I am working in projects in Mexico and it has been a challenge to model heating when we have none. Sometime when modeling heating comes out higher in the proposed design than in the baseline and t

This might be a rather simple question, but would like avoid confusion.

G3.1.2.10 says ER is needed when design cfm >5000 and more than 70% OA. I wonder does this mean the proposed or baseline design cfm? Our proposed design uses chilled-beam w/100% OA in the DOAS.

Hello All, I have two questions about compliance with the mandatory provision: 1) Only the main air conditioning system should be evaluated with the tables in chapter 6?

Our project is G+3 factory building and it is a major renovation and we are renovated wall, window, HVAC equipment and we consider ASHRAE 90.1.2007 Building envelope for base case & renovated

Greetings, We have a project, which is registered upon LEED-NC v2009, with unit type SI. The online form of EAp2 has a new form, which is directing us to upload the Minimum Energy Performance Calcu

We refer to ASHRAE 90.1 Supplementary Addendum i which discuss the LPD of tradable surface on table 9.4.5.

Thanks for the prompt and kind answer, Marcus. One more thing: Is it possible that baseline SHGC can be smaller than proposed one, even if both are below 0.25 (maximum)? Thanks

Our building energy model s.f.(table eap2-1) 74,000+/- does not match the gross building s.f. reported in 1.1A 94,000+/-. The difference is approximately 20,000 s.f.
