How to plan a project as energy efficient as possible.
1. Choosing radiant foil heating
To heat the building, the system of radiant heating by electric folio “Cecather®”. Due to its efficiency, energy consumption is significantly reduced, allowing the temperature of each environment to be controlled independently according to needs. In addition, since there is no combustion, it is clean, safe and ecological. Another point to take into account among its advantages is the issue of the space it leaves free, since the panels are integrated into the floor, without heaters or radiators in sight.
On the other hand, any heating installation that is efficient must incorporate regulation and control to maintain ideal thermal conditions in air-conditioned areas, adjusting, at the same time, energy consumption to variations in thermal demand, as well as stopping the service when be necessary. The system “Cecather®” incorporates units of programmable timer-thermostats offering the possibility of turn the system on or off via Wi-Fi by independent zones, and can be activated from the place where the user is.
2. Choosing aerothermal pump centralized for ACS.
The aerothermal pump system is the combination of a heat pump and an accumulator that uses the heat from the air as a renewable source for the sole purpose of providing high comfort while reducing CO2 emissions is to extract thermal energy from the air that surrounds us. to use it effectively in the installations of DHW production. It is, therefore, a solution of great efficiency and performance. It is a renewable energy, included as such in the CTE (Technical Building Code). It is sustainable, and is classified as such by the European Union.
3. Choosing heat recovery.
The houses will have a system of heat recuperators which makes it possible to take advantage of a large part of the energy contained in the extract air, transferring it to the inlet air. In this way, it is possible to recover a very high percentage of the energy used for the air conditioning of the premises that would otherwise be wasted.
The air is introduced through the supply duct network to the bedrooms and dining room (in this way there will be two duct networks, one for air supply and the other for extraction). Air preheating occurs in the static heat exchanger located in the ventilation unit.
4. Choosing the photovoltaic system for self-consumption
Self-consumption is a generation scheme based on electricity production at the point of consumption. From a practical point of view, self-consumption allows users to control electricity production, consumption and significant savings.
The building will have panels photovoltaic for self-consumption, located on the roof, consisting of 30 400Wp photovoltaic modules distributed in two groups, with a resulting power of 12.00 kWp.
The use of this combination of thermal equipment, combined with constructive solutions (insulation on façades using the SATE System and roofs, suppression of thermal breaks, windows and special glass) has enabled the goal of high building efficiency to be achieved, reducing almost one 75% less heating than other conventional buildings of recent construction. But they will also get a reduction of CO2 emissions minimizing final energy consumption, thus achieving ten low energy homes.
