Following screenshot shows the available features that can be specified manually for calculation purpose.
The drawback of this application is that, the whole calculations are completely based on number of assumption and takes into consideration, only the basic information such as type of building and building location. The gbxml file format used by this application is only a geometric data of the 3D model and does not contain any information regarding the building materials. The application completely neglects the information regarding the building material properties, which is very important for evaluating the building performance. The building performance in terms of energy consumption, day lighting performance, thermal loads etc. is very much dependent upon the building materials used for construction. Thus, we can say this application provides an approximate result of the building performance based on the building geometry, building type and weather data obtained from local weather station. The application does have few design features which can be manually described, but still they are not sufficient enough to provide precise information required for the calculations.
