BIMergy Compound Windows Tool

Architects spend enough time coordinating documentation, modelling decisions, and compliance inputs. Energy rating should not add another layer of duplicated work. One of the things we’re building into BIMergy is the ability to turn Revit model information into useful NatHERS inputs, while also improving the everyday modelling workflow. A good example is our compound glazing tool. In Revit, architects often need to document grouped window arrangements, such as a fixed pane beside an awning window. These are visually and spatially linked, but for thermal simulation they still need to behave as individual glazing elements, each with its own system, U-value, SHGC, openable area, and window type. The compound glazing tool lets users assemble those WERS window combinations quickly, while BIMergy still breaks them back into the correct individual glazing units for schedules, and NatHERS assessment. So the benefit is not just “get a star rating”. It means: less duplicated data entry faster Revit setup cleaner glazing schedules fewer coordination errors better continuity between design intent, documentation, and assessment That’s the broader goal with BIMergy: not just compliance at the end of the process, but practical workflow improvements throughout the project. Energy modelling should feel connected to the way architects already work, not like a separate task bolted on later.
