Engineering building performance
from facade to room.
hywin develops integrated facade and room systems that reduce energy use, improve comfort, and simplify building automation.
As standalone solutions or one connected system
in new build and retrofit.
We believe that energy efficiency
and comfort amplify each other.
CTF manages the facade. adaptIQ controls the room. Together, they work as one system.
One system
instead of many
Traditional buildings rely on separate systems for facade, HVAC, and control – creating interfaces, delays, and risk. hywin replaces this with one integrated system that manages thermal performance at the facade and control at the room level.
climatechfacade (CTF) handles heating, cooling, and shading directly in the facade. adaptIQ connects sensors, control, and operation – across rooms and buildings.
Fewer systems. Fewer interfaces. Better performance.
Built on proven expertise
As part of the owner-managed Alois Müller Group, hywin builds on decades of experience in energy systems, engineering, and real project delivery.
From concept to operation – delivered by one team
We’re a full-stack team: facade engineering, building physics, HVAC/hydronics, controls, commissioning, and operational reality—built to deliver projects, not just prototypes.
