I'm looking to model passive chilled beams and passive displacement ventilation in ApacheHVAC to compare the energy savings to a conventional system.

Is it possible to simulate concrete blocks in a curing chamber using microflo?

I'm trying to model a prison which has mechanical ventilation fans and no air-conditioning. Can this be modelled in microflo?

The sum of the design power of all my fans is about 90Kw but when I run an apache simulation the energy consumption for air distribution fans equals around 500Kw. Why is it so much more?

I have a reference model and a proposed model which differ in terms of materials, lighting efficiency and hvac efficiency. So far I have just create 2 separate IES project files one for the reference and one for the proposed, and ran the simulations in apache separately for each. Is there a way of ...

All my rooms are are using the light gain defined by the lighting templates I defined earlier in building template manager. For example, all offices are using 12w/m2 based on the 'classroom lighting' template I defined. But since having conducted a lighting schedule I know the light gains per ...

What is the purpose of having an unoccupied room representing a stratified zone for displacement ventilation? How does this effect the final simulation/calculations?

I am trying to model an underfloor air distribution system which has underfloor ducts, the flow rate to the underfloor air distributors is controlled by volume control dampers in every duct to determine the flow rate to each distributor in l/s. The air is returned at the ceiling, so it does not get ...

Should I use a fan to represent each individual air distributor or is there a specific component for this?

I have several zones in my building served by different air handling units. So I create a few different multiplex zones to represent those areas, but the design airflow (in l/s) for the rooms within a single zone varies. I just have modelled one fan (in the AHU) going into the multiplex, so I have ...
