Solar energy, low exergy, zero emission building concept
Renee Wansdronk

Seasonal solar heat storage
The building concept is characterized as a seasonal solar heat storage system, with the smallest exergy loss (low-exergy), and without any energy loss. In this case, exergy (applicability or quality of energy) stands for the temperatures which are used in the solar heating system, which are as close as possible to the demand temperatures (20 The building concept is characterized as a seasonal solar heat storage system, with the smallest ), and without any energy loss. In this case, exergy (applicability or quality
of energy) stands for the temperatures which are used in the solar heating system, which are as close as possible to the demand temperatures (20 ˚C indoor and 45 ˚C shower).

Local learn to deliver process
The project conditions are a southern facade for the solar collector, a water column in the core of the building, and a team being able to deliver the local design, construction and installation, and n a local learn to deliver process. Solar collector and storage cylinder The project conditions are a southen facade for the solar collector, a water column in the core of the building, and a team being able to deliver the local design, construction and installation, and willing to participate in a local learn to deliver process. Solar collector and storage cylinder suppliers, to deliver the installation elements, are available.

Infrared radiating cooling collector
The global floor area doubling in the coming decades, built on warmer continents, where indoor cooling is required, will impact global carbon emissions. A low-exergy infrared cooling collector avoids carbon emissions, by using space temperature instead of electricity. The collector cools water below air temperature, by means of an infrared radiator, surrounded by an infrared transparent insulator.

Redox flow electricity storage
To multiply the functionality of the seasonal solar heat storage and its required investments, the integration of a redox flow battery can be considered. Redox flow batteries perform better at higher electrolyte temperatures, requiring both membranes and electrolytes, able to operate at a 50-90 °C annual temperature curve for example.

Carbon credits blockchain wallet
Zero emission buildings need investments in solar heating and seasonal storage, which can be cofinanced by carbon credits. A blockchain carbon credits wallet for individuals is a small scale solution to facilitate this, house by house. The wallet may be used as a reliable carrier for alternative values as well, such as Sustainable Development Goal (SDG) values.

AR/VR/XR AI-avatar support
The building concept knowledge development, and its dissemination and implementation, will be supported by a virtual reality showing the design, by an augmented reality addressing its characteristics, and by an artificial intelligent multi-language avatar that both guides around and responds questions. Citizens and communities may be involved by an interactive map, to address potential locations.
