I’m modeling a hotel (5 storey, one floor is underground) in which there are also offices, a coffee bar, a wellness center...

Hi, we have been using the "Advanced Energy Modelling For LEED" document and have a question one some of the exceptional calculation methodology examples.

I have a project where there will be an addition to an existing building that is also being renovated.

Hello All, We are now preparing the Energy modelling for one of our projects located outside USA. It is a 2 storey non-residential building with VRV system for cooling only.

For HVAC System in Baseline case of modelling, it says: "Operate fan contiuously when spaces are occupied and cycle it during unoccupied hours".

Hello guys. I am modelling a hotel for LEED purpose.

In the building which I’m modelling there are plastic skylights which are practically opaque.
