Lighting calculation in smart cities is a complex process that requires the help of intelligent technologies in order to guarantee a series of functions connected to lighting systems, from a smart perspective. How is lighting calculation carried out in smart cities? To obtain an optimal calculation, complex algorithms are adopted in order to analyse the collected data and develop efficient and effective lighting solutions that meet the functional and structural needs of each area of the smart city.
The lighting calculation in smart city, provides for the determination of the basic quantitative and qualitative requirement, to achieve a certain lighting value, for a specific area or urban space, taking into account precise factors, first of all, the surrounding environment.
In the design of the smart city, technology plays a fundamental role in the management of public lighting, and lighting calculation becomes an essential element for ensuring optimal results. For this reason, we are looking for innovative lighting solutions with a high technological content, which can work through a valid integrated network, one that allows the management and control of urban public lighting.
To determine how to carry out the lighting calculation in smart cities it is necessary, for each area or space:
- to define lighting requirements, taking into account the intended use (e.g. roads, parks, public buildings);
- to determine the lighting requirements, such as, for example, the amount of light required, the spatial distribution, the uniformity of lighting;
- to select the most suitable lighting systems, taking into account the availability of natural light, lighting needs, energy efficiency;
- to calculate the number of luminaires required for each installation point, in order to obtain the required lighting level;
- to calculate the amount of light required, through the assessment of luminance and of average illumination;
- to assess the availability of natural light: this includes assessing the amount of natural light, available in every area of the city, during the day and night;
- to check the quality of the light, evaluating factors such as colour temperature, colour rendering index (CRI) and glare;
- to evaluate the energy efficiency of the lighting system, considering factors such as energy consumption, the useful life of the devices and maintenance costs.
A well executed lighting calculation offers advantages in terms of energy savings. By using efficient lighting technology, smart cities can reduce energy costs and contribute to environmental sustainability.
It offers advantages in terms of improving the quality of life, since adequate lighting improves the urban environment and the experience of citizens in their public and private spaces.
Lighting calculation can be performed by specialised software, which can automate the calculation process and make the design more efficient.
It is important to note that lighting calculation is a complex process: the accuracy of the calculation depends on multiple factors, including, as already highlighted, the quality of the input data and knowledge of lighting standards and techniques.
In conclusion, lighting calculation in smart cities requires a combination of professional and technical knowledge, experience and expertise in the use of smart technology, to ensure that smart public lighting is adequately and sustainably designed.
