Hi All, I am modelling a VRF system using ApacheHVAC in IES. But have no idea which prototype to choose.

I am working on an existing building renovation where there is a significant amount of building floor area that is crawlspace and attic area.

I looked thru all 2000+ comments and didn't see this addressed. I have a hotel project with a pool, fitness room, vending/ice machines, ect.

I’m working on project with two mid-rise buildings, one for the office and the other is for parking garage mostly are naturally ventilated.

Hello: I have a 3 story mixed use healthcare facility with offices, exam rooms, treatment rooms, research areas, and a surgical suite.

Hi, Our office building is ventilated with a constant volume AHU and conditioned by VRF system. AHU supplies 100% fresh air to the spaces, while VRF system provides heating and cooling.

I have wall assemblies with no cavity insulation but 3-4 inches rigid insulation outboard of structural sheathing. The wall is finished by a composite metal panel.

Hello, I´ve a question about thermal zonification in my energetic model. I use Energy+ and my proposed HVAC system is Geothermal Heat Pump, AHUs for ventilation requeriments, Fan-Coils and Radian

Dear all, I need to know if anyone did experience that before.

The owner would like to eliminate economizers on a few of the air handlers.
