For additional information search for or find a copy of a December 2001 ASHRAE Journal article by Wagdy A.Y. Anis, AIA titled " The Impact of Air Tightness of System Design." A couple of other resources are: NISTIR 7238 June 2005 titled "Investigation of the Impact of Commercial Building Envelope Airtightness on HVAC Energy Use," and a research paper titled "Multizone Airflow Models for Calculating Infiltration Rates in Commercial Reference Buildings" by Lisa C Ng, Amy Musser, et. al. dated 25 November 2012 published by Elsevier: http://www.elsevier.com/locate/enbuild.

Chapter 2 of the COMNET Modeling Guidlelines & Procedures (MGP) Manual is a good place to start. The COMNET Manual can be downloaded from the following link: http://comnet.org/mgp-manual. In addition the NREL Technical Report publication NREL/TP-5500-46861 "US Department of Energy Commercial Reference Building Models of the National Stock" is an excellent resource. You can perform a Google search of the publication number above and go right to the document or use the following link: http://www.nrel.gov/docs/fy11osti/468.... Chapters 4 and 5 in this report give you a very detailed description of the author's approach to developing an energy model and the information required before starting a model. Enjoy your research.

There are three primary sources for energy modeling schedules I am aware of:

1. ASHRAE 90.1 User's Manuals (based on 90.1-1989)
2. Commercial Reference Building Models of the National Building Stock (NREL/TP-5500-46861)
3. The COMNET Manual.

If you are already familiar with the ASHRAE schedules you should review the the NREL Technical Report publication NREL/TP-5500-46861 "US Department of Energy Commercial Reference Building Models of the National Stock." Their schedules can be found in Appendix B of that publication. You can perform a Google search of the publication number above and go right to the document. Be sure to read the documentation in the report about the schedules. The reports authors started with the 1989 ASHRAE 90.1 User's Manual Schedules and modified them based on their knowledge and experience.

The COMNET Modeling Guidelines & Procedures Manual (MGP) can be downloaded form the following link: http://www.comnet.org/sites/default/f.... You will find the schedules in Appendix C in that publication. These are a great starting point and can always modified as needed for any specific building type or user specific needs. I hope this helps.
