We are developing an software that will be based on much simplified parameters (unlike other similar programs, which are much too complicated for everyday use) to display through which segments of the building most energy and money is lost and optimal product recommendations for reducing energy consumption. The purpose of the application is so user awareness about the wastefulness of their facilities and their options for the best decision for action, which will entail the reduction of emissions and energy savings, as well as costs. Link to the existing prototype application, which is currently still very grave and he is still missing quite functions, such as the calculation of CO2 and CO2 savings, the possible rehabilitation facility, etc..
