HIS & HERS Energy Efficiency provides exceptional building performance services.
We will help you build a better building  cost effectively. 

As a small shop that uses efficient tools for energy modeling and data collection,
our rates are among the lowest in the Northeast region. HERS ratings from $500

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 analysis of the home's initial design and the final built conditions.

Our Certified HERS Ratings for single family and multi-family buildings include technical support for your team. We are lazer focused on making the incentive program and code compliance process easy for you. We use Sketchup to create a 3D model of your building as a tool to communicate through the construction process.

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.

Contact us for our pricing schedule and a more detailed description of the HIS & HERS process. 

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 our 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.  

Consulting is included

Still deciding on insulation or heating equipment? No problem.
We are happy to help you consider the options.

The earlier you get us involved on the project, the better. If you want to hit the highest rebate tier, but are unsure of how to do that we can model a few design scenarios and determine the most cost effective way to hit a performance target. While other HERS raters charge for this service, we consider it our job and enjoy helping clients build better homes. 

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. 

NOV 2016 UPDATE
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.

2016 Mass Save New Construction Single-Family rebates

  • Tier I : $750, high efficiency mechanical system rebates, free CFL/LEDs, HERS fee discount.
  • Tier II: $1,250, high efficiency mechanical system rebates, free CFL/LEDs, HERS fee discount
  • Tier III: $4,500, high efficiency mechanical system rebates,  free CFL/LEDs, HERS fee discount


2016 Multi-family rebates

  • Tier I: $650, high efficiency mechanical system rebates, free CFL/LEDs, HERS fee discount
  • Tier II: $1,150, high efficiency mechanical system rebates, free CFL/LEDs, HERS fee discount
  • Tier III: $2,000, high efficiency mechanical system rebates, free CFL/LEDs, HERS fee discount
    Rebates are per-unit. 

Mass Save Mechanical System rebates 

For 2016, all Tier levels can leverage mechanical system rebates. 

Download current offerings here [PDF].   We handle all of the admin and can assist in guiding your HVAC design for excellent performance, highest rebates, and lowest (better) HERS score. 

 

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

2009 IECC & STRETCH CODE REQUIRES ONE OF THE FOLLOWING 4 OPTIONS**:

  • At rough-in, air handler not installed:
    Duct Blast Test Ducts Only
    Max leakage 4 cfm per 100 sq ft.

  • At rough-in, air handler installed:
    Duct Blast Test w/ indoor unit
    Max leakage 6 cfm per 100 sq ft.

  • Post-Construction, leakage to outdoors:
    Blower Door/ duct blast test
    Max leakage 8 cfm per 100 sq ft.

  • Post-Construction, total leakage:
    Duct, Registers, Indoor unit
    Max leakage 12 cfm per 100 sq ft.

2012 IECC 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.

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

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

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 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.
