How should we model the air curtain at the building entrance? Should we model as process load for both baseline and proposed?

We are working in a project that has a gas-fired boiler that supplies hot water for space heating (radiant floor) and domestic hot water.

Do we need to comply with efficiencies in tables 6...

2015- 6:02 am Hi Ivan, this is becoming software specific and detailed. I suggest you repost this on the energyplus yahoo group support forum. You will get your best help there. If I see it there,...

All, new to energy modeling and reviewing the EAp2 online template trying to figure out the required inputs and reports for the Target Finder section, Design vs Target. For which are the Baseline...

Since eQUEST is unable to model dedicated outdoor air system linked to the radial panels, we modeled DOAS units by creating “dummy zones” within the model. Does this simulation method require an...

I remember reading it somewhere that exhaust fan that is not interlocked the the HVAC should be...

I wonder if there is a standard to convert C-factor to U-factor or F-factor to U-factor. Is there a guideline to do so? Since not all energy program can let you input C, U, F as you desire....

Dear All,
I’m modelling a water centrifugal chiller in System 8 of ASHRAE 90.1 (Appendix G), using HAP by Carrier.
I have to need how calculate the minimum entering condenser water...

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5903 thumbs up March 16, 2015- 1:00 pm There are quite often work arounds for most newer systems that may not be directly addressed by the software. In general a good modeler will make sure that the system in the project can be modeled (either directly or with an established work around) by the software being used. Commercial software like Trace should have technical support that could recommend how to model a unique system. Other software may have similar help available, if not perhaps posting on one of the discussion forums...

I haven't energy modeled yet and am reviewing someone else's work on EAp2. This is for LEED v3.

In Table EAp2-1, how does "Regularly Occupied GSF" and "Unconditioned GSF" affect this...
