Choose light for your home: economical and environmentally friendly. Rising energy costs and climate change on a global basis make it increasingly important to save energy and minimize our carbon footprint. If you choose more energy-efficient light bulbs you can reduce your power consumption, energy costs and CO2 emissions considerably. Use OSRAM Light-a-Home and find out how much you can save in your home. Simply compare the light bulbs you are currently using with our OSRAM energy savers.
Calculating tool for economical and energy-efficient lighting systems. Besides the ideal illumination and the numerous application possibilities, the economical aspect of a light system gets more and more important for the purchase decision. With the right lighting system, you save energy, costs and reduce CO2 emissions.
How much you can save with an innovative light system from OSRAM will be demonstrated with our Light-Consultant. This tool enables you to compare conventional light systems with energy-saving solutions from OSRAM for different light projects. You see at a glance how fast a system change pays back and which savings can be achieved.
VELUX Daylight Visualizer is a simple tool for daylighting design and analysis. It is intended to promote the use of daylight in buildings and to aid professionals by predicting and documenting daylight levels and appearance of a space prior to realization of the building design.
The Daylight Visualizer intuitive modeling tool permit quick generation of 3D models in which roof and facade windows are freely inserted. The program also permits users to import 3D models generated by CAD programs in order to facilitate a good workflow and provide flexibility to the model geometry.
Other features include predefined settings, a surface editor, site specifications, flexible view settings as well as multiple daylight parametrics providing accurate predictions. Simulation output: luminance, illuminance, daylight factor and daylight/sunlight animation.

Determination of daylight autonomy and lighting energy needs in rooms with different types of façade
As a general rule, complex measurements and calculations are required to determine the precise impact of different façades on indoor lighting conditions, artificial lighting requirements and the indoor heat gains that stem from lighting. These calculations are often too costly and time-consuming to perform in the initial stage of planning a building, yet many of the most important decisions concerning daylight availability are nevertheless made at precisely this stage of the process. This calculation tool has been designed to support the decision-making process. The program allows you to quickly compare different variants with tolerable deviations in order to identify the optimum solution at an early stage. It also provides you with a quick overview of the effects of different measures involving the structure (façade geometry, obstructions, etc.) and the engineering of the façade itself. The tool allows you to assess the quantities of daylight available for rough openings and calculate working figures for the relative operating times and daylight autonomy for 10 different façade systems. The annual energy saving potential can be determined on this basis, and it is even possible to calculate figures for lighting energy needs by specifying the installed output of the artificial lighting system and entering data on the type of lighting control system.
The Sensor Placement + Optimization Tool SPOT™
SPOT assists a designer in quantifying the existing or intended electric lighting and annual daylighting characteristics of a given space, produce a variety of daylighting performance metrics and reports, and to help establish the optimal photosensor placement for the space relative to annual performance and annual energy savings.
The software can be used for all types of spaces, though is limited to simple orthogonal geometry. SPOT™ handles top and side daylight sources and can model any electric lighting source. The software uses a Microsoft® Excel platform with a RADIANCE engine.
The LED Road Calculator app is an easy support tool that enables you to find the right luminaire version by selecting the required lighting parameters that are relevant for your Outdoor lighting project in a few steps.
The result gives a recommendation of the most suitable luminaire version with ordering code. Based on single-sided lighting installation parameters and the choice of the luminaire, it will give the best solution in term of luminaire version, maximum pole spacing and system power.
