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.

Bikesh,
Keep in mind that the atomizing humidifier has an evaporative cooling effect. The heat to vaporize the water has to come from somewhere. If the humidifier doesn?t heat the water, then the heat comes from the airstream that the pressurized water is squirted into. So during the heating season there wouldn?t be much savings, if any. The heating coil needs to add more heat to the airstream to make up for the evaporative cooling. The net result should be pretty close to break-even.
There is energy savings during the cooling season, if the humidifier runs during the cooling season. The evaporative cooling reduces the cooling load at the cooling coil. With a heated humidifier the heat adds to the cooling coil load.

Hi Bikesh,
As per me if the arts storage requires humidification then it is climate
dependent to have achieve the target of having energy savings.
It would depend upon the system and design set-points to show how savings
can be achieved.
For this one requires to have the set-point slightly below the required
cooling set-point. After the water small droplets are atomized it is
certain to achieve small amount of energy saving depending upon the climate
and the maximum and minimum humidity required to be maintained.
My theory is as per some hypothetical climate zone which is warm and humid
or dry.
The concept behind the energy savings can be the latent heat of heating of
water droplets.
.
The water droplets will absorb the heat of the air and make it cooler and
also the storage system might require high level of humidity.
As per me for the exceptional calculation you will have to have the
parametric runs with the maximum and minimum humidity to show the exception
based calculation on the basis of how the humidity factor is causing the
energy savings to be achieved.
Following can be the problems with the target:
1.The climate having low temperature all over the year so the purpose is
not achieved.
2. The climatic condition is highly humid so the de-humidification and
humidification will cause exceptional losses.
3. To achieve the energy savings you can be required to moderate the
maximum and minimum amount of relative humidity the parametric runs.
4. If you are going as per LEED or BREEM, the you are required to have the
humidity maximum and minimum as per the guideline.
Hope this may help.
For more support other can have help.

Hi Bikesh,
My clarifications are as follows:
