Our story

Founded by architects and entrepreneurs David Palmer and Simon Whelan, FenestraPro has developed a suite of BIM software solutions to provide the tools and information needed to guide architects and other building design professionals in designing better performing building façades to meet their design intent.


FenestraPro’s software has quickly grown to become the most complete and sophisticated set of tools that a building designer can use to incorporate energy-efficient design principles from the earliest point in the design process through to the building design project. Easy-to-use and fully integrated within Revit, FenestraPro can read directly from the model and write the optimal design solution back to the model to automatically generate changes to the model.


FenestraPro for Revit guides on the optimization of the thermal, solar and daylighting requirements of the façade, and provides a detailed understanding of how key façade design decisions will affect the building’s performance to reduce energy consumption and improve occupant comfort.


FenestraPro’s leading design tools has attracted the attention of leading industry partners, including Autodesk, as well as top global architectural firms such as Gensler, Aecom and Skidmore Owens & Merrill.
