[Bldg-sim] Parking Garage Controls

[Jackson Luckett]

Saif,
Appendix G dictates the adjustments for lighting controls. Can either be through power reduction or schedule modification.

Ha, whoops, obviously I skipped over the ASHRAE section that Saif referenced that made it obvious he was talking lighting controls. For what its worth, the ESMFHRSG I linked to previously also has guidance on appropriate lighting power reductions to represent occ sensors, etc. However, as pointed out previously, that guide is written for multifamily projects so the guidance probably isn’t appropriate for office.

Hi Jackson,

I want to model the parking garage controls lighting, which includes occupancy sensors and daylighting harvesting for LEED 2010 project. I tied LEED user, but the only thing I was able to find is a different approach to meet the occupancy sensors. Although these controls are applied the same for the proposed cased and proposed model, I think we cannot use the 24/7 parking garage schedules any more, so I am looking for an approach to model these controls

Best,

Hey guys,
Not sure if the question is referring to lighting controls or ventilation.
I would recommend searching through these forums to see if it can help:
https://leeduser.buildinggreen.com/search/site/parking%20garage%20control

Depending on your local code requirements and interpretation of the language will dictate whether it is considered a process load or not. If it is ventilation, you will most likely have to show a hand calculation depicting the fan run time hours with an exceptional calculation if you are going for energy savings.

Cheers,
Jackson

Thank you Nathan, the project I am on is a high-rise office building in Austin

Not sure what your project type is, but for multifamily residential applications, the Energy Star Multifamily High Rise Simulation Guidelines give some rules for garage exhaust modeling per 90.1 2016. See section 6.6.2 of this document:

Hi everyone.

I am trying to model parking garage controls required by ASHRAE 90.1 2010 Section 9.4.1.3. What would be the best approach to model these controls? Is there a published study that suggests a certain power reduction or schedules when using these controls?

Thank you,
