What the process may include
Depending on the project, the process may include plan review, energy modeling, field verification, and final testing support.
Our 5-Step HERS Rating Process in Malden
From permit-ready planning to your final certificate, here is exactly how we guide Malden projects through HERS compliance — including the consulting step most raters leave out.
Plan Review & Preliminary Report
We start by reviewing your plans and issuing the preliminary HERS report your building department needs before a permit can be pulled.
Equipment Consulting
Before anything is installed, we confirm your appliances, HVAC and equipment are the right choices. Many companies skip this and just hand over a report — this step keeps you from buying the wrong gear.
Mid-Point Inspection
Once framing is done, we verify insulation and air sealing are installed correctly and to code, capturing what the HERS report depends on before drywall goes up.
Final Testing
We complete blower-door testing, duct-leakage testing and ERV balancing. Proper ERV balancing is critical, since an unbalanced system can create pressure problems throughout the home.
Final Certificate
Finally, we issue the signed HERS certificate to close out your building permit and set you up to apply for the Mass Save rebates you’ve earned.
Malden and the Massachusetts Specialized Stretch Code
Malden sits in Climate Zone 5A and is subject to the Massachusetts Specialized Stretch Code. Beyond demanding a tight, efficient shell, the code requires new homes to be prepared from the start for the solar and EV-charging upgrades many owners eventually pursue.
Solar-Ready Requirements
RB102 requires a Malden home to keep unobstructed roof area and spare service capacity, so a future solar array can be mounted and connected without major electrical work.
EV-Ready Requirements
RB103 calls for the charger conduit and panel space to be built in from day one, giving a Malden owner a ready circuit for an EV charger without cutting into finished walls.
Talk directly with the owner
Have questions about how the Stretch Code or rebates apply to your Malden home? You can talk directly with Dominic Zammuto, the owner and a registered Mass Save partner, who will walk you through your score and options before any work starts.
How to Read a HERS Index Score in Malden
A HERS Index score gathers all of a Malden home’s energy characteristics into one comparable number — the kind of figure you can set beside any other house, where lower always signals better performance.
100 as the anchor
A home built to the 2006 reference code scores exactly 100. Many of Malden’s older homes rate higher, a signal they use more energy than that baseline.
Aiming for 0
A score of 0 means the home makes as much energy as it uses across a year. Each step a Malden home takes toward zero shrinks its dependence on the grid.
Point by point
Every point stands for roughly one percent of yearly energy use, so shaving even a few points off a Malden home’s score shows up as ongoing bill savings.
The Measurements Behind a Malden Rating
We back every Malden score with real testing rather than estimates, joining predictive modeling to hands-on diagnostics so the rating reflects the finished home.
- Energy modeling: before building starts we model the Malden home’s envelope, systems and fuels to project the score and flag issues while changes are still inexpensive.
- Blower-door testing: depressurizing the house measures exactly how much air escapes the shell — a decisive factor for comfort and heating costs in Malden.
- Duct-leakage testing: we pressurize the ducts to locate conditioned air leaking into unconditioned zones and confirm the system passes code before we sign off.
Where HERS Meets the Stretch Code in Malden
Massachusetts writes the HERS rating directly into its energy code as a compliance route, so the score we produce frequently determines whether a Malden permit moves forward.
- Built on IECC 2021: the state Stretch Code adds efficiency requirements on top of the 2021 international code, and a qualifying HERS score is one accepted way to demonstrate compliance.
- Fuel choice moves the target: an all-electric Malden home is measured against a different score than a fossil-fuel home, so that decision shapes the design from the very start.
- A gateway to rebates: the same verified rating that meets the code also unlocks Mass Save incentives — you can check the latest terms on Mass.gov.

FAQ About HERS Rating Malden MA
Common questions about HERS ratings in Malden, Massachusetts.
What is a HERS rating?
A HERS (Home Energy Rating System) rating is the national industry standard for measuring a home's energy efficiency. A certified HERS Rater reviews the plans and performs on-site inspections and testing, including a blower door test, to produce a score. Lower is better: a standard new home built to 2006 code scores 100, while a net-zero home scores 0.
What is a good HERS score?
Any score below 100 beats a standard new home, and the lower the number the more efficient the home. A score of 50 means the home is about 50% more efficient than a standard new build, while older unimproved homes often score 130 or higher. Massachusetts code targets are now well below 100.
How have Massachusetts HERS requirements changed in recent years?
Massachusetts has steadily tightened the maximum allowable HERS score. The required score for new homes was around 55 in 2022, dropped to 52 in 2023, and tightened to HERS 42 for mixed-fuel homes and 45 for all-electric homes as of July 1, 2024. The 2023 update also adopted the 2021 IECC as the base code and removed the earlier 5-point HERS credit for rooftop solar, pushing toward efficiency and electrification.
How much does a HERS rating in Malden cost?
A HERS rating in Malden typically costs:
- Single-family homes: $1,850–$2,500
- Accessory dwelling units (ADUs): $1,600–$1,850
- Multifamily: $900–$1,450 per unit
Final pricing depends on home size, complexity, and the number of required site visits.
What HERS score do I need to pass in Malden?
As of July 1, 2024, new construction needs a HERS 42 for homes using any fossil fuel and a HERS 45 for all-electric homes, verified by a certified RESNET HERS rater. 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 triggers a HERS rating in Malden?
New construction almost always requires one. Under energy code Section R502, an addition triggers a HERS rating when the added conditioned floor area exceeds 1,000 square feet or doubles the size of your existing conditioned space (more than 100% of the existing conditioned floor area), requiring the combined dwelling to meet the maximum HERS ratings in Table R406.5.
Do renovations or alterations require a HERS rating?
They can. Under Section R503, extensive alterations (or IEBC Level 3 alterations) that exceed 1,000 square feet or double the size of the existing conditioned space (over 100% of the existing conditioned floor area) must meet the maximum HERS ratings in Table R406.5. Smaller alterations must still meet component requirements for insulation, replacement windows, water heating, and lighting.
Do I need a HERS rating in Malden?
If Malden has adopted the Massachusetts Stretch Energy Code, then yes for new homes, larger additions, and extensive renovations. A certified HERS rater can confirm whether your specific project triggers the requirement.
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 tighter values. For replacements specifically, Section R503.1.1.1 requires new units, including sash and glazing, to meet the U-factor and SHGC in Table R402.1.3.
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 about 3 points, saving close to $20k or more between systems and upgrades.
What is an ERV system and do I need it in Malden?
Yes, it is now required by code. You can use an ERV or HRV to satisfy the requirement for balanced mechanical ventilation.
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.
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 such as the washer, dryer, dishwasher, and fridge.
Does a HERS rating add value to my home?
Yes. Energy-efficient HERS-rated homes have been shown to sell at a premium over comparable standard homes, on top of ongoing savings from lower utility bills.
Are there rebates for a HERS rating in Malden?
Yes. Working with a certified HERS rater can unlock Mass Save incentives for new construction and renovations.
Where can I find a HERS rater near Malden?

HERS Score Requirements in Malden by Year
Massachusetts Stretch Energy Code HERS thresholds have tightened over time. These are the maximum HERS Index scores required to pass for new construction, based on when the building permit was filed.
| Time Frame | Required HERS Score |
|---|---|
| 2022 | New homes: HERS 55 or lower |
| Effective Jan 1, 2023 | New homes: HERS 52 or lower |
| Effective July 1, 2024 (current) | HERS 42 for homes using any fossil fuel; HERS 45 for all-electric homes. Using the embodied-carbon trade-off path, the targets relax to HERS 45 (mixed-fuel) / 48 (all-electric). |
| Major remodels, additions & change-of-use | Generally HERS 65 to 75 |
| ADUs (per recent updates) | Around HERS 52 mixed-fuel / 55 all-electric |
Viewed year by year, the Malden requirement has ratcheted steadily tighter. New construction passed the 2022 code at HERS 55, dropped to 52 in 2023, and since July 2024 must reach 42 for any fossil-fuel home or 45 for an all-electric one. Since the code is applied by permit date, a Malden plan drawn to an earlier, gentler number can fall short now — so we calibrate every energy model to the exact standard the permit triggers.
