Energy efficiency through passive systems

In David Carrió we know that times are changing, climate change is already a reality, and we all have to provide solutions in this regard. That’s why, since the senior officials are beginning to impose that new buildings construction are built on the basis of energy consumption standards Minimum.

For this reason, we want you to be aware of the importance of building a home efficient, that is, having the right features and design for emit the minimum amount of CO2 to the atmosphere, and thus contribute to the climate change arrest.

To get that housing is efficient at different times of the year and can reduce bill of light equivalent to lowering C02 emissions, it is not enough have renewable energy facilities such as photovoltaics, aerothermal, geothermal or wind, but you have to design the house thinking in the situation of the terrain and in the elements that surround it.

Systems liabilities are mechanisms that are thought of in the design phase and executed in construction, but the most important thing is that they have no expense or maintenance in the Future.

Here are 5 systems liabilities to make a home efficient:

High thermal insulation

Isolation is a key aspect to save energy in the building. Increasing the thickness of thermal insulation reduces heat losses in winter and heat gains in summer. With a low thermal transmittance of exterior enclosures also lowers the demand for energy for air conditioning buildings.

Depending on the climate, the thickness of thermal insulation can be optimized until the inflection point, from which the increase in thickness is very little relevant to the improvement of energy efficiency taking into account the increase in cost.

Thermal envelope waterproofness

To ensure lower energy consumption, requires excellent sealing of the building envelope. Is important that a single airtight layer cover the entire building to avoid holes and airflows between the inside and outside through cracks and hollows.

Absence of thermal bridges

To ensure watertightness and thermal insulation, the removal of thermal bridges is rigorously controlled as they impair the energy efficiency of the constructive element.

Thermal bridges are places of geometry linear or point-in-time exterior enclosure where the energy flow is more large relative to the “normal” surface of the enclosure. You have to have a lot care when it comes to resolving the encounters of the walls of enclosures with carpentry, as well as the installation steps.

High performance windows and doors

The weakest areas of a building envelope are windows. That’s why it’s critical to have very high quality carpentry and glass in order to limit the maximum energy leakage through them.

A lot of attention has to be paid to its correct location and execution, using double or triple-glazed windows and also opt for low-emissive glass, i.e. one that reflects the heat interior of the house in winter, and keeps it outdoors in summer.

Mechanical ventilation with recovery Heat It consists of recovering much of the energy comes out, renewing the air used, of poor features hygienic, to pre-condition fresh air and get higher air quality.
