FAQs about EAp2 :

Are there any exceptions to the daylight control requirement of ASHRAE 90.1–2010?

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

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?

Does the base building information need to be included in the minimum energy performance calculator, or is it sufficient to just include the tenant space?

CI-v4 EAp2:Minimum energy performance

Water heating equipment

Hi, 

We have a CI project and we are specifying a 18 kW tankless electric water heater, table 7.8 from ASHRAE 90.1-2010 does not specify any requirements for this type of heater as it does not a storage capacity. However the technical data sheet indica an 98% efficiency but not an SL. Can we consider this as it does not have minimum performance requirements and do not include it in the mandatory requirements?

Thanks in advance 

Kind regards

Yes any equipment not covered by the standard is exempt from the mandatory provision for efficiency.
