The application is used to calculate the consumption of lighting systems using the LENI (Lighting Energy Numeric Indicator) in accordance with European standard EN 15193. In just a few simple steps the energy efficiency of the system can be estimated, taking both the fixtures and the lighting control systems into con- sideration. This indicator makes it possible to estimate the TCO, or the Total Cost of Ownership, of the system.

Design choices can be suggested to customers by comparing various lighting solutions and the related procedures to control the fixtures. The application can be used to calculate all the information on the initial energy and maintenance costs of the systems and allows a fast and accurate evaluation as to whether one design solution is better than other options. It is therefore possible to evaluate any product that is available on the market, such as the new LED fixtures and the Building Automation control solutions.

The web-based architecture allows the application to be accessed from any browser that can connect via intranet/internet to the server hosting the software and the projects/products database.
The workspace is organised into project folders which contain the areas:

• Project folder: set of documents dedicated to the same business, for example a building.

• Area: always represents a single room inside a building. One or more Solutions, that is, design variations made up of different fixtures, possibly managed with different control systems and/or procedures, can be specified for each area. Thus the type of fixtures used (of which there may of course be more than one) can be specified for each solution. The mode of management must be specified for each type of fixture, selecting from options that may be manual (traditional) or automatic control (via control systems). Data relating to the energy and economic parameters of fixtures and systems can be entered in various ways:

• all the parameters are entered by the user, for example for third-party fixtures.

• the products in the company database are entered by the user; in this case the user only has to select the type of product and all the parameters will be filled in automatically. Even in the second case, the user can still edit and therefore personalise the parameters, since these have just been copied into the area from the database. Thus, if the data of a fixture are modified in the database, for example a price in a price list or an energy parameter, this will not modify any of the areas in which this fixture may have been used. After entering the data, the application will automatically carry out the energy and economic evaluations, the results of which will be displayed in the relevant sections and can be exported into a PDF document. The information produced by the application regard the following:

• Energy consumption

• Amount of CO2 produced

• LENI

• Energy comparison of solutions

• Initial investment costs

• Energy consumption costs

• System maintenance costs

• TCO

• Investment payback time.

The maintenance costs include bulb replacement, the labour needed for replacement activities and any extra costs that may be required, such as the hiring of machinery to change bulbs at great heights or the costs of cleaning fixtures in critical applications. Besides evaluating a single room (area) it is also possible to perform an overall evaluation of the building (project folder). One or more Proposals can therefore be carried out, in which a solution is selected for each area contained in the project folder. After the Proposal data have all been entered, the application will automatically carry out the overall energy and economic evaluations, the results of which will be displayed in the relevant sections and can be exported into a summary PDF document. It is important to remember that all the data relating to projects and products are saved on the server whereas the PDF documents that are generated must be filed by the user in his/her PC.
