Did anyone actually validate the HVAC load and energy simulation data of the R2022 features? And do you have enough confidence that it is usable for design and ditched 3rd party software (Trane Trace, HAP, Trace 3D etc.)?
I had spent quite some time with older Revit versions and concluded the results are more like guesses and at most usable for initial estimates and not for actual design (like where I stamp the results and get in trouble if it is wrong). Some lack of features that scare me was no ERV function, and lack of other features to be set that would have an impact on load and energy calculation.
So I ended using Trace 700 (and now Trace 3D). I'm not really happy with Trace 3D, and also want to do more in Revit as long as it is correct. I looked a bit into the System Analysis features of R2022. But it seems limited and clunky for what details one can decide on. This is sad, since not using a 3rd party software would be much more efficient and would have fewer errors transferring information. If I have a choice for accuracy, I really would like the Load part to be correct over the energy simulation. The load calc is what I actually stamp, and what is needed for every project.
Every single year we are waiting for a valid tool inside Revit, that we could really trust, but even today with Revit 2022, we are all still wondering whether we can trust it for loads calculations, or not.
But load has to be reasonably correct since all systems are sized based on that. Too large, and we waste equipment and operate outside good operating ranges (short cycling etc.), too small and we freeze or sweat.
I'm not even sure if the 3rd party software (Trane, Carrier) have some sort of certification for the load. I just know all designers use them. I know some energy efficiency organizations (like for energy efficiency tax credits etc.) have a list of approved software. But I'm not aware of an approved list for load calculation. I know the software manufacturers go great lengths to put all responsibility on the designer.
Has anyone had success running HVAC loads within Revit 23...my whole office uses the affected chipsets Open studio claims are not compatible. We are trying to update workflows, and this is a huge hurdle. Looking for the hive knowledge.
I divided the floor into different thermal zone like below.
!
The HVAC result shows the G zone on the 3rd floor got a very high cooling load, it can be very abnormal cause the zone does not have any external window at all. And the cooling load result of G zone on the 3rd floor is much larger than the result of G zone on the 2nd floor.
This is a large GH definition and you really should upload a small sample needed to recreate your issue. But your geometry is clean and, just looking at your model, I see that your interior floors are not well insulated. I can also see that they also have no thermal mass:

If you are considering replacing your current HVAC system or installing a brand-new HVAC unit for your property, you may be presented with some unfamiliar terminology during this process. HVAC loads are one of the most important factors in determining the right size for your new heating and cooling system.
If you want to understand HVAC load as it pertains to a home addition, make sure you read the article How to Choose an HVAC System for Your Home Addition as well. Here are some of the basics that you should know about HVAC loads and what they mean for your heating and cooling system.
In simple terms, HVAC loads refer to the precise number of BTUs or British Thermal Units, that are required to heat or cool a specific indoor space. This figure can vary considerably depending on a few factors, including the:
HVAC loads are often referred to in tons because that is how most HVAC units are sized. For example, a two-ton HVAC unit would be suitable for some small homes. The tons in HVAC capacity ratings, however, do not refer to the weight measurement of 2,000 pounds. Instead, an HVAC ton is the ability to remove 12,000 BTUs of heat per hour.
Choosing an HVAC system of the appropriate capacity can help you to meet the average HVAC load required by your home or business. This can ensure much greater comfort indoors while keeping your cooling costs as low as possible. Working with a qualified and knowledgeable HVAC contractor is the best way to determine the appropriate size for your new system and to ensure many years of trouble-free service from your heating and cooling equipment.

HVAC sizes are measured in tons - most commercial HVAC systems range between 2 tons and 30 tons. A 1 ton HVAC can remove around 12,000 Btu (British Thermal Units) of heat per hour. You will need to calculate the building's cooling load to know the appropriate capacity of the air conditioner to use.
As discussed earlier, your building's cooling load depends on several factors such as average external temperature to building design, orientation, and its primary purpose. However, a general rule of thumb is that it takes approximately 25 Btu to cool one square foot.
Another thing you must take into consideration are heat load and cooling load calculations. That requires precise estimates for heat gain vs heat loss in your building. The procedures published by the Air Conditioning Contractors of America (ACCA) are useful for this purpose.
Heating load calculations help to estimate the amount of heat loss from the building during the coldest climates. In some cases internal heat sources such as occupants, lighting, and building activity can help to compensate for heat loss.
Cooling load calculations are for estimating the heat gain in a building during the hottest part of the day. Internal factors add to the cooling load, similar to what we outlined in the previous sections.
You can also get an accurate HVAC sizing estimation by calculating the space heat gain (the amount of air entering the building) and the space cooling load (the amount of air that needs to be removed).
The ASHRAE Task Group developed a standard procedure for these calculations, known as the transfer function method (TFM). This method simplifies the cooling load and heating load calculations, and factors in all the other determinants that increase or reduce heat gain and heat loss. 0852c4b9a8
