Important Considerations
Codes and Regulations
Minnesota Rule 7670 covers building energy efficiency calculations.
Minnesota Rule 1322 will replace Rule 7680. It is currently available only as an internal draft.
Specifications
This criteria is applicable to many specification categories including:
07 20 00 (07200) Thermal protection 08 50 00 (08000) Windows and doors 11 31 00 (11450) Residential appliances 26 50 00 (16500) Lighting
The information above refers to the Construction Specification Institute's (CSI) MasterFormat. The numbers listed above refer to some of the most relevant but not all of the possible MasterFormat sections related to this strategy. The 6-digit numbers refer to the newer 2004 MasterFormat edition. Numbers in parenthesis refer to the older 1995 edition.
