FAQs about EAp2 :

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?

NC-v4 EAp2:Minimum energy performance

Definition of a Laboratory Space

I am working on a project which is a facililty that tests tools used in semi-conductor fabrication facilities. The spaces are clean rooms with strict control of temperature, humidity, and particulates. I am wondering, if clean rooms are considered to be "labs" under ASHRAE 90.1-2010/LEEDv4? Whether they considered labs or not will impact the Baseline system type and a number of other major inputs into the energy model. Unfortunately, I haven't been able to find a definition of "lab" in ASHRAE 90.1, the LEED reference guide, or in any of the LEED interpretations.

I think it qualifies as a lab if it meets the requirements of G3.1.1 Exception c. "For laboratory spaces in a building having a total laboratory exhaust rate greater than 5000 cfm, use a single system of type 5 or 7 serving only those spaces."
