FAQ About Stretch Energy Code Support in Plymouth
Common questions from homeowners, builders, and developers in Plymouth, Massachusetts.
How much does a HERS rating in Plymouth cost?
A HERS rating in Plymouth typically costs $1,600–$1,850 for an ADU, $1,850–$2,500 for a single-family home, and $900 per unit up to $1,450 per unit for multifamily depending on how many units you have.
What HERS score is required in Plymouth?
For new construction a single-family home needs a HERS score of about 45 with gas or 45 all-electric. Low-emission concrete comes in around 45 with gas or 48 all-electric. An ADU is 55 all-electric or 52 with gas, and multifamily matches the single-family requirement.
What kind of insulation do I need to pass a HERS rating?
You generally need around R-21 to R-30 depending on whether you go gas or all-electric.
What if I do not want to use spray foam?
You can use exterior insulation and then use mineral wool inside the wall.
How can I build to energy code in a cost-effective way?
Using low-emission concrete can reduce the HERS score by 3 points, saving close to $20k or more between insulation and windows.
What kind of windows do I need to meet the new energy code?
All-electric homes favor a U-value of .25/.26 with an SHGC of .42 or higher, while gas homes favor triple-pane windows with a U-value of .20 or lower.
What is an ERV system and do I need it in Plymouth?
Yes, you need an ERV system — it is now required by code. You can use an ERV or HRV to satisfy the code.
How much CFM do I need for my ERV?
It is based on bedrooms, square footage, and insulation volume, along with the ACH from your blower door test. The system is balanced after the blower door test.
What do I need to start a HERS rating?
You need a set of architectural plans and to know whether you will go gas or all-electric.
How can I improve my score and what affects my score?
Your score is affected by windows, insulation, HVAC, and appliances (washer, dryer, dishwasher, fridge, stove), plus a wifi thermostat and low-flow faucets.
