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?

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?

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?

CI-v4 EAp2:Minimum energy performance

Clarification regarding domestic electric water heaters

Hello everyone,

We have a ID+C project outside the US, and client wishes to purchase a electric tankless water heater (www.termotronic.com).

It is about 11,000 W rated power and 99% efficiency. However, we are not sure if it is indeed eligible for Energy Star or not since there is a category for water heaters; that is, should we include it in the calculations for EAp2 credit as "Non-ENERGY STAR Equipment"?

Reviewing the ENERGY STAR® Program Requirements - Product Specification for Residential Water Heaters - Eligibility Criteria Version 1.1, item 2)B., it does state that Electric resistance water heaters are not eligible for ENERGY STAR.

Thank yuo very much for your attention on this matter!

Regards, 

CD

It is not eligible for Energy Star since they do not have a category that covers it. It is not included as "equipment" either since it is regulated by 90.1 as a separate end use under service hot water.
