![]() The reality, however, is that this decision is project specific. In general, a case can be made that motorized shading is always worth the extra cost. Is a motorized shading system worth the extra cost? Solarai's predictive solar control solves all of these problems ensuring shades are always in the optimal position to maximize building performance while giving architects and designers the flexibility they need make their vision a reality without compromise. #SHADE CONTROL SYSTEMS INSTALL#Second, facade mounted sensor arrays are not only costly to initially install and maintain, but also unsightly, compromising the architectural beauty of a building's design. Unwanted solar energy and uncomfortable glare have already penetrated the envelope resulting in an underperforming building that is uncomfortable for its' occupants. Unfortunately, this response is not instantaneous so the shades remain in the wrong position until the signal from the sensor is received and the shades have had time to move. First, in a reactive system, when sun becomes incident on a sensor the corresponding shade or group of shades will respond. The reality is a large number of sensors often points to a reactive control strategy which is not desirable for the following reasons. Not only does this save money and preserve building aesthetics by eliminating large unsightly facade mounted sensor arrays, but it is simply a better control strategy. With Solarai, a small number of centrally located sensors, often mounted out of sight on the roof, can service an entire building providing configurable overrides to retract shades in overcast conditions, protect the system in windy conditions, and more. Sensors are only used to determine general environmental conditions and not for basic positioning of individual shading elements. They are simply not needed due to the innovative predictive solar control features built into Solarai controllers. When comparing Solarai to competing control systems, people often are shocked by the relatively small number of sensors required. Why are there so few sensors in a Solarai system? Sensors can also be added to enhance the operation under varying environmental conditions such as overcast skies, but with predictive solar control they are not required for optimal positioning. This is done by taking into account many factors including time of day/year, a building's geographical coordinates, orientation of shading elements in 3d space, advanced environmental modeling such as overshadowing and reflected glare, glare protection regions, building performance specifications, and more. in a good way! By using proprietary solar angle of incidence algorithms, Solarai controls predict the solar path and calculate the exact position of the sun relative to each individual shading element to ensure they are always in the optimal position. When the sun hits a sensor, the shade should already have been deployed, however, it takes some time for the system to react and during that time unwanted solar energy and glare enter the building.Įmbedia's Solarai line of controls is different. Take a system relying on brightness sensors for shade deployment as an example. These methods are reactive and inflexible often resulting in shade positioning that is less than ideal or simply too late. What is predictive solar control?Ĭompeting control systems often rely on arrays of sensors or static scheduling tables for basic positioning of shading elements. By enabling each motor or control unit to determine the optimal position for its' associated shading element, single points of failure within the system are effectively eliminated leading to a far more robust and reliable control system. Distributed intelligence is a control strategy pioneered by Embedia that eliminates the reliance on a centralized server or controller for critical system functions. ![]()
