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.

ASHRAE 90.1 -2007 has following clause. 6.4.3.9 Ventilation Controls for High-Occupancy Areas.

I am modeling a shell office building project for LEED 2009 using ASHRAE 90.1-2007 as the basis for modeling.

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?
