Hi, I know that Appendix G states that if the envelope of a building is renovated, then the existing envelope construction is used for the baseline.

Hi, on a recent project we were requested to provide evidence that 5 buildings built within the last three years did not have carbon monoxide sensors installed in the basement car parks in order to

FYI only, I believe this is useful information for LEEDuser community as well.

We are modelling a building with water cooled chillers. We are preparing a baseline plant for LEED NC 2009. For the check of necessary plant efficiencies we checked the minimal efficiencies with co

We are working on a higher ed. project building connected to a campus-wide district heating/cooling and power plant.

I am in the process of submitting the LEED templates (2009 NC) for EAp2/EAc1. The building in question has been modeled using Energy Pro and has calculated a baseline virtual energy rate for natur

In a previous post titled "DES Energy Cost" dating back to May 13, 2013, my interpretation of the responses in the thread is that a project can choose to either follow 90.1 or the DES Guidance from

Is there a guidance document/discussion available on how to treat a campus geothermal loop (servicing several buildings) that provides the working fluid to the LEED project building conditioned wit

I am currently working on a LEED v3.0 model in trace 700. It is a historic building originally built in the late 1800s. It has a variety of unique situations that I am unsure of how to model.

Hello, In the proposed design, the HVAC system operates using plenum zones as return air path. Should I use the plenums as return air path in the baseline model as well? Thank you
