Lighting is critical in achieving global sustainable goals, including building energy efficiency standards. The United Nations' Sustainable Development Goals (SDGs) include a goal to ensure access to affordable, reliable, sustainable, and modern electrical energy for all (SDG 7) and to make cities and human settlements inclusive, safe, resilient, and sustainable (SDG 11).
Efficient lighting technologies are an important aspect of both of these goals, as they have a significant impact on energy consumption and the livability of cities and human settlements.
One of the key ways that lighting is included in building energy efficient global strategy is through the use of energy-efficient commercial lighting systems. This includes the use of LED lighting, which is significantly more energy-efficient than traditional incandescent or fluorescent lighting. LED lighting can reduce energy consumption by up to 80%, resulting in significant energy savings and reduced greenhouse gas emissions.
Wireless lighting control
Another way lighting is included in building energy efficient global strategy is through wireless, complex lighting control systems. Energy efficiency is becoming increasingly important in commercial applications of wireless lighting control. This includes indoor smart control lighting, street light control, outdoor lighting control, etc. With climate change and increasing energy costs, it is more important than ever to find ways to save energy and reduce greenhouse gas emissions. Wireless lighting control systems, such as those based on Bluetooth mesh technology, offer a powerful solution for achieving building’s energy efficient lighting.
One of the main benefits of advanced lighting control systems is the ability to remotely control and adjust lighting levels through energy efficiency strategies. This can help to reduce energy consumption and costs, as lights can be turned off or dimmed when not needed. For example, with a Bluetooth mesh network, lights can be controlled via a smartphone app or a central hub, making it easy to turn off lights when a room is unoccupied or dim lights in areas not in use.
Additionally, distributed lighting control systems can be integrated with other building management systems, such as HVAC, security, and energy management systems, which can help to improve energy efficiency even further. For example, with the integration of lighting control, HVAC and energy management systems, the building can be more efficiently controlled, and lighting energy savings can be more significant.
According to a study by the US Department of Energy, lighting accounts for around 11% of the energy used in commercial buildings. By implementing a wireless lighting control solution, commercial buildings can reduce their energy consumption and costs.
Energy-efficient lighting control strategies
There are several ways that wireless lighting control energy systems can help to save energy through lighting:
Occupancy sensing: Wireless lighting control systems can be equipped with occupancy sensors, which detect when a room is occupied and turn lights on or off accordingly. This can help to reduce energy consumption by ensuring that lights are not left on unnecessarily.
Daylight harvesting: Wireless lighting control systems can also be integrated with daylight sensors, which can automatically adjust the lighting levels in a space based on the amount of natural light available. This can help to reduce energy consumption by reducing the need for artificial lighting during daylight hours.
Scheduling: Wireless lighting control systems can be programmed to turn lights on and off at specific times, such as during business hours or after hours. This can help to reduce energy consumption by ensuring that lights are not left on when they are not needed.
Dimming: Wireless lighting control systems can also be used to adjust the brightness of lights, which can help to reduce energy consumption by reducing the amount of energy used by each light.
Scene setting: Wireless lighting control systems can be used to set different scenes, which can adjust the lighting levels in different building areas to suit the specific needs of that area. This can help reduce energy consumption by ensuring that lights are not left on unnecessarily or too bright for the need.
Benefits of energy-efficient lighting
Saving energy from lighting can be very beneficial. According to the Lawrence Berkeley National Laboratory, common lighting control strategies can reduce lighting energy consumption by an average 24 to 28 percent energy savings.
Control energy savings can help to save money and contribute to a more sustainable future. There are several energy efficiency benefits from lighting, including:
Reduced energy consumption: One of the main benefits of energy-efficient lighting is that it uses less energy to produce the same amount of light as traditional incandescent or fluorescent lighting. For example, LED lighting can use up to 80% less energy than traditional incandescent lighting.
Lower energy costs: Reduced energy consumption can lead to lower energy costs. With energy-efficient lighting systems, commercial buildings can save a significant amount of money on their energy bills over time.
Longer lifespan: Energy-efficient lighting systems, such as LED lighting, have a longer lifespan than traditional incandescent or fluorescent lighting. This means that they need to be replaced less frequently, resulting in lower maintenance costs and less waste.
Improved lighting quality: Energy-efficient lighting systems, such as LED lighting, can provide better lighting quality than traditional incandescent or fluorescent lighting. This can improve visibility and reduce eye strain, making it a more comfortable and productive environment for building occupants.
Reduced greenhouse gas emissions: Energy-efficient lighting systems can help to reduce greenhouse gas emissions by reducing the amount of energy used. This can help to mitigate the effects of climate change and contribute to a more sustainable future.
Smart lighting control systems can also provide energy efficiency benefits. They can adjust the light level according to the occupancy, daylight and other factors, which can help to reduce energy consumption and costs. They can also be integrated with other building systems, such as HVAC, security and energy management systems, which can help to improve energy efficiency even further.
Traditional lighting control vs. modern lighting control
Traditional lighting control systems involve manual operation, where switches or dimmers are used to turn lights on or off, or adjust their brightness. These systems are often inefficient and can lead to wasted energy, as lights are left on in empty rooms or are unnecessarily bright. In contrast, digital lighting controls use advanced technology such as sensors, timers, and automation to regulate lighting based on occupancy, daylight levels, and other factors that provide potential energy savings. This results in improved energy efficiency, lower costs, and increased comfort for users. Additionally, modern networked lighting controls can be remotely monitored and controlled, allowing for greater flexibility and customization of lighting settings, fulfilling energy building requirements. The lighting controls trends are constantly changing but it's crucial to choose the energy efficient lamps and the right intelligent lighting control system that fulfill our needs.
Initiatives that support building energy management
In addition to the energy-saving benefits of lighting control solutions, there are also various building codes and efficiency rebates that can incentivize the implementation of energy-efficient lighting in commercial spaces and improve building energy performance.
One example is Title 24 in California, which is a set of building energy efficiency standards that aim to increase energy savings and reduce energy consumption in buildings. These standards apply to the design, construction, and operation of buildings, and include specific requirements for lighting systems. By complying with Title 24 standards, building owners can potentially qualify for financial incentives and rebates.
In addition to building energy codes and energy standards, there are also various rebates and incentives available to building owners who implement energy-efficient lighting control platforms, contemporary lighting control solutions. These can include utility rebates, tax credits, and other financial incentives that can help to offset the cost of upgrading to energy efficient technology in lighting.
Overall, by lighting upgrade and implementing energy saving lamps you can help commercial spaces provide energy savings, reduce costs, and meet building codes and standards. By taking advantage of available rebates and incentives, building owners can further increase the financial benefits of upgrading to energy-efficient lighting.
In summary, lighting is an important aspect of building energy efficient global strategy, as it has a significant impact on energy consumption and the livability of cities and human settlements. The use of energy-efficient lighting systems, such as LED lighting, wireless lighting control systems, and smart lighting control systems, can help to reduce energy consumption and costs, and contribute to the United Nations' Sustainable Development Goals.
