Massachusetts
Summary
Chapter 61 is a mandatory state developed residential code that meets or exceeds the requirements of the 2009 IECC. The stretch code is also a state developed code, which allows projects to voluntarily go beyond minimum standard and further reduce energy consumption by 20%. Energy performance criteria are outlined for residential buildings, addressing thermal envelope components and energy efficiency requirements for HVAC, hot water and lighting. The codes allow a prescriptive path or simulated reference-building calculation to show compliance. Compliance can also be achieved for the stretch code by meeting HERS rating scheme requirements.
The first building energy efficiency requirements for residential buildings in Massachusetts were adopted in 1975. In 2009, Massachusetts became the first state to adopt an above standard voluntary stretch code. The codes and surrounding policy systems incorporate a number of dynamic initiatives to improve energy efficiency, including mandatory air-tightness and duct tightness testing, renewable energy iniatives and special efficiency requirements for public buildings. Additionally, any jurisdiction seeking to be a “Green Community” must adopt the ‘stretch code’, with over 100 jurisdictions doing so as of December 2012.

Performance Codes for Refurbishments
Not entirely, the residential rule is that if you change a building component you are required to improve or replace it.
-
Performance Codes for New Builds
All new residential buildings are required to meet performance requirements of the HERS rating scheme (65-70 points), based on a comparison with 2006 reference building.
- Energy Declaration
-
Model / reference Building
A performance based code requiring a Home Energy Rating System (HERS) maximum index score. 121 municipalities have adopted the HERS Index Score. A 2006 reference home is used. A performance-based code for large buildings is also available.
- Mix of different models / Hybrids

Renewable Energy (solar, PV, others)
No requirement for Residential buildings, but it is encouraged. Commercial buildings or surrounding properties shall incorporate an on-site renewable energy system that supplies 3% or more of total building electrical loads.
- Local renewable sources
- Energy Offsets/Green Certificates

Compliance assessmentNotePartially, definitions of compliance in the US are fraught with inconsistencies. MA approach has been to move towards a performance standard as a way to better define and measure compliance. We have conducted residential and commercial compliance surveys, which illustrated higher compliance with the stretch code than the base IECC code despite requiring a higher energy efficiency level.
