Active climate façades for sustainable construction
Controlled natural ventilation (CNV) using mechanically operated windows ensures air can be exchanged automatically using natural resources such as wind and thermal airflows. The unobtrusive electromechanical drives open and close windows and roof lights completely automatically. This keeps indoor spaces fresh, and at a comfortable temperature, and provides effective cooling at night in summer, whilst significantly reducing energy costs and all for a relatively low initial investment.
D+H is among the world market leaders for CNV. As a system supplier we can provide you with complete ventilation systems, complete with drives, control units and sensor systems. Our controlled natural ventilation solutions are based on pioneering technologies which are designed to save both costs and energy. This makes them ideally suited to the stringent demands of sustainable construction projects.
