Energy Star Multi-Family New Construction Requirements and Verification

Priority Energy HERS Raters provide verification and certification for multi-family buildings wiching to attain Energy Star certification. 

Energy Star Multi-Family New Homes Nation Program requirements

Energy Star Single Family New Construction Design Requirements

Energy Star compliance (currently Version 3.1, version 11) must be determined at the Design stage using Energy Modeling software. The certification process provides flexibility to select a custom combination of measures that are equivalent in performance to the minimum requirements of the ENERGY STAR Reference Design Home. Our software will determine the ENERGY STAR Energy Rating Index (ERI) Target, which is the highest ERI value that each rated home may achieve to earn ENERGY STAR.  Additionally, certain mandatory requirements apply. 

Note: Design requirements vary by Climate Zone (CZ). These requirements pertain to CZ 5 and the greater Chicagoland area.  

  • Builders are required to sign an ENERGY STAR Partnership Agreement and complete the online Version 3 Builder Orientation, which can be found at http://www.energystar.gov/homesPA
  • Building design must include fully aligned air barriers, reduced thermal bridging and air sealing that meets the Energy Star specifications. Specs can be found on the National Rater Field Checklist. (Priority Energy can provide this and review it with Builder.)
  • Builders must have HVAC Design Reports to include Manual J/D/S. (Priority Energy can prepare the HVAC design reports.)
  • Insulation must meet IECC 2012 levels (or state code requirement) and installation must meet RESNET’s defined Grade I. (Illinois is following the IECC 2018 code, which are stricter.)
  • Windows:  U-value .027 for CZ 5, no SHGC minimum.
  • Heating Equipment:  
    • Gas-Fueled Furnaces must have AFUE 95% at minimum.
    • Filtration with at least a MERV 6 filter and the filter access panel should be sealed by an HVAC contractor.
    • Boilers or Heat Pumps must have a minimum CZ 5: 9.25 HSPF/15 SEER/12 EER, air-source w/electric or dual-fuel backup. 
  • Cooling Equipment: AC must have a minimum rating of SEER 13.
  • Ventilation: A Whole-House Mechanical Ventilation system must be installed. Ventilation must meet the current ASHRAE standard required by applicable energy code.
  • Local Exhaust: Kitchen exhaust must vent outdoors at ≤ 100 cfm., and Bath exhaust fans at ≤ 50 cfm.
  • Blower Door/Infiltration Rates: 3 ACH50 in CZ 5.  (2018 IECC Illinois code is also 4 ACH50).
  • Ductwork: All ducts and air handlers should be modeled within conditioned space. 
  • Water Heater: Energy Factor (EF) for CZ 5 should be 40-gallon gas .61 EF or 50-gallon gas .59 EF (minimum requirement).
  • Lighting and Appliances: Dwellings must use Energy Star appliances and high efficiency light bulbs (i.e., LEDs, CFLs).

Energy Star New Construction Verification Requirements

There are three on-site inspections the HERS Rater must perform to complete the Energy Star certification process.

  1. Site Visit One - The Rough Inspection Before Insulation
    • Verify that windows meet levels specified.
    • Verify air barriers are fully aligned.
    • Verify reduced thermal bridging.
    • Verify air sealing meets Energy Star specifications.

  2. Site Visit Two - The Insulation Inspection Before Drywall
    • Confirm Grade I insulation installation and check additional design-specified insulation levels.
    • Verify that HVAC equipment and duct installation match design.
    • Verify and measure whole house ventilation equipment.
    • Verify duct quality installation and complete duct testing using one of the following two options:  a.) Rough-in:  The greater of ≤ 4 CFM25 per 100 sq. ft. of conditioned floor area (CFA), with air handler & all ducts installed.  b.) Final:  ≤ 8 CFM25 per 100 sq. ft. of CFA with the air handler & all ducts installed

  3. Site Visit Three - The Final inspection when the home is Finished
  • Conduct a blower door or air tightness test on the dwelling.
  • Conduct pressure balance testing in all bedrooms (achieve pressure differential ≤ 3 pascals).
  • Complete the Single-Family New Construction (SFNC) or Multifamily New Construction (MFNC) Energy Star Checklists.
  • Ensure the builder has met Energy Star’s National Water Mgmt. System Builder Requirements and complete the required checklist. (Priority Energy can help with design compliance).

    • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

    • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

    • I have a two story home built in the mid seventies. Lots of temperature fluctuation between the floors. The Aeroseal process dramatically increased the air flow to the second floor. Good experience. The company was very informative, answered a lot of questions.

    • Thank You so much for the super-fast turn around of our Manual J, D and S reprt for the Village of Glen Ellyn. Our original Manual J kept getting kicked back to us for corrections but your calculations/report got approved instantly-no questions asked and no more permit delays!

      Kim, Glen Ellyn, IL
    • Thank you. Truly. I appreciate you taking the time to clarify things for me and then going above and beyond to ensure that my CEUs are handled for our current RESNET cycle. You’ve always been kind to me and this is another shining example of that.

      Richard; Lake Forest, IL
    • On to the Radon issue - Excellent results with Aeroseal!  From 5 + to a .4.  Before sealing like we discussed, I had warm air coming out of the sump basket with the furnace running. Even with the furnace running, it is still pulling air in now.

      Bill; Belvidere, IL
    • Pat was awesome and super helpful! We are experiencing weak air flow in the duct system of our 1950''s home and Pat gave us great recommendations to fix the problem when we do our remodel.

      Bryan, November 2019, Chicago, IL
    • Priority Energy did a great job with an Aeroseal project for my home. The rooms are more comfortable and even throughout the house, including the far registers which never used to get significant airflow. Very honest and trustworthy

      D. L, Lake Zurich, IL Feb. 2019
    • Priority Energy did an aeroseal for our home. We have had issues with air flow in our kitchen (cold in the winter) and one bedroom upstairs (hot in the summer). After they were complete, there is such a stronger air flow from the vents, that it really makes a difference.

      J.J. Chicago, IL - November 2020
    • Excellent Service and Company to work with - highly recommended and professional!

      T. B. Chicago, IL - July 2020
    • Before we sealed our ductwork the rooms farthest from the furnace were always hotter or colder than the rest of the house. We felt an improvement in air flow to the kids rooms right away. 98% duct leak reduction!

      S. H. Glenview, IL - October 2020
    • The Energy Audit you did on last home was so helpful; we referred to it for years when we made home improvements. I'd like to have you do an audit on my new home now. B. A.
