Hi, I am currently working on a school project located in KSA. we are about to start the EA P2 and C1.

There are currently two ASHRAE AEDG versions available, one if for 30% savings over ASHRAE 90.1-1999 minimum and the other is for 50% savings over ASHRAE 90.1-2004 minimum.

I'm not sure if this belongs here or in EC1. This is for a LEED-S 2009 renovation project with an addition. We have updated our energy model input based on the initial design review comments.

Does the LEED AGMBC require to have totally separate building systems so that the energy-related points can be clearly defined? My project has centralised Energy center which will be supplying chi

The baseline U-values proposed by ASHRAE 90.1-2007 for a building with high thermal mass in climate zone 1 (see below extracted from table 5.5-1) seem to be too low-performing. Are these correct?

I'd like to understand better how to input what is needed in Table L-1 for our solar thermal system (our solar PV system was easy to input).

Dear all, I am currently filling the LEED Online Letter templates. Some of these are BETA version.
