We have a residential project - with a double height entrance lobby (main entrance to the bldg) - and I am not sure how to calculate the LPD for this space - should I treat it as: 1) Lobby (14W/m2

Hi, I’m currently working on a LEED 2009-CI project applied to a hypermarket and I’m having doubts in classifying some surfaces according to table 9.4.5 of ASHRAE 90.1 2007 (“Lighting Power Densi

When you claim a lighting allowance for Decorative appearance you get 1 watt/sf.

Let me preface my question with some context. I have a client (world famous for their electronic gadgets) who is building a lab for research and development of new gadgets and components.

I have a project in which my calculated area by space by space method is slightly more than the area inserted by LEED Admin in "Gross Project Square Footage". Should these numbers match?

We are working on a LEED-CI project in a large commercial office building, where the overall 'building area' method would clearly be office at 1 W/sf.

Can de-lamping be acceptable to meet the Lighting Power Density Requirements?

To achieve energy efficiency a project in Bangladesh is planning on buying T8 LED lights with following specifications.

We are installing a living green wall in the lobby of our 2009 CI project. We need to install grow lights for proper plant health.
