house? The system consists of a heat pump installed outside. This pump absorbs the energy contained in the air. Then there is another module, hydraulic, that emits the energy captured by the pump to the home's heating circuit. The advantages of this system over other more traditional ones are very numerous.
Aerothermal its advantages
One of the first and most obvious advantages of aerothermal energy compared to other traditional systems is the non-dependence on fossil fuels. Heat pumps run on electricity and do not require any other alternative energy source. On the other hand, traditional systems require a second source of energy. Another advantage is the maintenance of the system. Unlike other traditional systems, heat pumps do not have burners or combustion chambers. This simplifies maintenance, eliminating cleaning operations that other systems must perform.
Another undoubted advantage is the space that the system occupies. No greater than that of wall boilers, with the advantage of not requiring tanks to store fuel. But where aerothermal energy really wins by hand over the rest of traditional systems is without a doubt in its performance. The system, by recovering the free energy contained in the outside air, has performances greater than one hundred percent. The performance of a heat pump is measured by the COP. The different manufacturers indicate the COP of their machines, and with that information we have an approximate idea of their performance.
Thus, heat pumps that have a COP of four offer us performances close to four hundred percent. Which means that for every four kilowatts produced, only one will be reflected in our bill. The other three kilowatts are free, as they are recovered from outside air. We will not find this advantage in any traditional system. Well, they don't have that energy recovery function. Thus, the performance of traditional systems will never exceed one hundred percent.
Another of the great advantages of aerothermal energy is that you can enjoy three in one in your home. This system can serve three functions within your home. It can give us the heating we need, guarantee the supply of domestic hot water and cooling in hot seasons. We will have these three functionalities with the same system. We simplify installations and ensure the use of a system that allows us to save on these supplies.
