Combining spaces into thermal zones in e+ and OS A few related questions about combining multiple spaces into a thermal

VRF in CBECC-Com is coming very soon. The functionality was added some time ago (on an internal development branch), bu

For CA Code compliance, my (unofficial) interpretation is:

• For Exterior Systems: this would be considered a process load and therefore it is not required to be modeled. If there is a boiler or other system used to generate HW for the radiant loop, that system would still need to comply with any mandatory or prescriptive requirements
• For Interior Systems: radiant systems are not natively supported, so if you were to do an exceptional calculation, it would only impact the Proposed Design. The Baseline would still use the ACM system map to define its HVAC system.

How should I setup a glazing system in E+ to model an electrochromic glazing system? The glazing should be "clear" when the solar heat gains are low, and "dark" when the heat gains are high. Additionally, the glazing's "darkness" should be variable such that the interior spaces can still maintain the daylighting setpoints (i.e. glazing properties are controlled by daylighting sensor).

Has anyone developed a reasonable method of modeling aDsorption chillers in E+? I have reviewed the Input/Output reference and see that there are a few ways to model aBsorption chillers but not adsorption. I'm curious if the performance could be approximated with alternate performance curves? However, since they are different processes, I question whether this is a viable approach. The Chiller:Absorption and Chiller:Absorption:Indirect objects seem to be steam-driven whereas an adsorption chiller is hot water driven.

If anyone has come up with an approach for adsorption chillers that is reliable and represents the system performance, please let me know.
