[Equest-users] Humidification Savings for LEED, BREEM

[Bikesh Dahal via Equest-users]

Has anyone shown savings for atomizing humidifiers for LEED and BREEM Projects? I am working on an arts storage facility with significant humidification requirements. I would like to claim savings due to the atomizing humidifiers.
I am developing an exceptional calculation to demonstrate the savings. I was wondering if anyone has been able to claim savings for these either in LEED or BREEM certification?
Thanks a lot.

Subject: Re: [Equest-users] ER Wheel in Baseline

The amount of outdoor air in the baseline determines whether or not the baseline requires heat recovery. The amount of outdoor air in the baseline depends on the ASHRAE 62.1 outdoor air amounts or the mandated exhaust/make-up air flow – which ever is larger. Given that the space is a car garage, exhaust likely determines the baseline outdoor air amount.

By way of an example, I am working on a project that has 100% OA systems. They are VAV systems with the minimum flow equal to the 62.1 calculated value ramping to maximum flow for cooling. The proposed design has ERVs. The baseline outdoor air is equal to the 62.1 calculated values but the total supply flow is such that the percentage of outdoor air is less than 70% so the baseline doesn’t have heat recovery.

Hey Anthony,

I believe you're absolutely right. Because of this confusion I posted in the forum!
In my case, this is climate zone 5A. Supply Air is more than 5000 cfm per fan. And the proposed system is on 100% OA with HR wheel. It's for a car-repair bay/garage.
So you think the Baseline won't need an Heat Recovery Wheel? Should I be modeling it as even 100% OA?

Aru,

I may be reading the question wrong but the proposed case system does NOT dictate baseline case ERV requirements.  If the autosized baseline case systems meet the characteristics outlined in 90.1-2007(?) Section G3.1.2.10, then an ERV must be included on that system unless one of the exceptions apply.

Hi Aru,

Yes you are correct - you have to create an exhaust air heat recovery with at least 50% effectiveness in your baseline bldg.  Check out section 6.5.6.1 of ASHRAE 90.1 for further guidance.

Hello there,


In a 5A climate zone, I am working with a Proposed model with a RTU (30,000 CFM, 100% OA) with exhaust air ER wheel in it. I am kinda sure that I've to create a ER wheel for the 90.1 Baseline (as per G3.1.2.10). Just want to make sure if I am correct?

Help please. Thanks
