[Equest-users] District Cooling

[Howe, Timothy]

Make sure the Billing unit thermal value is correct.  It defaults to 1,000,000 Btus as the unit of measurement.  If the utility rate is in Ton-days, say 3.50 per ton-day then you need to change that number to 288,000.
 
1 ton = 12,000 btuh
1 ton-day = 12,000 btuh * 24 hours = 288,000 btus

Short answer YES!

 

In brief you will connect your building to a chilled water loop and put an energy meter on the loop to calculate the amount of energy used. You can then add an energy rate to the chilled water meter to calculate your annual cost.

 

However, if this is a LEED building registered in LEED NC v2.2 (and some other versions) after May 28th 2008 you MUST use the LEED document "Required Treatment of District Thermal Energy..." which will significantly change how your project will be modeled.

Hi guys!

Can we model a project being served by a District Cooling Plant in E-quest?

More thanks in advance.

Wallie
