Dear all, I'm establishing a baseline model for an office building in ASHRAE climate zone 6. The HVAC system of the proposed building only has heating radiators using municipal supplies for winter

Dear community, we are doing a 90.1 App. G simulation for an existing manufacturing warehouse renovation + office building addition.

I have to model a heat pump that outside the building exchanges heat with the external air and it exchanges heat with the building, i.e. with the internal part of the HVAC plant, thorough water.

Dear community, I would like clarifications about the scope covered by the section 10-4 of the ashrae 90.1-2007: in an industrial project, there may be lots of electric motors related to the indu

Hi: We are working in a project in Lima Perú and the HVAC Engineer has just sent to us a submittal sheet of a Magnetic Chiller with a COP of 10,8.

Ok I am new to LEED but my architect is telling me that most of the LEED submission take place after the construction documents are done.

There are several unconditioned spaces in a project that I'm working on. For Energy simulation, should those spaces be modeled as having cooling & heating systems?

It is true that the R values in 90.1 have to be used as a minimum in the performance rating calculations? Using tables and materials description sets the basis for your baseline model?

Dear all We're working in the energetic simulation for the credit EA p 2 in LEED NC 2009 in a Data Center building.

Hi, I have to recalculate the chiller COP of Baseline Building, to consider the power of the fans? Or just put the COP marked by Standard 90.1 and attributed the fan power calculated by the Stan
