Certified HERS Ratings

It's in our name because this is our bread 'n butter. HERS stands for Home Energy Rating System. A Home Energy Rating involves onsite inspections and an analysis of a home's construction plans. A software tool is used to perform an energy model of the home's initial design and the final built conditions. The HERS rating results in a Certificate and with an index (like a score) that shows the market how great your home performs.

Option 1 : Streamlined

For the highly organized 'dialed in' projects:

Give us all your project specs and we'll provide the best HERS rating service available. Of course we're available for technical support and remote consulting as needed. Starts at $1100 

Option 2: Detailed support needed

This approach is for those that need a higher level of consulting to adjust the home design for energy code compliance, or to optimize for energy performance and budget driven goals.

We will provide insights on thermal boundary design, specific product recommendations, and will complete several energy model scenarios to present the cost/benefit analysis for various options. This option includes a higher level of remote consulting that is often needed to meet new energy code requirements for owner-GC's and builders new to the current code climate. Starts at $1,400

**HERS Ratings include all energy code and rebate program administrative requirements. 

Multi -family and 3+ single family projects.

Pricing is greatly reduced and is custom to each project.  email your plans for a quote. Pricing can be as low as $500/unit. 

What is a HERS Rating?

HERS Rating process:

1: Pre Construction :  Introductory meeting, preliminary HERS rating from plans, review of results, technical support.

2: During Construction site visit  - Insulation and duct inspection, air-barrier checklists (if required), continued technical support.

3: Post Construction site visit - Visual inspection and diagnostic testing, HERS certificate is generated, administrative requirements completed for incentive programs.

Visit here for more descriptions of HERS Ratings from RESNET.

Our process is streamlined and without hidden fees

We use tools such as Sketchup and mobile forms to complete the energy model for your project. We understand that as the project is built, there will likely be deviations from the original design.

Sketchup enables us to accurately and efficiently update the energy model through the building process.  Unlike other HERS raters that charge extra if your plans change, we don't because we can very efficiently make the changes.  

We maximize your rebates

The Massachusetts and Connecticut rebate programs require a certified HERS rating. We will handle all of the paperwork and will communicate clearly to ensure you receive the maximum rebates available. 

The Mass Save New Homes program is dramatically shifting for all projects completing after June 30, 2017. Most projects will result in a reduced rebate

Mass Save New Homes Program

If you are building a new single family or multi-family home, this incentive program is a no-brainer. Don't be put off by the administrative requirements. We will hold your hand through the entire process until you receive a nice check. A certified HERS rating is required in addition to sections of the Energy Star Thermal Enclosure System Rater Checklist

As a Certified HERS Rater, we are approved to deliver the following incentives through the Mass Save Residential New Construction Program.

2017 - all projects completing  after July 1, 2017

The Massachusetts utilities are shifting the incentive structure from a tiered system to a 'Blended Savings Approach'. Projected energy savings are calculated from HERS rater software. This is expected to result in reduced rebates for nearly all projects. As energy codes require more efficient homes, utilities are increasingly limited by the level of savings they can claim through the new construction rebate program.

Rebates are calculated as follows:

Participant Incentive = A * kWh + B * MMBu + C * %Savings

A= $0.35/kWh   B= $35/MMBtu    C= $3,000 single family project (1-4 Units)  = $2,000 multifamily (5+ units)

Program requirements as detailed in the Application still apply. 

 

Mass Save Mechanical System rebates 

For projects finishing after June 30, 2017,   mechanical system rebates are not available on a per unit basis. These system rebates are bundled into the savings calculated in the Blended Savings equations. 

System rebates may be available through other programs, such as the MassCEC. However applicants should be aware of 'double dipping' in more than one Mass Save program. 

Contact us for a full overview of incentives as they pertain to your project.


Connecticut Residential New Construction program

In the performance path, there are three tiers of incentives based on a confirmed HERS index. The  program requires a confirmed HERS rating and is very straight forward. 

  • Tier I :   HERS 70 - 61      $3,000
  • Tier II :  HERS 60-50       $4,000
  • Tier III:  HERS <50           $4,500 + $50 per point below 50

Additional rebates are available for Energy Star Certification and additional high performance building certifications.   Multi-family rebates are slightly lower and are allocated per unit. 


Blower Door testing

AIrtightness testing is required for the 2012 IECC and 2015 IECC energy codes. All homes need to be tested an confirmed to have a leakage rate of <3 ACH50 . Air Changes Per hour at 50 pascals (ACH50) is determined with this equation:  

ACH50 = (CFM50 blower door reading * 60) / Volume of conditioned space

A blower door test and airsealing inspection before the sheetrock is installed is recommended if there is any doubt that the air leakage target will be met. 

Duct Testing

2012/2015 IECC CODE and the 2017 STRETCH CODE REQUIRES ONE OF THE FOLLOWING 3 OPTIONS:

  • At rough-in, air handler not installed:
    Duct Blast Test Ducts Only
    Max leakage 3 cfm per 100 sq ft. of conditioned floor area

  • At rough-in, air handler installed:
    Duct Blast Test w/ indoor unit
    Max leakage 4 cfm per 100 sq ft. of conditioned floor area

  • Post-Construction, total leakage:
    Duct, Registers, Indoor unit
    Max leakage 4 cfm per 100 sq ft. of conditioned floor area

Ventilation testing

Ventilation testing is required for all rebate programs and the 2012 and 2015 IECC energy code (Mass amendments). This simple test confirms that the ventilation system - programmable bath fan or balanced HRV/ERV system, is drawing enough air to meet the ASHRAE 62 standard.

New Construction

As your HERS Rater we support you in building an energy efficient home while ensuring code compliance and that all available rebates are leveraged.

Projects we work on range from high performance custom homes to subdivision developments. The scope of our involvement ranges from basic code compliance testing to assisting with thermal boundary and mechanical system design before construction begins.
