Dear All
In the context of a new airport project pursuing LEED certification, a chilled water plant will distribute chilled water to the whole building, including some retail tenancy areas (to be fitted out by the tenant). The embedded electricity associated with space cooling of these retail tenancy areas accounts for much less than 10% of the total annual consumption of the building.
The question is: is it mandatory to install enthalpy meters in each of these tenancy retail areas? Or they can be exempted due to its low relevance (<< 10% of the total annual consumption of the building)?
Thanks in advance,

Metering is by energy end use, not by space type or area, so since space cooling is greater than 10% the space cooling must all be metered. Is it a major problem to do so?

Marcus,
What exactly is to be metered? Is it the electricy used by chillers (on the building scale)? Is it indivudual BTU meters at each individual tenacy? Is it HVAC as a whole (chillers, pumps, etc.)?
Thank you,

You would typically meter the building by energy end use. Energy end uses tend to be the individual systems reflected in the energy modeling results like lighting, heating, cooling, pumps, fans, service hot water, plug loads, elevator, etc. So exactly what you meter depends on the systems within your project.
