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?

Good day, I need to understand some thigs about 5.4, 8.4 and 10.4 of standar ashrae 90.1-2007.(My project is in Perú) 5.4- 5.4.1-'' Where insulation is required in 5.5 or 5.6, it shall comply with the requirements found in 5.8.1.1through 5.8.1.9'' - I am using curtainwall, so, 5.8.1.1-5.8.1.9 has become mandatory. 8.4- " Feeder conductors shall be sized for a maximum voltage drop of 2% at design load'', but in my country is 2.5%, I need to comply ashrae of can be the law of my country. 10.4- ''Electric motors shall comply with the requirements of the Energy Policy Act of 1992 where applicable, as shown in Table 10.8. Motors that are not included in the scope of the Energy Policy Act of 1992 have no performance requirements in this section''. Seeing Energy Policy Act of 1992, it is for U.S. , but my project is not there, so I need to comply it) thank you in advance

5.8.1.1-5.8.1.9 deals with the characteristics of the insulation and not curtainwall. But yes those sections become mandatory related to the insulation. 8.4 - if your country's requirements are different you are fine. This item is not even evaluated in a LEED submission. 10.4 - the one affects energy use directly and if you cannot comply you will need to make a compelling case as to why you cannot comply.
