Simulating Existing Lighting Installation

Postby Daithi » Tue Feb 22, 2011 12:35 pm

Hi all,

I am trying to simulate an existing office building in IES. I am wondering what methods are available to simulate the energy consumption and casual heat gains from artificial lighting?

It appears one way is to count the number and type of lights in each space (onsite) and enter these under the Internal Gains tab of each room.

Rather than counting the fittings on site, is there a way of entering the light type (eg T8 Low Frequency Ballast Lighting, Compact Fluorescent Lighting (CFL), or Tungsten Spot Lighting) and a design illuminance for each space?

Finally, if I wanted to go further and check for lighting comfort (ie acceptable levels of glare, contrast, etc) would this involve inputting the position of each artificial light and simulating in Radiance?

Regards,

Daithi.
