Page nine of the RFP lists senen (7) certifications. What types of training cover each certification? Envelope is listed twice; what does the stand alone Envelop mean?

The RFP lists the Building Performance Instutute's (BPI) certifications. These nationally recognized certifications require an individual to pass a proctored exam from a BPI affiliate, such as the NM Energy$mart Academy at Santa Fe Community College. BPI courses and NM Energy$mart trainings prepare individuals to pass thes tests, however, that training is not a substitute for the certification. 

BPI describes the two "Envelope" certifications as follows:

Envelope – quantify performance and prescribe improvements to help tighten the building envelope (shell), stop uncontrolled air leakage and optimize comfort, durability and HV/AC performance.

Residential Building Envelope Whole House Air Leakage Control Installer – implement measures to tighten the building envelope to reduce energy loss from air leakage and also reduce pollutants and allergens through air migration. Improve thermal comfort and energy efficiency through the proper installation of dense-pack insulation materials.
