Good day, I have the following question regarding the energy modeling of a very large soccer stadium in a hot climate: My proposed design involves floor mounted and side mounted jet fans that are

My project has a dayligh dimming system and alos the curtain of each window. The reviewer ask me to add the effect of how this curtain will be modeled.

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 6.8.1F an

Dear LEED, We are designing a medical office with VRF system, to fulfill iaq requirements we add independent outdoor air unit comprises of supply and exhaust fans on each zone.

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.

I remember reading it somewhere that exhaust fan that is not interlocked the the HVAC should be process energy (room exhaust).

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 temperature (ECW

I am project admin for a V3-2009 NC project and wondered if anyone had issues with energy modeling software and accuracy of results with complicated/unique systems?
