How can a modular home earn the ENERGY STAR?Ī home earns the ENERGY STAR by meeting strict program requirements for energy efficiency set by the U.S. These pre–built sections are transported to the building site and constructed by a builder to meet all applicable building codes for site–built homes. Projects may not use Appendix G from ASHRAE 90.1-2016 if they are using the 20% or 25% Performance Target Options.ĮNERGY STAR Certified Modular Homes What is a modular home?Ī modular home is a prefabricated home that is made of multiple modules or sections that are manufactured and substantially assembled in a manufacturing plant.
Projects using Appendix G from ASHRAE 90.1-2016 must use the Performance Path Calculator_AppG2016 and Simulation Guidelines_AppG2016. Projects pursuing targets based on ASHRAE 90.1-2013 or later must use Appendix G from ASHRAE 90.1-2016.
To determine the code adopted by the state and its effective date, please visit the Status of State Energy Code Adoption Web page. The permit application or issue date will be used to determine what state code was in place in the state. In an instance where the building is permitted under a local code that is not the same as the state code, the Performance Target is based on the state code in place.
Local Code Exception: While local city or town codes may differ from the state code, the determination for the ENERGY STAR program is based on the commercial code adopted by the state, not the local jurisdiction.Appendix G from ASHRAE 90.1-2016 must be used.These Performance Target options may not be used for projects using Appendix G from ASHRAE 90.1-2016.Appendix G from the referenced ASHRAE Standard or from ASHRAE 90.1-2016 may be used.Performance Target Options: Savings (%) above varying ASHRAE 90.1 Baselines Projects in states that have adopted as the commercial code the 2012 IECC, 2015 IECC, 2018 IECC, ASHRAE 90.1-2010, ASHRAE 90.1-2013, ASHRAE 90.1-2016, or equivalent, will be required to meet a Performance Target of 15% better than the energy code under which the building is permitted, unless choosing one of the equivalent options in the table below. All other projects must meet the national requirement of 15% over ASHRAE 90.1- 2007. For the ASHRAE Path, determine the commercial code in effect in your state and then choose from the Performance Target options in the table below.
