We are looking at a high rise residential project, to be NCV2009. Our electrician is stating all hallways need occupancy sensors.

Hello, our project has 40 electrical table top water heaters. The electrical input is 2 kW and 5 liter storage. What is the right way for modeling the baseline builing water heating equipment?

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?
