In the thermal analysis of a building, a broad range of parameters enters the field defining aspect such as the properties of heat flows and materials, the efficiency of the heating system, the behavior of inhabitants.
Varying something in the project those parameters changes in such a way that can be counter-intuitive for the designer. Since small changes to a design can have large and unexpected effects on a building’s performance the possibility to have a continuous feedback is a great source of help.
Energy models realized with Grasshopper's plug-in Honeybee and Ladybug are able to quantify the overall energy consumption of the building through validated simulation engines like EnergyPlus, Radiance, Daysim and Openstudio. This tools are used to inform the designer in early stages of the design process.
