The construction of an autonomous energy-efficient house

For the construction of an autonomous energy-efficient house or also called “Smart Passive House”, several basic requirements must be met that allow the passive house to produce more electricity than it spends.

The main goals of the automatic system and the plus energy of the residential building are autonomy of the building, independent of external suppliers, a smart system that pays off over time and low consumption of electricity, water and gas.

The requirements are as follows:

1. Heating heat pump installation, which is combined with the hot water boiler system from PVT solar-photovoltaic panels on the roof or in the yard.
   Requirements: Solar-photovoltaic panels to cease operation if the capacity of the electricity storage system is exceeded and filled.
2. System for the use of energy from photovoltaics
   Requirements: Solar-photovoltaic (PVT) panels to cease operation if the capacity of the power storage system is exceeded and filled.
3. Ventilation system with decentralized recuperators
   Requirements: Recoverers to synchronize for simultaneous operation, as well as automatic and manual control.
4. Electricity storage system
   Requirements: The electricity storage system must have a large enough capacity to cover all the energy needs of the household.
5. Security system, access control and video surveillance
   Requirements: Access control can be carried out manually and through a smartphone application, through the integration of a smart video intercom system. Video surveillance to integrate with the smart system, allowing monitoring of the moment through an application, no matter where you are. Installation of additional protective components, as well as the installation of additional time relays, imitating presence and switching on in a chaotic principle the lighting in rooms, corridors, living room, kitchen, etc. at specified times, as well as integration with the included alarm system.
6. Automated sun protection system on windows and facade
   Requirements: Synchronization with a smart weather station, which allows the home to autonomously decide when it will be better to lower the sun protection system relative to the temperature outside and the position of the sun.
7. Low-energy LED lighting system with motion sensors and manual control

Main features of the project:
