If my buiding type is not in Energy Star and I don't see it really in the 2003 CBECS PerformanceTargetsTable and I try to use what I think is closest.

I'd like to use 5.4.3.4 Exception g to exclude the need for vestibules for each shop entrance of the shops that our office building has on the street level.

We are working on an ASHRAE 90.1 model in Nevada and are adding the solar information manually to the LEED online forms, post energy modeling (so our solar energy is not appearing on the software g

our project has a district heating with a flat rate of 0.012$/kw and we calculated the virtual rate to be 0.08$/kw can we use the virtual rate or do we have to use the rate provided by the service

Hi, I am currently working in the certification of an industrial building. The industrial processes are consuming a high percentage of the building's energy consumption.

This might have been asked before but will the new 18% prerequisite affect the projects following ASHRAE 90.1 2010 adjusted point scale for LEED 2009? Thanks.

Does anyone have any experience applying the core performance guide under option 3? I'm wondering which version of the guide we're supposed to use.

A building that is being certificate under LEED 2009 will be built in a campus with a dedicated District Energy System (DES) based on a combined heat and power plant (CHP).

This might be a silly quesiton, but when should you submit the optional ASHRAE compliance forms? If it's optional then why should anyone ever submit these forms?

Hi, I am modeling campus building under major renovation. But since that building was built in 1968, no envelope data available (no spec.
