Summary: In Massachusetts, our buildings use 54% of the energy we consume. This bill would improve buildings codes in Massachusetts to reduce energy consumption from residential and commercial buildings.
Why This Matters: The energy we consume still comes predominantly (over 90%) from dirty and dangerous sources – and the vast majority of energy used by our society is for heating and powering our homes and work places. To clean up our air, lower costs for consumers, and reduce our dependence on foreign oil, we need to make our homes and businesses far more energy-efficient.
A zero net energy building (ZNEB) is one that is optimally efficient and, over the course of a year, generates energy onsite using clean renewable resources in a quantity equal to or greater than the total amount of energy consumed onsite.
Zero net energy buildings are already being designed and constructed in Massachusetts, particularly in the residential sector. In addition to saving energy and reducing greenhouse gas emissions, zero net energy buildings can provide significant cost savings for residents and businesses, and stimulate clean energy technology development and job growth in the Commonwealth.
Creating more zero net energy buildings will require the state to find new ways to create clean and local energy, reduce our energy consumption, and remake our society to support a low carbon infrastructure. Zero net energy building will make energy efficiency and renewable energy technologies central to the way we design and build.
This bill was based on the recommendations of Governor Patrick’s Zero Net Energy Buildings Task Force, as the report states:
“Although the current economic and climate challenges before us are great, the opportunities presented by these challenges for technology innovation, job growth, energy savings, and clean energy in the building sector require Massachusetts to act boldly—the time is now to move toward zero net energy buildings in the Commonwealth.”
What this Bill Would Do:
This bill would direct the Board of Building Regulations and Standards (BBRS) to:
- Establish definitions of residential zero net-energy buildings and commercial zero net energy buildings.
- In consultation with the Department of Energy Resources (DOER) create regulations establishing a residential zero net energy building standard to take effect January 1st 2020 and a commercial zero net energy building standard to take effect January 1st 2030.
