Hello, I am working on a project outside US and I am wondering how to approach the mandatory provision below. 6.4.1.5.1 Mechanical Equipment.

Common sense tells me they are not interested in by the second peak energy demands for each end user...so to ask the stupid question: Which average value should I output here...hourly average annua

Hello, We have a project where our resort rooms will be using spray foam insulation above a concrete slab, set in zone 1. Our rooms are actually small villas.

I use Carrier-HAP and according to ASHRAE 90.1 G.1 #4, all baseline HVAC fans should be running continuously when the space is occupied and cycled when the space is unoccupied.

Hi, We are currently responding to LEED Reviewer comments for a building.

Our project involves the new construction of a healthcare clinic that is being heated and cooled via heating and chilled water produced by a campus central plant.

Hello! An educational building will have no AA for its classroom, workshops and labs (mainly 90% of the project area), as all these areas will be naturally ventilated (complying with section 5.1 o

Is it true that the HVAC baseline efficiency in Table 5.8.x is the total HVAC efficiency including fan? I.E.

Hi, I am not sure whether to class mechanical rooms which are free cooled by outside air as "conditioned" for the purpose of the baseline (so the baseline would be on system 5 in this example).
