Dear LEEDusers,

A question related with the proposed and baseline building energy models for a BD+C project:

For an existing building where only single parts of the envelope will be modified, only the roof and a skylight, shall the assemblies and % of fenestration between proposed and baseline models be equal, right?
Modified elements only will represent differences between proposed and baseline related to the renovation actions but baseline ones will not be afected by Ashrae assemblies (tables 5.5-1 through 5.5-8) nor % of vertical fenestration. Neither for modified existing elements or existing not modified elements. Is that right?

In case the project will not suffer any envelope modification and the project turns to Comercial Interiors: 
Envelopes between proposed and baseline will vary attending to the reduction of  % fenestration and the apllication of U-factor values for the different assemblies represented in Ashrae tables 5.5-1 through 5.5-8 of (applied to the baseline model). Is this correct?

Regards,
