FAQs about EAp2 :

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Our process load is higher than 25%. Do we have to justify that?

Do I need to justify the electrical and fuel rates I am using in my model?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Can I claim exterior lighting savings for canopy lighting even though a baseline model cannot include shading elements?

The project is built on a site with existing exterior lighting installed. How should this be accounted for?

NC-2009 EAp2:Minimum Energy Performance

Kindergarten restooms w/ no occupancy sensor-OK or huge problem?

discovered a potential oversight on a building design: some restrooms intended to be used by very small kids are equipped with light switches and no occupancy sensors. This appears to put the project out of compliance with section 9.4. Is there any safety exception for this? The intention was that the kids would possibly get scared if the lights go off and chaos would ensue possibly comprising safety. All the other restrooms have occupancy sensors. Additionally, sometimes adults need to help very young kids use the restroom, which is similar to rendering "patient care." Looking for feedback: Think we need to suck it up and put in occupancy sensors or is it OK in this limited circumstance (kindergarten single-occupant restrooms)?

I do not think it would qualify for the exception. Are all other lights in the facility controlled by occupancy sensors and that is how you are complying with 9.4.1.1? If so then yes that should be installed. If centrally controlled then you do not need sensors in these restrooms.

Thanks, Marcus. Right, all the other lights are controlled by occupancy sensors. Your feedback has been extremely helpful.

Occupancy sensor technology has improved dramatically in the past several years. Consider using a system with dual technology; for instance with movement detsection and infrared detection. This wil lhelp keep light sfrom going out with someone sitting still and avoid the potential panic situation you described. Your MEP engineer should be able to advise you about the range of technologies available.

Marcus, I'm having difficulties with an EA Credit (Green Power). I'm using LEED 2009 for Core & Shell Development. 1- I've provided the Green Power Summary info which was taken from our electric provider's print out. 2- Uploaded our proof of contract with energy company 3- Selected Option 1- Whole Building Energy Simulation This section has kWh values that were pre-loaded from another section (EAp2) but I have no idea how they're getting the"Total Electricity Use?" Any assistance would be GREATLY appreciated!

What version of the forms are you using? If it is not coming from the total electricity used for the whole building you may be using v3 which had a table where you reported the breakdown of the core and tenant energy use. Maybe it is coming from there.
