COMMERCIAL WINDOW ACTUATION

Window actuators selected around the opening and the required operation.

Actuator selection determines more than whether a window opens. EBSA considers opening geometry, sash size and load, required stroke and opening angle, operating and closing forces, speed, synchronisation, mounting, feedback and the way the opening must behave within the wider facade system.

Working across the D+H Mechatronic drive range, EBSA develops actuation around commercial project requirements — from individual automated openings to large coordinated facade systems using multiple drive types and control architectures.

The actuator follows the opening. The opening should not have to be redesigned around a convenient motor.

ACTUATOR SELECTION

The actuator follows the window geometry — not the other way around.

A suitable actuator has to move the opening through the required geometry, achieve the intended open position, close the element correctly and operate consistently within the control strategy. That requires more than matching a nominal force rating to a sash.

EBSA considers the complete opening condition — including dimensions, weight, hinge or pivot arrangement, seals, brackets, available mounting space, environmental exposure, required operating behaviour and the relationship between the actuator and the control system.

02

STROKE + OPENING

Determine the actuator travel and geometry needed to achieve the required opening without treating nominal stroke as the only design parameter.

03

Consider operating loads, closing behaviour, seals and the forces created through the actual bracket and window geometry.

04

SPEED + ACOUSTICS

Match operating speed and noise expectations to the building use and required sequence.

05

MOUNTING + ACCESS

Resolve brackets, structure, clearances, cable routes and future access before the installation becomes difficult to service.

06

SAFETY + USER INTERACTION

Consider the way people may interact with the opening and the operating strategy appropriate to the application.

Actuator selection is the result of the opening geometry and operating requirement, not the starting point.

CHAIN ACTUATORS

Compact actuation across a wide range of commercial window applications.

Chain actuators are widely used where the project needs a compact drive that can be integrated cleanly with the window or facade system. Final selection depends on the opening geometry, actuator position, stroke, force, speed, control requirement and whether one or multiple drives are needed.

Current D+H chain-drive families used across EBSA window-automation applications include VCD, CDC, KA, CDM and CDP. These families provide different pathways through compact, standard, higher-capability and specialist chain-drive requirements; the correct family is selected after the opening and system requirements are understood.

RACK + PINION ACTUATORS

Linear drive solutions for demanding opening geometries.

Rack-and-pinion actuation provides a robust linear-drive pathway for commercial facade elements where the opening condition calls for longer travel, higher operating forces or a drive form better suited to the installation than a chain actuator.

Current D+H pathways include ZA and DXD families. As with chain drives, selection depends on the complete opening and control requirement rather than the actuator family name alone.

LOUVRE DRIVES

Operable louvres require coordinated movement through a louvre mechanism rather than simply pushing or pulling a sash. D+H LD drive technology provides a dedicated pathway for applicable automated-louvre systems, with the complete solution coordinated around the louvre mechanism, geometry, control requirement and facade application.

SPECIALIST DRIVES

Some facade elements require dedicated locking, side-hung, door-opening, rooflight or other specialist drive arrangements. EBSA assesses these applications around the actual movement, loads, interfaces and maintenance requirements rather than forcing them into a standard window-actuator solution.

OTHER SPECIALIST MOVEMENT

The drive type changes with the opening. The engineering principles do not.

COORDINATED MOVEMENT

Large and complex openings may need more than one drive.

Window width, stiffness, load distribution, sealing and the required movement can make a multi-drive arrangement more appropriate than a single actuator. In those applications, drive quantity and position, mechanical loading, synchronisation, control architecture and commissioning need to be considered together.

EBSA develops multi-drive openings as one operating element rather than treating each actuator as an independent motor. Depending on the selected D+H family and control architecture, suitable synchronised or addressed drive technologies can support coordinated movement, configuration, status and diagnostic functions.

Adding actuators is not the same as engineering a multi-drive opening.

COORDINATED MOVEMENT → CONTROL ARCHITECTURE

ACTUATION + CONTROLS

The actuator is one part of the operating system.

Drive selection affects the electrical load, power supply, wiring, grouping, feedback and control functions that sit behind the opening. The control architecture in turn determines how the actuator is commanded, monitored and coordinated with other openings and building systems.

Depending on the selected actuator and system architecture, D+H technologies can support functions such as synchronised operation, configuration, position or status information and diagnostics. EBSA considers those requirements during actuator selection rather than treating controls as a separate decision after the hardware has been chosen.

WINDOW ACTUATORS IN PRACTICE

Different openings require different actuation strategies.

Project scale alone does not determine actuator selection. EBSA’s project work ranges from large repeatable facade systems to specialist openings where geometry, drive arrangement or control behaviour demands a different solution.

FEATURED PROJECT

ATLASSIAN CENTRAL — SYDNEY

Thousands of actuators coordinated across stacked habitat zones.

Across Atlassian Central’s habitat floors, EBSA’s facade automation package includes 4,757 D+H CDC actuators integrated with distributed controls, field wiring and the wider building operation. The project demonstrates repeatable actuation delivered at tower scale as part of one coordinated facade system.

Specialist multi-drive actuation developed around the window geometry.

EBSA’s window-automation scope uses D+H CDM drives in a specialised arrangement with three drives mounted vertically to each applicable window, demonstrating how actuator quantity, position and drive type can be developed around a demanding facade opening rather than a standard hardware layout.

FROM SELECTION TO COMMISSIONING

Carry the actuator decision through the complete project.

The correct actuator selection still has to be translated into coordinated brackets, drawings, power and cabling requirements, control architecture, installation and commissioning. EBSA maintains that connection from design input through field delivery so the installed opening performs as the engineered system intended.

WINDOW ACTUATOR SELECTION

Start with the opening, geometry and required operation.

Whether the project involves a single specialist opening or thousands of automated windows, EBSA can help define the actuator type, drive arrangement, mounting and control pathway around what the facade needs to achieve.
