Choosing Baseline HVAC-System in climate zone 1b
NC-2009 EAc1:Optimize Energy Performanceposted by Johannes Hopf on
Hi, 90.1-2007 confuses me a little. Our project (4 story, 9000 m²/90000 ft²) is located in climate zone 1b. The proposed building is heated by an electrical heatpump.

Hi, I have a question about the interpretation of section G3.1.3.13 (VAV minimum flow setpoints).
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
Natural Ventilation - modeling air conditioned as baseline?

“We are working on an existing classroom and office building at the University of Hawaii, which will undergo a complete remodeling under LEED-NC v.3.0.
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.
Efficiency curve
NC-2009 EAc1:Optimize Energy Performanceposted by Francesco Passerini on
The efficiency of the boiler that I’m modeling has to respect Table 6.8.1F of ASHRAE 90.1:2007.
