In modern buildings where the thermal envelope has a high level of insulation and therefore thermal performance overheating has become a much more significant issue. The management of internal heat gain is therefore a key issue and solar gain is one of the key sources.
atBOS Shading Control allows the control of external shades, blinds or curtains to minimise unwanted solar gain whilst maintaining appropriate levels of ambient light. The system also has the potential to ensure beneficial solar heat gain is maximised in winter to reduce heating loads.
atBOS Shading Control is appropriate for any scale of building, and includes controlhardware and software.
Suitable for domestic and commercial buildings
Can be installed in new or retrofit projects
Can integrate with any type of shading device.
- Wireless communication means that installation only requires power connection and can be carried out by a system does not require separate communication cabling
- Simple user interface via physical interface such as switch orAtamate HAZETM
- Easy to set up and run based on a calendar or automatically from sensors.
- Single technology platform means full integration with control of atBOS HVAC and Natural Vent Control to optimise performance and occupant experience
- Manual control can be achieved through shared controls, such as theAtamate HAZETM or the web based user interface
- Given that infrastructure is shared with other elements of atBOS and only power connections are required, first costs are low
- Optimising the operation of shading systems will result in reduced energy consumption and therefore lower bills
Key Aspects of Shading Control
atBOS uses a range of pre-programmed strategies to control shading systems in a building. These range from simple zone based occupancy and temperature sensing, through to advanced Machine Learning (ML) which has potential to account for predicted weather patterns such as cloud cover.
Occupancy based control, shades are closed when spaces are unoccupied if it is beneficial to prevent overheating.
Control shading as part of a passive cooling strategy
Daylight control where shades are part closed if ambient light levels exceed a user defined threshold
Improve convenience and safety through automating hard to reach blinds
Prevent glare on screens and monitors
Use Responses to understand if a blind motor may have failed and report requirement for maintenance.
Control protocols
atBOS software will control most blind and curtain motors using the following methods:
Volt free contact, open/close relays for proprietary systems
Direct relay control or 0-10V analogue signals for actuators
Connection to third party proprietary control systems through industry standard open protocols such as Modbus and BACnet.
Direct native mesh wireless communication.
HVAC CONTROL
Reduce energy and provide an ideal indoor environment
