I have a project where there will be an addition to an existing building that is also being renovated. As far as EAc1 is concerned, for achieving 12% better than baseline for new buildings and 8...

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.

We...

EA Credit 1 allows for different percentages of energy performance for "Existing Building Renovations" than for "New Buildings", but there does not appear to be any information in the reference...
