2018 IECC BASE ENERGY CODE<\/strong><\/h2>\n

Massachusetts has a base energy code that all new buildings in the state must follow. It is based on the most current version of the International Energy Conservation Code (IECC) which\u00a0establishes a baseline for energy efficiency by setting performance standards for the building envelope. Provided the mandatory requirements are met, the rest of the code can be met by either following the prescriptive or performance path.<\/p>\n

Performance Path Compliance:<\/strong><\/span><\/p>\n

The performance path requires energy modeling to demonstrate that the building as a whole uses equal or less energy than a home built to the prescriptive path. Even though the performance path is slightly more involved, it allows flexibility to trade off many of the high-cost assemblies required in the prescriptive path resulting in substantial savings.<\/p>\n

To comply with the Performance Path, you will need either a simulated energy performance analysis or an Energy Rating Index (ERI) analysis. The ERI path, specifically a certified RESNET HERS Rating, is the performance path most often used to achieve energy code compliance in base energy code communities.<\/p>\n

We highly recommend following the Performance Path\u00a0utilizing\u00a0a HERS Rating<\/a>. \u00a0A HERS Rating is the most realistic compliance option that offers documented energy savings while giving you more flexibility and \u201ctrade offs”.<\/i><\/p>\n

Prescriptive Path Compliance:<\/strong><\/span><\/p>\n

The prescriptive path requires that each component is built to a specified R-value or U-value found in the prescriptive table. While the prescriptive path is a traditional approach and can be achieved without the aid of any software, it does not have much flexibility and therefore does not allow trade-offs to lower assembly cost.<\/p>\n

To comply with the Prescriptive Path, you will need:<\/p>\n
