As a contracting authority, you don’t want to buy the cheapest solution. You want the solution which holds the most benefit for you in the long run. The Office Indoor Lighting LCC-Tool (Life Cycle Costing tool) will help you to find that solution! This tool will help you calculate and estimate the purchase price for your indoor lighting project, the total cost of ownership and the (external) environmental costs that the project comprises. The tool can be used for acquiring as well as leasing indoor lighting.
