1 Choose the right components

One of the most important factors that affect the energy efficiency of your devices is the choice of components. You should select the components that match the specifications and requirements of your device, and avoid over-engineering or under-engineering them. For example, you should use low-power microcontrollers, sensors, and memory modules for low-end devices, and high-performance processors, graphics cards, and storage devices for high-end devices. You should also consider the trade-offs between different types of components, such as wired or wireless connectivity, analog or digital signals, and AC or DC power.

With today's technology majority of applications benefit from adopting wireless lighting controls technology. Wireless lighting systems are made up of physical devices and a communications network that securely collects data and controls the system. The light fixtures are still hard-wired for power, but all communication and data to the in-room devices is done wirelessly. This go-to solution for contractors is relatively new. BENEFITS Flexibility: devices can be placed where they’re needed without limitation imposed by wiring. Labor and material cost savings: eliminates control wiring and conduit. Scalability: easy to expand and add new rooms or zones. CHALLENGES Distance Limitations: devices and their limitations.

2 Optimize the software

Another key factor that influences the energy efficiency of your devices is the software that runs on them. You should optimize the software to reduce the computational and communication overhead, and to leverage the hardware capabilities. For example, you should use efficient algorithms and data structures, minimize the number of instructions and loops, and avoid unnecessary or redundant operations. You should also use power management techniques, such as sleep modes, interrupts, and dynamic voltage and frequency scaling, to adjust the power consumption according to the workload and the battery level.

We often forget but our building lighting controls systems often implement software too. All Casambi software components, firmware inside LED-drivers, mobile applications for Apple and Android devices as well our 24/7 cloud service can be updated easily over-the-air after the installation. iBeacon is a technology by Apple enabling location awareness possibilities for apps such as your lighting controls. Leveraging BLE, a device with iBeacon technology can be used to establish a region around an object. This allows an iOS device to determine when it has entered or left the region. The Casambi cloud acts as a central point for managing configurations and sharing accesses to networks.

3 Design for thermal management

A third crucial factor that affects the energy efficiency of your devices is the thermal management. You should design your devices to dissipate the heat generated by the components, and to prevent overheating or thermal throttling. For example, you should use appropriate materials, shapes, and sizes for the device casing, and provide adequate ventilation and cooling systems. You should also monitor the temperature and the fan speed of your devices, and use thermal sensors and controllers to regulate them.

4 Test and measure

A fourth essential factor that ensures the energy efficiency of your devices is the testing and measurement. You should test your devices under various conditions and scenarios, and measure their power consumption and performance. For example, you should use power analyzers, oscilloscopes, and multimeters to measure the current, voltage, and power of your devices, and use benchmarks, simulators, and profilers to measure their speed, accuracy, and functionality. You should also compare your devices with similar or competing products, and identify the areas of improvement or innovation.

5 Follow the standards and best practices

A fifth important factor that guarantees the energy efficiency of your devices is the compliance with the standards and best practices. You should follow the guidelines and recommendations of the relevant organizations and authorities, and adhere to the industry standards and regulations. For example, you should follow the Energy Star, EPEAT, or RoHS labels for your devices, and use the ISO 50001, IEEE 1621, or ASHRAE 90.1 standards for your engineering processes. You should also learn from the best practices and case studies of other device engineers, and adopt the proven methods and techniques.

By applying these effective ways to ensure energy efficiency in your devices, you can not only save energy and reduce costs, but also enhance the quality and value of your products. You can also contribute to the global efforts to combat climate change and protect the environment. Energy efficiency is not a constraint, but an opportunity for device engineering.
