Re: Add Fuels to BRPM Report?

Typically I lump all of this usage in receptacle. I then provide a narrative and some screenshots or similar to USGBC documenting your inputs.

In other words, there's no requirement you break them out in your reporting. You just have to show they've been included.

If you want greater details The ...

Modeling HVAC Systems for Final LEED Submission

I have a project which is completing design and I need to finalize my IES model for submission to USGBC.

How do I build the Proposed HVAC systems so they have enough detail for LEED?

For example, the project HVAC engineer has provided a mechanical schedule with a couple dozen Fan Coil units. There ...

Re: ASHRAE PRM - HVAC Loads Low

Thanks for your response.

What do you usually do when this mismatch is costing performance. I've not typically been successful telling the ME to downsize his system.

In regards to the schedule. In my experience engineering practice does NOT apply schedules to the internal loads during sizing. They ...

ASHRAE PRM - HVAC Loads Low

I’m working on an early phase LEED/ASHRAE PRM model.

The building loads (both baseline and proposed) calculated are too low to be believed. I work at a Mechanical Engineering firm and have 10 years energy modelling experience and 5 year HVAC design experience. The loads as simply lower than any ...

ASHRAE PRM - Low HVAC Loads

I’m working on an early phase LEED/ASHRAE PRM model. I work in a mechanical engineering firm, and have 10 yrs experience as an energy modeler, and 5+ years experience as an HVAC designer.

The building loads (both baseline and proposed) calculated by the PRM simulation are too low to be believed ...
