Solvergy: Buildings application is designed to quickly analyze the energy status of buildings that consume energy for heating and maintain comfortable indoor conditions. The application allows you to determine the energy class of the building, the average and maximum consumed thermal power of the building, as well as the level of thermal energy consumption by the building throughout the year. In addition to the “Constructor” mode, which allows you to create a model of building walling in a graphical editor using appropriate templates for the composition of building wallings, there is an “Express” innovative mode, which, using artificial intelligence, allows you to evaluate the energy class and characteristics of a building within a few minutes. The calculations are based on European regulatory documents and standards for calculating the thermal characteristics of a building.
