The Reschexpert blog aims to keep you up to date on all happening of how the IECC 2021 affects Rescheck, Comcheck, Manual J, Manual S, Manual D.
In past codes like the IECC 2018 and IECC 2015 internal energy usage has focused more one one fixture, the lighting, and all the controls. Now the talk is about the plugs themselves. From having new homes ready to support the additional loads of electric vehicles to looking at the usage of individual plugs within the homes a new component is being conceived that will work in line with Rescheck, Manual S, and other home energy reports.
The next area that is continually sharpened is the R and U values on projects. The push to make buildings last longer into the future has plans being laid for homes built today to last well into 2100 and beyond. What do we think about the 2102 energy code? Read here. Just kidding.
New Duct Leakage Testing will be of special interest to the Do it Yourself Home energy audit crowd in how they prepare Manual S Equipment sizing, and Manual D Duct Layouts. These new standards are on the way in the newest IECC 2021 code and will no doubt have impact on all ACCA Manual D Duct Layouts and Duct Sizings.
In older IECC codes it was sometime possible to trade off renewable energy for building a less efficient home. I never understood why someone would want to pay the high price of renewable energy then skimp on the low cost of insulating a home correctly, but we do see some interesting projects on a daily basis. Basically, this practice would end and to that we say, good riddance.
One of the most exciting areas for the home energy buffs is that they are going to allow the use of more IECC 2021 approved softwares. We stay abreast and run all the latest home energy audit softwares at our energy lab and hope to be able to use more and more of them as the IECC 2021 is brought to fruition.
The next meeting we plan to frequent and attend is the 2019 Public Comment Hearing Schedule:
The schedule for the 2019 Public Comment Hearings to be held at the Rio Hotel and Convention Center on October 23 – 30 is now posted. The Public Comment Hearing Agenda is scheduled to post on September 4.
You can download the schedule for this event here.
If you as a builder, architect, engineer, or Do it yourself home energy auditor would like us to present or ask anything to the public hearing we simply as that you email us at firstname.lastname@example.org. We are here to provide you the most relevant info on IECC 2018 and the transition to IECC 2021.
