Do I have to chose one categorization procedure (Building Area or Space by Space Method) to determine the lighting power density (LPD) in the Baseline Energy Model? My building is Mixed-Use so I h

I wonder whether daylight sensing (lights are dimmed automatically according to daylight) can increase the points a project can obtain in this credit. Table G36.2 doesn’t mention such a system.

Hi Is lift energy included as a process load as part of the 25% minimum requirement for process loads? If so are there any references or guidance on how to estimate its energy consumption.

We are working on a college campus that will have a new central plant. We have a onsite micro turbine generators that provide power to the site.

I just wanted to verify that "Two (2) points mandatory for all LEED for New Construction projects registered after June 26, 2007" rule is no longer in effect. Referring to this: http://www.usgbc.o

A note of Table G3.1.1A of ASHRAE 90.1-2007 states that "For all-electric buildings, the heating shall be electric resistance".

Hi, We've only done the mechanical portion for this project but the client assigned to us the EAc1 credits.

I have a design using a full building energy model in order to achieve as many credits as possible under EAc1.

HI! I would like to take a question about data center's based on Ashrae 90.1 2007 for Leed 2009. In Appendix G "Performance Rating Method", in Baseline Building Performance, I have to attribute a
