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?

Automatic Receptacle Controls in 'open offices'

The following process load requirement for Automatic Receptacle controls mentions 'open office'. 

 "At least 50% of all 125 volt 15 and 20 Amper receptacles installed in private offices, open offices, and computer classrooms shall be controlled by an automatic device which functions on a scheduled basis, an occupant sensor, or a signal from another control system that indicates the area is unoccupied, in accordance with Section 8.4.2."

Is there a definition anywhere which will clarify what constitutes as an open office? We are a library project where we have an open plan with book stacks, reading tables and computer tables etc. Would this requirement be applicable here? 

Thanks!!

I don't think a library would be considered an open office. Did you look at the definitions in 90.1 to see if this is covered?

Hi Marcus, I looked in the 'definitions, abbreviations and acronyms' section in the ASHRAE 90.1-2013 read-only version I found online. Is there another place that I should look at? Thank you.

So if it is not defined by the standard it is up to the user and the adopting authority to define a particular term. An open office to me is a whole series of cubicles where an office function is being performed. A library will have an office or two but the rest of the building is clearly not an office. People in the library do not come there and spend all day there. They don't have a more or less permanent place there.
