DIALuxFeatures

DIALux offers an import and export to DXF, DWG or gbXML (BIM)

Direct interface (STF) e.g. to Autodesk MEP, Revit, DDS, Allplan...

Drag & Drop of required drawings, texts, diagrams or further information intoCAD application or any other programs like Word, Power Point, ... .

DIALux works with PlugIns or simple IES files

Estimation of energy demands in the lighting design phase

Energetic optimization, finding the best product

Software aided design and optimization

Consideration of all parameters including daylight and control

systems

Calculating the energy costs

Detection of the best solution

Calculating the ROI

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
