The website https://www.trilux.com/en/service/trilux-portal/efficiency-calculator/ provides an online tool for comparing the profitability of lighting installations. It facilitates comparing up to 5 lighting installations in terms of their energy consumption and CO2 emissions as well as costs for installation, lamps, energy and total costs per year.
TRILUX Online Efficiency Calculator
The extent of parameters to be considered can be selected from three levels – "quick", "standard" and "advanced". Quick estimates can be calculated just as well as detailed considerations factoring in multi-component lighting systems, savings through light management, installation costs, repair costs, lamp and maintenance costs, CO2 emissions and price increase rates as well as day and night rates for electrical power.
Data entry is done online in the input template "Calculation" (see figure).
A further template, "Project configuration", facilitates entering personal data of the processor, a project description as well as project-specific calculation pre-settings.
The following additional functions enhance the efficiency calculator’s benefits and support rational work with the tool:
automated summary of the results in a PDF file which can be stored and, where required, sent e.g. conveniently via e-mail (see figure).
extensive range of online examples
local storage of personal calculations to be reloaded as a starting point for later calculations at any time
extensive lamp list with data on lamp and system performance
The evaluation facilitates an assessment of profitability based on the comparison of accumulating costs and savings potential. Particularly the profit opportunities resulting from various investments (TPO, see figure) in relation to the utilisation period to be considered are determined and contrasted.
The efficiency calculator is available in 14 languages with 12 currency designations.
