FAQs about EAc1.3 :

If pursuing Option 2, what is the scope of the energy model if the space shares a central plant, and what type of software should be used?

For Option 1, Zoning and Controls, is a thermostat considered an “active control capable of sensing space demand"?

We are a bit confused as to the meaning of space fan and pump sizing? Could anyone please offer some clarification? Thanks!

Hi Marcus, It is on the online form, under Equipment Efficiency, under section 1.4-Mechanical System Design Criteria

This section of Core Performance deals with designing the mechanical systems. There are a series of steps outlined in this section which must be followed and then documented to demonstrate compliance. What needs to be done is documented in the Core Performance document which you need to have a copy of to be able to demonstrate compliance.

We are looking at Option 1 - Equipment Efficiency under Core Performance Guide The reason is that all mechanical systems are in the basebuild and we were wondering whether the kW of the tenant space fan and pump sizing should be included or left blank? The system is a chilled ceiling system.

Now I see it. Only those components within the tenant scope of work need to be included. Anything within the base building systems that is already in place does not need to be addressed. This line clearly indicates tenant fan and pump sizing. If the fans and pumps are already there and are not part of the tenant scope of work leave it blank or indicate NA.

Thanks a lot Marcus! Much appreciated! Does the same apply for Table EAc1.3-1 under Criteria 2.9 regarding variable speed control?

I think the same principle applies - if it is not in the tenant scope of work you do not have to demonstrate compliance.
