ASHRAE compliance with naturally ventilated building
NC-2009 EAc1:Optimize Energy Performanceposted by Jean Marais on
As per the guidelines, my baseline mechanical system is incorporated into the naturally ventilated design case model 1 to 1, as a priority 2 kind of system that kicks in when the naturally ventilat
Conditioned vs. unconditioned & natural ventilation
NC-2009 EAc1:Optimize Energy Performanceposted by SmithGroup BG+LU FW on
Table G3.1 in Appendix G requires only conditioned space be simulated as being both heated and cooled in the proposed design.
EAc1 Space Cooling and Heating
NC-2009 EAc1:Optimize Energy Performanceposted by Mark Rawson on
Hello, When I generate the EAc1 Summary Report in HAP I have a negative percent savings in space cooling and heating in the performance rating table.
shgc Values
NC-2009 EAc1:Optimize Energy Performanceposted by TOMAS URIBE on
Hello Marcus. The fenestration supplier of a project gave us SHGC values from a simulation. We would like to know if it is acceptable for LEED simulation.

The efficiency of the boiler that I’m modeling has to respect Table 6.8.1F of ASHRAE 90.1:2007.
Appendix G - Baseline Building Rotations
NC-2009 EAc1:Optimize Energy Performanceposted by Kalyan Nishtala on
Hi All, Are baseline building rotations necessary for a new building that is connected to an existing building. Note that the new building is being modeled as a stand alone.
Process Load
NC-2009 EAc1:Optimize Energy Performanceposted by Muzammal Abbas on
Dear all, We are doing a factory project in pakistan, which have a 1200 kw process machinery load, after energy modeling without process load we are saving 55 % from baseline but after adding proce
