Automatic calculation of LENI
Proven method to calculate the energy demands for lighting isLENI LENI stands for Lighting Energy Numeric Indicator
Most of the parameters needed for LENI calculation are already
given in a 3D lighting design
Some parameters have to be determined by the user, of course withthe help of software:
Daylight time usage / non daylight time usage
Availability of presence detection Availability of daylight control
The calculation is done by software, the user just defines theparameters

Daylit Zones
On the right hand side the software displays the calculated daylit area
Due to visual feedback, the designer selects a daylight control system forthis area and the lighting system therein
In real time the new LENI value is calculated and it decreases from21.84 kWh/(m x a) to 18.06kWh/(m x a) = - 4%in this simple example

Energetic optimization
Shop lighting example:
Attract people, draw the attention to products, invite to stay, highlight the
productsgood color rendering, emphasize important products
