Your Massachusetts Home Energy Scorecard What is HERS?
The Massachusetts Home Energy Scorecard (MA Scorecard) is a tool to assess a The Home Energy Rating System (HERS) Index is the industry standard by which a
home's expected energy use, cost, and carbon footprint.A low energy use generally home's energy efficiency is measured and compared with other homes. The lower the
means that a home has a smaller carbon footprint and lower energy costs.The MA score,the more energy efficient the home.
Scorecard also allows for comparisons of one home's energy use and carbon footprint.
This is because the energy use and carbon footprint are calculated without the influence An energy rating has been completed for this home by a certified HERS Rater who did

levels, air leakage, heating and cooling systems, major appliances, lighting, hot water
heating, and any electricity produced by on-site solar PV.The HEU number is
"normalized"in the sense that occupant behavior, which can vary, is taken out of the
calculation.A home's actual energy use will vary with number of occupants, occupant
behavior, weather, and changes to the home.

Duct Leakage Code Requirements for IECC
2009 IECC:
Postconstruction Leakage Test: Duct Leakage to Outdoors <= 8 CFM25/ 100 sq ft CFA.
Rough in Test with AHU:Total Duct Leakage <= 6 CFM25 /100 sq ft CFA.
Rough in Test without AHU: Total Duct Leakage <=4 CFM25 /100 sq ft CFA.
2012 IECC Mandatory, 2015, 2018, &2021 IECC Prescriptive Paths:
Postconstruction Leakage Test: Total Duct Leakage <= 4 CFM25 / 100 sq ft CFA.
Rough in Test with AHU: Total Duct Leakage <= 4 CFM25/100 sq ft CFA.
Rough in Test without AHU: Total Duct Leakage <=3 CFM25 /100 sq ft CFA.
Note: IECC 2021 requires Total Duct Leakage <= 8 CFM25 /100 sq ft CFA when all ducts
and air handlers are within the building thermal envelope.
2015 and 2018 IECC Performance Paths (Cost Compliance):
Leakage testing is required UNLESS all ducts and air handlers are located entirely within the thermal envelope.
There is no pass/fail threshold for duct leakage on the performance path.
