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?

Hi 

I'd like to know if digital media screens located outside the project building also need to comply with light pollution reduction requirements i.e do not exceed a luminance of 200 cd/m2 (nits) during nighttime hours and 2000 cd/m2 (nits) during daytime hours ? 

Also should the Power consumption be included as part of "process" as it for advertising, or under Lighting (LPD) for Energy modelling ?

There is an exemption for this type of lighting for uplight and tresspass. Will these be automatically turned off after business hours and will this project be located in LZ3 or LZ4? Under LEEDv4 the following exterior lighting is exempt from the requirements, provided it is controlled separately from the nonexempt lighting:
  • lighting for theatrical purposes for stage, film, and video performances

The sign lighting is exempt so it becomes a process load modeled identically in both models.
